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."

    But if you are willing to go up to a larger screen, 27" or above then you can get a size of 2560x1440. But you have to pay for it.

    Not as much as you might think, if you don't care about name brands. Search for "Yamakasi Catleap" on eBay. These are South Korean-made 27" monitors with 2560x1440 resolution. They cost $300-$320 including shipping. I don't own one myself, but they seem to be fairly well regarded by those who do. The panels are probably made by the same companies as the name brand monitors anyway, since there aren't that many panel vendors out there.

    What we really need to do is to blame the HDTV format which forces us to get those letterbox size screens.

    The designers of ATSC chose a 16:9 aspect ratio because it matches many theatrical films and offers a better viewing experience than 4:3 on movies and TV shows. It wasn't their intent to create a de facto standard for computer monitors; that is due to cost-cutting on the part of the consumer electronics industry.

    High density PPI displays are extremely expensive to produce because of the zero-defect-over-large-surface-area manufacturing issues.

    This. The failure rate for a panel equals the subpixel failure rate times the number of subpixels. A 2x increase in DPI means at minimum a 4x increase in the percentage of defective panels, and that's if you managed to keep the subpixel failure rate constant as you doubled the density. In practice, I'd expect it to be worse than 4x. And even at current DPIs, I've read that large LCD panels still have about a 10% reject rate as of a couple of years ago, which means you'd probably have to toss about half of them if you doubled the DPI....

    On the other hand, if they did it right, they could ostensibly build the panels in such a way that a defective panel could be remanufactured into a dozen smaller panels for mobile phone use (discarding the one with the bad subpixel), and then they could cut their waste to near zero. I wonder if anybody has attempted such a design....

    How you got modded Informative is beyond me. Repeat after me: 1080p is a resolution, not a density, and you need to standardize on a density to achieve economy of scale.

    Manufacturers make panels with specific pixel densities. They can then cut those panels to a number of different sizes in order to achieve a number of different resolutions. If I cut a high-density panel at a small size, I can get 1080p, or I could cut a low-density display at a large size to also achieve 1080p. 1080p just means that there are 1920 pixels across the display and 1080 pixels down the display, but it gives no indication of how you got there. And because there are dozens or hundreds of different density panels to choose from, you cannot achieve economies of scale unless you standardize on specific densities.

    As for "good enough", it's all a matter of what we can see. The iPhone 4's display was called a "Retina Display" because it had passed the threshold at which the human eye could distinguish individual pixels when held at a normal viewing distance (12" was what they said, I believe). Similarly, the new iPad has a Retina Display even though it had a lower pixel density, because they consider a normal viewing distance for it to be slightly further away. "Good enough" for most people will be at the point when they can no longer distinguish pixels. At that point, the pixel density race will likely become about as moot as the dpi race between printer manufacturers was, and as the megapixel race between camera manufacturers is quickly becoming (note: there are benefits to more megapixels, but they're already past the point where the normal user cares since most of them aren't blowing up their images afterwards).

    Of course, there are benefits to going even higher in density than "retina" levels, since Vernier acuity allows us to still distinguish slight variations in lines, even if we are not able to distinguish the individual pixels making them up. As a result, you can still make curves look smoother or straighter by increasing the pixel density further.

    Recently...I was looking for a new set up, both for a job I was contracting to do (windows based)...needing large screen for multiple windows at once...and also, I had just bought a new Canon 5D3, and looking to edit high resolution stills and HD video....this was on a macbook pro I gave myself last year. Contract was paying for the monitor, nice side job.

    Anyway, wanting something nice, I had a major surprise trying to find something larger that 1080p.....I shopped around and finally found the best deal I could on a Dell u2711....2560x1440.

    I paid about $800 on it, most priced it then about $1K.

    I was shocked, not so much at the price, which was steeper than I'd thought...but at the sheer lack of higher resolution monitors out there even available.

    I mean...nice that TVs are all nice 1080p, but the influence has seemingly killed the computer monitor market.

    I guess like how the general public has forgotten what good sound reproduction can be, and the value of it.....we've lost how nice a higher end resolution monitor can be for working. Sure...multiple monitors are nice, but why not START with a nice big high resolution one...and later..save and pair THAT with a 2nd nice one?

    Sure is nice having a LOT on one screen....having multiple 'screens' with lots of real estate on them is even nicer.....double that eventually..and..well...

    Looking around my office most people sit about 20" from their monitor but hold a smartphone 12" away from their face. With 20:20 vision are humans able to see 326ppi at 20"? I would guess not.

    A few months ago I got a used IBM T221. 3840 x 2400. It makes ALL the difference in the world! I can actually easily fit 3 browsers up side by side even when viewing all those fixed-width fullscreen-expecting websites out there, and they all look sharp and crisp. I can have a tall browser, tall IDE, and two extra large xterms all within instant field of view, all rendered clearly. A pleasure to look at.

    My coding productivity has gone up simply by not having to constantly click around to uncover one buried window or another. I can fit dense text, code, and references on the screen without making it unreadable due to too few pixels per character.

    And then there's picture editing. You haven't truly seen godly image quality, until you've seen a well-composed picture taken with a good-quality camera rendered in all its glory at better than 4x the resolution of HDTV. And, of course, video editing: a full-resolution HDTV clip takes up one corner of the screen. Plenty of room for menus browsers and even a second or third video source.

    Simply put, you have no idea what you're missing. It really is *that* good.
