Hello Tom
I bought this monitor about 2 weeks ago for almost exactly the same reasons. It is very good for image editing, especially because of its size. I've only played Ps4 on the screen about 3 times so far and it's brilliant. The screen is like a TV but with extremely fast response time, which is also great for gaming. The only downside I've noticed so far is that you need a big enough desk. If you sit too close to the screen, it's almost a bit too big. With my 27 inch screen I need a distance of about 60 cm and with the 32 about 80 cm so that I can see the whole screen.
Greetings
