When I try to set the refresh rate to 120hz at 4k on CRU the refresh rate turns red and does not allow me to set it. How do I fix this?

EDID detailed resolutions are limited to 655.35 MHz pixel clock. The only way to add 3840x2160 @ 120 Hz is either in a TV resolutions data block in a CEA-861 extension block, or as a detailed resolution in a DisplayID data block.

I added it as both of those blocks but the option still does not appear in nvidia control panel or in display adapter properties

Do you have 48 Gbps HDMI 2.1 cable?

Do you have an RTX card? I think the adapter can use DSC to get 4K 120Hz. I don't know if it can do chroma sub sampling, etc.

What timing are you using to get 4K 120Hz (pixel clock)? 8bpc max for HBR3 without DSC is 1080 MHz but you probably have to go lower to allow headroom. If you have DSC then there should be no problem.

Yes I have a 48Gbps 2.1 cable and a RTX 2080 super. These are the last settings I tried but still no luck. [img][/img][img][/img] [img][/img][img][/img]

Where's the original extension block? You probably need it for DSC to work.

When I enable HDR, it automatically decreases the brightness of the monitor if I have a solid black background, or that's more important if I watch a movie and there's a night sky for example. I mean, it decreases the brightness when there's something dark on the whole screen. I guess HDR just turns off for that moment and then turns on again. So... Is this a bug or a feature? The monitor: 15.6" IPS 1920x1080 FHD 240hz, nVidia GeForce RTX 2060 6 GB.

That sounds more like dynamic contrast in the monitor.

I added the original block along with the display ID block and it worked. Thank you for the help.

Hi, when I use nvlddmkm patch and restart my computer. nividia drivers are removing themselves why ?

Something is blocking the driver. Riot Vanguard and FACEIT Anti-Cheat are common culprits.

before updating, I turned everything off and turned off autostart. and then the same removes the drivers for the graphics card after the restart pc

If anyone faces Black Screen of Death after overclocking their reso then try doing system restore by entering the menu [When the PC is booting Hold Shift and mash F8 and choose advanced options then System Restore or try using Safe Mode and reset the resolution,do the same to enter safe mode.
