1920 x 1080 display, HDMI. The model is 2311x. Here is the top review on amazon:

"For the price, this monitor is a great value. HP list price is $250 (on HP website), but I got it on Amazon for $179 (price fluctuates from day to day). Highlights:

(1) The screen is indeed a matte finish. I dislike the more prevalent glossy screens, which reflect overhead lights. The bezel is a glossy black though. It can pick up stray reflections. I have no idea why glossy black is so fashionable in electronics these days. Well, I'm grateful at least that avocado isn't the color de jour.

(2) Text, still images, and video display sharply and with clean colors. At work, the IT dept recently bought 21" monitors from another brand. Text is jagged. Images and video are washed out.

(3) There is a full range of settings available controlled by four small switches at the bottom front right corner of the display. One switch brings up the main menu with 10 fields. The other three switches allow you to scroll up/down, left/right, and enter. It's a bit tedious, but you don't need to tweak all the settings. I mainly changed the brightness and contrast to suit my taste. There's a reset to factory settings selection in case you mess things up. The unit at work has horrible switches buried under the bezel that take a lot of pressure to activate.

(4) The inputs provided are VGA, DVI, and HDMI. Although this is a 1920 X 1080 display, it's still useful to have a VGA input. You can use it with computers with only VGA outputs and be HD ready when you upgrade your PC. Another reason I chose this unit is because of the HDMI input. My laptop has VGA and HDMI, but not DVI. Many HD monitors on the market have VGA and DVI. You then have to buy an HDMI - DVI adapter. VGA and DVI cables are supplied, but not HDMI. "
