If anybody is looking at upgrading their monitor to a larger, 4K unit, this may be a good deal for you. I was using 2 of these and switched to a larger one. I am selling a Philips Brilliance 28" 288P6 4K monitor for $450. Half of their original retail price and this one is in like new condition. I still have the retail box. It was purchased new 3 years ago and has been used 2 years. Nothing wrong with it. For more info on this monitor, have a look here:
