Summary: I had this monitor for like 6 years and the power supply on it crapped out. I liked it because it provided a good amount of real estate was a nice contrast ratio (Length to Width) and very high resolution. Also the refresh rate is nice too. So I wanted to buy another one. This one that I bought was the B model and it seems to have just a hair more space but nice high resolution and refresh. Good monitor at a great price point.
