A:Answer According to an online review by Digital Trends, "Unfortunately, the M-Series falls short of being a gamer’s best friend. While it offers auto low-latency mode (ALLM) which helps greatly with input lag, it doesn’t support any flavor of variable refresh rate (VRR) technology, which is becoming increasingly desirable for both console and PC gamers alike. Moreover, it’s not yet clear how gamers will be able to take advantage of the M-Series’ 120Hz capabilities — the TV has four HDMI 2.1 ports, but these only support 4K @ 60Hz. With that limitation, only gaming apps that can be added to the TV via the Fire TV app store will be able to avail themselves of the TV’s 120Hz panel."
