Gigabyte's 28-inch 4K 144Hz IPS gaming monitor pairs two full-bandwidth HDMI 2.1 ports with a DisplayPort 1.4 (DSC) input, so it can take 4K at 120Hz from a console or 144Hz from a PC. Its USB-C port accepts a DisplayPort Alt Mode video signal and supplies 18W of power — useful for a tablet or phone, but not enough to charge a laptop. A built-in KVM switch lets one keyboard and mouse control two connected computers. The monitor includes a three-port USB 3.0 hub and a headphone jack, and it runs from an external power brick.
