For gaming I would choose the HP as it has a lot less input lag, deeper blacks and no RTC overshoot compared to the U2711. The U2711 would be better for photographers because of the wide gamut CCFL back light and OSD.
Huh? the u2711 isn't backlit, it is CCFL edge lit. The u2711 can be prone to IPS glow/backlight bleed because of this. The HP ZR2740W actually uses LED backlightning which is better than what the u2711 uses - the HP as a result isn't prone to IPS glow or backlight bleeding. Luckily, Dell has excellent QA and the u2711s i've seen haven't had big backlight bleeding issues.
Both of these monitors basically look almost exactly identical -- the dell has more ports and OSD, though. The super aggressive AG coating kills the deal for me. I cannot stand it because I do a lot of text work, and any white background in a lit environment will look dusty or grainy on either of these screens. Its sad because they're near perfect otherwise.
