This article covers LG UltraGear FHD 27-Inch Gaming Monitor 27GN800-B.

Overview

The LG UltraGear 27GN800-B is a 27-inch Full HD (1920×1080) IPS gaming monitor with a 144Hz refresh rate and 1ms (GtG) response time. It's designed for competitive gamers who need smooth, tear-free visuals without breaking the bank. The panel supports both NVIDIA G-Sync Compatible and AMD FreeSync Premium, effectively eliminating screen tearing and stuttering during fast-paced gameplay. Thanks to its IPS technology, the monitor offers wide 178° viewing angles and sRGB 99% color coverage, making it suitable not only for gaming but also for media consumption and light creative work. HDR10 compatibility adds extra contrast when viewing supported content.

Connectivity & Compatibility

The monitor provides one DisplayPort 1.4 and two HDMI 2.0 inputs. The DisplayPort connection delivers full 144Hz at 1080p without compression. HDMI also supports 144Hz, though bandwidth limitations may apply depending on the source device. A 3.5mm headphone jack is available for audio output. There are no built-in speakers, so external audio is required. Adaptive sync works via DisplayPort for G-Sync Compatible, and both HDMI and DisplayPort for FreeSync Premium.

Product Info

Released in 2020, the LG 27GN800-B remains widely available through major retailers. It sits in the mid-range tier for 27-inch 144Hz IPS monitors, typically priced between $250 and $350 USD. The package includes a DisplayPort cable, HDMI cable, power cord, and quick setup guide. The stand offers only tilt adjustment; height, swivel, and pivot are not supported. VESA 100×100mm mounting is available for arm or wall mounting. Warranty is the standard one year from LG (may vary by region).

Best Use Cases

Competitive FPS gamers: The 144Hz refresh rate and 1ms response provide a clear advantage in fast-twitch shooters. Adaptive sync ensures smooth motion. However, the 1080p resolution may feel limiting for those accustomed to higher pixel densities. Budget-conscious buyers seeking high performance: This monitor delivers a solid 27-inch IPS 144Hz experience at an affordable price. Color accuracy is decent for everyday use and casual content creation. Multi-monitor setups: The slim bezels and VESA compatibility make it easy to align multiple units for an immersive surround gaming or productivity workspace. Light creative work: sRGB 99% coverage is sufficient for photo editing and basic video work. Professionals needing DCI-P3 or Adobe RGB should look at higher-tier models.
