Hi Richiewu,
Thank you for the posting.

We took the B450 Gaming-ITX, CPU 200GE, BIOS P3.40, Monitor ROG XG2GQU to test and our system can use HDR properly.

For this case, we would like to provide some suggestions for you to verify.
1. Clear CMOS by referring to the user manual page. 30.
User manual:£€https://download.asrock.com/Manual/Fatal1ty%20B450%20Gaming-ITXac.pdf
2. Keep BIOS setting default and only install CPU, PSU, Cooler, RAM, System disk to test.
3. Download the latest VGA driver from AMD website and install it to verify.
4. Reinstall a clean Win 10 20H2 OS to try.
5. Connect the monitor to onboard HDMI and DP port by turns to verify.
6. Flash the BIOS to P3.40 to try, please download the BIOS file from following link and use Instant Flash to update BIOS.

Thank you,

Best wishes,

I use 200GE on Windows 10 with Sony X95H TV which support HDR

But only show SDR in display setings, but I can enable HDR when I use J3455 itx

If not, which CPU support HDR on this board£]]> Fri, 12 Mar 2021 22:11:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=18340&PID=84604&title=dose-b450-gaming-itx-support-hdr#84604
