The OLED screen has a 120Hz refresh rate, a 0.5ms response time, and should have 400cd/m2 brightness with 130,000:1 contrast ratio. With a resolution of 3840x2160 on a 55-inch panel, it gives it a pixel density of 81ppi.
The Alienware 55 AW5520QF monitor comes with a dedicated remote. Other than these specifications, there is not much to be said about Alienware's big screen, other than it will have support for AMD FreeSync, has a VESA mount support, and will feature DisplayPort and HDMI inputs, alongside USB ports.
There is also no word on worldwide availability as so far, it is only coming to North America.
