Key Features
QHD IPS Display
The 2560 × 1440 resolution delivers detailed images and a larger workspace than Full HD. IPS technology provides wide viewing angles and consistent-looking colours across the screen.
180Hz with 200Hz Overclock
Enjoy smooth gameplay at up to 180Hz, with an optional 200Hz overclocked mode through DisplayPort when supported by the system and configured correctly.
1ms GtG Response Time
The advertised 1ms grey-to-grey response time is available in Faster mode, helping reduce pixel transition blur during fast-moving gameplay.
AMD FreeSync and G-SYNC Compatible
Adaptive sync technology helps coordinate the display refresh rate with a compatible graphics card to reduce screen tearing and stuttering.
HDR10 and sRGB 99%
HDR10 support enables compatible HDR input, while typical 99% sRGB coverage supports vibrant everyday gaming, entertainment and general content creation.
Ergonomic Stand
Adjust the height, tilt and pivot to find a comfortable viewing position. VESA 100 × 100mm mounting support also allows compatible monitor arms and wall mounts.
Fast and Fluid Gaming Performance
The 180Hz native refresh rate displays more frames per second than a conventional 60Hz monitor, making motion appear smoother when your PC can deliver sufficiently high frame rates. For supported setups, the optional 200Hz overclocked mode provides an additional refresh-rate option.
To use the 200Hz overclocked mode, LG specifies a graphics card supporting DisplayPort 1.4 and a suitable DisplayPort 1.4 cable. The feature must be enabled through the monitor's settings, and system compatibility can affect the available modes.
Responsive Visuals with IPS Technology
The IPS panel combines wide 178-degree horizontal and vertical viewing angles with a typical brightness of 300 cd/m² and a typical contrast ratio of 1000:1. Its QHD resolution is well suited to detailed game environments, maps, interfaces and everyday desktop tasks.
Typical sRGB coverage of 99% makes the monitor suitable for general content creation and web-oriented work. For colour-critical professional applications, calibration and a workflow-specific display may still be necessary.
Adaptive Sync for Smoother Gameplay
AMD FreeSync and NVIDIA G-SYNC Compatible support help reduce screen tearing and stuttering when the monitor and graphics card are configured to use compatible variable-refresh-rate features. Performance depends on the GPU, connection, driver and game settings.
These technologies are especially useful when frame rates fluctuate during demanding games, helping maintain a more consistent visual experience within the supported operating range.
Gaming Features and Display Controls
- Black Stabilizer: Adjusts visibility in darker game scenes to help reveal details in shadowed areas.
- Dynamic Action Sync: Helps reduce display processing delay for more immediate-feeling gameplay.
- Crosshair: Adds an on-screen aiming marker for supported gaming scenarios.
- FPS Counter: Displays a frame-rate counter on screen.

- Reader Mode and Flicker Safe: Offer viewing options for reading and everyday desktop use.
- Auto Input Switch: Helps switch inputs when supported connected devices become active.
Connectivity and Setup
The monitor provides two HDMI inputs and one DisplayPort 1.4 input, allowing you to connect a gaming PC and compatible additional devices. A three-pole headphone output is available for audio from a connected source.
For the highest refresh-rate options, use a compatible DisplayPort connection and cable. The actual refresh rate available over each connection depends on the source device, output capabilities and selected display settings.
