After launching its first 4K laptop in the UK, Toshiba has just announced US availability. It’ll be the P55T rather than the P50T, but as before, it’s a 15.6-inch laptop with a 3,840 x 2,160 pixels resolution — a staggering 282 PPI, if you’re scoring at home. Driving all those pixels is an AMD 2GB DDR5 Radeon R9 M265X graphics card, 4th-gen Intel core i7 CPU, 16GB DDR3L max memory and a 4K-ready HDMI port.
