But if I connect through the KVM, the monitor flickers forever. I've tried to use CRU and lower the settings to 100 or 120, but can't get it to work with the KVM as well. Any advice on the settings that I should look out for? Thanks.

That's usually a signal quality problem. I don't know if a better cable might help or if there's some issue with the KVM. DisplayPort runs at fixed bit rates, so the refresh rate would need to be low enough to shift to a lower bit rate. If 144 Hz uses HBR3, going below 357 MHz pixel clock would shift down to HBR2. Keep in mind the color depth as well because 10 bpc would use more bandwidth than 8 bpc.

With the windows default settings I have eyestrain. I have verified that Windows reads 59.94hz. I have set CRU resolution standard lcd to 61hz and now the lcd is perfect. Could that be the problem? Is the 61hz value entered correct? Or is there a precise time to enter to get exact 60hz? If I put 60hz in CRU I have the same problem. Thanks to those who want to answer and especially ToastyX for the spectacular software.

What you're saying doesn't make sense. 61 vs. 59.94 Hz isn't going to make a difference with eyestrain, so there's some other factor.

ToastyX, thank you so much for your time. You were right. I set the "full" setting in the video Nvidia control panel in the color section and now the display is perfect. Thanks again for the quick reply.

Hello, I have a question that will hopefully ease my anxiety. Say I were to use the CRU application to modify the already present Windows 10 resolutions, and then I were to delete the CRU application. How can I reset all resolutions back to default (as shipped with the device) without the CRU application, and is this even possible? Thanks, and have a great day!

Uninstalling the monitor in Device Manager and rebooting will reset the monitor back to default. Using Display Driver Uninstaller (DDU) also resets all monitors.

Hi
I have a laptop with built-in HDR display but having trouble getting it to work in some games. HDR video is working, Auto HDR is working in some games (but doesnt look great... rather use SDR than bad HDR) but native HDR games I tested do not let me enable it, they think the display does not support it.

I have seen some other having this problem but no solution.
Im wondering if maybe you have some ideas what's causing this problem and/or maybe if CRU can be used to get the display to be recognised as HDR by the games somehow.

Thank you so much for your response. I have another question, though. If you were to create two or more resolutions (say 1920 by 1080) with different refresh rates using CRU, would they show up as duplicates when trying to change your resolution using Windows Display Settings (in the drop-down menu, you will see multiple 1920 by 1080 options) or will there be no duplicates but multiple resolutions would be available in Advanced Display Settings?

Is there a reason why we can't set the Min Luminance to 0 in the HDR Static Metadata section?

0 would mean unspecified, so leave it blank.

Windows will not list duplicate resolutions. Refresh rates are listed separately in the advanced display settings.
