Ive been having this problem the past few months when using my laptop with an external monitor the hdmi will recognise the monitor but wont display anything. The problem stopped for a while but has came back now.

the monitor sometimes turns on but will flicker on and off then turns completely black. the weird thing for me was it started to work fine and then it stopped working afterwards.

please do not tell me to try any of these solutions ive tried!!

things i've already tried:

tried pressing ctrl+windows+P

tried pressing ctrl+shift+b

complete reset of laptop

used DDU

tried a new hdmi cable

isnt external monitor because works with other source

updated all drivers

please help ive honestly tried everything and this is extremely frustrating
