I have a 5700XT and an R2 kit. I'm trying to get 4k60 working with a single DP cable but don't seem to be able to do it. Any ideas? Thanks!

Actually maybe I was mistaken. I somehow got it into 4k60 mode, and it didn't like that.
Once I went back to 2DP connections 4k120 I'm back in business

Glad its working out for you. Do you have any flickering / dropout issues with 5700XT?

Most rev2 kits shipped only with 4k120/1080p240/720p360/960p480 modes, while most rev1 kits had 4k120/4k60/1080p240/720p360/960p480 . For 4k60 on rev2, need to change edid or use a software override from a single-input mode.

You should be able to leave both DP cables plugged in and use the monitor's mode switching to switch. The secondary input is hotplug-removed when in a single input mode, so it should be no different than physically unplugging the DP cable.

No flickering that I've noticed.

I think my problem was that there was strain on one of the DP cables causing misalignment. I had to replug the cables and then manually override the monitor setting from 60Hz to 120Hz, then it worked.

However, now I have the "zisworks.com" framerate overlay stuck on somehow :)
