Game Master mode on TCL 50C735
Hi,
i just bought this TV only for PC Games:
https://www.displayspecifications.com/fr/model/9a852c21
So a quick sum, the TV is HDMI 2.1 and the panel is 4k@144Hz capable.
When connected to my computer (RTX3090), i only have 60Hz resolutions.
So i try CRU to get 4k@120hz with no luck. I only can get 1080p@120Hz.
I notice this in MonInfo on all 3 HDMI ports:
Code:
Timing characteristics
  Horizontal scan range.... 30-80kHz
  Vertical scan range...... 50-75Hz
  Video bandwidth.......... 600MHz
Video bandwidth should not be arround 1190MHz for 4k@144Hz?
After a call to TCL hotline, the guy told me that this resolution is only supported when a game console is detected (aka xbox series X or PS5) and then the TV switch "Game master" mode on (aka "game mode" for LG or Samsung).
I dont have next gen game console, so i can't test it.
I've attached moninfo result and dump of the TV EDID.
If someone can point me the right direction to get this TV at 4k@120Hz with a PC...
Thank you.

I don't see anything on TCL's site that says the 50C735 supports 4K @ 144 Hz, only the 55/65/75C735.

RE: Game Master mode on TCL 50C735
You can set 4K @ 120hz under Nvidia Control Panel -> Change Resolution -> Scroll down to PC -> 3840x2160 and select 120Hz.

I20Hz won't be available if you're using Ultra HD, HD, SD resolution. You have to scroll below to PC category.

Secondly, I'm using 55C735 and I can't use 144Hz at all in any resolution so I don't know if it's false marketing from TCL.
