Hi, I have issues with my Acer E5-575G were on external monitor (only) blink/flick like 3 times per minute, each time goes black by 1-2 secs...

after a lot of research I believe can be because is a bug on driver of Intel HD 620 or HDMI max resolution is at limit (monitor is 2560x1440@60hz).

I tried so far:

  • change hdmi cables
  • tried VGA cable which max res. was 1920x1080 (which is so bad!)
  • fully unistalled drivers, restarted and installed lastest driver on Acer website, Nvidia webstie and Intel website.
  • disable video driver in safe mode and restar to verify is problem still (and still)
  • connect another monitor by hdmi to discard monitor or cable but my other monitor was at 1920x1080 and works fine
  • QHD monitor with lower resolution works fine (1920x1080)
  • I disable the power enhacement in Intel configuration (on battery and plugged)
  • I changed to consistent performance on Nvidia configuration panel

and still blinking, I noticed that if I use chrome, firefox or thunderbird at full screen is more probably I get this flickering.

please help.
