I just needed a replacement monitor for daily desk use and wasn't interested in gaming, etc. so this fit my needs beautifully. The color is great and the picture is crisp. It was a breeze to install. Great, everyday monitor and super size for home office desks where you won't need a theatre sized monitor.

Inexpensive, high quality, no frills. Perfect for home office where you are using for work tasks. For my setup I ditched the stand for vesa mount so I didn’t want to pay for a model with an adjustable stand that I wouldn’t need.
