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 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. Reply

    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. Reply

    3840x2160 = 8.294.400, so its 8k, right? 4k is 2560x1600 Reply

    4K is approximately 3840. 8.294.400 is not 8k, that is 8 million. Reply

    Why then 2560x1600 is called as 4k? Reply

    2560x1600 is not referred to as 4k Reply

    Was it possible to determine whether this uses DP 1.2 MST like the Sharp PN-K321, or does it actually present as 1 full 3840x2160 surface over DP? Reply

    Too much just to beta test 4k. Reply

    True, but a 4k$ offer in June from ASUS, one month after the 6k$ offer from Sharp, which came in one month after the 20k$ offer from EIZO ... looks like we might get something for below 2k$ for Christmas this year. Reply

    IBM actually brought out a QUWXGA (3840*2160) monitor in 2000 or 2001, if I remember correctly. It was 22", had 2 AC adapters, and ran at 60 Hz. The original list price was around $30,000. Last I remember, it was about $11,000 but that was in about 2004. Reply
