Fantastic monitor
First off, I use this tv as a computer monitor; via HDMI I operate it at full 4k resolution (2160p) where it provides a bright vivid flawless display. The 55" size is deal for windows or streamed movies, displaying windows icons at an adequate size to be seen and used easily from 4 feet away for presentations or desk distances for working with side by side spreadsheets and wordprocessing or desktop publishing with one or 2 full sized support applications also on screen all at once. Using a google chromecast at 1080p also works flawlessly with the USB port providing sufficient power for the chromecast device. For game playing, it is simply unmatched.
