[Asus tuf a17 2022 6800h 3070 W11] HDMI issues

vladNMP · May 5, 2022

hi,

I have an Asus A17 2022 6800h 3070 with windows 11, igpu, gpu, cpu and chipset drivers up2date, and a Dell S3220DGF with it's simple software

i confirm the monitor works as intended on a MSI ge73 8rf windows 10,

what happens: when I plug in the HDMI the image on laptop shrinks a bit (normal when you connect an external display), i can head a sound notification, the dell app shows that the monitor is connected via HDMI yet i receive just a blackscreen.

if i unplug it, i get again a sound notification, and "No HDMI 1 Cable The display will go into Power save mode in 4 minutes: if i plug it again back, image shrink on laptop, sound notification, and the display shows "No hdmi 1 signal from your device" , then "Entering power saver mode" then goes into blackscreen; this repeats over and over again.

when i turn on the laptop with monitor plugged in, i get some crazy artifacts (see picture, i dont have that much lightbleed haha its just the photo) on the monitor screen before entering Windows then black screen hell begins again.

is the HDMI connector dead?

my laptop comes with a MUX switch, tried both igpu on/off.

detect monitor function says "we didnt find other display"

attached a display manager picture, advanced monitor settings sees the display.

i'm out of ideas, please help.

thanks!
