Green Lines on Monitor’s Screen

Green Lines on Monitor's Screen

Computer screens, like any part of a computer system, work or stop working to work because of a series of possible elements: the input from the computer system, the settings on the screen, and the efficiency of the screen itself. If you are seeing vertical lines on your screen, one of a couple of things might be taking place. Sometimes the repair is basic and simple, and other times fixing vertical lines will need some troubleshooting.

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

2. Disconnect the monitor from the back of the computer system and wait a few seconds up until it displays a message “No signal.” If the no signal message likewise has vertical lines, you understand the problem is in the screen and not in your computer. Press the “Menu” button on the screen and then use the other buttons to search for a “Factory Settings” mode. Select this mode to reset the monitor to its initial settings. If the lines persist, the display might have been dropped or exposed to a magnet– which can’t be fixed.

3. Reconnect and turn the computer system back on. Try to find the lines at boot up: if you see lines prior to Windows loads, the problem is either with the video card, the video connection cable television– whether HDMI or VGA– or the screen itself. If the lines just appear in Windows, the problem is a Windows setting– probably the refresh rate. Right-click on the Desktop once Windows loads and select “Screen Resolution.” Click “Advanced Settings,” “Monitor,” and then lower the refresh rate to see if the lines disappear.


If you just recently set up a new program or driver update before the lines appeared, the issue might be triggered by the brand-new driver. Use “System Restore”– a handy Windows application– to bring back the system settings to a date prior to you discovered the issue.
If you are utilizing a laptop computer, the screen might have been harmed or scrambled loose by being banged around, or by routine wear from opening and closing the cover. Attempt gently bending the corners of the screen to see if the lines alter or vanish. If so, the lines are triggered by physical strain on the screen. You can attempt disassembling the screen to get rid of some stress, though this will void your service warranty. For basic guidelines, see Resources.
