Ahead of CES 2017 LG has announced their upcoming monitor lineup, which features an HDR (high dynamic range) model. The 32UD99 is a 32-inch, 3840 x 2160 IPS display that offers 95% DCI-P3 color and HDR10 support. (Specifics as to peak brightness, rated black levels have not been released.)
From LG's press release (pdf):
“As the availability of HDR (high dynamic range) content continues to expand across a wide range of categories, from movies to games, LG is leading the way in bringing this enhancement to desktop monitors,” said to Tim Alessi, head of product marketing at LG Electronics USA. “The enhanced picture quality offered by HDR technology is instantly recognizable to even the most casual user, and manufacturers are already pushing this promising technology to its fullest potential. From high-resolution displays compatible with HDR technology, to UltraWide monitors optimized for multitasking and gaming, LG is committed to delivering the most state-of-the-art and premium monitors in the industry today.”
HDR is a somewhat complex standard, incorporating requirements for bit depth and supported color space, brightness level, and black levels for the display – along with compatibility with one of the HDR standards; HDR10 or Dolby Vision. The fact that LG is using IPS for their new montior seems problematic given the high black levels associated with IPS (unless sophisticated local dimming is employed, such as with LG's Infinia televisions of a few years ago), as most HDR sets employ a VA panel of some kind. Of note, rival Panasonic only recently announced their work on very high native contrast IPS panels, but there is no indication that LG has developed a similar technology at this point.
HDR is all the rage in the 4K television world, and for gaming both Sony and Microsoft's latest consoles support the more common HDR10 implementation – with compatible games, UHD Blu-ray, and streaming content, that is. It was inevitable that HDR would make its way into the computer display space, and presumably more and more PC games will be offering support going forward (Shadow Warrior 2 was the first title to support HDR on PC). A quick primer on HDR (with respect to the "Premium" standard from the UHD Alliance) can be found here, and only time will tell if the HDR10 standard will win out over Dolby Vision, though at this point it seems likely.
