Hey Community!

i got a really strange behaviour with my Acer Predator Helios 300 (PH317-52-51M6) and a second display (BenQ PD2700U) connected via HDMI.

The disiplay randomly turns black for about a second. Sometimes just once, sometimes it turn black 10-20 times in a minute. ANd it really turns just black, it's still powered on (the white led doesnt disappears or turns orange; it keeps white). This behaviour really randomly occurs and doesn't depend on using a specific software. Currently it also happens while writing this issue and i only have opened the browser.

What I've done/tested so far
- Laptop Energy Options are turned to "balanced"; The options for turning off the monitor are set to "never"
- Updated the nvidia drivers (
- used different resolutions (behaviour occurs on 4k and fullhd) and frequences (50-60Hz)
- used the monitor on a different device (PC -> no Problems at all in 4k) and a second Laptop -> only fullhd resolution, but no flickering)
- tested another monitor (Full HD) with my acer laptop -> no problems/flickerung.

Unfortunatly i cant try the setup in windows 10 safe mode. 

Do you have any ideas, what else could cause this problem?

Thanks in advance and kind regards,

    Have you tried connect it to as other outer display? I would suggest contact the repair center if issue still happens.
