I was able to successfully get the display connected to my PC with a full size AMD 5700 XT using a DP1.4(gpu) to USBC(monitor) cable from Amazon.
Now I am trying to run the display at 5k and use AMD’s integer scaling to output 1440p for gaming. I have tried setting the display settings resolution to 5k,4k, and 1440p. For some reason it says not supported. I assumed this should work because there are 4 pixels on 2880p for every 1 pixel on 1440p. I’ve done basic troubleshooting. Any ideas?
