I am trying to adjust the Range Limits for my new 34inch monitor but am not able to. My monitor is semi off branded (Viotek GN34C) but does Freesync with a stock range of 80-100hz, I'd like to set that to closer to 40-100hz.
When I click Edit for the display properties screen I can edit the range limits but the Ok button is greyed out so I cannot save the settings, and my monitor driver name is off and has red text I'm assuming this is the culprit (image attached).
I'm able to run the monitor with Freesync enabled at 100hz and everything seems to work fine, just can't edit my hz range limits. Any advice is greatly appreciated!!
Thanks.

That looks like a partially corrupt or misprogrammed EDID. It's possible only the product ID is corrupt, which wouldn't affect any functionality. You can change the product ID to any 3-letter + 4-digit hex value you want. I think the default for that monitor is HKC0000. That should let you save.
