So. Bought Samsung q80t, connected to it laptop with video card rtx 2060 in port tv hdmi 4. In the settings only 2560x1440hz mode. No 4k 120hz. Then I bought a new hdmi cable version 2.1. Again there is no 4k 120hz. Then I downloaded the utility cru resolution and could get 4k 120hz. Vrr with hdr 4k 120hz worked great. Then i connected to the laptop my old hdmi cable ver 1.4. 4k 120hz working great vrr with hdr works in all ports hdmi ( hdmi 1, hdmi 2, hdmi 3, hdmi 4) with my old cable. How can this be?
You need to have hdmi 2.1 on your graphics card. Only RTX 3000 series and Radeon 6000 series have it.
Yeah I was getting 120hz on Hdmi 3 as well on my 3070, I couldn't use HDMI 4 because it would flicker and cause issues because this model has issues with HDMI 2.1 at the moment.
But you will find it's only 4:4:2 when using HDMI port 3, you still get 120hz 4k though.
I didn't have to even setup a custom resolution or use CRU, it's just available in the PC list of resolutions listed.
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
I just bought a QLED 50Q80B 2022 TV coupled with an RTX 3070 but I can't get the 3840x2160 120HZ in NVIDIA Control Panel or Windows
I'm using a brand new HDMI 2.1 certified cable
Can you please help me how did you manage to make it work with CRU utility please ?
What settings did you use ?
