Aug 19 2013 - The monitors that you see on this list are outdated as I have since split it into separate 27-inch and 30-inch lists to better distinguish the two sizes as well as take into account the increasing number of larger displays.
While 30-inch displays are very nice, they are also extremely expensive. Hannspree has made an extremely affordable but large display with the Hanns-G HZ281HPB. It features a 27.5-inch LCD panel that uses a 1920x1200 resolution with fast 5ms response time. There is a feature to speed the response time to 3ms but it isn't really advised to use it as it produces more lag between the computer and the screen even though it redraws the pixels faster. Connectors include an HDMI, DVI and VGA. There are two 2W speakers built into the panel. The stand only features tilt adjustments. Prices start at $300.
While the price tag ranging from $900 to $1100 may scare off many, the Dell UltraSharp U2711 is a spectacular display that manages to outperform many 30-inch screens. The 27-inch display uses IPS technology for some impressive color and a very high 2560x1440 resolution. Response times are slower at 6ms but it is still fast enough for dealing with video or even gaming. Those wanting to use it for graphics work will be happy with the wide color gamuts and color calibration for sRGB and AdobeRGB from the factory. Connectors are plentiful with DisplayPort, HDMI, Two DVI, VGA, composite and component. It also features a four port USB 2.0 hub and 7-in-1 card reader. The stand fully supports height, tilt and swivel adjustments.
Gaming is highly dependent upon fast response times to produce fast images without motion blurring. The ASUS VE276Q offers a very fast 2ms response time that is very important for gamers. It also is one of the few displays to offer DisplayPort which is key to anyone looking to use ATI's EyeFinity feature for multiple displays while gaming. The thin bezel helps make this a great display to use with this feature. The 27-inch display panel has a 1920x1080 resolution and also comes equipped with a light sensor to automatically dim the display when the gaming runs into the late night. Connectors include DisplayPort, HDMI, DVI and VGA. Also included are 3W stereo speakers. Priced around $325.
While HDTVs can double as computer displays thanks to their HDMI ports, some people may not have video cards that support this connector. Thankfully, there are some computer displays that also double as HDTVs. For those looking at a large screen, the LG M2762D-PM is a solid choice. It features a 27-inch panel with 1920x1080 resolution for full 1080p HD video support. Response times are quick at 5ms meaning that there shouldn't be blurring during fast motion. A built-in HDTV tuner lets it function as both display and TV. Connectors include two HDMI, DVI, VGA and composite. Also featured are a pair of Dolby SRS XT compatible stereo speakers. Prices around $350.
Dell's latest 30-inch display is great for anyone looking to do some serious graphics work. The display offers a color gamut that includes 99% of the AdobeRGB gamut and fully 100% of the sRGB. To make it even better, Dell calibrates the displays to these color gamuts straight from the factory along with a report of its performance. The 30-inch IPS technology panel features a 2560x1600 resolution with 7ms response times making it suitable for video work as well. Connectors are plentiful including two HDMI, DisplayPort, two DVI, VGA and component. Also includes is a 4 port USB 2.0 hub and 7-in-1 media card reader. The stand features full height, swivel and tilt but not pivot. Priced around $1500.
