Asrock Intel Arc A770 16gb - Can't enable HDR on W

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Good day everyone.
Got an Intel Arc A770 16gb from Asrock, the Phantom Gaming model. I'm using Windows 11 23H2 and I can't enable HDR using the DisplayPort cable on my LG Ultragear 32" (32GN600-B model).
The cable is the one that came with the monitor, and with it I could enable HDR and VRR with my previous GPU, a Radeon RX 6600, so the cable is not the problem.
Using HDMI I could enable HDR, but I lost the VRR capability.
I tried all the 3 DisplayPort connections from the GPU.
I removed the AMD driver using DDU in safe mode.
Driver is the latest one (4952) but tried the latest WHQL (4887) and got the same problem.
Does anyone knows what could be causing this problem?
Thanks in advance.

	Forgot to mention that I noticed that the memory clock is always at maximum (2186mhz) even when completely idle. Is that normal? Thanks!
