I am really excited to see 4K displays coming down in price. I have not had a traditional 'TV' in the house for nearly 8 years now (we have PCs with what was once considered 'large' 28" monitors), but am really interested in picking up UHD (not 4K) displays for both of the house computers in the next year or two. In all likelihood it will just run as UHD for desktop and movies, and 1080p for anything graphically intensive for the next few years as GPUs play catchup, but a 45-55" UHD TV would make a rather excellent monitor.
It will be curious to see if UHD displays will be easier to dumb down into a 'dumb display' mode rather than constantly trying to alter the input... also curious to see if win10 will play nicer with displays like TVs with more contrast than traditional monitors.
Oh... and to the author: It is Wireless ac, or 802.11ac, not a/c. 802.11a is no longer used anywhere, and 802.11c was never really 'a thing' in the consumer space.
