Hello
Is this a laptop, or a desktop that connects to external monitor?
Let's check the most obvious -
Windows Settings > Accessibility > Color filters. Make sure it is OFF.
Windows Settings > Accessibility > Contrast Theme, make sure it is set to NONE
If these settings are correct but still showing B&W, let me know if you are using laptop or external monitor.
Also, can you share with me two screenshots please?
- Go to Device Manager > Display Adapters, I would like to see what's listed.
- Please type msinfo32.exe in the search on the taskbar and hit enter, then share a screenshot of the pop up.
Thanks!
