 Fix Vertical Lines on the Computer Screen 

A number of issues cause vertical lines on your computer screen,
ranging from software incompatibilities with the computer's drivers to hardware problems involving the magnetic field of the monitor.



Errors like:
"my screen has vertical lines causing the screen to look 3D without 3D glasses"

There are two general solutions for fixing the problem:

• Updating your video card drivers to the latest revision.
• Check field of the monitor

Step 1
Run Driver Easy on the computer to make sure the graphics card drivers are up-to-date. Old graphics drivers may not have the proper configuration to support the monitor, which may be remedied in the update.

Step 2
Right-click on the desktop, choose the "Screen Resolution" option, set the resolution drop menu to the setting that has the "(Recommended)" text next to it and click "OK."

Step 3
Disconnect both ends of the cable connecting the monitor to the computer.

Step 4
Straighten any bent pins you find in the connection cable. If any pins are missing or damaged the cable should be replaced.

Step 5
Check for any wear or bends on the cable. The cable might look fine on the outside, but the internal wiring could be damaged. Straighten the cable by pulling any bent sections apart with your hands.

Step 6
Reconnect the cable to both devices and check to see if the vertical lines are still present.

Step 7
Swap the cable with a second cable of the same connection type and check for the vertical lines. If the lines are gone, the first cable is bad.

Step 8
Connect the computer to another monitor using the second cable. If the monitor still showing the lines there is a problem with the graphics card.
Try using a different video connection port or type if the computer and monitor both support one. If the monitor still shows the line with a different port of the same type, there is likely a problem with the monitor connection.

Step 9
Connect the monitor to another computer using the second cable. If the monitor still shows the vertical lines, there is a problem with the monitor's connection port.

 How to Fix Vertical Lines on the Computer Screen 

Computer screens, like any component of a computer system, work or fail to work because of a series of possible factors: the input from the computer, the settings on the screen, and the performance of the screen itself. If you are seeing vertical lines on your screen, one of a few things might be happening. Sometimes the fix is simple and straightforward, and other times fixing vertical lines will require some troubleshooting.

Step 1
Power down the computer and unplug all peripherals. If you are using a laptop, take its battery out by flipping it upside down and sliding the battery release latch. Press and hold the power button for 15 or 20 seconds to clear all residual power from the system. Some of the computer’s power might have been transmitting to the monitor, causing it to short out. Reconnect everything and turn the system back on to see if the lines are gone.

Step 2
Unplug the monitor from the back of the computer and wait a few seconds until it displays a message “No signal.” If the no signal message also has vertical lines, you know the problem is in the monitor and not in your computer. Press the “Menu” button on the screen and then use the other buttons to browse for a “Factory Settings” mode. Select this mode to reset the monitor to its original settings. If the lines persist, the monitor may have been dropped or exposed to a magnet -- which can’t be fixed.

Step 3
Reconnect and turn the computer back on. Look for the lines at boot up: if you see lines before Windows loads, the problem is either with the video card, the video connection cable -- whether HDMI or VGA -- or the monitor itself. If the lines only appear in Windows, the problem is a Windows setting -- most likely the refresh rate. Right-click on the Desktop once Windows loads and choose “Screen Resolution.” Click “Advanced Settings,” “Monitor,” and then lower the refresh rate to see if the lines disappear.

Tips
If you recently installed a new program or driver update before the lines appeared, the problem could be caused by the new driver. Use “System Restore” -- a handy Windows application -- to restore the system settings to a date before you noticed the problem.
If you are using a laptop computer, the screen may have been damaged or jostled loose by being banged around, or by routine wear from opening and closing the lid. Try gently bending the corners of the screen to see if the lines change or disappear. If so, the lines are caused by physical strain on the screen. You can try disassembling the screen to remove some stress, though this will void your warranty.

 How to Fix Vertical Lines on Laptop / Television / Computer Screen 

Vertical lines appearing on LCD screen is very common. Whether the screen belongs to a laptop computer or desktop PC, mobile phone, or even a television, the fault is usually due to the ribbon cable and its connections.
A faulty ribbon cable can cause all sorts of havoc manifesting in bright vertical lines. Sometimes they can be coloured lines such as blue, green, grey, black, and red. The lines can appear thick or thin and on just one-half of the screen. Sometimes the fault will manifest as two vertical white lines. You can even get horizontal lines as well.
If you have lines appearing on the LCD screen, then the first simple thing to check is the seating of the ribbon cable that connects the display panel to the motherboard. Most of the time, the fault is with the poor connection made by the ribbon cable.

What causes lines?
One of the most common problems with ribbon cables is oxidation of the contacts. It can happen either on the ribbon cable contacts or on the socket contacts. Manufacturers often use a mix of gold and copper for the electrical contacts, however, if they have not used enough gold, then oxidation occurs over time. This results in a working television or laptop screen suddenly exhibiting lines.
The solution is of course very simple, one needs to clean the contacts with a high quality electrical contact cleaner. It is best to clean the socket and the ribbon cable contacts, which will solve the fault.

Cracked Ribbon Cable

One of the most common faults with laptops is that the ribbon cable connecting to the LCD panel cracks. It typically fails near the hinge area due to flexing in that region, and over time, some of the tracks on the plastic cable breaks. I have seen these types of faults on many laptops. It does not matter whether it is a Lenovo, IBM, Acer, Samsung, Toshiba, or even a MacBook Pro!

Dislodged Cable

It is also possible to have a dislodged cable, which typically occurs on mishandled laptops. The plastic clip that holds the ribbon cable is very small and delicate and if the laptop receives an impact, the ribbon cable can dislodge.
This type of fault can also occur on LCD televisions; however, it tends to be on new units, where the box has received an impact during transit from the factory.
In this situation, the repair can be easy, as the cable will simply require reseating. However, there is still the labour time to consider as it can take the best part of the day to gain access to the ribbon cable.

Troubleshooting
If the laptop has a socket that provides a VGA output, then the first thing to do is to hook up another good monitor to it to see if the picture is good. If the picture on another monitor is good, then you can be sure that the video chipset and the motherboard electronics are operating properly, and it is a connection issue.
I used this same method of troubleshooting to repair an LCD television recently. Modern televisions have a video out socket, and if you feed the signal from that to another monitor, you can check for the quality of the video display. If the external monitor does not show lines, then you know for sure that it is a connection issue. Hence, this method of troubleshooting works for some of the modern televisions as well.

Repairing a Laptop

When half of the vertical interlace is missing showing a picture that is broken up vertically, the display appears with vertical lines. This is usually due to a cracked ribbon cable.
Generally, for laptops a replacement cable is always required due to it breaking near the hinge. I had this Dell laptop and replacing the LCD ribbon cable solved the problem. I managed to buy a replacement from Dell for a modest price £6.00. The laptop was just outside the warranty period; however, they still shipped out the cable free of charge. This is the reason why people buy Dell. In my experience Dell tend to stand by their customers and products, and their prices for replacement parts are realistic and down to earth.
Replacing a laptop ribbon cable is simple, and the top-half of the laptop, and keyboard needs removing to gain access to the socket on the motherboard side. As you can see, it flexes near the hinge area and breaks where the ribbon cable wraps around the hinge.
