Asus just announced their ProArt PQ22UC, a 21.6" OLED monitor with a massive 3840x2160 pixels resolution, it's HDR compatible as well. The screen is intended as a portable monitor and weighs about one kilogram.
The ASUS ProArt PQ22UC takes no-compromise content editing and creating on the road with a professional-grade 4K OLED boasting HDR support. And you can leave outlets behind with the battery-powered ZenScreen Go MB16AP, which stashes in a laptop bag and hooks up to computers or phones to provide maximum versatility for anyone who travels.
Measuring an expansive 21.6”, the PQ22UC bucks the trend for portable monitors by providing a canvas that almost matches the size of a desktop monitor but is still light enough to carry between client meetings all day. Thanks to its thin-and-light OLED panel, the display weighs in at just 2.2 lbs; that’s less than our premium ZenBook 3 Deluxe ultrabook, making the PQ22UC a great alternative to a hefty portfolio filled with hard copies of your best work.
