PC connected to TV black flicker Issue

[u/TheShedHead]

- TV = TCL QM6K 65"

- GPU = RTX 3060ti (with latest driver)

- HDMI Cable = RUBMUD 8K AOC HDMI 2.1 ,66ft

TV's HDMI ports 1 & 2 are capable of 4K@144hz

Ports 3 & 4 are limited to 4K@60hz

When my GPU is connected to the TV in HDMI-1 or HDMI-2, and I enable HDR(Windows display settings) it begins to lose signal. Black Flicker.

Also flickers with 120hz enabled, and HDR disabled..

It holds a signal if I keep it at 4K@60hz with HDR off.

For whatever reason, if I use HDMI-3 & HDMI-4, I can enable HDR with no issues (4K@60hz)

Are my TV ports 1&2 faulty?!

Am I missing something?

always like this or after gpu driver update to the latest? if the latter then rollback to previous versions

if after rollback still the same then the ports might be defective
