MacBook Air M1 external display stop working

[luanodev]

So, I've recently bought a m1 air and a usb-c hub, everything was working fine, 3 usb ports + hdmi (Philips 27" 4k @ 60hz), then I took a nap and let my mac turned on, when I got back from the nap, the display was not waking up and it suddenly stopped working, reconnecting, restarting, turning it off then turning back on, nothing worked. I tested the display on a Dell laptop with Windows 10 and it worked, I tried another display on the usb hub (a LG ultrawide) and it worked fine, only my Philips 4K 27" won't work, macOS also blinks when I connect the 4k monitor but nothing happens after that, not even show as a connected display on mac settings.

Any tips?

Need more informations about types of ports/cables/connections.

MBA -> USB-C hub -> which port of Philips monitor?
Dell -> USB-C hub? Direct connection? Which port?
MBA -> USB-C hub -> which port of LG monitor?

Hey!

Philips monitor: 276E8VJSB/57 connected through USB-C Hub HDMI port into MBA (it was working correctly)
LG Monitor: LG29WK600 connected through USB-C Hub HDMI port into MBA (it is working correctly)
The Dell was tested with direct hdmi connection.

The strange part is, it was working and now when I try to connect it into the MBA it blinks, move some windows and get back to original place, and no clues about the monitor being connected
