For anyone contemplating buying a standard ratio 4k monitor vs a widescreen
one for gaming I have both and for what it's worth this is superior. The
immersion is great and the UI scales properly, whereas with 4k the UI in both
Windows and in games is often poorly scaled at anything below 30" and difficult
to read without upscaling it, which brings its own problems. The colour is
excellent with deep blacks, as you'd expect from an IPS display and the 100hz
refresh overclock works a charm and gives noticeably smoother motion plus G-Sync
works well. The only negative is the fiddly OSD controls but once setup
there's no need to touch them again.
