Hey there! Sorry for bad english.
Got this acer s271hl, been working fine until few days ago when i cut the power then turned it on again.
It says no signal, ive tryed different hdmi-cables, different usb-c to hdmi converters.
Tryed usual PC since im using mac nowadays.
Been checking all over google and youtube, and it comes to me doing this manually via the screen. The problem is that the screen has power but says no signal, and I CANT use the extrabuttons on the screen wich are suppose to take me to videosettings but it wont.
Screen is in good shape and havent been used much at all, seen lots of people on google with same problem but nothing solved it.
PLEASE HELP ME!!!!
