Fully tested, fully functional. Plastic casing may have minor markings or other minor imperfections, but overall in good condition. Screen is in good condition but there may be visible imperfections when monitor is in use.
Good over all had one small place on screen butt can notice when powered on or in game. Would recommend to others shopping on a budget very good price.
It works perfect, it looks perfect, there is absolutely nothing I could find wrong with it, and the color looks correctly adjusted and perfect first time I plugged it in. It's sitting next to a brand spanking new Asus 4K monitor, and it holds its own side-by-side, not of course as sharp, but sharp enough to be a excellent match to the 4K.
This is one of four Dell monitors I own and use daily. All but one bought used. I have had great experiences with all my Dell monitors. Very satisfied with Ebay supplier's performance, pricing and quality of item supplied.
