"It was only a few years ago that 4K panels were the cutting-edge technology on display at CES. For the last few years, we’ve seen 8K televisions popping up here and there, more as proof-of-concepts than actual practical products. Dell’s new display announcements aren’t just products the company plans to build some day; they’re cutting-edge hardware that’s coming to market this year.
First up, we’ve got the Dell UltraSharp 32 Ultra HD 8K monitor (UP3218K). This new 8K panel offers 33.2 million pixels in a 32-inch screen — that’s 7680×4320 — for an average pixel density of 275 PPI. Measurements like this indirectly reveal the reason most monitors don’t try to push resolutions the way smartphones do. The pixel density you need to not be able to see individual pixels falls off steeply as the distance between your eyes and the display increases. A 2560×1600 32-inch panel is considered “retina” (meaning the typical human eye cannot distinguish between pixels) at 36 inches. A 4K panel of the same physical size is retina at 25 inches. An 8K panel hits that mark at the one-foot mark, but precious few people use a 32-inch display while sitting just 12 inches from the screen."
Top level professional video and photography editors perhaps, people who chuck $10,000 at a graphics card and write it off as a business expense, need this monitor because they natively work with images that large, but can you imagine playing a game at 8K on a tiny 32 inch monitor? You'd need a healthy supply of
