ASUS announced its 31.5-inch "4K" display prior to Computex, but it was at the show that I got a chance to lay eyes on the highly anticipated display. The PQ321 features a 3840 x 2160 Sharp IGZO panel and will sell for $3799. The price point is closely tied to Sharp's panel cost, so as production increases in response to demand we should see prices fall.

Driving the 4K display will require either a DP 1.2 output or two HDMI outputs. ASUS' Computex demo had two of its panels (one 31.5" and a 39" version as well) running off of the same system, both driven off DisplayPort outputs.

Although the demo ran at 30Hz, ASUS claims it has a display setting that will allow 60Hz operation using DisplayPort.

    I find it gimmicky. What does TV need with 4K when 1080p approches what human vision can resolve at the distance most people watch TV? 1600 itself would be more than enough. I dont see it actually gaining anything except trying to revitalize the TV market for people with more money than sense.

    For PC more resolution the better even past what a human can resolve as smooth due to the nature of the PC environment. More room for windows, better font rendering (goodbye cleartype), etc etc.

    $500 4K is at least 2 years away :( Reply

    You know what would be great? If they start handling it out for free. :-D Reply

    a 24" 4K monitor is probably overkill don't ya think??? I'm not interested in doing the math to get the angular size of a pixel from a meter but my guess is that 1080p probably is sharper than the eye can reconcile. Just a quick guess. 1440p would probably be pretty cool at 24". Right now I'm on my 27" 1440p monitor and surely it is great and could use some retinizing, but 24" is crazy. I'm thinking to stay relevant the desktop will go jumbo. (31" sounds great!) Reply

    There are different useful definitions of what the eye can resolve. Sure, 1080p for most screens will not look pixelated to anybody, but at the same time the GPU companies put a lot of effort into Oversampling tricks in order to keep Aliasing-Artifacts in check. By increasing the physical resolution of the screen you will finally get to the point where you no longer need any AA modes, as you basically apply "biological anti-aliasing".
    Also, fine details like texts will look better on a higher resolution, even if you can't really make out the pixel in the "high enough" resolution. Keep in mind, that magazine printing is often done with resolutions of 1200 or even 2400 DPI, achieving that would actually require a 25K or 50K resolution on a 24" screen. You might keep your head further from a monitor than from a magazine, but I definitely think 8K on a 24" would still remain useful for anybody working with a lot of text. And you can always scale down for games and movies, where you can't afford those high resolutions.

    Yep, sharper text is all what I am looking for. My eyes are not anymore so good as years ago, so better and sharper PC monitor would help a lot! 8K is not too much in 24" it would still be less than we now have in phones! in ppi I mean... Reply

    Any word on Abobe RGB colour gamut? And what type of back light? Reply
  • zanon - Monday, June 10, 2013 - link

    I too would be interested in that, as well as progress on improved backlighting such as quantum dot films with LEDs. I think though that color has to take a back seat until we get a better connector. Without a true 10/12-bit panel, a higher gamut means larger steps between colors and potentially worse images for a lot of uses. Better color is where we should be aiming, and it's a target for UHDTV (see Rec 2020). But standard gamut increases need to go hand in hand with additional space, and that takes bandwidth which we don't have right now. Reply

    What do you mean a better connector? DisplayPort 1.2 supports 3840×2160 @ 60 Hz with 10-bit colour (1.073 billion colours), and many high-end monitors are 10-bit, i'm using two right now. Reply

    I want to see beyond 2160p and 60 Hz, and the industry overall has seemed to put feature importance in order of resolution > refresh > color. I'd be happy to be wrong but I was guessing that the former would be prioritized over the latter. If DP1.2 is all we get for another few years though then you're probably right that everything will settle around UHDTV specs. Reply
