No signal when connecting displayport to hdmi converter to S...

Q: No signal when connecting displayport to hdmi converter to S...

Hello. We have connected a HP 8200 Elite to our Samsung TV with a displayport to hdmi converter 1 year ago, and it worked well. A week ago we bought a new TV table and after reconnecting the HP 8200 to our Samsung TV we get no signal to the TV.Yesterday I tested to connect a HP monitor with displayport to the HP 8200 with a displayport cable, and it did work.Today I was and switched the displayport to hdmi converter at the Kjell & CO reseller, BUT WE STILL GET NO SIGNAL TO THE SAMSUNG TV. I have connected a monitor with the RGB contact / cable, and have tested to change the display settings to make it work, BUT WITH NO SUCCESS. Could a straight displayport to hdmi cable solve the problem? Regards Roger

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 http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Are there any adapters to do this or ways to do this? I can't seem to find any.

I am buying new monitors, the dell u2414h. Now, while this does have hdmi, I will be connecting multiple monitors together to extend the display from the laptop to give me multiple screens. The problem with this is that it only works if you use displayport and not hdmi, so I need a way to convert the hdmi to displayport or mini displayport.

I will primarily be using these monitors with my laptop that has displayport, so that is why I am getting these monitors and that won't be a problem. I will most likely hook up other laptops to the monitors and hdmi is way more common from what I have seen on laptops than displayport and is why I need a way to go from hdmi to displayport or mini displayport.

Any ideas? Thanks.
 

A:Hdmi to Displayport/Mini Displayport

You can't, HDMI does not support daisy chaining in the manner that DisplayPort does and you can't use a simply adapter to go from HDMI to DisplayPort and get the features of DisplayPort.

I replaced my monitor with a Dell that has VGA, DVI and DisplayPort. My PC outputs VGA or HDMI, so I'm using an HDMI to DVI cable(previous monitor is VGA and DVI only). My only gripe with this cable is that the DVI end is hard to attach/remove. I can get HDMI-DisplayPort cables or adapters, this would be so much easier to deal with than trying to screw that DVI cable in place, but I need to know if outputting HDMI into the DisplayPort is going to cause any issues with picture quality.

I see either dedicated cables or converter boxes on eBay, converter box would be cheaper and I can use whatever HDMI cable I have on hand.

A:Displayport/HDMI to 1080p LCD TV

Hello & welcome to sevenforums,

What's about duplicate the laptop screen over the Hdmi cable in the Windows 7 display settings, not your video card drivers?
So the laptop will be overscan, but not the digital TV that will have the full screen without any black borders or cutted edges.

But looks the duplicate display will stay at 1366x768 / 60hertz, 32bits colors.

Hi, I just installed my windows 7 (64x) again (after formatting the hard-drive) but now I have a problem with the audio from displayport to hdmi. I can't transfer the voice from laptop to TV anymore. I checked almost everything. Disabled the video and audio cards, set the AMD HDMI output as a default device or even disabled the rest but nothing worked so far. My display: AMD mobility radeon HD 5000 Any suggestions?

Hi @sasan79, Thank you for your inquiry. I grasp that you have formatted the drive and reinstalled Windows 7, but now you do not have audio on the TV.  Previously it was working fine. Have you done all your Windows updates?  Have you run the HP Support Assistant?  Have you run the Windows troubleshooter? Here is a link to HP Notebook PCs - Troubleshooting HDMI Display and Sound Issues that may also help. Please let me know the results. Please let me know if this resolves the issue by marking this post as "Accept as Solution".  To simply say thanks, click the ?Thumbs Up? below!    If you require further assistance let me know and I will gladly do all I can to help.

On my ThinkCentre M92p which has Windows 7 pro installed I am using a standard monitor from the onboard VGA.
But now I want to run a 2nd display to my LCD TV. So I have a new cable into the onboard displayport and the other end is HDMI into my TV. Nothing showed on the TV (no signal). So I went to the display settings and click on Detect but (Another display not detected) came up. Then I went into BIOS and set up the video to Multiple Displays. Still No Signal.
As far as I know I have the correct drivers for this model from the support downloads. Driver (b2vdo41us14.exe)
I am hope now someone can guide me through what I am doing wrong. And be thankful for any input.

I am trying to connect the HDMI port on my nVidia GeForce GT 640 video card to the DisplayPort input on my HP Compaq L2206tm monitor. This is the reverse of what is expected by cable fabricators who have lots of cables and adapters for the opposite configuration, i.e., DP on the videocard and HDMI input on the monitor. There seems to be a uni-directional vs bi-directional issue involved with DP, but I don't quite understand it. Anyway, the uni-directional choices I am seeing are in the wrong direction. Anybody dealt with this and what is your advice for me?

I own an HP 8440p with the NVS3100 graphics card. I have tried all suggestions regarding getting the DisplayPort to pass audio through a DP-to-HDMI adapter with no success. I have even tried purchasing multiple adapters in the hopes of findingone that worked, even HP's own pricey adapter.  Can I conclude that it is now settled that the HP 8440p with the discreet NVS3100 (not the integraed Intel Graphics) simply cannot be made to pass audio from the DisplayPort to to an HDMI adpter? If the answer is that it cannot then I will start shopping for a new laptop with a native HDMI and not the troublesome DisplayPort. Thanx, Redlyne

My specific question is:

which adapters would allow me to connect 2 additional dsub 1900*1200 monitors to both the hdmi socket and the displayport socket, so that i run a total of four monitors.

I have seen this :
HDMI
PC HDMI to VGA SVGA RGB HDTV Video Cable Converter Adapter PS3 XBOX 360 Apple TV | eBay

and this
displayport
Display Port Male to SVGA/ VGA Female Adapter Convertor Changer Cable Lead Wire | eBay

But i am unsure whether they would both allow me to run a further 3rd and 4th connected pair of dsub monitors.

Can you advise?

Hello:
1) I recently bought a  Dell Precision M4700 that has a Displayport, HDMI and VGA ports.
2) I also bought a Dell monitor U3011 that also has Displayport, HDMI and VGA port.
When I use VGA cable with VGA ports I am able to use dual (laptop screen and U3011).
But I would like to use Displayport to connect the U3011 to laptop. This setup used to work fine until yesterday.
Today I am not able to view/use my U3011 when I connect via Displayport (works fine with VGA).
How can I make laptop detect the U3011? The monitor says "there is no signal".
 
I don't have another laptop or monitor to troubleshoot the issues.
Here is what I did:
1) Upgraded the BIOS to A08
2) Upgraded NVIDIA Quadro K2000M Driver to version 9.18.13.1150
3) Upgrade other device drivers to latest releases.
 
Your help is much appreciated.

If you do not have the disk please use this link to install the drivers for the U3011 monitor: http://dell.to/146JzDi
Click the above link, select the operating system, click Download file and install the drivers listed by following the onscreen instructions.
Try changing the input source to DVI by using the monitors “Onscreen display menu”. Refer this link: http://bit.ly/ZLAcno
Also please try a different Display cable to check if the problem is with the cable itself.
Kindly let me now the results.

Using XPS 15 (UHD, i7) 9550 with a Monoprice USB-C to Displayport cable hooked up to a Dell U2713HM monitor.  Performance is great, except every now and again, the signal drops for a few seconds, turning the screen black. After a few seconds, it returns.  Not sure if this is an issue anyone else has seen.  Graphics drivers and BIOS are updated to the latest versions.

Other inputs like the power adapter and the wireless mouse I attach to the docking station do work however. I'm not sure what else I'm looking at. I haven't tried using the other inputs like the hdmi (id have to buy an adapter) or the VGA and the one other one it has since I dont have cable for those... I'm not sure how to resolve this.

Hi Peoples,
I just received my new Dell UltraSharp u2412m monitor!
Now I try to connect my Dell XPS15 laptop (via its mini displayport connection) to my new monitor via a mini displayport to displayport cable.Sadly it doesnt seem to connect and the monitor instantly goes into Power Save Mode...
What am I doing wrong here? Is this possible/compatible in the first place?
Thanks very much in advance!
Moris
Ps. the monitor instantly works with an old laptop via vga connection...Plug and play...

A:Problem connecting my XPS15 laptop to my u2412m monitor via displayport

Try using a different connection--hdmi would be best if the laptop has that. You can use a hdmi to dvi cable--same technology and those work. Those can be bought for less than $10.

On the XPS 15 9550, can an external monitor with Displayport inputs be connect directly into the laptop's USB-C Thunderbolt output using a straight miniDisplayport-to-Displayport cable?  Similarly, can a miniDisplayPort to VGA adapter cable be plugged directly into the USB-C Thunderbolt port to drive older monitors/projectors? Or is the TB15 Dock mandatory in order to get the computer talking to  external video devices through its Thunderbolt port output?

might as well buy a dvi cable. they should be cheap (hard to find tho inh my experience but should have came with your monitor.) its the same thing as HDMI, minus no sound. if your monitor had sound it would have possible came with one.

as for VGA vs DVI. you will defiantly get a better picture since analog does not compare to digital.

This laptop is 7 years old. Your TV is way newer and has far better resolution. the laptops Native resolution is 1024X768, the maximum resolution is 1280?800. Also since you are going through VGA this reduces the resolution and you will not get HD resolution (eg) 1080I-720P only a DVI or HDMI connector would get HD resolution.

hi all,

I have my media center PC connected to a Sansung LCD TV through an HDMI cable.
Everything works fine; the PC detects TV and both audio and video travel through the HDMI cable from PC to TV

The problem happens when I turn the TV OFF and ON. In this case, the video is back but not the audio. This can be seen in the "playback audio devices" in "control panel", the icon that represennts the sansung speakers via HDMI dissapears.
Any idea of what to do? I got the latest video driver, which also deals with HDMI audio but no luck at all...

A:HDMI audio problem when connecting LCD TV to PC via HDMI

This is more of a HDMI handshaking issue than a Windows or driver issue, and a very common occurrence. Sadly if you do a Google search using "hdmi handshake no audio" for the search terms, you'll get lots of results but very little in the way of how to solve. About the best solution I came across is this one,

*Official* Asus Xonar HDAV1.3 thread - Page 271 - AVS Forum

A lot of that thread deals with the Asus Xonar sound cards, but there is also quite a bit about the no audio in general.

Hi there

Brilliant little device for passing HDMI (less HDCP !!) plus RCA L, R Audio and 5.1 Optical Audio (SPDIF). Switchable audio pass thru,, 2Ch, 5.1 ch.
(Max HDMI input is 1080p so won't work for your 4K huge TV's though) - still an excellent little device for those who want to record from HDMI video.

(IMO the cheap ones are better than the expensive boxes as the expensive boxes don't strip HDCP from the HDMI output making some content not re-cordable with video capture devices or even software such as Audials).

AGPTEK HDMI converter. 21 EUR

AGPtek 1080P HDMI to HDMI Converter - Newegg.com

Audio quality more than good enough for games, movies etc. A really discerning audiophile might not be 100% satisfied - but it's not intended for Studio quality !!! More than good enough for me and I'm quite fussy.

Cheers

Nothing shows on the external monitor no matter what I do or try on either the laptop or monitor?  I have tried this on a Dell E7000 series laptop also with no result on that one either?
Does the HDMI port on Dell laptops support video or do I need to utilise some other means of connecting a second monitor.  Bear in mind there is no VGA output on these laptops.

With Vista, I ran the video with a DVI cable and audio with an SPDIF optical cable to a converter box that changed it to HDMI then ran it into my amp (Onkyo TX-NA906X) into my HDTV (Pioneer Kuro PDP-6010HD). Originally, I had to add a 1920x0180 res but it did work. Once I updated to Win7, it will not display any video beyond the initial startup screen (no HDCP???) so I can't see the login screen. Any ideas would be appreciated.

A:Connecting Laptop to TV with Converter

You need the reverse; a VGA to S-video or RCA converter like this; http://www.newegg.com/Product/Product.aspx?Item=9SIA07R07J3230

Also, there are simple VGA to S-video cables like this: http://www.newegg.com/Product/Product.aspx?Item=9SIA1NV0XD9387
But these only work if the graphics card/chip support such a conversion and most no longer do.

And don't forget you will need a separate connection, speakers, or use the internal laptop speakers for the audio.

Also lastly the image quality will suck. Older TV's using such inputs will max out at 1024x768 or more commonly 800x600 and the image won't be very crisp.

When I plug in the HMDI cable, nothing happens, that is, no display on the TV. I even doubled checked everything-input, cable!

Am I doing something wrong here? The TV is a Hitachi L32S02A.

The cable is HDMI 1.3 one.

I even tried the new PC which has my Radeon HD 6770 on it-still nothing!

What should I try now?

Hello everybody First of all I d like to say that I am not very technically savvy so I apologize for any ignorance on my part I posted this HDMI Signal No issue and a follow up on another forum however that forum seems to No HDMI Signal be a little on the dead side so I decided to ask you experts For that reason I am splitting this into the two days I have spent trying to figure this out to no avail Day So basically I ve been connected up to this quot Emprex HDTV for a few days nothing great use the nice Samsung for the PS with no problems well ok one problem While fine at first yesterday the computer decided to stop picking up the HDMI audio with Windows listing it as quot unplugged quot I tried uninstalling reinstalling and rolling back the drivers as well as installing new ones Realtek not sure if it had anything to do with anything but it was worth a shot to no avail That was only the start of the problems however This morning everything except for the audio of course was peachy A few hours ago however the TV decided to just stop reading the HDMI signal all together No video no picture no nothing All I get is a blue screen that says quot No signal quot I ve tried numerous cables unplugged and replugged countless times uninstalled and reinstalled all the drivers and nothing VGA works though so that s what I m using now By the way the problem occured after I had moved the TV to a new spot so it s not like I was in the middle of using it and bam down it goes I was extremely careful with the TV though so I doubt that the moving damaged the port I m not entirely sure if it s a TV or PC problem but until I understand what is going on I ll call it a PC problem So any known solutions for this sort of thing And if I ever get HDMI working again how about the audio I m using an ATI Radeon HD connected directly to the TV s HDMI port via the HDMI cable Windows Processor is AMD Athlon X Duel Core Motherboard Well I don t have a clue If it s necessary how do I find out the specific manufacturer model Uhhhhh all the drivers are recent Anything else you need to know Day It s certainly not a cable problem I ve tried different cables and none have worked The hardware seems to be fine and after days of messing with this crap I m positive that I wouldn t have missed something such as incorrect inputs However something I don t understand has come up I hooked up the computer to my Samsung TV and it worked beautifully so I then assumed that it must have been a TV problem broken port perhaps But then I plugged in an HD capable DVD player i max into the quot broken quot Emprex and everything worked fine After this I would assume that the TV and video card simply aren t compatible but I KNOW that this PC worked with that TV before and with the same cables I have been unsuccessfully trying with On the positive side by randomally clicking around I somehow managed to make the VGA output at x cluelessness FTW and all of my games worked as well until I decided to change the resolutions in the games Now no matter what I do or how many times I reinstall them or delete registry entries I get a blue screen and quot VGA not supported quot No matter what Well at least I can access the desktop o Apologies for the length Maybe this is a trivial issue or maybe it isn t but this has been quite the epic battle for me I m hoping you guys can help give me an idea of what to do and layman s terms for anything more complex would be nice Thanks in advance nbsp

A:No HDMI Signal

when u connect the cable to your laptop, do u hold down the fn key and click on the monitor key up on top? I think its one of the F keys? As fas as audio goes, you will need to go to your audio setting and choose HDMI .Hope that works for u.

I have a new 40" LCD Dynex TV with HDMI connections and a one year old Acer computer with Windows 7, which has an HDMI terminal. I have tried to connect the two, using all kinds of combinations of plugging in the cable before and after the computer starts or the TV is turned on etc. I have gone into the display on the computer and see that the computer recognizes the TV as a device and it also indicates that it is working properly, but I get absolutely no signal at the TV. I have tried different resolutions and different recovery rates, but to no avail. I know that the connections are good and that the TV input mode is the correct one.
I see in the "display" function of the control panel that two monitors are shown - one for the TV and one for my computer monitor.
Can anyone help me?

A:HDMI - no signal

Start by calling Dynex and ask what "mode" the TV should be in to receive.

Hi

I have just built a PC with the ASUS M4A88T-M motherboard which has Radeon HD 4250 on board graphics. OS is Windows 7 Pro.

I have installed all the motherboard/graphics drivers that were supplied on the CD, but I cannot get any video or audio output from the HDMI slot.

I know that there are sometimes issues getting the audio through the HDMI cable but there is no video signal either. The VGS & DVI slots are fine, and also using a DVI-HDMI cable works, but then I have to use separate audio cables.

Do you have to enable HDMI within Windows anywhere ?

I have tried two different TV?s with no signal on either, so it seems to be a PC issue.

Any help appreciated.

A:No HDMI signal

You can try to download the latest drivers from here:ASUSTeK Computer Inc. - Motherboards- ASUS M4A88T-M/USB3

Failing that, You can try to exchange the motherboard (for OEM Windows 7 to activate the replacement board must be the SAME model), or look into getting a video card

Hey,

When I connect my PC to my TV Via HDMI Cable, my TV does not receive a signal. When I check in Control panel>Display>Resolution, My TV hasn't even been detected. My TV is an LG 50", Card is a GTX580, and my OS is Win7.

Also, when I connect my laptop to my TV via HDMI (Also on Win7), It is instantly recognised and automatically displays, so it has to be an issue with the PC itself.

Spent a while on google trying to find a solution, but unfortunately I couldn't find one. Thanks for any help on this.

A:PC To TV via HDMI. No signal.

Hi there
What do you get on your MAIN PC when you press the windows + P key. It should be settable to display on 2nd screen only.

It should allow you to switch monitors. The monitor probably isn't being recognized since your PC is set to display on your main screen only (by default).

Ensure the TV is switched on and the input set for HDMI. You'll probably have to change the resolution - laptops seem to work fine --desk tops seem to be different -- probably because of the difference in the graphics cards - especially built in ones.

Laptops recognize when a monitor is plugged in -- this isn't always the case with Desktop PC's so try it with the WIN +P key with the TV switched on of course and the HDMI cable plugged in.

If you DO get it to work don't forget to re-set the screen back to PC display before disconnecting or at the next boot if you don't have the TV plugged in you'll end up with a nice blank screen.

Cheers
jimbo

Hey there @jim1200, Welcome to the HP Support Forums! It is a great place to find the help you need, from other users, HP experts and other support personnel. I understand that you are having trouble with connecting a display to your computer and you are getting no signal. I am happy to help with this. Does your computer have a discrete graphics card installed? If so and if you are trying to use the two HDMI ports on the back of the motherboard of the computer instead of an HDMI port on that video card, then that is the issue. If a video card is installed, the integrated graphics adapter is disabled. Try using the HDMI port on the back of the video card itself. If this is not the case let me know, but if it does resolve your issue, please mark this post as a solution. Kudos would also be appreciated.

Test with a different monitor to verify the computer or monitor is faulty. Or test that monitor on a different computer.

typically, dual monitors is not done with VGA, or if so, is implemented using a 'Y' cable.

I bought a new HDMI cable yesterday, hooked it up to my laptop and TV and it worked just as expected. I unplugged the cable went away a few hours and when I came back to use it again and the TV was receiving no signal, Black screen with no sound. The laptop recognises the TV and says the connection is working properly but the TV shows nothing. The cable works between my Ipad and TV so it definitely looks like a setting issue on the laptop which is strange as I haven't changed anything manually between it working and then not. The TV is on the correct input and I have set the laptop to duplicate on a second screen. Tried a few things like changing the resolution and refresh rate but no luck.

Any ideas are appreciated. TIA

Sometimes this can be a "Handshaking" Issue. Try powering down the laptop and unplug the monitor. (never plug or un plug HDMI while hot) when you have the hdmi cable plugged in, plug power to monitor and restart, that may help.

Hello,

I just started having this problem on both of my laptops, Toshiba Satellite and an HP, and I have exactly the same problem on both of them. Both of them loose the signal as soon as windows starts loading so it has to do with windows 8 since I get a signal just before windows starts loading. I have tried to go to the display settings and on both of them will not detect my HDMI TV. I don't seem to be able to find a solution to this and it looks like there are quite a few people having the same problem but no solutions. Any ideas?

Eduardo
