Following ASUS' $799 28-inch 4K monitor from earlier this year, the Taiwanese tech giant has today unveiled yet another high-res display, but this time it's aimed at semi-professionals instead of mainstream users. The new ProArt Monitor PA328Q is a 32-inch, 16:9 3840 x 2160 monitor, and it boasts factory calibration with 10-bit color, 100-percent sRGB color gamut plus 350cd/m² brightness. On the back, you'll find three HDMI ports (one of which with built-in MHL 3.0), one DisplayPort 1.2, one Mini DisplayPort 1.2 and four USB 3.0 ports. ASUS added that this pretty monitor lets you adjust its tilt, swivel, pivot and height.
As with many product announcements today at Computex, ASUS doesn't yet have a solid date or price for the PA328Q, but our understanding is that it's aiming for around half the price of the high-end $3,799 PQ series when it lands in Q4. If you need something fairly reliable for your graphics projects but are stuck with a smaller budget, then this monitor is probably worth your consideration -- if you can wait for it, that is.
