Hi, maybe anyone can help or give advice thanks in advance. I have monitor Samsung 32" LS32BG750NPXXU G75NB 3840x2160 VA Mini-LED 165Hz Odyssey. In windows I getting full 4k resolution but in uefi max is 1024x786 on any port hdmi and displayport. Asrock uefi supports 1080p tested on different displays working fine. Its samsung firmware hardware limitation or something else...

That's a limitation of your motherboard. There's nothing wrong with the Samsung.

It might depend on how the UEFI reads the monitor's EDID.

and on hdmi 2.1 refuses enter uefi display just loops no signal... Sad
