I'm on a Raspberry 5 on a 55" OLED 4K Smart TV S93C (2023). I'm having trouble getting 60Hz.

Kodi

Resolutions offered:

4096x2160p offers 23.09, 24.00, 29.09 or 30 Hz.
2560x1440p offers 60.00 Hz only.

Specs:

Raspberry pi 5
TV: 55" OLED 4K Smart TV S93C (2023)
Cable: Silkland Micro HDMI to HDMI 2.1 Kabel 1M (Reviews on Amazon specifically mention 4kp60

What I tried already:

Adding ``to /flash/config.txt:

hdmi_enable_4kp60
hdmi_group=1

I also tried the second HDMI port of the raspberry (Just loose CEC and same resolution on 30Hz)

happy to learn if you have any suggestions, thanks!

Apologies, I had to enable 'game mode' on the TV, now I can see 4kp60.

I'd recommend whitelisting the 3840x2160 modes as it's a more accurate match for broadcast media. The 4096x2160 modes can result in vertical black bars being shown.

I'm having a similar issue, no 60Hz, sometimes it briefly supports 60Hz, but my TV doesn't even have a "game mode" or anything like it.

I've not yet found what the cause of it might be though.

I have gotten 60Hz working when I use Raspberry Pi OS, so it's not the TV, cable or Pi itself that's the problem, it seems.

Do you have actual media in 4K60 formats? .. because outside of demo/test material it's a rare thing and 99/100 users trying to make 4K60 work (often with under-spec cables) have no real-world need for anything above 4K30.
