If you have a desk that would be very small in terms of viewing size if it's three or four feet away. Ideally you want to be sitting about the same distance (eyes to screen) as the monitor diagonal (for 16:9 monitor ratio).
Unfortunately, unless there are some which are not on PCPP, and that's entirely possible because there is a lot out there they don't have listed in terms of hardware, I don't see any monitors at all that are over 27" in size, 144hz, 1ms, with G-sync, regardless of what resolution. 27" is the largest I see with all those features, so if the monitor is going to be wall mounted and too far away to see with a 24 or 27" unit, one or more of those specifications is going to have to disappear.
This unit has all of those features, except no G-sync. In the event 27" is not large enough.
