A company called Wasabi Mango has released the world's first commercially available 4K monitor with a 120Hz resolution, beating some established players to the punch, including Acer, Asus, LG, and Samsung.

It's a large size 43-inch monitor with a simple 'UHD430' model name. It has two DisplayPort 1.4 connectors, which support 4K at 120Hz (the DisplayPort 1.4 spec also supports 8K at 60Hz), plus three HDMI 2.0 ports, a Toslink optical audio output, and a USB port.
