This is a PLANAR PX2710MW 27" computer monitor. I've had it for about 3 years now, although it was only used for one of those years. You can find all the technical specifications at the following Newegg listing:

　　The item comes without packaging, and I'm throwing in the cables I used to work with it:

　　- one VGA-to-VGA cable, that came with the monitor;

　　- one DVI-to-HDMI cable, which I purchased to connect my computer's HDMI to the monitor's DVI;

　　- one audio cable, useful for plugging your computer's sound port into the monitor's speakers.
