Detailed description:Every second PC monitor I connect through HDMI flickers or turns black and reapears again after a second. I tried to update the drivers, change ever power settings to Maximum and reset windows and it still happens. I have two "graphics cards" - intel HD 620 and NVIDIA GeForce 940MX.

I wonder if there are any other S510UQ owners that faced the same issue.

It started about a year ago.

Appreciate your help.


  • An example of my screen when it turns black and reappear again.

    It also flickers once in a while (no pattern that I could recognize).

    It flickers more often when the CPU is working hard.

    The cable, pc and electricity are all fine. I checked this setup with two other newer ASUS laptops and they both where OK (no flickers whatsoever).

  • Hello ofridan22,

    Sorry for the inconvenience caused.

    Thank you.
