Update: Pricing has just been announced, at $3,799. Pricey, but actually not bad value in a market that had five-figure pricing not so long ago.

ASUS today revealed that it will launch a 31.5-inch 4k monitor late next month, its 3840×2160 pixels allowing four 1080p HD videos to display full-size on the same screen without overlap. A 4k monitor in such a small package is made possible by using an IGZO panel, whose smaller transistors enable greater pixel density, and is likely to be in the same league (and possibly from the same manufacturer) as the 32-inch Sharp panel we saw at CES.

However, don’t rush out to buy one just yet: it’s unlikely that even a top-spec Mac from today’s line-up would be able to drive the resolution at a decent frame-rate. But the next-generation of Haswell-powered Macs almost certainly will. Indeed, as we mentioned earlier, it’s even possible that a next-generation MacBook Air could do so …

No pricing has yet been announced, but the monitor is aimed at the video pro market so you can expect it to cost considerably more than the shiny new Mac you’ll connect to it.
