[SOLVED] Trouble setting 120hz with Nvidia on new C1 OLED

[SoTM]

Hi,
I just bought an LG C1 OLED. I primarily game and watch movies on this in my living room. I have a gaming
PC running an 2080 TI

In the NVIDIA control, there is no option under "Ultra HD, HD, SD" for 4k and 120hz. I can only select up to 60hz.

Under "PC" on resolution, I can select 4k and 120hz and it works. However, all games and movies have roughly 1.5 black
bars on the left and right. There is no way to get rid of these without manually stretching the image under TV settings, but
that causes problems with the desktop display when I go back to it.

Also, under the "PC resolution of 4k and 120hz", the taskbar is always present. I know I can set it to auto hide, but I hate that.

Any suggestions? Am I missing something here? I am beyond frustrated with this and I am about 1 second away from returning the
TV. Thanks.

The 2080Ti only has HDMI 2.0, for 4K 120Hz support you need a card with HDMI 2.1 which for NVidia was implemented with the 300 series.

Thanks. I was able to set to 120hz with 1080p under "ultra HD"

Why am I able to select 4k and 120 hz under PC? I had run AC valhalla on that, with AC valhalla setting at the same and it was claiming that I was getting 74 FPS. Although it did look crappy and more like 40FPS.

Thanks again.

See the table https://en.m.wikipedia.org/wiki/HDMI

Looks like you might get 4k 120Hz with reduced colour chroma 4:2:0 but full 4:4:4 is not supported. Last I read is you could not get 4K 120Hz on TV with anything under a 3000 series card.
