Can I Play 4K Games On A TV That Only Has 4K 50Hz?

I did find out that if I do HDMI instead of auto-detect, I can change all the settings to the way it should be with 50hz, 24hz, and 4k checked, but then when I try to change the resolution, it says it can't be done. Going in to the 4K TV details menu then
says my TV doesn't support 4k at all.

When i put auto-detect, in video mode the console don´t allow me to check any boxes (only the YCC 4:2:2), even doesn't hear the sound and in 4K TV Details all appear in red. when i override in HDMI, the sound is activated, and in 4K TV Details all the option
about 4K are yellow telling about the setting of the TV is not doesn't allow 4K and recommend put to connection in Auto-detect and in video mode the console allow me to check 50Hz, 24 Hz, 3D (the TV does n´t have 3D), YCC 4:2:2 and 4K, but the only option
allow me to put in check are 50Hz, 24Hz and YCC 4:2:2.

In the TV all HDMI ULTRA HD Deep Color are activated.

Hello, I am actually having the same issue with the same TV model LG 65UB9500. I was told that my TV is able to do 4K @ 50Hz but that option is also grayed out on my Xbox One S. Without that option I unable to see youtube videos and Netflix @4K. I read above
that i have to plug it into HDMI 1 in order to get that feature but if i am not mistaken that model only has one HDMI port that does 4K and that is HDMI 3. Can someone help out?

no console can manage 4k games but it can play 4k movies i just upgraded to a 4k tv it game with a 4k copy of spiderman played fine in xbox one

I don't believe the XBOX One S supports 30Hz at 3840X2160. My 4k doesn't support 60Hz but does support 50Hz, 30Hz, and 24Hz and I can't get anything on the XBOX One to work in 4k, including setting the TV Resolution. YouTube will not offer the option to
play in 4k and Media Player provides a green screen when playing a 4k MP4. There is no 30Hz option that I see in the Advanced Video Settings.
