Does the Verical line on the monitor also come when the monitor is unplugged from teh system. If yes the problem is with the monitor. If no the problem is with the video card. The computer maufacturer may have given you cds to run diagnostics on the card.
Eg on dell system , you need to press the f12 key 5 times after you turn the system on , to run the diags

Display vertical line


Turn off the monitor and disconnect it from the back of the pc. This way you will isolate the monitor from the PC. Now turn on the monitor, if you still see the vertical line then that means the screen is bad and you would need a new monitor.

If the monitor doesn't have the vertical line then that means your video card is the issue or if you have an integrated vga port on the back of the computer then the motherboard is bad and would need to be replaced.

Tip

Fix colored vertical lines on LCD display.


If your LCD monitor is displaying vertical lines whether they be green, blue,
black, red, yellow, etc then the following info is for you.
slasher_x_69.jpg
When it comes to vertical lines being displayed on the LCD screen it could mean two things; either the monitor itself is faulty or the video card is faulty. In the case that the video card is faulty it could be due to old/outdated/incorrect drivers being installed. For each of these options it's best to have your monitor's or laptop's user manual handy.

slasher_x_70.jpg
Adjusting the resolution
The first thing you'll need to try is adjusting the screen resolution. If you're
unsure on how to do this or want more info about it then see my tip here.
Try setting the resolution lower. If you're using a 4:3(square LCD panel) then your optimal resolutions are: 800x600, 1024x768, 1152x864, 1280x960, 1280x1024, 1400x1050, 1440x1024, 1600x1200. There are some other higher 4:3 resolutions but 4:3 ratio monitors that can support these resolutions are rare.
If you're using a 16:9 or 16:10(wide-screen LCD panel) then your optimal
resolutions are: 1024x640, 1152x720, 1280x720, 1280x720, 7280x800, 1366x768, 1440x900, 1600x900, 1680x1050, 1920x1080, 1920x1200, 2048x1152, 2048x1280, 2560x1440, 2560x1600. There are higher resolutions but they need faster graphics cards and larger LCD panels.

Start at a lower resolution and work your way up until the vertical lines appear. This will help you to find the most stable resolution for your setup. If they are still present even at a lower resolution then we will now try to adjust the refresh rate.

Changing the refresh rate
The next thing we're going to do is try a different refresh rate. Normally the
LCD panel manufacturer specifies the optimal refresh rate for the panel, this information should be printed on the packaging and displayed in the monitor's user manual. If you're unsure on how to do this or want more info about it then see my tip here.

If you've ever used a CRT monitor, you know that fine-tuning your refresh rate is essential. The refresh rate of a display is measured in Hertz (abbreviated Hz) and specifies the number of times per second that a display is illuminated. Setting the refresh rate to 60 Hz - a common default value - tells the monitor to redraw itself 60 times per second. For most people, that setting on a CRT monitor is too slow, resulting in an annoying flicker that can cause headaches, eyestrain, and fatigue. Bumping the refresh rate to a higher number can reduce that flicker, as long as the monitor itself can handle the faster rate. If you're using an LCD monitor then a safe refresh rate lies in the 60Hz-75Hz range. A greater refresh rate when it comes to LCD's means greater performance.

If changing the refresh rate doesn't affect the vertical lines then it may be time to update those video drivers. If you have a graphics card installed in your system then you can go to the various websites to get the latest drivers for them:

If you have an Nvidia card: http://www.nvidia.com/Download/index.aspx?lang=en-us
If you have a ATI/AMD Radeon card: http://support.amd.com/us/gpudownload/Pages/index.aspx

If you aren't using a graphics card and are using onboard graphics or have a laptop then you will need to go to the Pc's motherboard manufacturer's website or laptop manufacturer's download support website. A quick Google search can help you there.

Once you have downloaded and installed the appropriate drivers restart your system and see if the vertical lines are gone. If they are then well done!!! If not then we'll need to diagnose this problem on a physical level.

Try resetting the monitor to factory settings
Most monitors have an on-screen menu that you can use to reset the settings to default. You will have to follow the monitor's user manual procedure to do this.

Check the cabling (For Pc's not applicable to laptops)
Unplug the video cable between the computer and the monitor and check the ends for bent or broken pins. If any pins are damaged, replace the cable. Otherwise make sure the cable is securely connected at both ends namely the computer's graphics card or onboard graphics, and the monitor.

If the monitor has more than one type of connection available such as VGA, DVI, or HDMI, try a different type of connection.

Test out the monitor on another PC
If possible, connect the monitor to another computer. If the lines appear when the monitor is connected to the second computer, the monitor might be damaged or defective. If the lines disappear when the monitor is connected to another computer, connect the monitor to the original computer and check the step again where we updated the video drivers.

Test out another monitor on the system
If you can, try out another monitor on the PC. If there are no lines on the second monitor then it is indeed the first monitor that is faulty. If there are lines on the second monitor then review the section where we updated video drivers.

Where to from here?
If updating the drivers does not correct the problem, the graphics adapter might be damaged. Typically, video cards are damaged by too much heat caused by an accumulation of dust around fan areas. Cleaning the components inside the computer, especially the graphics card area, might correct this problem. You could also swop out the graphics card for one that you know works and see if the problem changes. Faulty or corrupt memory RAM modules can also cause vertical lines and interference; you'd better give these a clean. External intereference can be caused by magnets, check to see if there are maybe magnets nearby your PC (This only affects CRT monitors).

If the mouse cursor shows up fine when you put it on the vertical line, then it's you're video card. green lines are artifacts caused by VRAM or GPU overheating. Try using compressed air to clean your video card to the best of your ability. If by any chance you are using an integrated video solution, clean the northbridge heatsink.

If all these tweaks and troubleshooters fail to change the situation then it may be the fact that your monitor has reached the end of its life span. If it's still in warranty then have it sent back, if not then it may be time to upgrade.

Screen is white with black vertical lines upon booting up. I can't get beyond this screen.


The video card (built-in on the motherboard) maybe faulty or the LCD screen is faulty.
Connect an external monitor to the video port of your laptop, power up the monitor first then boot up your laptop. If the video card id OK then the laptop will automatically divert the video to the external monitor. Then the problem is a faulty LCD screen.
If the external monitor also displays black vertical lines then you have a faulty video card and since it is part of the motherboard it is impossible to fix.

Screen particially blacking out with vertical lines at bottom of my DELL laptop. at the bottom of laptop screen there are vertical lines @ 2" they are blue, dark gray,white, purple, light green lines....


Tryconnecting an external monitor to the laptop. You may have to select the videooutput to display on the external monitor by holding down the blue key and pressing the blue CRT/LCD (located on one of the keys, likeF8,F9, etc..). If the problem occurs on the external monitor with the batteryor AC power, then you have a problem with either the video card or motherboardin the laptop. If the problem does not happen using the external monitor thenyou laptop's LCD display is going bad.

Getting vertical line in acer monitor


Apparently it is a display hardware problem. Try another monitor with the same cable and video card. Then you should try another cable. Then another video card. If vertical line doesn't show in either case, then you should replace the appropriate device\cable. If it shows anyway, then bring your monitor to service center for diagnosis.

Vertical red line


Hello janicezavitz,
this is usually a driver problem: your computer and the video card does not work properly (or the wrong software driver is being used for the video card or maybe the refresh rate is out of range for the monitor). you can try to plug in a different monitor swap the video card into another pc or try a new one make sure the correct software driver is being used for the video card.


or try this:
1. Restart your PC and Boot into safe mode
2. right click on my computer.
3. Go to device manager
4. uninstall your video card (display adapter). Be sure to note the type of video card you have!!.
5. restart your PC again and now start up normally
4. adjust your desktop resolution (800x600 or 1024x768 etc) The lines should now go away .If not it might be your display or monitor problem.
5. and if the lines are gone, you should download and install the latest drivers

Green vertical line on LCD screen


Is this on a monitor or on a laptop LCD display?

Most of the time it is due to a hardware issue like a video card or the screen itself.

When does the line appear?
A. Is it there even with the monitor or laptop turned off?
B. Is it there during the OS logo / boot screen or does it appear after the OS loads?
C. If it is a monitor, with your system turned off go into the menu of the monitor by using the buttons on the front. Is the line there?

What you can do to try and fix it is.

1. Make sure you have all the latest drivers for your video card.
2. Change the resolution of the screen.
3. Change the frequency of the monitor.

If these do not fix your issue you may want to look at getting or borrowing a video card and replacing it if this system is a desktop. If this system is a laptop and the above does not fix the issue your best bet would be to put up with it or buy a new laptop to be honest.

Multiple lines on screen


Try connecting an external monitor to the your laptop and see if the vertical line is also present on the monitor. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor also displays the vertical line, then your problem is with either the video card or motherboard located inside your laptop.Not sure if the Compaq Presario has an external monitor plug, but if it does the above procedure can be applied to that one as well.

Vertical green line somthing like an artifact


Your Display cable (inside your monitor) needs to be replaced.

I would look on ebay to try and find the part and then take it to a local tech to replace it for you as I would not recommend anyone take apart a monitor (LCD OR CRT) if you had never done so before.

OR, Buy a new monitor.
