Totally worth it, but with many caveats.<p>I&#x27;m on my 4th (!) 4k monitor, and think I have found the sweet spot - it&#x27;s a 48 inch curved 4K Samsung JS9000 TV that supports 4k @ 60hz with 4:4:4 chroma over HDMI 2.0.<p>At that size the pixel density is identical to a 24&quot; 1080p monitor and the slight curve means it fills your field of vision with significantly less distortion at the edges.<p>Unfortunately the stand isn&#x27;t adjustable, so I replaced it with a set of adjustable &#x27;feet&#x27; off Amazon that bolt to the wall-mounting holes. The screen sits about a centimeter off my desk - just enough to run keyboard &amp; mouse cables under, while keeping both the top and bottom of the screen at comfortable viewing distances.<p>The overall result is _glorious_. I have so much room I can just drag windows over to whichever part of the screen I feel like staring at, while having tons of room at the top for widgets and music players and such. I can run games in windowed mode alongside web browsers and everything&#x27;s readable and playable. I can have pages and pages of code spread out everywhere and it&#x27;s all marvelously usable.<p>In comparison, my other 4k experiments -<p>1. Seiki SE39UY04 39&quot; - Terrrrible lag, bad color, 30 hz only. The 30 hz is not itself the killer (30 hz on the JS9000 is only mildly irritating), it&#x27;s the 100+ millisecond delay that makes it infuritating. Sold it for $100 after trying and failing to adapt.<p>2. Samsung 55&quot; UN55HU8550 - Great except for the lack of 4:4:4 chroma, and 55 inches is just -too- big to use as a monitor - especially without the curve. I still use this one as my main living room monitor &amp; TV.<p>3. LG 40UB8000 - Almost good enough. No 4:4:4 chroma, slightly buggy firmware, too much color distortion at the edges when used at monitor distances. Pixel density is about the same as a 27&quot; 2560x1440 monitor, but in practice you&#x27;ll be squinting as it needs to be placed farther back on your desk in order for the sides of the screen to be usable.<p>Samsung does make a cheaper 48&quot; 4k screen (the JU6700) which I believe supports 4k@60, 4:4:4 chroma - it would probably be just as good as the JS9000 for most purposes, with only slightly reduced color quality and a few less bells and whistles.
