KVM issue with monitor

Q: KVM issue with monitor

Ever since I setup a KVM switch to have 2 computers sharing 1 monitor/keyboard/mouse, I have had monitor problems.

There is a subtle but noticeable wobble/ wavey-ness thing happening across the screen when connected to one of my computers (my AMD).

Also, my display (with AMD computer) has a stretched horizontally look. I have tried different screen resolutions but they all give this stretched look which I didn't have before.

And my AMD used to give 1920 x 1080 as an option for max resolution, but this is now capped at 1600 x 1200.

Please help as this is very annoying & looks awful. The specs of the KVM switch say "Max. Resolution: 1920 x 1440. Bandwidth: 200MHZ"

My AMD computer:
Windows 7 64 bit SP1.
AMD Athlon II X4 620 2.6GHz.
4GB Ram.

Philips 226V3L.

Video card ATI Radeon HD 4350

Preferred Solution: KVM issue with monitor

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

What is the make and model of the KVM switch you purchased? I have tried lower quality switches at my work and found similar results. Ended up having to get one of the more expensive / better brand ones that solved the issues.

I have a dell laptop that has 1920x1080 resolution. However, i connect it to an external monitor that has 1920x1200 resolution. Basically almost everything i do is on my external monitor which acts as my main primary screen. Thus i do sometimes open some windows or drag a window or so to the other screen like youtube etc to the laptop screen.
My issue at the moment is everything is way too big on the laptop screen. I want to have 1920x1080 resolution but its way too big. I googled what is my resolution on it and it shows 1536 x 864. Can someone tell me how to change this to 1920x1080?
My external monitor which is my main monitor is fine at the moment with the 1920x1200.

Try updating your card drivers. Go into Device Manager and right-click on your display adapter.

I suspect that the cards are too old, though. We will see.

I have an HP monitor HP w 2207 that comes with a VGA cord. It worked great with my windows 7 laptop but
now that I have a new windows 10 that does not come with only usb connections I bought an adapter VGA
to USB and connected the monitor to a USB 3 port.
The monitor comes on for a second and says Monitor Going to Sleep and then the screen turns black.
The VGA adapter said I didn't have to install any drivers so I don't know what to do now. Help!

Here is my problem. I have a primary monitor and then I run S-Video out to the TV so I can watch video clips.

With Vista, I had no trouble starting a video clip in media player on the primary screen and then dragging it over to the second monitor (TV) for actual viewing.
However, I tried to do that with Windows 7-it won't let me drag Media Player over to the second monitor. I can drag other applications to the second Window (Word, Browsers), but not any media program. Even tried another media player application.

Not sure what to do-how can I get this to work? I want to be able to watch TV/Movies on my second monitor.

I have the dual monitor thing working and everything. I have my laptop and attached it using HDMI to a HDTV. The problem is that i cant get my desktop to my laptop. The HDMI cable, when plugged into my laptop makes the TV display the desktop automatically. Because of this, when i enable the dual screen, it extends my desktop to my laptop screen, and uses my tv for the main monitor. Does anyone know how to fix this?

Hi guys,

I just got a new monitor, it's a Samsung SyncMaster931B. I plug it in, and I just get a blank screen with a blue blinking light around the power button. No visuals on the screen at all, menu etc.

I then plugged it into my computer, booted it up and got the same thing. Just a blank screen with a blinking light around the power button.

I don't think it's my computer, other monitors work fine. I think the monitor is in standby mode, but after pushing random buttons, and moving mouse/keyboard nothing seems to wake it up.

A:Monitor Issue

Does it say anything about this in the manual? I would call customer support if you can't get it to do anything. Are you using VGA or DVI outputs on your video adapter? Make sure the monitor is plugged into the right port! Monitors are the one PC component that should just "work" when plugged into the video card so I'm stumped.

You can also swap the video connections (assuming they are both using the same type), just to rule out the video card. Aside from that, it sounds like a failing monitor.

Okay, some stuff that I forgot to mention because I'm just that tired today.

The monitor is connected to the HDMI out on the video card through a DVI -> HDMI adapter.

I experienced the same behavior before yesterday's upgrade when the monitor was connected to the DVI out on the video with the anchor screws in place so I'm thinking it's not a physical connection issue.

Thanks in advance.

Built this system in January. In June, system went to standby and never came out. Had the processor tested and confirmed defective and amd replaced. Just put new processor in and now my monitor is changing intermitently in color hues. White to purpleish. Did notice another post which seemed to point towards the monitor but I can't but wonder if any other possible causes due to new processor? Also been having heat issues with my UPS but the voltage/frequency seem fine as reported by the belkin software. It's a high watt model so I'm kind of surprised but it is summer and of course the UPS literature says use only in controlled enviroment (who has that?) Any thoughts would be much appreciated.

If you are testing the on board VGA output while the graphics card is plugged in, have you checked the motherboard specifications to see if it supports simultaneous video outputs using both video controllers? Many motherboards do not support such operation.

I have dual monitors setup with a docking station one using VGA and the primary using a DVI cable. The DVI seems to work fine, however, the monitor hooked up using the VGA cable which is setup using extended desktop shows tiny squiggly horizontal lines on it like it is interfering with some other device. It is hard to see but can become annoying. We have tried swapping out cables, monitors, surge protectors and power cables. Also the docking station. Does anyone have any suggestions on what could be causing this? The monitors are HP 1940T models. The laptop is a HP 6910P.

Any help is very much appreciated.

Are the symptoms re the monitor hooked up via VGA port recent or were they always present? If recent, did they present coinciding with something?

If you run the lappy without the docking station on its own with both monitors, does this change anything? If you hook up only the monitor showing the symptoms without the one connected via dvi, does THAT change anything?

Absent more info, feels kinda like some voltage issue.
Edit: If I found the right lappy, it is very new, core Duo, yes? Also indicates U have a 3 year warranty, yes? if so, I would SOOO immediately call HP. Serious investment, this setup, boy....and part of it paid for the WARRANTY.

THESE HIGH END LAPPYS...even my Alienware Sentia.. ARE PITCHED AS "DESKTOP REPLACEMENTS." WHEN PIGS FLY. Think JUST how many sleazoid parts are jammed into that pancake case and in wut proximity; think THERMAL ISSUES.

Hi everyone,
I've recently started having an issue where after I exit a game, my second monitor (laptop screen) returns to normal but my main monitor (Samsung 21.5", not sure of the exact model) displays a black screen. The standby light on the monitor is off, so the monitor is powered on however the screen remains black, with not even the backlight. I try turning the monitor off and on again but the problem persists, until I unplug my HDMI cable and plug it back in again. Although this might not sound like such a big deal, it's quite annoying because once I do get the monitor back up, my desktop icons are muddled up and my desktop background changes back to my old one (something that also happens while installing GPU driver updates).

Any thoughts as to why this is happening?

Sometimes this can be caused by the program controlling the refresh rates. Some cards have options to force refresh rates instead of letting the program control it. Check the advance properties of your vid card by right clicking on the desktop, choosing properties/ settings/ advanced button, and leafing through your graphics card settings. Next is to try to match the games to your desktop resolution, look in the game options to do this.

Here's a picture of what my monitor looks like at the moment:

I've noticed that my monitor has some kind of imprint in the background, like it's taken some kind of damage. It's been there for about a year but recently it's gotten much worse. I can only see it on some background, like I can see it very clearly on a webpage with a grey background but I cannot see it on a white background. It is very distracting and annoying when I'm trying to watch videos or even just browse the web on my computer.

Anyway, what kind of damage does my monitor have? Is this a part I can replace, or will I have to buy a new monitor?

A:Need some help with a monitor issue

I think I can safely suspect that this might not be a monitor issue at all, the problem may lay with your video card or adapter. Sometimes with older video cards or video adapters something with them goes all screwy. I've seen your problem once, maybe twice, and if I remember right, I think we had to shell out some money for another video card. I think the tech at Best Buy told my friend something about video adaptive ghosting, which is a problem created when some of the video cash or memory doesn't clear all the way, and an image is pertinently embedded inside the memory of the video card.There for leaving a ghost image of one of your prior wallpapers or such.

One sure quick way to tell if this is a monitor issue, take your monitor and hook it up to another computer, see what it does! Other than that, I'm suspecting a video card or video adapter issue!

Ps- while we are at it, why not tell us what type of computer your running, what video card or video adapter your using, what operating system your running and maybe how much RAM your using?

I have a Dell Monitor. Dell E172FP - Flat panel display - TFT - 17" - 1280 x 1024 / 75 Hz - 0.264 mm - VGA (HD-15). It fell on the floor and was fine for a while then it started to go blank every once and a while. The power button would turn orange then turn off, repeatedly. When I wacked the sides of the monitor while the orange was lit it would go back to normal. One day when I came back it was just all black and the power said it was on. When I turn it off then back on, it is on for a second then turns black. However it isn't completly black. If you look really hard in the light you can still see everything on the screen. I don't know what is wrong and any help would be greatly appreciated.

The backlight isn't turning on and staying on, probably due to a problem with the inverter that powers it. "When I wacked the sides of the monitor while the orange was lit it would go back to normal" could just be a loose connector. If you have experience repairing electronics equipment you might be able to fix it. Otherwise, contact Dell if it is under warranty.

Got a monitor issue, and I'm wondering if anyone could maybe narrow down what the problem is a little bit.

After my computer has been on for a little while, the screen will intermittently jump left and right, maybe a pixel or two. It will do it two or three times then stop, then do it again a little while later. Has a tendency to get visually annoying. The monitor is a Gateway 2000 EV700.

Any suggestions? I know this is rather open ended, but I'm hoping to narrow down the issue to a certain area at least.

Thanx in advance.

A:Monitor issue

Its probably the monitor. Can you test the monitor out on a friends PC or try a different monitor on your pc? Then you can be sure where the problem is. If the problem follows the monitor its probably best to buy a new one as repairs inside a monitor are dangerous due to the high voltages inside and you can probably buy a new one for what it costs to have a monitor repaired.

It looks like you have the wrong screen resolution. According to you System Specs you are using 1600x900. Most of the latest monitors use 1920x1080.

Just purchased brand new Dell XPS with windows 10 and have been trying to hook up two (1 new) monitors. Windows only recognizes (1) monitor. Have tried to update drivers and that has not helped.

A:Win. 10 monitor issue

Which exact XPS did you buy? Provide either the model number or even better the Service Tag.

What ports do each of the monitors have, which ones are you trying to use, and what ports does the computer have?

Does the system have a dedicated graphics card and integrated graphics? If so make sure you are connecting both monitors to the graphics card and not one to each, in most systems if there is a dedicated graphics card then the integrated graphics will be disabled and not usable.

I have a problem with my new monitor and XP/Vista

I have 3 PC's hooked to the same keyboard/mouse/monitor through a KVM switch. I used to have a 19" CRT at 1280x1024. I would power up each PC at the same time and then log them in 1 by one switching the inputs. No worries on any of the PC's.

However since I got me new HP LP2475w 24" LCD monitor which likes to run at 1920x1200 I have been having issues. The PC that has the monitor active boots fine into 1920x1200 but the others boot into a 1600x1200 mode and make the screen offset. If I boot each one with the monitor active then there is no issues but it takes much longer as I have to wait for each one.

How can I force them to stay in the 1920x1200 mode that I have set in the display options?

A:Monitor Issue

when the screen gets offset, have you tried to press the AUTO button on your monitor, to bring the screen in place? It must memorize this setting and keep it for later views.

Can you plug it in to your pc in a way that can allow it to be turned on seperately from your pc? In this way it may have a chance to warm up, and may work properly.

I'm having a problem and I think it's my monitor (details are in place).

From a cold boot, I turn on my monitor and the display goes black after 2-4sec. I know its not going into Sleep mode as the light behind my power button flashes in Sleep mode and it's not doing that here.

After turning my monitor off, it does the same thing again a few times before it stays on. After that its ok for however long I use it, even in games and whatnot.

My monitor is over 5yrs old so I'm guessing it's just that time, but wanted to ask here first.

Thanks in advance....

I agree, it might be failing, but you could try installing your driver for it, reboot with monitor on and see if Windows can grab a better driver.
Try the monitor on a different PC if possible. If you get the same issue I would say that would fault the monitor.

While it goes through the BIOS screens, Window screens, will keep flashing on every time it reaches a new screen, but instantly goes black again. It also makes a very slight beeping sound coming from the back of it. I tried shining a flashlight to see a dull image, but I don't see anything. What could this be, and is it worth replacing or just buying a new monitor? Thanks!

When I upgraded Win 8 to 8.1 I lost my 2nd monitor.Computer doesn't recognize second monitor No hardware was changed and both monitors still hooked up to computer. When I go to "screen resolution" via desktop it only shows a #1 .
When I flipped the monitors around so that my #2 is now #1, it sees that. So I know it's not the hardware.
Ideas OH WISE ONES????
Thanks in advance

Just installed a new HP Monitor, Model # 27vx IPS. I now have a pixel line along bottom of screen.It looks like the top of he task bar when it's hidden. In certain games it also appears on the right side of screen.
I tried updating driver and its still there. I even did a fresh install of window 7 and it didn't fix the issue.
I'm thinking I might need a new graphics card. My current card is a ATI Radeon HD 4200. Any suggestions ?????

Hello all of the tech guy forums. Im currently making this post on my phone due to issues im having with my computer. The computer powers on, but doesn't recognize the monitor and thus I have no display. I have a converter connected to my video card and monitor. I tried cleaning out the tower mutiple times, check power cords and connections, and have had zero luck. The last things I did on my computer before restart was dskchk via cmd and update realtek audio driver. - if that is useful

Since it seems to work when not being tasked (for lack of a better term), it would seem to me that the video card is on the way out...

A question if I may...

Are you over clocking the video card, and can you check to see if there is a fan on the video card and see if it is running?

Sounds like the video card is over heating to me...

Of course you could try another monitor (if you have one) and see if the problem happens on that one as well...

I have a Dell 19" monitor connected to my compaq tower. The video card went out, so I installed a new pci card. The Monitor the gave me a 2" wide backgroung on the left side of the screen, and the rest of the screen was white. I Moved the cursor of the mouse over it, and was able to drag the background bigger (which I have never seen before).

try the monitor on another system. if you still have issues, the problem is your video card or motherboard. Even if you replaced the card, your system may still have something wrong. I would also try a new video cable.

Hey, so towards the beginning of this year I purchased a refurbished HP pavilion f1703 monitor from a local fix shop. One day while playing a game that ran somewhat slow due to my old computer it shut off and went black on me. Ever since I have tried to find a solution and have had no luck. The monitor will load the dell startup and show bloot into safe mode/startup repair (sometimes) but may randomly cut out. Also tried factory resetting the monitor for lower resolution and it might stay on abit longer before turning black again. The PC works on a TV, but the monitor shutting off after loading screens and even more delayed after lowering resolutions confuses me. Any ideas? Thanks.

When i woke up this morning, well you can't see in this picture, but on the far left side of my desktop screen, there is a bright white looking line, its like part of the monitor size is cut off or something, can't really explain it. But if you look at the ati thing, the screen resolution is in the middle. The screen refresh rate is at 60hz, even tho i get a warning message in pcwizard that i should change it to 70hz, but i don't think that is accurate.

Anyone know what the issue could be?

My computer monitor will sometimes take 15 minutes to turn on when starting up my computer. It will flash on for a split second, then go black for a couple seconds and then flash back on and continues like this for some time and then will finally turn on and work all day like nothings wrong.

Hello Matt and welcome to the forum!

Are you sure that this isnt a monitor/connection issue?
Whats the make/model of the system?

If this is a tower (I assume it is) turn off both the monitor and computer then reseat the video cable on both ends.
Make sure that the connections are finger tight, just enough to hold them into place.
If the issue persists see if you can try another monitor on your system.

You may well be infected but to me this sounds like a monitor.

You have either display settings that are outside of your monitor's capabilities or corrupt video drivers.

In safe mode, look over the display settings. If those look normal, uninstall your current video drivers and/or set the display adapter to use standard VGA drivers.

i have this older packardbell monitor
and whenever the monitor is used for 5-10 minutes, it starts turing off and on? is this caused by lack of power, or.. ?

A:monitor issue

possible heat related and on the monitor - as it heats up with use a component goes faulty.

On some monitors the video card appears to turn the monitor on/off and you get a yellow/green led change - when it goes off does the led go off - you could try unplugging monitor from the video card and leave it on its own - if it goes wrong after 5-10mins then at least you know its not the PC video card causing the display to go on-off

If you can hear windows starting up when the monitor does not come on I would say the monitor is dead or dying.

I just upgraded to Windows 8 on my HP Pavillion dv6815nr. I am not having any luck connecting it to a second monitor. I followed the basic steps under "screen resolution", but my computer is not identifying the second monitor. I read that you need to go to Nvidia's control panel to connect to a second monitor, but I cannot seem to find that with the driver I currently have installed. HP's website does not have an update for the Nvidia driver for Windows 8 for my particular computer. I am using a VGA cable if that makes any difference. The computer originally had Vista and I never had any issues connecting to a second monitor. Does anyone have any useful pointers?

These drivers are very generic....

Install the latest nvidia drivers from either nvidia or from your laptop manufacturer.

When i installed Win8 on my Compaq Presario, Windows update offered a new Nvidia video driver to install.

Did you go into Control Panel - Display - Screen Resolution, then click on 'detect'?

Mind you, i'm using a USB adapter to connect a 2nd monitor since my video card only has the one output. Even then, when i connected via USB, Windows automatically installed the driver.

I am running a Lenovo X60 thinkpad with XP Pro, along with an external Viewsonic monitor connected through my docking station. I used to use the Viewsonic as the primary monitor, and the laptop monitor as secondary. Then a few weeks ago when I re-docked my computer the external monitor wouldn't come on. When I go into display properties & try to make it my primary (or my only monitor), it just comes up with a no signal message & goes black. I can activate it as my secondary monitor, but not my only or primary. Also, if my eyes are right, the resolution on the viewsonic seems worse than before.

At home, I run dual monitors. So when I am there, there are programs that open in the right screen. Before I left the area (and intended on bringing just one monitor) I used my setting to change the setup back to using 1 monitor.

However, while Trillian seemed to recognize this change and moved over to the left screen, Vent did not - it opens off to the right (where it can not be seen as I am now only using one monitor). So the question is, how do I get Vent to open on the single (left) screen I have now that I am away from home (and dont have access to another monitor to plug in to simply move it back).

I think it might have something to do with when you shout the lid on the laptop. Once the lid is closed there is no power to that screen and subsequently no power to 2nd monitor because of the lid being closed. There might be a setting to change/play with on the laptop as to what happens when you close the lid of laptop.

Ok I am using my tv as a second monitor. Ever since instlaling Windows 7, it identifies my desktop monitor as 2, and the tv as 1. If I use the shortcut Win Key + p, to switch monitor setup (extend, duplicate etc...) to "Computer Only" It will make the tv the primary, not what I want. I can switch the connectors at the back of the card for this to function correctly, but then when the computer boots it treats the tv as primary (so boot up sequence shows up on tv), this is also not what I want.

So is there a way to manually set the identity? (so that my monitor is 1, and tv is 2). I tried unplugging the tv, and using a single display which gives the monitor an identity of 1. As soon as I plug the tv in it gives the tv an Identity of 1.

I wanted to change the settings so I could use the TV as the primary display when connected, so attempted to change the settings i evidently did something wrong, now it won't work at all, additionally when i plug the HDMI cable into the PC the monitor just starts flicking on and off and won't display anything on the TV.
Is there a way i can make the computer 'forget' the TV so if I reconnect it, it can go through the new display wizard again to start afresh?

A:Another Multiple monitor issue

Any ideas guys? I've trawled the net for ages trying to find a soultion but am not getting anything helpful... basically I'd like to reset my display settings so it can re-detect a new monitor and things would be lovely....

My monitor resets itself(like when you do a resolution change, where it flicks off and on) every time I interact with anything to do with a video setting, or right click any movie file(mpeg, avi, etc). Tried updating my drivers, but this didn't help, Just started recently, and I'm totally stumped as to what would cause this.

Nothing hardware wise has changed, and I havent installed any new software of which I'm aware. Preliminary virus scans havent shown anything, and I plan on a 'just in case' defrag tonight. Running XP pro on an AMD Anthlon 2400+ with a Geforce FX 5700 Ultra and a gig of ram(single stick).

"If your PC&#8217;s graphics capabilities are built into your computer&#8217;s motherboard, they will often be disabled when you add a graphics card. You may need to disable it via the system BIOS (Basic Input/Output System)

Does this mean I cannot use my built in video card?

Hi, my dad has an old Dell monitor that has vertical white lines and the screen is squished left and right. The hard disc seems to be working ok. If I turn it on and move a window left and right, the window looks like it's passing a convex glass to a normal glass and then back to convex. Left and right side of monitor are distorted but the middle seems fine. Is this a video card problem? If so, how much will it cost to replace?

Thank you guys!

Hello and welcome to Techspot.

Sounds like you monitor may have gone bad.

Can you try your monitor on a different system?

A friend of mine that is not what I would call, "Computer savvy", changed his Nvidia settings to set his monitor as his TV. Without having any visual on the television he saved the settings on accident. At this time, when we start the computer, the POST screen loads on the working monitor but once Windows starts the monitor turns off.(Like it is switching the the TV that is not plugged in and is not working properly.) I am able to log into safe mode and VGA mode, but unable to load the Nvidia control panel in either of those. I need to know how to set his monitor back to the default monitor without being able to log into Windows regularly.

P.S. It's Windows XP, I am not at the computer at this time so I do not have any other specs right now.

Is it onboard graphics or a graphics card? If its a graphics card you can try to unplug the monitor from it and plug it into the onboard graphics port

My problem is that when vista ask for permission to open any program my monitor blinks for a nano second( monitor turns black) otherwise the system is performing good. Is it the problem with the old CRT monitor or some kind of driver problem. My system configuration is written below.

A:Monitor blinking issue

Hi harmonSmith and welcome to Vista Forums

This is normal for some systems, depending on the hardware and drivers. When the display comes back on, is it dimmed with the UAC dialogue box present? If so, then this is known as the Secure Desktop. This is not the desktop itself, rather it is an image of the desktop which contains no clickable content, save for the UAC dialogue box.

I recently bought a new monitor (Benq XL2430T) and sometimes it goes to this(Look at the picture). I wanted to check wether it is a pc issue or monitor issue so I switched the 2 dvi ports (I have 2 monitors now) and the monitor still looked the same once it got connection with my computer, while it was disconnected it gave me a black screen. My computer is 4 years old and is pretty outdated since I never upgraded it. It had some issues with it in the past so it wont suprise me if it was computer's side. Can you help me? Thanks in advance!
!!BTW, this always happens in the beginning of when I start up my pc, once it has been running for a while (aprox. 15 min), it wont happen.

I've been experincing some trouble with my monitor. 19" Widescreen. I know that the issue is to do with the settings I have the nVidia 9800GT set to. Okay what happened was I moved my AcerPower FH over by my HD TV. The computer booted and displayed things on it, but when I was fiddling with the resolution and dpi, I acidently set something too high and now the TV won't display anything other then Startup and nothing past that, (The welcome screen). So I switched back to my regular monitor and I got the same thing. I tried switching back to integrated graphics to reset the drivers, and nothing happened at all. I know that the issue is with the programmed settings, but how do I restore those settings to somthing that will work on my computer? Any help please?

A:[SOLVED] Monitor Issue.

You need to load in to F8 on boot and select "enable vga mode" and press enter. This will likely help. If not than do F8 ->safe mode and uninstall the display adapter driver and reinstall it (make sure you have the driver cd before uninstalling the driver).

I'm becoming seriously frustrated.

My problem is very akward and hard to clearly explain, so please bear with me.

On the right side of my screen it is possible for my cursor to venture into nowhere. Also it is possible and happens almost all the time, that whole programs start up on the right side of my screen and beyond. This is very frustrating because I have to repeatedely click and drag to the left to attempt to get my program on the screen. I know this is somewhat confusing, but please give your time to help me out. Thanks!

Reboot tapping F8 there should be an option on the options screen "Repair Your Computer" follow the process Windows will attempt to fix any problems. If it can not find any problems in the list of other options, select "System Restore" Select a Restore Point prior to install Java or any option regarding java before the issue started.

A:Monitor Issue (goes dim randomly)

my computer has the same problem somewhat (screen stays dims and becomes bright occasionally) I tried changing my monitor's output level from 0.7v to 1.0v and back with no permament change, changing this level will temporarily fix it, but after a few minutes it dims (or brightens) again .. I'm no electrician, but I think it may be faulty wiring

I've just installed Vista Beta 2, and I'm having trouble with a dual monitor setup. I'm using an nVidia GeForce FX 5500 graphics card (128 MB of memory, 2 VGAs out, and one S-Video out).

My goal is to connect two monitors like this: my main VGA monitor running at a very high resolution, and a TV at a lower resolution, connected via S-Video. I've successfully gotten the desktop to span the two monitors like this, but every time I reboot, both screens show the same desktop, both at 600 x 800. I need to manually change the resolution and desktop settings each time I reboot.

Is there some way to get my dual screen settings to "stick" from session to session? Any help would be appreciated.

A:Dual Monitor Issue

I'm no expert but it sounds to me like the e-bay bought adapter is missing a few wires that would be used to ID the monitor. If you download the manual for your video card from the manufacturers web site you should be able to figure out what max resolutions are supported. I think its the adapter not a screen resolution problem.
