[SOLVED] help with 4k 60fps display via soundbar arc

[marlu123]

hello, this is my first post.
so here's my setup.
i have a windows 10, i7 gtx1080ti PC.
I want to game on my 40in 4k tv while listening audio tru my LG SK10y soundbar which has a dolby atmos feature.

i connected an Hdmi cable from my GPU to one of the soundbar hdmi in and video ouput to the 4k TV is connected via soundbar ARC hdmi out.

The audio seems fine but i am only getting 4k 30fps on the display. I would like it to be 60fps. what do I need to change in my setup?

Hi, Have you tested GPU to tv, instead of GPU to soundbar?

hi thanks for answering.
i have tried GPU to TV, i'm still getting 30hz on all resolutions, 4k, 2k and even 1080p 30hz on nvidia control panel. already tried custom resolutions at 60hz but tv gets black screen.

when connect from PS4 to TV, i'm getting 1080p 60hz.
GPU to TV, i'm getting 30hz on all resolutions.

Are you using the same cable for PS4 and GPU?
Can you test different graphics card, or the onboard graphics?

yes ps4 cable 1080p 60hz no problem.
have not tried the on board hdmi cables since my gpu is connected.

also tried 3 different hdmi cables.
the TV is on PC mode, but there's no setting for HDMI 2.0 or 1.4.
I'm thinking of a DP to Hdmi adaptor but maybe the result would be the same knowing that at 1080p i still get 30hz.
i just want to use my TV at 4k 60hz.

Here's a screenshoot of my gpu hdtv settings

Hi alexiou,
finally got to get it working
all i did was made a custom 4k reso,
then i tested til i got a stable hz at 59hz.
my setup now is gpu, soundbar, tv arc.
