No doubt there are better and sleeker monitors out there, but I saw the prices. This one is fantastic and more than does the job for me. Probably getting another one too.

This monitor is greatly overlooked. You can't beat the price I got it at (92). The picture is fantastic. I set my expectations low, but I would buy another (and will in the near future).

Good product, Good price, and quick delivery

A great entry level monitor. The only downside to this monitor is that its base is static and cannot be tilted which is a minor inconvenience considering its price and display quality.

Very good. Very anti glare screen. Good brightness. Free sync monitor for so cheap is brilliant
