A:Answer Yes it is.
The only thing with this is, if you have a PS4 you will be locked at 60hz. Which means the monitor will set its self to 60hz. you will not be able to get the full 144hz out of it if your gaming on a ps4. Now if you have a Xbox one S you will get 120hz out of this monitor.
All in an all Yes you can play consoles on this monitor. I do. i play PS4 on this monitor and i love it. I play Apex, Warzone, Monster hunter world, The Division 2. They all look so amazing and rich in detail. I hope this helps.
