White Vertical Line on Screen

Q: White Vertical Line on Screen

I was hoping someone could help me, I litterally just took my brand new HP All in One 21-3140 out of the box and the display as it was first starting up looked great and then it performed an update and now on the right hand side of my screen I have a white dotted line going down it. I have tried rebooting my computer and pulling the power cord out along with the connections for the wireless keyboard and mouse and cannot seem to get rid of it. Any help would be greatly appreciated. Thank you

Preferred Solution: White Vertical Line on Screen

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.)

A:Vertical white line on the laptop screen

Hey Patrizia,Welcome to the HP Forums!The first steps that you should attempt is to make sure that the vertical white lines do not appear in the BIOS. To do this I have included the steps below.1. Turn off your computer2. Make sure you have connected the power cable3. Turn on your notebook, as it is starting press the  F10 button repeatedlyOnce you are in the BIOS, if the lines are still present, it is likely a hardware failure. The next two steps may resolve the issue. The first one is to do a hard reset. I have included the document 'Performing a Hard Reset or Forced Reset'. The next and final step is to perform a BIOS update. I have included the information here for you 'Updating the BIOS'.Let me know if the issue does not appear in the BIOS.Hope this helps!

I have a Dell Inspiron 3537 model. It has been giving me a problem on and off. There is white vertical line which comes right in the middle of the screen. I used to press a little lightly on the screen and it used to disappear. But since morning it has been constantly there and troubling me a lot.
Request help asap and thanks a ton in advance.


The only way to permanently solve the problem is to replace the LCD -- if the system is under warranty, contact Dell and they'll do that for you. If it's not, the screen you depends upon whether it's a standard LCD (about $50-100) or a touchscreen (requires the complete assembly;  about $200).

Hi guys, this is my first post on one of these forums. I have 2 vertical white lines that go all the way down the display on the laptop. Had the laptop just over 12 months therefore is out of warranty. How can I fix this issue? Will HP be able to replace or repair this? Also is there an email address to contact HP customer support as I couldnt find one on the website. Thanks.

On my Dell Studio 1749 a vertical white line has appeared about 3 inches in from the left hand side.  It started off about 1mm wide but is gradually increasing in width and is now about 4mm wide.  There is no problem on an external monitor when connected.
Is this likely to be a fault with the panel or a chip problem?
Thank you.

A:Vertical white line appeared on display.

Hi  Ian,
This could be an issue with the LCD. To isolate the issue follow below steps:

Check if the vertical lines appear in BIOS screen (Restart the computer and tap F2 on Dell logo).
Also restart the computer and check the display in Safe mode (Restart the computer and press F8 on Dell logo and select Safe mode)
Run the diagnostics on the computer (Restart the computer by holding the” D” and power button and wait till the LCD test completes) and let me know the test result for LCD.

Awaiting your response!

Hello Guys,

I'm new here so pleae go east on me. Its my first post. I noticed yesterday that there is a very fine thin line on the left side of my desktop. In the screen shot you can barely make it out, but you will be able to once you see ot from the left corner of task bar. it does not appear when i open a browser or a folder or even start menu. It only shows on the desktop screen and is really annoying. I tried disabling some odd services and restarted the computer as well, but still no luck. A little help will be appreciated.

P.S: Screen shot is below.

Hi there
If you are using an external TV type of monitor go into the menu of the Monitor -- usually via a remote controller etc. Somewhere in the Video / picture setups you should see an option like auto adjust picture / size or something like that -- then the image should fit the screen perfectly.

(Assuming of course that you have set the resolution (in the PC settings) of the monitor to one it can handle).

Hey all. I have a 5 yr. old HP Pavilion dv6t 3200 CTO Laptop. I have had a 1/4 " white vertical line on the right side on my display for awhile now. It is there all the time, even in safe mode, even when I run computer error scan.( Black Screen with white line still) The pointer will disappear under the white line when trying to scroll making this difficult. I have used HDMI cable to my TV and the display on it shows no white line. I then assume that it is either the screen or the display cable. I would have to open it up either way, but was wondering if there is a way to figure out which is the culprit ? Or just go for a new screen, just do not want to open it and replace screen to find out cable is bad. Any ideas ? Thanks

A:Vertical white line right side of Hp dv6t 3200 laptop display

I believe the HP Pavilion dv6t 3200 has integrated graphics, meaning the graphics are soldered to the motherboard.
It is possible that it is the screen, but personally i think it could be the graphics chip. You mentioned that when you connect to an external display the "white line" is no longer visible.

You refer to the cable possibly being the problem are you referring to the HDMI cable or the cable that connects the screen to the motherboard?

If you are talking about the cable that connects the screen to the motherboard, the cable is soldered to the screen therefore if it is the cable a new screen will be needed. Can you take a picture of the line you are seeing please as this will help me diagnose the problem.

If there is a warranty or Guarantee in place for the item then dont try to fix it, you can void any warranty, take it back again and again until you get a working system or until you get your money back.

The screen's cable is most propably damaged. Just to confirm that the fault is in the monitor, post a screenshot from a time where the line appears... Replacing the cable will not be the simplest job, I assume, but will be quite an easy fix...

Have you tried putting the removed drive back in?

It looks like a video card problem (hardware) to me - but it shouldn't be that because you're able to use the USB Startup Repair functions (am I right in this assumption?). That means (to me) that it's likely to be a video driver problem (?).

Can you attempt to boot into Safe Mode? If so, what happens?

I have a 2 year old Gateway laptop which, I understand, was actually made by Acer under license.

All of a sudden a vertical line appears midway in the screen display. Sometimes it is a red line, sometimes a white line.

Does anyone have any idea why this occurs? Is this a sign of the "kiss of death" for my laptop display, to follow? Does this mean the "end is near" for the screen?

I use Windows 7 Home Premium SP1.

I started using a new 17" 4:3 monitor. Afterwards, two white vertical lines (borders ?) appear on the two sides of the black content area of a few program windows when maximized.

For instance (IrfanView, whole screen):

Is that normal?

The old monitor was also 17" and 4:3, but there were not those two lines.

Even if it's normal, I'd rather not see them. Can they be hidden?

I have tried "Personalize > Windows Color > Advanced appearance settings > select Border Padding from under Item > change size from 5 to 0". But that seems irrelevant.

A:Two white vertical lines on screen unseen before

It looks like the edges of the IrfanView window to me (i.e. I see them when I run IrfanView).

As far as I'm aware you can only get rid of them by going to "Full screen" view.

A:Black screen/vertical line freeze!

Well, yes, heat kills hardware. However, if that projector had been so hot, your laptop would have at least restarted, if not turned off, in order to save itself from potential damage from the heat.
There are some programs for monitoring your laptop temperatures, you can use them to check if the problem occurs because of overheating (SpeedFan and Core Temp).

If the problem has something to do with your drivers and the restore point is before you have updated for example your Display Driver, then you could first try running in safe mode and see if the problem still occurs. If no, restore your system, it won't delete any files, it will only return your registry and drivers to earlier state.

That you are out of warranty shouldn't stop you from taking your laptop for diagnostics. You will have to have money of course, but at least they will fix the problem ; )

I'm back again; this time with an issue on my desktop. I always set the monitor to power off after sitting idle for a few hours. This morning when I tried to use it; the monitor flashed white then went to a black screen with progressively brighter vertical colored lines in different groups across the screen. We powered it off; disconnected the monitor connector and reconnected - still get a white screen on start up then the black screen with color lines that grow brighter and brighter as time goes on. I have onboard video with this machine - praying its not that. I've read other posts here about the lines; OR the white screen but not both. Any ideas friends?

Helo all,

I having a problem with my pc when start the pc....white screen appear then few colors line came out....

izzit my graphic card broken?that is a build in graphic card, can it plug in a new external graphic card then the pc can be running again?

pls give me some suggestion!!


A:PC start with white screen v with few line color

Check the connection from the monitor to the PC. Try another monitor. If no change in the problem, trying a new graphics card is a reasonable thing to do. More information on your system would be needed before suggesting what kind of card would work.

I'm sorry for the lack of any technical terms used to describe this but I'm a complete novice with computers.

I was watching a video when some warning messages popped up saying something like harmful stuffs trying to access your computer, then it restarted. Now it starts up, goes to the motherboard thing, goes past that then hits a black screen with a little white line flashing in the top left corner.

I've tried to use F8 to enter the safe mode start up but when I press F8 it comes up with



I tried the SATA option twice, first time the white line vanished so it was just a black screen and then it restarted. Second time it just went back to the screen with the white flashing line.

Any help in sorting this out would be greatly appreciated.

Hello all, 
I have a problem very similar to this thread:
On boot the bios posts fine, but after that it immediately goes to a black screen with a white line. I am unable to enter safe mode, and it never moves past this screen. I thought it was a hardware issue, so I cloned the drive onto a completely new drive and it has the same exact issue. So now I have to suspect something is wrong with windows itself. 
Prior to this, the computer was working fine, then it shut itself down and on immediate boot up this issue appeared. System restore does not work from the windows 7 DVD, and I've tried startup repair numerous times, as well as chkdsk and sfc scans.

I have posted the FRST log for reference.
Thank you.

I need help..

I bought a 15 inch NEC lcd about a month ago and have been using it without any problems. Just this morning a red vertical line appeared about 7/8ths of an inch from the left. I have the latest driver with windows xp. The line doesn't seem to actually be on the desktop and it overlaps everything. I've also tried resetting the monitor configurations. Does anyone have any idea of how to get rid of the red line?


A:NEC vertical line

IT seems that Part of your LCD monitor is not functioning Correctly. Under Normal Circumstances your monitor maybe do a POST ( power on self Test ) and the line is Initated that way. You may want to try Booting into Safe Mode and DOS prompt to see if the line goes away. If its does Its mostlikely a driver issue. If not then its the monitor and you should return it. Also try hooking up another monitor to it just to see if you have the same prob. JFYI you have Display adapters and Monitor Drivers make sure you have both up to date.

I'm not sure exactly what that is. Do you mean there's a line there when its turned on only, or is it always there, even when shut off?

If its there when it's shut off then it sounds like a pressure crack on the screen to me. Hopefully its not that. I had a nasty on one my Sidekick 2 once. x.x

But even if it is, if its a not interfering with the picture try to disregard it. That's all I can say.

Note: Symptom is similar to one described in earlier note by SJackman.
There are small vertical line grids around desktop icons and the cursor on my display. Also, video shown on Microsoft Media player shows larger (longer and thicker) vertical lines over the images. (The video otherwise plays normally.) The lines do not appear on my desktop background or around the little icons on the Windows taskbar. As I type this note, I can see small vertical grids below my cursor pointer, but not elsewhere on the screen. Other than the vertical lines, my PC's functions seem normal.

Alright, I have a Toshiba notebook and the other day a vertical, thin, purple line appeared on the the right hand side of my display. I didn't drop my notebook or damage it in any way, no over clocking of any sort ether. It doesn't show on screen shot and when hooked up to an external monitor it works like a charm. I would like to know if the problem is fixable because my warranty is void. I am surprised this has happened because the laptop is only about a year and a half old. Thank you for your assistance.

A:Vertical Purple Line

That Purple Line is a dead or stuck pixel it could have been your Graphics Card but since it worked alright in a External Monitor it indicates the LCD Screen is faulty, this means you need to replace the LCD Screen. I'm not quite sure how to take them off or fix them back on but someone on here maybe able to help a bit better with that.

You could try looking on Ebay for your Toshiba Laptop Model, they sell laptops that may have 1 part not working (they will indicate what is not working) but will be a cheap option for your LCD Screen as well as other spare parts for your laptop compared to buying the Screen on its own here is an example -

Could be a failing display or a short in the ribbon cable connecting the display to the main board.
but if it disappears when you press on the plastic bezel around the display it probably is the display itself going out or got damaged.

A:green vertical line on monitor

Make sure that the cable is connected properly on the back of the monitor and the video card. Then try to go to the system BIOS of the PC to see if the green line is apparent. If that is the case the problem is not the video driver. Then try to run the monitor self test to see if the green line will show up. Look for instructions on your manual. If the green line is showing up on the self-test then you have a monitor issue and it needs to be replaced otherwise it is a video card problem and needs to be replaced.

A:Red Vertical Line Disappears When Pressed Then Re-...

The problem is something called a column driver. There is a connection to every column of pixels on your screen. If you have a wxga screen, there are 1280 of them. The connection is made by a strip of tape with contacts, that is held against the back of the panel by the adhesive between the contacts. Sometimes, the tape works its way loose due to age or vibration. It can be strained through incorrect routing of cables, etc during assembly or repair. It can also come loose if the screen is hit or strained. The "fix" is to replace the screen. If it is under warranty, I suggest calling Lenovo.

I recently bought a new HannS.G 22Inch widescreen TFT monitor and it displays a 1 pixel width vertical line of varying colours from top to bottom, which overprints the entire display, however it only shows up in the operating system, i.e.not in the bios at startup. The line is on the right hand side and does disappear and reappear randomly, but not with a restart. I have used it on two computers with the same effect.

Any ideas would be much appreciated


A:Vertical Line on Monitor display?

Well the first thing is that since it's new it's under warranty so you'll probably be sending or taking it back. Since it shows the same problem on two machines I'd bet on it.

The only other thing I can suggest is to make sure you're running it in it's native resolution and refresh rate.

Hello everyone!

A couple days ago, my LCD monitor has been showing a pink vertical line towards the right side of the screen. This is rather annoying. Whenever this is present and I turn off the monitor & turn it back on, it fails to find the video source and goes to sleep mode. I attached a picture of my issue to this thread.

This pink line doesn't appear immediately. It usually shows up after about 5-15 minutes of computer use, and very rarely disappears on its own. Any help would be appreciated.

A:Vertical Pink Line on LCD Monitor

Hook another computer up to it to test.

If same pink line shows up, then you know the LCD is failing.

If the pink line doesn't show up, then you know it's an issue with your GPU (either drivers, or hardware failure).

It extends into my lower menu bar and was just halfway up my screen yesterday. Today it is bolder and goes almost completely the entire way up. I have tried rebooting and virus scans with no luck.

If you can it would be useful to connect the netbook to an external monitor. If it is no longer present (and I think it won't be but , then the problem is with the laptop screen. It is possible that it could also be the connection from the netbook MB to the screen.

I started seeing a very thin (1 or 2 pixels) vertical red line directly in the center of the Flash Player window about 6 weeks ago and I have been unable to fix it.  The red line does not appear when I am watching videos in VLC Media Player, and it does not occur in all Flash Player videos, but it does appear in most of them.  I rolled my driver back from 16.300.2311.0 to 16.150.2401.1002 and it was still occurring,  So I reinstalled the current version of the driver and chipset.  I'm using the Radeon Crimson software, AMD Radeon R7 Graphics, on a Windows 10 64 bit OS, with an AMD A10-7850K  processor.  Can someone please provide me with the steps to get rid of this vertical line?  Thanks very much.

Yesterday suddenly my laptops monitor turned pink with white vertical lines on it. I tried these things to solve:1. Restart System2. Memory Check3. Video Driver Re-install4. Troubleshooting5.  Pulled out the battery and kept my laptop turned off for a while6. Disabling both GPUs (Intel HD Graphics 4600 + AMD Radeon HD 8750m) But no luck....! The width of the white sripes keeps changing to wider-thinner. I'm using the latest BIOS:  01.31 Rev.AAnd Latest GPU Drivers I'm confused if it's connection problem or GPU problem! I'm badly in need of a working solution
