How to fix my Benq Monitor which is scrolling full screens of different colours.

Need a 12 volt test light to get those answers. Can walk you through all if you request live support for me.

This is all I could find. Hope it helps.

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

Check the data-cable between the computer and the monitor, and try a different cable.

Or, try connecting the monitor to a different computer, to see if the video-card in your computer is not working correctly.
If necessary, replace the video-card.

Colours on your monitor are produced by "mixing" the 3 "primary" colours: red/green/blue in various proportions.

Or, if part of the monitor that produces one of those 3 primary colours has stopped working, then the resulting "mix" will have too much RED/PINK. Fix/replace the monitor.

If you have a desktop computer, try connecting a different monitor, to see if your monitor is not producing all three "primary" colours (Red/Green/Blue), thus resulting in "mostly-green" colouring.

If you have a laptop-computer, trying connecting an external monitor, to see if you get the correct colours on the external monitor.

Please look here, you may have the same problems:

Please post back what you find.

Hook up a different known good working monitor to the computer. If the good monitor works then you know its the original monitor that is bad.

If the good monitor gives you the same problem then you know its the video card at that point that is bad.

Let me know if the original monitor that is giving you the problem is an old crt monitor or if its a newer LCD monitor?

On the monitor below the screen has these fine pink and green lines blinking across the screen all the time on my laptop. Can you tell me how to fix it or solve this problem?

Go to menu and try Recall all.
Also possible that panel is defective.

My Benq lcd monitor does the same thing.
