Question

Why does my PC monitor turn to inverted colours?

It's been doing this since I reformatted about 3 weeks ago, it's every 15-30 mins and sometimes it reverts itself back, and sometimes it requires me to change the HDMI source from HDMI 3 to HDMI 4, thus bringing back a normal display. It's definitely not the TV as it's never done this whilst on my PS4 or watching normal TV.

I have tried a different HDMI port
I have tried a new HDMI Cable
I have tried adjusting settings on the TV
I have tried adjusting settings in Catalyst control pannel (ATI 4850HD 1GB GFX Card)


Any help would be amazing, thanks.

I'm going with failing vid card. Why?

That video card looks to be from 2009 or prior. It's done well. Try another.

Update drivers...

Don't necessarily trash your card yet. Go to AMD and look for the latest driver update for your card. If not the latest go ahead and update it to the latest.

Also i recommend a laptop cleaning by opening case and air dusting the hardware free of any dust particles. A good way to speed up performance and solve minor silly unknown issues.

If all else fails before you exchange your card out try a different monitor source. And once you've tried those troubleshooting methods and it still doesn't cut it try an upgrade or replacement.

Good luck!
