Product Description
LG UltraGear 27GN800P-B, 27" Manual Overview
The LG UltraGear 27GN800P-B is a 27-inch QHD (2560 x 1440) gaming monitor designed for competitive and immersive play. Built with a high-refresh 144 Hz panel, 10-bit color support, and adaptive sync technologies, it balances fast response times with vivid image quality. The monitor features a sturdy stand with tilt adjustment (-5° to 15°), VESA 100 x 100 compatibility for wall mounting, and practical ergonomics including a bottom-mounted joystick control for on-screen display (OSD) navigation and quick access to input, volume, brightness, and power.
Key Features and Practical Use
Equipped with DisplayPort 1.4 and HDMI inputs, the UltraGear supports high refresh rates and HDR-effect modes when paired with compatible GPUs. Adaptive-Sync (FreeSync/G-SYNC compatibility depending on connection and GPU) reduces tearing and stutter, while Motion Blur Reduction and selectable response time settings (Off, Normal, Fast, Faster) help maintain clarity in fast-paced titles. The Game Mode presets (Gamer 1/2, FPS, RTS, Vivid, Reader) and customizable color temperature, gamma, and six-color adjustments make it easy to tailor the image for gaming, media, or productivity.
Connectivity extends to a headphones jack for audio out and a USB port dedicated to firmware updates. LG recommends certified HDMI cables and matching DP versions to ensure proper audio/video transmission. The monitor supports plug-and-play functionality but suggests installing the latest monitor drivers from LG for best compatibility.
Safety, Setup and Maintenance
The manual emphasizes using genuine components and following safe assembly—avoid excessive screw torque, do not carry the screen by the stand alone, and keep the monitor upright when transporting. It recommends keeping 100 mm clearance for ventilation when on a desk or wall-mounted. Notes cover Kensington lock usage, cable management, and best practices for installing wall mounts and choosing appropriate screw lengths to prevent damage. The USB port is reserved for software updates, and firmware files must be placed in an LG_MNT folder on FAT/FAT32/NTFS drives.
Performance & Troubleshooting
Expect typical operating power around 43 W and sleep/off modes under 0.3 W. The manual includes factory preset timings and a troubleshooting section addressing common issues: no signal, incorrect resolution, image retention, color depth settings, and audio routing via the monitor. It also explains vertical/horizontal frequency concepts and advises matching GPU output to recommended resolutions to avoid flicker or distortion.
Notes
- Recommended resolution and refresh: 2560 x 1440 @ 144 Hz.
- Use certified HDMI/DP cables and match DP version (1.4 for HDR).
- Firmware updates require LG-formatted upgrade files in LG_MNT folder.
