Pixel Overload: Asus Announces 31.5-inch 4K Ultra HD (3,840 x 2,160) Monitor

Finally, another large screen monitor for PCs!

There are only a handful of 30-inch PC monitors to choose from, compared to, say, 24-inch panels, of which you could spend an entire weekend just researching all the different options. For that reason, we can't help but get a little excited when a display maker announces a new large screen monitor, only Asus didn't stop at 30 inches. The new PQ321 Asus unveiled is actually 31.5 inches, slightly larger than the competition.

That additional real estate is put to use displaying a 3,840 x 2,160 resolution, otherwise known as 4K Ultra HD. That's four times the resolution of a Full HD 1080p display, though the pixels per inch count (140ppi) isn't anything to get overly excited about, not when mobile devices are boasting so-called Retina-class displays (to borrow a term from Apple).

In any event, the PQ321 supports 10-bit RGB "deep color" and features a wide 176-degree viewing angle on both vertical and horizontal planes. It uses Indium Gallium Zinc Oxide (IGZO) rather than traditional amorphous silicon for the active layer of its LCD panel because it supports smaller transistors, thus making it possible to cram all those pixels into a 31.5-inch panel, Asus says .

Other features include an 8ms gray-to-gray response time, Picture-by-Picture support, built-in 2W stereo speakers, and dual HDMI inputs.
