I have three monitors, including a drawing tablet, and I'm using all available ports—two HDMI and one DP. My MB HDMI screen began showing strange flickering with occasional red lights, so I rearranged the cables in a bit of a game. Now that one port isn't working at all. I can still switch cables whenever I want to draw, but I don’t want to constantly adjust. Updated: I checked my display settings and everything seems fine now. I’ll keep watching for any flickering, but I’m not sure what’s causing it.
It seems the system is interpreting two monitors differently. When you switch to "monitor 2," it behaves unexpectedly, while "monitor 1" functions properly. It looks like everything might be working correctly overall.
