4k@120Hz

[userYkxYelnnFz]

I have the new Q80T 65" 2020 model. I have my computer hooked up to hdmi 4. I have game mode on with game mode enhance setting on when in 4k. For some reason I can not find 120Hz. Max is 60Hz. My GPU is a AMD 5700 xt which is capable of the 4k@120Hz. Am I missing something? The hdmi cable is cable of the 4k@120Hz as well. I can set resolution to 1440 and get 120Hz no problem. I really would like to be at 4k@120Hz for games. Please if anyone knows what I need to do give a detailed step by step instructions on what to do to get this setting to work. Thank you in advance.

Starting on page 131 of the user manual you can see all supported resolutions.

Did you get it to work? If yes, how?

[userYkxYelnnFz]

I guess this TV does not do 4k@120Hz. Running 2560x1440@120Hz Rez

Samsung site says it does.

Thats what I thought. I will have to contact Samsung Monday and see what i am missing. I have played with all kinds of settings and can't figure it out.

Hey my dude. I got my 3090 a couple of days ago and I have a Samsung 80T 65inch. I bought a Belkin Ultra HD High Speed HDMI Cable for $100 at JB. Connected 3090 to 80T VIA HDMI PORT 4 - Took a minute to gain signal. Went on my pc (Windows 10) - Display Settings - Clicked on the display - HDR ON - Display Resolution 4096 x 2160 or 3840 x 2160 - Advanced Display Settings - Refesh Rate 120.000 Hz. Then (Went to my Samsung 80T Settings) Turned on Game Mode. Works like a charm. Here is the HDMI I used as a link - https://www.jbhifi.com.au/products/belkin-ultra-hd-high-speed-hdmi-cable-2m
