I'm trying to connect my M3 Macbook Air to a Lenovo g34w-30 4K curved display, but after a recent issue where the display crashed, my Mac no longer detects it. I use an HDMI adapter to connect the two, but all I get is a dark screen, even though the monitor's speakers are detected. I've tried some troubleshooting steps, such as deleting the windowserver file from the Library, reinstalling Sequoia, and forcing the display detection, but nothing has worked. Does anyone have any ideas on how to fix this?

Have you checked if the monitor shows any video from other devices? Sometimes, the issue could be with the monitor itself rather than the Mac.
I only have my Macs to test with, but I did try connecting my M1 Macbook Air and it worked fine. The M3 Macbook Air works perfectly with other monitors, so it's just this 4K display that's causing trouble.
