HDMI 2.1 support on Lunar Lake iGPU

Hi,

Does anyone know if Lunar Lake supports HDMI 2.1/will support it in the future? From what I’ve read Meteor Lake does, but 2.1 is a proprietary standard and there have been issues on Linux. I did try connecting a 4k 120hz display and it won’t get more than 60hz on HDMI.

For reference, I’m running Fedora 41 with KDE. I’m on the 6.12.9 kernel and mesa 24.3.3

It’s no more propritory that any other version of HDMI.

Apparently there are multiple HDMI 2.1 specs (?), and not all support 120hz at 4K. Wish they would publish this information on the website instead of having to contact support
