The LG UltraGear OLED 27GX704A-B is a 27-inch monitor designed for high-performance gaming. It features an OLED panel with a QHD resolution of 2560 x 1440 pixels, which provides a high contrast ratio of 1500000:1 and deep black levels. Motion clarity is addressed with a 240 Hz refresh rate and a 0.03 ms grey-to-grey response time, resulting in fluid visuals during fast-paced sequences. The display reaches a peak brightness of 1300 cd/m², contributing to visibility in various lighting conditions. Its 16:9 aspect ratio and flat screen shape provide a standard viewing format suitable for a wide range of content and applications.
Visual fidelity is supported by 10-bit colour depth, enabling the display of over one billion colours and covering 98.5% of the DCI-P3 colour gamut. The monitor is compatible with VESA DisplayHDR True Black 400 and HDR10 for enhanced dynamic range in supported media. To ensure smooth, tear-free gameplay, it integrates both NVIDIA G-SYNC compatibility and AMD FreeSync Premium Pro technology. User comfort is addressed through an anti-glare screen surface, flicker-free technology, and a low blue light mode, while wide 178-degree horizontal and vertical viewing angles maintain colour consistency from different positions.
Connectivity options include two HDMI 2.1 ports, one DisplayPort 1.4 port, and a headphone out jack. A built-in USB 3.0 hub with two downstream ports allows for the connection of peripherals directly to the monitor. The included stand offers comprehensive ergonomic adjustments, including height, tilt, swivel, and a 90-degree pivot for vertical orientation. For alternative mounting solutions, the monitor is compatible with a 100 x 100 mm VESA interface. This model operates with an SDR energy efficiency class of G.
