New monitor going blank

[Dave4u]

Hi all, 

While we are working from home I have the use of my work ultra wide, a Samsung 32" 75hz freesync monitor. 

 

On some games, cod ww2, bf5 I find that it randomly goes from normal gameplay to a black screen. When it returns to the game, around 2-10 seconds later the monitors osd shows my source icon again suggesting the signal has been lost. 

 

Still doing some testing but at the moment appears to not happen when set to 60hz I game gfx options. 

 

In PES2020, set to 60fps, it happens during a replay, not during standard gameplay. 

 

Anyone got any thoughts? Never happened with my own 24" dell (no freesync) using the same dp cable. 

 

Thanks

Disable 75hz in the display properties and see if it still does it. Is your normal monitor higher than 60hz or do you usually run it at 60hz?

My regular monitor is fairly old, 1920x1200 60hz 

 

Just did some testing with bf5. If I set res to 60hz, it's fine, go to 75hz immediate issue.
