Summary: (+) Resolution (+) Very contrast picture (beats my MacBook Air's IPS) (+) My previous HP monitor had a glitch when switching sources (there was no way to switch to laptop without disconnecting/shutting down the computer) – but okay with this one (+/-) Minimalistic controls and total absence of any menus (I like it, but someone might not) (-) There are rumored troubles with power supply... we'll see... still okay after 5 months (-) No FullHD support.
Summary: I use my PC mostly for video games. I debated upgrading my old monitor to a 120mhz monitor or a 2560 x 1440 monitor and ultimately choose this monitor. I'm a medium-level gamer, so I didn't think 120mhz would really matter for my performance and I wanted something that looked noticeably better. Wow. This monitor makes games look spectacular. The additional detail is very impressive. I am very pleased with this purchase.
2013 Review: Newer units as good as Dell U2713HM (AG coating fixed!)
8 January 2013
Summary: This monitor was released late 2011, but at some point in 2012 there was a subtle revision in the anti glare (AG) coating. (search "ZR2740w v2" for a Nov 2012 review which discusses this revision). Some speculate manufacture dates, next to the serial # on the pull out service panel on the left side) in 2012 correspond to the newer units, but this does not seem to be verified.
Great quality and value. HP Support responded promptly for the issue I had.

Summary: I have been using this for about six months. I have another high resolution monitor, DELL U3100. My impression is this display is the best choice for most of users that need advanced displays with high res graphic capability from the perspectives of both quality and return on cost. Calibration of color space is in my view not an issue as long as you use Windows OS as the driver works flawlessly and does what it has to do.
Summary: Excellent picture quality; very good colors & contrast, huge brightness range. Very even backlighting with no bleedthrough. Calibrated settings pretty close to out of the box default uncalibrated settings (without the monitor driver .icm file, see below). 0 pixel defects. Excellent stand, or easy VESA mounting with snap-in plate. Very good price for a high quality IPS display this large.
Summary: Hello All, The Zotac Geforce GT 440 card works great. Purchased Zotac before HP display per the cards specifications. Works great using Displayport for ZR2740w and HDMI to HP2311x (2nd Display). Used Zotac drivers. Running Windows8 Metro on Dell XPS 8300 I7, 8Gig. Software Office Suite, Solidworks (CADD program) PowerDVD11 and windows media center. Zotac card available here at Amazon (where I purchased). Hope this helps.
Summary: I changed my old 24" Dell 2405FPW (owned for almost 5 years) for the HP ZR2740w and couldn't be more pleased. I did try the ViewSonic VP2765-LED AMVA panel, with has a great image and brightness, but the 1920x1080 resolution disappointed (after years with the Dell's 1920x1200 I got spoiled). Finally opted for the HP ZR2740w with 2560 x 1440 resolution, IPS pixels and LED backlighting. Only one word: spectacular.
Summary: My video card is an older ATI 4850 so after reading the reviews saying that even newer and higher end ATI cards wouldn't drive the monitor, I was worried. Before the monitor arrived I made sure that I had the latest drivers and on installation the monitor immediately woke up in 2560 X 1440. I use a dual link DVI cable; if you use DVI, make sure the cable is dual link.
