I purchased it refurbished originally and have used it for about 3 years, mostly for work. I've played some games on it including NBA 2K which is pretty fun because you can see the entire basketball court. The monitor works great. There are no dead pixels. I've since upgraded and kept the monitor safely in its original box.
