XG270HU goes black momentarily, then comes back

I purchased this monitor on Black Friday, plugged my PS4 into it, and had been playing on it for a week or so with no problems.  Then over the last two days, it's gone black for a second or two, and come right back on.  It doesn't display the source or say anything when it does.

 

It's connected to the PS4 using HDMI, but the cable that I had before I got the monitor, so I don't know what version it is.  Thanks.

check AC power cable too if it's well plugged.
