I've had this 30" LG W3000H for a couple of years now and still can't find anything wrong with it. If you have the money, I suggest you go 30". The 2560x1600 resolution really is something else. Makes anti-aliasing quite unnecessary. And zooming out to 120 degrees FOV also looks great and increases your SA +billion percent
About spotting dots:
In old IL-2 the full resolution makes you blind, so I use 75% of the native (1920x1200), I can see everything further away than a squadmate with 24" screen.
In CloD the native resolution works good and I can spot the dots when they appear.
