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.

    Any word on Abobe RGB colour gamut? And what type of back light?
  • 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.

    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.

    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.

    I would like to see these large monitors with at least half the PPI/DPI (200+) of high end phones, we can dream, so it is good to see some progress after years of regression. 10-bit colors have been around for years now, even though it has not been fully exploited, so I do not have an issue with the order of importance you listed as this is what I believe the industry needs to concentrate on. In the process of doing this they can now standardize and fully exploit 10-bit colors which should help your issue.

    Hey that's not bad. Cheapest 4K monitor yet. The prices are coming down quicker than I thought. Once 4K drops to ~$1000, I'll start considering it.

    3840x2160 = 8.294.400, so its 8k, right? 4k is 2560x1600
  • ingwe - Monday, June 10, 2013 - link

    4K is approximately 3840. 8.294.400 is not 8k, that is 8 million.
  • apertotes - Monday, June 10, 2013 - link

    Why then 2560x1600 is called as 4k?
  • Blindsay - Monday, June 10, 2013 - link

    2560x1600 is not referred to as 4k
