Dell announces UltraSharp 4K displays — 1080p is now obsolete

My first computer came with a 13-inch CRT monitor. It was enormous, heavy, and flickered — probably the reason I wear glasses today. When flat-screen LCD monitors started becoming affordable, I bought one post haste. However, It was only this year that I achieved a 1080p display; the awesome 27-inch AOC e2752She. While I thought I was on the cutting-edge of technology, apparently, I am not.
