Where Are All the High-Resolution Desktop Displays?
MrSeb writes "Ever since the release of the iPhone 4 with its 326 pixels-per-inch (PPI) Retina display, people have wondered about the lack of high-PPI desktop displays. The fact is, high-resolution desktop displays do exist, but they're incredibly expensive and usually only used for medical applications. Here, ExtremeTech dives into the world of desktop displays and tries to work out why consumer-oriented desktop displays seem to be stuck at 1920x1080, and whether future technologies like IGZO and OLED might finally spur manufacturers to make reasonably-priced models with a PPI over 100."
Neither of the most popular desktop operating systems (Windows, OS X) work very well at arbitrary DPI. Windows is surprisingly ahead of OS X at the OS level, but lots of windows applications misbehave if you change the DPI settings. For example hard-coded interface layouts can mean that controls will be displayed outside the window area and are therefore inaccessible.
The DuraVision FDH3601 from EIZO is one example.
Expect to pay tens of thousands of dollars for it, though - these are targeted at oil companies and government.
Conveniently, the latest Intel chipsets can apparently handle such "4K" resolutions.
Village idiot in some extremely smart villages.
That might have been high dpi, but the resolution was nothing special. In 2001 IBM blew that out of the water @ 204dpi covering a full 22", and nothing sine has come close. It's the only piece of computer hardware where "I wish they made 'em like they used to" comes to mind.

I'd like to see high resolution displays as much as the next guy, but it's much less necessary on desktop displays and television sets.
I'm sure someone will freak out about me saying that, but here's the thing: it's not just about DPI, but about the viewing distance. The reason the retina display is called "retina" is that (we can argue about the validity of the claim, but...) it's roughly the maximum resolution discernible by the human eye at the distance you're expected to view a smartphone. That is, approximately a foot away from your eyes.
Your desktop display should be about 3 feet from your eyes. My TV at home sits... I don't know, somewhere around 12 feet from my eyes. Though it might be really cool to get a 300 dpi television, I'm not sure it makes sense to worry about it when you're talking about a television that's 12 feet away.
Yeah, this article's assumptions about pricing already seem like some quaint notions around three years out of date. These higher-res monitors are now appearing in retail:

Or when you think about it - prices haven't really changed all that much. Prices on the low end have dropped, but good stuff is still priced pretty much the same as it has over the years.
A good 20" CRT monitor would've cost $2000+ easy in the 90s (one that could do 16x12 and not be fuzzy/blurry/blooming but nice and crisp). Heck, a 17" monitor doing 1024x768 flatscreen would've been several hundred bucks.
Likewise, nice monitors are still several hundred bucks. It's just that we're used to seeing huge 20" LCD monitors go for $100 or less that makes us think they're a good deal. It's the same as a $500 laptop - the good ones still cost a lot of money (want a GPU and more than 1366x768? You'll be spending $1000 minimum).
All that's happened to technology is manufacturers have perfected the art of making something to a price. A laptop for $500? What bits and pieces can we chop for that? A monitor for $100? Sure! What can we sacrifice?
Ditto 1080p displays - because of the commodization of technology, the video circuits to drive a 1080p display is insanely cheap - when millions of TVs are made, it's easy to make a very cheap computer monitor by reusing the exact same parts.
Anyhow, hopefully the Apple rumors are true and high-res displays are coming down the pipeline.
Interesting. The Shimian and Catleap have been around for a few months now, at least, at under $350 shipped. Not only are they both 2560x1440 IPS displays, but the Catleap was able to do 120Hz, and a new set of 120Hz capable Catleaps are being produced.
Sucks to be you.
40/40 vision is the same as 20/20 vision. 20/20 vision is considered to be "normal"; 20/40 is half as good as 20/20, while 20/10 is twice as good. The numerator refers to the distance of the observer from the chart in feet. The denominator is more complicated, but essentially refers to the distance between lines on the chart (according to Wikipedia this is measured in mm, which I find odd given that the numerator is measured in feet).

Indeed. 1080p is kind of a downgrade for those of us who had higher resolution monitors from yesteryear.

Shimian panels are rejects from Apple, meaning that they often have problems.
It's buyer beware and the fact that you have to get it shipped from Korea means that you're probably not going to be able to return it. That said, they're cheap and often good so, you know, there you are.
