Vega 64 - black screen for two or three seconds during gaming

As per title.

I have a PowerColor Vega 64. Every now and then the screen goes black for a couple seconds, which drives me mad. The system doesn't hang like in other cases described in this forum, everything goes back to normal after a few seconds. It happens occasionally, let's say once or twice per hour, regardless of the game I'm playing.

My specs:

Vega 64

Z170 ASUS Sabertooth Mark 1

I7 6700K @ 4.6GHz

16GB DDR4 3200

600W Corsair PSU

Win10 64

IIyama GB276QSU 27" FreeSync

I game with FreeSync and Vsync enabled if that matters. Win10 is up to date, latest AMD driver installed too.

I have Vega64 too, Sapphire, and exactly the same problem. It is MOST annoying, when you play racing games

Maybe something wiht refresh rate? or active sync? I switched from DP to HDMI and it is better, but still it is happening. But only once per the game session, never twice or more ! it is very strange.

I have this issue  from very begginig.

Please help us !

OK I did these things, it helped me:

1) Turn freesync monitor and AMD card OFF

2) switch HDMI from 1.4 to 2.0

3) Turn both freesync ON

Now it is ok.
