I also use a 40" 4K TV. The vast majority of what I do on my computers is text-based, which means that after the text is easily readable, I don't get any real gain from increasing the pixel density of the same shapes, but I get a lot of gain from having more text and types of textual things on the screen at once (as the article author apparently does, as well). Until recently, I used a 40" 4K monitor. For whatever reason, TVs handle input switching much, much more smoothly than monitors do: If I have two machines hooked up to different inputs of a monitor, and reboot the one I'm working on, the monitor will often spontaneously choose to show me the other input. A TV in the same situation will happily show "no signal" and stay where you told it to stay. I've only tried two brands of monitor (Planar and Philips), admittedly, but they behave identically in ignoring the manually-set input if some other input seems more interesting. :/ I had been using a Philips 40" 4K monitor for a couple years, and the frustration with input switching drove me to the same Spectre TV from the article, which is frankly worse in every picture-quality-related metric than the Philips, but doesn't instantly switch inputs when signal is interrupted, or blank and reblank the screen 2-12 times when it hasn't been on for a while. Well, that went a bit off track.
