Hello,
I am having an issue with my 4k, 60hz monitor where the color depth option in the Radeon is stuck to 6 bpc. An attempt to change it to 8, or 10 will not work, and it will just go back to 6, even though the monitor supports 10. I'm using a displayport 1.4 cable hooked up to my rx 5700 gpu. The monitor itself has a displayport 1.2 adapter. Origionally I thought it was a problem with a bottleneck in the monitor's displayport since if I lower the refresh rate down to 30hz in windows it will let me change the color depth up to 10 bpc. However, All the research I've seen online at least shows that displayport 1.2 should be able to handle 4k, 60hz with 10 bpc color depth. So I'm unsure why I'm having issues.
For Convenience here are the part numbers of my GPU, Display port, Adrenalin Edition Version, and monitor:
Any help is appreciated, thank you! I'm wondering if there is a known software issue, or if there is a bottleneck in one of the parts that I am not aware of.
