RTX 4080 supports 4K160Hz on ktc m27p20 pro?

Post by BOLNICHKA399 » 19 Nov 2023, 23:25

I have an RTX 4080 video card and recently bought a KTC m27p20 pro monitor, which according to its characteristics supports 4k160Hz, I connect via hdmi 2.1 with the included cable, i.e. The connectors on the video card and the monitor are HDMI 2.1, but the best I got was 4k144Hz at 8 and 10 bits, even if I lower the resolution to fullhd, I still don’t get higher than 144Hz. KTC technical support claims that ALL video cards from NVIDIA do not support frequencies above 144Hz and that this is not a monitor problem, is this true or is KTC not telling us something?
I forgot to say something important, to try to run 160Hz I turned off g-sync in the monitor itself, and also turned off MPRT, local shading and auto HDR, but this still did not allow me to go above 144Hz

I am not much of an expert but stating that "NVIDIA do not support frequencies above 144Hz" is simply wrong.

if I am not mistaken HDMI 2.1 supports ONLY up to 144Hz@4K.

you need to switch to a DisplayPort cable , for each generation and its specs you can check out this link :

your link says that hdmi 2.0 and 2.1 support frequencies up to 165Hz
