Has anyone worked with this OS(rock-5b_ubuntu_jammy_kde_b33.img)?

I downloaded this .img file (rock-5b_ubuntu_jammy_kde_b33.img) and flashed it on TF card.
Then i inserted TF card and made SBC power on.
But the display didn’t show anything.
(10inch 1280 X 720 and 16inch1920 X1080, both I can’t check those refresh rate…)

Does anyone else have a similar soituation?
If the person who has same situatishon, I would like to know how to fix it.

we tested this image, It works on 4K HDMI display screen, and the mipi display. do you try any other display.

Thanks a lot!
Oh, I don’t have 4K displays…
I will try to install the previous version.

4K is a example, I want to say that you can test other monitor.
