20-inch Panasonic tablet has 4K resolution, GeForce graphics

As device makers seem to be focusing on smaller tablets, Panasonic is moving in the opposite direction. The company has unviled a jumbo tablet with a 20" screen and a 4K display resolution. The Toughpad 4K UT-MB5's 15:10 aspect ratio is a little unusual, but the 3840x2560 resolution adds up to 9.8 megapixels—more than the 8.3 megapixels offered by 4K displays with more typical 3840x2160 layouts. When you factor in the screen's dimensions, the pixel density works out to 230 PPI.

Panasonic doesn't envision the Toughpad as a super-sized couch surfer. Instead, the tablet is meant for designers, architects, engineers, and other professionals. It comes with a custom stylus, too. The so-called Electronic Touch Pen connects via Bluetooth and "uses infrared signals to distinctly read every single pixel on the screen." Panasonic says the stylus boasts 2048 levels of pressure sensitivity and the ability to track the angle at which it's being held.

Although the stylus sounds interesting, it looks bigger than a giant Jiffy marker. Everything about the Toughpad is oversized, apparently.

The Toughpad 4K UT-MB5 is powered by a Core i5 CPU backed by a discrete GeForce graphics. Panasonic's press release doesn't mention more specifics on the chips, but it says the tablet comes with 8GB of RAM, 256GB of solid-state storage, a USB 3.0 port, and an SD card reader. The whole thing measures 0.5" thick and weighs 5.2 lbs. If you have to ask how much it costs, well, you know.
