RGB full is usually used for PC monitors. Use YCbCr limited.
Ok. Thank you so much for your help

RGB Full also works. If RGB limited is default for my TV, should i be ok setting RGB Full? Or should i go with YCbCr limited/full ?

Maybe your TV does not like RGB @4K 24Hz. Try to test with hdmi_pixel_encoding=3 in config.txt.
That fixed it
Could this be a firmware issue with the TV?tvservice -m CEA still only lists 60Hz of the 2160p resolutions.
HDMI:EDID CEA mode (97) 3840x2160p @ 60 Hz with pixel clock 594 MHz has a score of 423131

Here is the output from edidparser. Also added as attachment.

Add this lines to config.txt:
Codehdmi_group=1 hdmi_mode=93Tried this on a different 4k TV, and there is no problem
The TV I am having this issue with is a Philips 43PUS6754 which should support these modes.Same thing still happens after I added these lines (and rebooted).
When I whitelist only 3840x2160p 50/60Hz + all 1920x1080p resolutions i am able to play 2160p/23.98Hz material with 1080p/23.98Hz output to TV, and 2160p/50Hz works fine with original resolution/refresh rate. But I cannot set resolution or play video with 2160p/30-24-23,98Hz natively.
My config.txt file now:
