Gigabyte has released a new 55-inch 4K gaming monitor, which is full of modern technology. The specifications of Gigabyte S55U are such that it looks like a very attractive product without raising concerns that it may be financially unaffordable. In other words, this can be a great product if you’re looking for an AMD FreeSync Premium compatible alternative to an Nvidia-certified large-format gaming display.

There are a lot of good looking specifications here, so we’ll put them in a full-featured table below. First, the 55-inch 4K panel uses VA quantum dot technology to provide strong and vibrant colors. In addition to good performance for a panel of this size and resolution, offering only 2 ms response time and up to 120 Hz refresh rate, this monitor has stunning brightness and contrast statistics with a color gamut of 96% DCI-P3. Contrast in games and content consumption will be enhanced by an array of 132 local dimming zones.

Gigabyte’s offer is not just a beautiful screen; the additional features are also quite extensive. This monitor uses the Android operating system and has a built-in Google Assistant with built-in Chromecast. It has dual 10W speakers with Dolby Atmos / DTS HD and a wide selection of preset sound profiles. In addition, there is an extensive collection of ports, including the latest HDMI 2.1, various USB ports, Ethernet, as well as Wi-Fi and Bluetooth connectivity.
