Well it is possible!

After two failed attempts, finally a reasonable monitor!
Very cheap, enormous energy-saving, eye-friendly because flicker without PWM control and without IPS panel sparkle.
Black is black, white is white, colors are not exaggerated garish, and all very evenly and pleasant.
What more do you want?

I come from 27 '' iMac, and now wanted to Mac Mini and 27 'make' further Monitor.
Glossy displays were simply reflecting too crass, could the Mac better the ordered Dell S2740L went back again.
The next purchase, a test-flyer (Asus PB278Q) for significantly more money bugged with exaggerated colors, blurred fonts, and acting was just unpleasant to look at, probably because of the flickering PWM control. I certainly can not say that but.

So who is sensitive to modern LED monitors, here is the solution!
But be careful, GW2760HM the sister model has such a scheme, it must be the version "HS" !!!!
