ASUS PG43UQ 43" color problems

Hi
Could someone take a look at the screenshot and let me know if the monitor is malfunctioning or is there a setting I need to change?

Try running the tests here https://www.eizo.be/monitor-test/

Thanks for the reply, everything checks out ok on that site. When I play games I have no problems, it happens when watching videos,I have another 43-inch Acer monitor and I can drag between monitors and I dont have the color blotching in the Acer monitor. Something else that is really odd to me,, that the color blotching is only on the right half of the monitor. You can see the split better in this screenshot at the bottom. this color blotching likes to happen a lot with brown colors like the dirt.

Maybe try blowing away the Nvidia drivers with Display Driver Uninstaller (DDU) and reinstall the latest, does not appear like monitor issue to me.

Do you happen to have any codec packs installed, they might be source issue in playback ?

No , no codec packs. I guess I can try a fresh install of windows. You got me thinking too... I have my old PC still hooked up in the office, Im going to plug the monitor into my old PC and watch the same video again. Ill report back.
