If I am understanding your post correctly, you have multiple systems using this
same motherboard, Fatal1ty B450 Gaming-ITX/ac, and all of them have the same issue with
the HDMI output cutting out when used with another monitor connected to the DP
output?

If this is the case and you have already tried different cables, monitors and still
have the issue then I would recommend you open a support ticket with ASRock:

It looks like you have already tried everything I would suggest. Sorry I can't
be more helpful. ]]> Wed, 15 Apr 2026 17:32:54 +0000 https://forum.asrock.com/forum_posts.asp?TID=113491&PID=201209&title=b450-gamingitx-ac-multi-display-issue#201209 https://forum.asrock.com/forum_posts.asp?TID=113491&PID=201207&title=b450-gamingitx-ac-multi-display-issue#201207 Author: medic2003
