I'm confused. Can someone explain to me why I would want to buy this monitor, rather than, for example, the Seiki Digital SE50UY04 50-Inch 4K UHD 120Hz LED HDTV, which is available from Amazon for $700 too?<p>I already have a 27 inch IPS monitor with HD resolution, which was a nice upgrade to what I had before. The Seiki would give me 4K resolution with almost 4 times the display space. Am I missing something fundamental?
