Summary: I've been using one of these for years and wanted 2 of them. Unfortunately it's no longer available new so I bought one via eBay. These are great flat panel monitors for serious graphics use (photography and such) with 8-bit color rather than the 6-bit that is commonly found on cheaper monitors (look for that specification if you need better color).
Summary: Love these monitors. This is my 4th one for Quad Display. They are "OK" for gaming, but if you have good eyes can really notice ghosting. I however use them for professional / office applications. Multi-Tasking at its finest. Picture quality is amazing. Text is sharp and crystal clear.
Summary: Good value for a used monitor. Some complained about blurring in videos, but with the newest drivers, I had no problem in running it on Windows XP, SP3. I tied it on two PC's with a video card, and one with an on-board video chipset.
Summary: I already had 2 of these, and added a third to my 4 monitor setup. The screen space and image clarity is great! 21" for around $100.00. My 1st one I have used for around 4 years - no dead pixels, just clear viewing. Not a big gamer - so superfast response is not an issue for me, I use the setup for heavy multitasked work. 3 of these for under $500 total cost is a GREAT way to spend those 8-10 hour days.
