With the UltraGear 48GQ900-B, LG offers a high-end gaming monitor aimed at gamers with particularly high demands. With its large 47.5-inch screen, 4K resolution, and a refresh rate of up to 120 Hz, along with a 0.1 ms GtG response time, the monitor is excellent for gaming. The OLED display with 10-bit colors delivers stunning visuals with HDR10. The certification with AMD FreeSync Premium and Nvidia G-Sync Compatible allows for variable refresh rate adjustment and prevents tearing.
Visually, the LG UltraGear 48GQ900-B also impresses: the slim display bezels, low stand, and modern black design give the gaming monitor a contemporary and high-quality appearance. The display can also be mounted on alternative monitor brackets via the 300 x 200 mm VESA mount.
For rich sound, it features two built-in speakers with 20 watts each. An integrated USB 3.0 hub with two Type-A ports is also provided. You can easily adjust the monitor's settings using the included remote control.
