[9070XT] no signal on TCL TV.

[Leon-Swains]

GPU: 9070XT
TV: TCL qm751g
OS: Bazzite (bazzite-deck)

I created a bazzite image with the custom kernel. After booting, I plugged the HDMI cable in, but received a black screen with no indication of a connection. I have attached a dmesg log below.

In case it matters, #6 is also with a TCL TV albeit a different one. Is yours Roku like mine or Google TV?

[Leon-Swains]

Mine is a google TV.

Would you mind retrying on the latest code? I pushed some changes to the FRL rate picking and retraining logic

i also have a TCL tv with no signal ( unless i run the the hdmi diagnosis and repair on the tv, but then its only 60hz but i get an image)
my model is a C8K (qm8k) on google tv with latest firmware.
is there a way to patch this in with cachy kernel manager as 6.19 kernels don't have VRR with my tv, apparently it will be fixed with 6.19.4. i think that could be part of the problem possibly, so if possible i'd like to be able to try and patch it in to the cachy LTS kernel by adding a local patch. is this possibe ? if so could you link me to the patch i'd use to build it with cachy kernel builder.
thanks :)

Patches are generated here: https://github.com/mkopec/linux/actions . For 6.19.3, you want the one from the stable branch: https://github.com/mkopec/linux/actions/runs/22373904768.

Applying this patch in cachyos kernel manager requires removing the cachyos base patch as per #2 (comment)

[S1NN3R86]

6.19 doesn't have vrr on my tv. 6.19.4 is apparently going to fix it. So I'm using the cachy lts version which is 6.18 which works fine. So which patch would I get for that kernel? Sorry to be a pain

[mkopec]

The stable one, hopefully it will apply cleanly. If not, my v6.19.3 patches already have integrated the latest VRR patches from @Lawstorant, so VRR should work

[Leon-Swains]

Tomasz had mentioned that he was already working on DSC, will that eventually get merged into this repo?

[mkopec]

Yes, we will eventually try to implement DSC as well

[S1NN3R86]

So i added the patch to a cachyos 6.19.3 build and I still have no vrr, I originally also had no image but I restarted the tv and I did manage to get an image. But no vrr and HDR looked noticeably worse. How do I go about getting information to you. Like a log or something like that ? This is all new to me but If It can help solve this I'm happy to figure out how to do it with some guidance

[S1NN3R86]

not 100% sure what i'm doing, so here's a boot log and dmesg if that helps at all

this is with the latest stable patch

[Leon-Swains]

I also tried the new hdmi_frl_stable code, and still wont get any picture.

I don't think it likes our TV's lol. My ugreen dp to hdmi adapter also doesn't play well with Linux. It works but it flickers on and off a lot so it's not really usable. Really hoping they can solve this hdmi issue 🙏
