Intel Arc A770 & TV Problems

Multimedia and gaming pc: Connected Intel Arc A770 LE to my TV via HDMI 2.1 port but facing multiple issues.

Running latest driver.

1. Stuck on 1080p 60hz because any resolution above this setting makes the GPU run at 40w, at 1080p 60 it is about 24w at idle. I have ASPM enabled the mobo is a asus B760-I with i5 13400. TV is a TCL C845 with native resolution of 3840x2160. Intel states low power mode at 4k@60 for 1 display but does not seem to work.

2. Windows 11 reports only 8 bit color mode in advanced display, the TV supports 12 bit, and I have not figured out how to manually change color mode on this GPU. Windows HDR mode is turned on.

3. Colors look terrible watching Netflix, looking for color tune guides. The brightness also looks lower than usual compared to built-in android tv. Maybe the 8-bit color mode?

I have tried older drivers, changing HDMI ports on TV and different cables, but getting nowhere.
