4K 120 FPS Over HDMI LG OLED TV Nvidia GPU

EDIT:I guess I should say this ,Thanks for the reply's and I know you are trying to help out and are correct. I made the video with a 2560x1440 resolution,said sharing for fun . I am wondering do you think I am trying to trick people into believing that this is actual 120Hz on a Nvidia GPU thru HDMI without a proper adaptor DP 1.4 to 2.1HDMI or proper GPU capable of such bandwidth. Also the adaptor can not do 120Hz HDR/G-sync

Added a couple screenshot one is 4K one is what is in video

4k 120 F over HDMI on LG TV OLED On Nvidia GPU

Sharing settings for those who would like to try out 4k 120 for fun,I just grabbed the settings of the net.No Nvidia Dynamic Super Resolution (DSR) needed

You will need a proper HDMI cable not sure if Variable Refresh Rate is working or just V-sync

1.No G-sync in game unless you turn off exclusive fullscreen. Then you would lose the 120 F and back to 60 F. No HDR 4K 120

2.Nvidia control panel enable G-sync and V-sync for the 120F

3.Setup custom resolution the same as in the video in the Nvidia control panel

4.Tested on Steam games exclusive fullscreen, may not work with XBOX Game Pass
