If one cares at all about text sharpness+clarity and the clarity and vibrancy of white colours at all, they should avoid the U2711 like the plague since it uses an extremely grainy matte coating. All 1200p+ matte IPS panels use the same coating. There is a reason the new Dell U2713 is going to be glossy 
This image shows how much the anti-glare coating degrades the clarity of pixels up close. For reference the 27Q LED-P is a glossy IPS panel and the X275, XB24, S24A350T and FP241W are A-MVA panels with semi-glossy coating which is the lighest matte coating. Most of the other displays are IPS panels which use the same coating as the U2711, which is why they look just as blurry. The ACD will look just as clear as the 27Q LED-P
Considerthe Samsung S27A850D, is uses a PLS panel (Samsung's version of IPS), semi-glossy coating=superior colours & text, almost no grain and it is sRGB=more natural colours for games and movies.
Both the Samsung & Dell have over 1 frame of input lag, delay sensitive users should get an ACD or dual-link dvi only Korean 1440p display.
1200$ buys a Samsung S27B970D which also uses glass like the ACD.
