I've been having issues with my monitor lately. Ever since I enabled HDR, the display looks really messed up when I first turn on my computer, lasting for about a minute. I can't tell if it's a monitor issue or something with my system, but it always seems to correct itself after a short while. This problem only started after I tried HDR, which my monitor is supposed to support. Turning HDR off fixes the issue, but I really want to use HDR without these problems. Any tips or ideas on what might be causing this?

Yeah, it’s almost definitely the cable. Just to give you an idea, here’s a quick rundown of the best cables for HDR:
1. DP 2.0 (~75Gbps)
2. HDMI 2.1 (~45Gbps)
3. DP 1.3/1.4 (~30Gbps)
4. DP 1.2 (~20Gbps)
5. HDMI 2.0 (~15Gbps)
Anything below that likely won't work well with HDR. For Standard HDR (like HDR10), these should handle it fine, but for dynamic HDR or higher resolutions, you'll definitely need one of the better cables.
It sounds like your cable might not be able to handle HDR properly. HDR requires a lot more bandwidth than regular output, so if you're using an older cable, that could be the cause of the problem. Just make sure your cable is up to standards.
Wait, do you really think I messed up my DisplayPort cable by trying to use HDR? My GPU and monitor are totally fine and haven’t given me any issues before.
