As covered last week on Phoronix, with this next kernel AMD is enabling HDMI 2.1 support by default now that FreeSync, VRR, and ALLM support is included too.
I just spent all of last weekend trying to get my 4Kx144hz monitor with DP1.4 and HDMi2.1 working over HDMI to connect to my 7900xt which has DP2.1 and HDMI2.1.
For reference;
DP2.1>HDMI2.1>DP1.4
Best port my monitor has is HDMI2.1, and also DP1.4. Best port my card has is DP2.1, and also HDMI 2.1. It made no sense that HDMI2.1->HDMI2.1 had less resolution support than my previous DP2.1->DP1.4 setup did.
The monitor can do 4kx144 over DP1.4, but it requires DSC. When I switched over to HDMI to try and get 4kx144 without needing DSC (which HDMI2.1 can do), it just didn’t work, and the highest I could get was 4kx120. I chalked it up to somehow getting three different bad cables, a quirk of my Linux install (because my Linux mint install can only manage vrr on displayport if I unplug all but one monitor), or maybe a bad monitor port (this is a refurb model and not the only time I’ve had hardware issues with it).
Now, I’m wondering if I’ll be able to do 4kx144 over HDMI without dsc once this new update comes out. And also if I’ll be able to get vrr running with multiple monitors plugged in too.
Scuttlebutt on the internet says that the next big mint release will be out at the end of the year, and only support kernel version 7.0, whereas this new amd update is for kernel 7.4, also set for release sometime around the end of the year. I may end up distro hopping sometime in January if I can find an out of the box experience for HDMI2.1, without dsc, and with vrr support. Or at least, with vrr support. That shit is actually really good for the games I play.
I’ve used fedora in the past and enjoyed it. I’m just super basic and really love how cinnamon feels and looks. The other thing is I’m older now, and prefer to have a desktop that just works, or at least, keeps the same quirks it had last year, rather than having new quirks every update. I’ve been on the same install of mint for several years now because that.
For sure, this new update will likely be enough to get me to change my position on that if it works as I’m hoping it might.

If you wanna be on the latest kernel more quickly, you need to switch to a rolling release like Fedora or Arch. I personally recommended Fedora.

You can use Fedora with Cinnamon.
