Here's a chart which shows the ideal viewing distance for various resolutions, based on the smallest detail the human eye can discern at 20/20 vision.<p><a href="http://cdn.avsforum.com/4/4c/600x376px-LL-4cd4431b_200ppdengleski.png" rel="nofollow">http://cdn.avsforum.com/4/4c/600x376px-LL-4cd4431b_200ppdeng...</a><p>This monitor is pretty close to retina level DPI based on the typical viewing distance, but i guess a 24inch 4K would be even better.
> Web browsers can be a problem. <i>You may want to choose Internet Explorer</i> rather than Chrome, since Microsoft has clearly done more work to support high-PPI configs. However, note that IE ditches the ClearType sub-pixel antialiasing scheme and snap-to-grid GDI font rendering in favor of simple greyscale antialiasing. As a result, the effective text resolution with IE at high PPIs isn't a huge leap from other browsers with ClearType on conventional displays. [emphasis mine]<p>Umm.. I know Firefox is not fashionable these days but ignoring it completely seems bit odd, especially if both Chrome and IE produce suboptimal results.<p>Also can't you these days force compatibility bitmap-scaling for applications like Fraps that apparently do not work correctly with HiDPI? Sure it is one extra step that ideally shouldn't be necessary, but it is not like you need to live with broken UIs.
My Chromebook Pixel has spoiled me. A 28" 4K monitor isn't sharp enough. Dell has a 24" that yields 180 ppi. I'd be interested to see that in person, but it probably still isn't sharp enough comparatively.
Good to see the price of big high resolution screens coming down, after so many stagnant years.<p>> The one thing that may freeze you from pulling the trigger right now on the PB287Q is, oddly enough for the monitor market, the promise of better things coming soon.<p>Any guesses about how the market will progress in the next year or two?
I have an old 30" 2560x1600, bought for £1200 6 years ago - good enough for my uses (coding). Would like to get a second similar screen, when they are cheap. At the moment I see e.g. 27" 2560x1440 for £420 [1] - would buy it today, except maybe I can get something cheaper and better soon ...<p>[1] <a href="http://www.cclonline.com/product/95902/U2713HM/Monitors/Dell-UltraSharp-U2713HM-27-Widescreen-LED-Monitor/MON1192/" rel="nofollow">http://www.cclonline.com/product/95902/U2713HM/Monitors/Dell...</a>
I'd buy one if I knew it would work. Heck, I'd buy two or four for a multimonitor setup. The process of figuring out whether a given laptop or graphics card will drive 4k over a particular standard is daunting. Knowing if it will work with Ubuntu, in particular, is beyond me.<p>I wish there was a standard -- perhaps over USB -- where ordinary people who don't play games and just want a machine to work on (emacs, xterms, web browsers, word processors, rather than gaming) could make many monitors and large monitors work plug-and-play.
> The sRGB option does produce colors that appear to be closer to our post-calibration settings than the default "standard" mode, for what it's worth.<p>Hmmmm... I need something that can do a little better than "closer to". Guess $650 and color accuracy is too much to ask at 4k.
So how long till we get 4K touch displays?<p>These displays are fantastic, but I'd worry about touch models being released in a couple of years. If you use Windows, or OS X gets good touch support, you might regret the purchase.
why not a seiki 39" 4k for $399?<p><a href="http://www.amazon.com/Seiki-SE39UY04-39-Inch-Ultra-120Hz/dp/B00DOPGO2G/" rel="nofollow">http://www.amazon.com/Seiki-SE39UY04-39-Inch-Ultra-120Hz/dp/...</a>
Can someone explain how this is 4k? Apple's Thunderbolt Display has a resolution of 2560x1440 [1] and ASUS' PB287Q also has 2560x1440 according to Amazon [2].<p>What am I missing? UPDATE: I transposed digits and looked at the PB278Q not the PB287Q.<p>[1] <a href="https://www.apple.com/displays/specs.html" rel="nofollow">https://www.apple.com/displays/specs.html</a><p>[2] <a href="http://www.amazon.com/PB278Q-27-Inch-LED-lit-Professional-Graphics/dp/B009C3M7H0" rel="nofollow">http://www.amazon.com/PB278Q-27-Inch-LED-lit-Professional-Gr...</a>
