ASUS Launches PQ321 Monitor with 3840 x 2160 IGZO Display
ASUS today announced the PQ321 True 4K UHD Monitor, a desktop display with a stunning Ultra HD 3840 x 2160 resolution that’s equivalent to four Full HD displays stacked side-by-side. The PQ321 has a 31.5-inch LED-backlit 4K Ultra HD display (140 pixels-per-inch) with 16:9 aspect ratio, and supports 10-bit RGB ‘deep color’ for vibrant images with more natural transitions between hues.
Cutting-edge IGZO panel technology
The ASUS PQ321 True 4K UHD Monitor uses cutting-edge Indium Gallium Zinc Oxide (IGZO) rather than traditional amorphous silicon for the active layer of its LCD panel. IGZO panels support much smaller transistors than amorphous silicon, which in turn gives much smaller pixels and the 3840 x 2160 resolution of the PQ321 is four times that of a 1920 x 1080 Full HD display.
176-degree wide viewing angles on both vertical and horizontal planes minimize onscreen color shift, while the 350cd/m² brightness rating and 8ms gray-to-gray response time ensure smooth, bright, and vibrant moving visuals. IGZO technology also gives reduced energy consumption compared to amorphous silicon and reduces bulk — at 35mm at its thickest point, the PQ321 is the thinnest 4K UHD monitor available today.
Comprehensive video inputs for UHD content
The ASUS PQ321 True 4K UHD Monitor features DisplayPort and US models offer dual-HDMI ports inputs with Picture-by-Picture support. Built-in 2W stereo speakers remove the need for additional desktop clutter and, in addition to being wall-mountable, the monitor stand offers full height, swivel, and tilt adjustment.
ASUS will be exhibiting the 39-inch and 31.5-inch True 4K UHD Monitor models at Computex 2013 in Taipei.
The ASUS PQ321 True 4K UHD Monitor will be available in North America in the end of June. Please contact your local ASUS representative for further information.

4k x 2k and it can only support up to 60hz with DP.... at whatever top of the line price tag they come up with I wouldn't put out the cash. 85hz minimum, I demand!
I donno how they keep coming up with this 60hz max garbage. you can't game on it happily above 20". at 30" already looks weird on desktops on 1080p...
Blame Display Port technology and its bandwidth, 60Hz is the max it can handle at 4K HD.
