Asus GL552VW, with i5-6300HQ
GTX 960M, with NVIDIA driver 470.57
Ubuntu 21.04
My second HDMI monitor has blink screen every 30~60 seconds, and #136's solution works for me
I changed the refresh rate of screen from 60Hz(default) to 74.91Hz
After that, blink screen never happen again for now
I have the same problem on my laptop
