Black screen when launching for the first time with 4K display

[h0m3]

Hello,

I have an issue when launching ChimeraOS for the first time on my Samsung 4K TV. After instalation on first boot I get the boot splash with my motherboard logo then a black screen. I cannot ctrl+alt+f3 and the system looks inresponsible. But if I boot the first time on a smaller resolution display, this time a 1360x768 display I get Chimera to boot normally and once its booted I can unplug and plug again into my 4K display and every subsequent boot will run fine at 4K@60 FPS.

My system is:
AMD Ryzer 5700X
32GB of RAM
Intel 660p 2TB
AMD Radeon RX7700XT (from Asrock)

[confess-a-bear]

I have this problem too :(

To the OP, I have AMD Radeon RX7700XT (from Asrock) also, and don't encounter your problem connecting the a Hisense 4K TV.
Did you install Chimera with it connected to the 4K?
And it may sound lame, but have you tried a different HDMI cord? (I found out an issue I had was using a 1.0 HDMI cord I had laying around from the Xbox 360 days of 2006)

Thanks and sorry for the delay. Already changed the cable, and the weird thing is that the system works fine after I boot using another display the first time.

I found something very interesting that can be a pointer, my TV support both 3840x2160 UHD and 4096x2160 DCI, and on this specific card I cannot put the TV on 3840x2160, only 4096x2160. My older RTX 3070 could run on both resolutions. I do think that there's some relationship between the problem and that "quirk".
