Its good for the amount you pay. The power cord seems kinda cheap and flimsy. The part that plugs into the wall is a giant block and it gets loose in the socket which makes the monitor turn off and on sometimes but besides that its great. Good color quality and stuff. Apparently it has speakers built in but ive never used them.

This monitor relaced an expensive Dell monitor that failed after many years. It is the central unit in my 3-monitor office computer setup, and it has done a fine job.
