What are you using for displays these days?

I made a switch about 1 year ago now.   Moved from my Dell 7710 laptop 17" 1920x1080 with two 24" 1920x1200 monitors to this new configuration.  Dell 17" laptop 1920x1080 and one 49.5" 4K 3840x2160.  I have to say I like this very much.  I have my creo window take up just a little more than the top left quarter of the 4K screen. and I have plenty of room to open other items all around and on the laptop monitor.  Best part is I got this monitor for $329 at Walmart.
