Hello, i have this weird line on my monitor, it started as a small line across the monitor but no it's that big and i think it gets bigger every now and then, does someone know what might cause the issue?

That type of artifact is usually caused by a an issue with the cable. Try rerouting it or using a different one to see if the issue persists. Also, try booting into your BIOS to see if it appears there as well. If it does we know it's not an issue with the OS.

• Turn your monitor off and on again. It seems like a basic fix, but it can often correct any screen glitches, such as horizontal lines.
• Restart your computer. A quick restart can fix a variety of tech issues and could get rid of any flickering lines on your screen.
• Try a different monitor. If possible, try connecting to a different monitor or screen. It can help you determine if the lines are caused by your computer’s screen or the computer itself.
• Check your monitor while it’s disconnected. Keep your monitor powered on, unplug it from your computer, and look for any flickering or lines on its screen while it’s disconnected. If you see any kind of distortion, this means that your monitor is damaged.
• Detach and reattach the keyboard. If you have a computer that uses a removable keyboard, remove it, wait a few seconds, and reattach it.
• Close and reopen your laptop. Close your laptop’s screen, wait a few seconds, and reopen it again slowly. Look to see when the lines begin to appear on the screen as you open the laptop. If the lines only occur at a certain angle, the cause is likely damaged wiring.
• Use your laptop on a hard surface. Soft surfaces such as on a blanket or tablecloth can cause overheating, resulting in screen flickering and lines.
• Install the latest operating system updates. Old software conflicting with newer hardware could cause the lines on your computer screen.
• Check the monitor connection. Ensure all of the cables are securely connected, and watch for any improvements in screen image quality while you’re inspecting the cables. If you notice the image improves or worsens while touching the connecting cable, it may need replacement.
• Disconnect the monitor. If you’re using an external monitor, disconnect it from your computer, wait several seconds, and reconnect it.
• Remove magnets and electronics. If you have other electronics or magnetic devices near your computer, screen, or the connecting cables, move them somewhere else as they may interfere with the connection and cause the lines.
• Clean your computer and monitor. Dust may be causing your computer and its monitor to overheat and create visual distortions.
• Change the screen resolution. Whether using a Windows or Mac computer, try changing its screen resolution.
• Calibrate your monitor. This process should only take a few minutes and can help optimize your monitor for use with your computer and its environment.
• Change your monitor’s refresh rate. Switching to another refresh rate setting can help with lines and screen flickering.
• Update your device drivers. Check for driver updates for profiles associated with your monitor and screen.
• Run a troubleshooter. Open Settings and select System > Troubleshoot > Other troubleshooters and run the Video Playback and Program Compatibility troubleshooters. If you get presented with any recommendations for other troubleshooters, run those too.
• Reset your monitor to its factory settings. If you’re using an external monitor or screen, use its built-in settings, not your computer’s settings, to reset it to its factory settings. You can usually access these settings via a physical Settings or Menu button on the computer monitor itself.

Hi HassanAhmed

Solution 1

We need to determine whether it is a hardware or software issue..  Turn off the computer.  Tap f2 ( f2 for laptop , del for desktop ) while turning on the computer.  It will go to bios.  Please stay on the bios screen for 30 mins.  If the display is looking good on bios then it is a software issue.  If the display is not looking good on the bios screen then it is a hardware issue.  

If it is a software issue try the following the steps.

Try windows x 

go to device manager 

expand display adapter

right click on display driver - uninstall 

Restart the computer 

It should work fine.. 

If it is still not working 

Uninstall the display adapter from device manager 

Don’t restart the computer. 

Go to support.acer.com 

chose your country 

type snid or chose your model 

go to drivers 

Install the display driver 

It should work fine.. 

Solution 2

It might be a cable issue..  Remove all the cables from monitor.  Press and hold the power button of monitor for 1 min.  Connect all the cables back. Try to turn on the monitor.  Connect the monitor to computer and check. If the cable is non removable please don't try to remove it. 

Please remove the cable between monitor and computer.   Try to connect it back and check.  If possible try to use an alternative cable and check.  

If the problem persists try to use an alternative power cable and display cable and check.  Try to bypass the surge protector and connect the monitor directly to power outlet.  Try to connect monitor on a different power outlet or surge protector and check.  

On the monitor – use the control buttons.  There will be an option to reset monitor settings to default.  Try to reset the monitor and check.  

To isolate the issue, try to use the same monitor to a different computer and check or Try to use an alternative monitor on this computer and check.
