Photo overview
The screen is matte black, there is very little refraction, albeit the photo does show a tiny bit due to our all-white studio and lighting. At 27 inches, it is a nice screen size alright, not too 'big' it feels right. However whether a 27" size warrant 3840x2160 pixels in relation to pixel density, well you decide.
So yes, whether or not you need Ultra HD at that resolution, is another discussion all by itself. The monitor allows the stand to be easily detached so you can fit a VESA-compatible mount of your choice with a 100mm x 100mm form factor.
Very stylish is the design, you can lower the position of the screen, the bezels are a rather thick though and the body of the monitor is also rather thick in depth. A tilt adjustment is offered by the stand so you can position it at a vertical and horizontal angle. You need to like the ROG styling, of course, that's not for everybody whilst others will love it.
The backside is far more impressive than the front side, design-wise, as mentioned you'll get HDMI 2.0 and the DisplayPort 1.4 connector. That is a proper looking monitor right there alright.
Once I aim the screen at a studio lamp you can see that it is a little reflective. In a massively lit room where you could see a bit of reflectivity, the coating is pretty good though. I've seen way worse on many monitors
The stand allows you to place the monitor in either portrait or landscape mode and, yes, portrait mode and photography do lead to some issues in a small space. So that's photography for you, in the real world this looks a-ok!
