[Engadget] Alienware's 55-inch 4K OLED gaming monitor is pure eye candy
So what makes this Alienware display different than a typical OLED TV? For one, it supports a variable refresh rate all the way to its maximum 120Hz refresh rate, whereas many TVs are locked to 120Hz if they support it. Additionally, it features a DisplayPort 1.4 connection, which supports 4K all the way up to its high refresh rate.
It looks like LG's 2019 OLEDs will have some real competition.
