I am running a Framework 16 with the RX 7700S using Windows 11 version 10.0.22631 Build 22631 and the GPU is running firmware 24.8.1 (If I update this I lose all display, then I have to boot in safe mode and roll back the update but that’s a separate issue).
I am having an issue with an external display (an LG C2) where I can’t display 4K 120Hz and HDR at the same time. I think there is enough bandwidth and I am using a HDMI 2.1 cable in HDMI 1 on the TV. I have tried using the HDMI 2.1 to USB-C adapter out of the framework to come out of the back of the GPU to see if that helped but it has the same issue.
Enabling 120Hz disables HDR and when trying to turn HDR back on, it flickers then turns it back off again.
Am I having bandwidth issues or could it be Windows? I have checked the specs of the GPU and it should be possible I believe. Any ideas?
Thank you.
