A 27-inch 4K desktop monitor designed for accurate images and comfortable working, the LG UltraFine Monitor helps maintain correct colour checks and a more relaxed posture. Creatives and home office users should notice clearer detail and less neck strain during long sessions. Is the extra resolution and app-led workflow the right upgrade for your setup?

⚡ At a Glance
  • Image Quality: 4K UHD (3840x2160) clarity combined with DCI-P3 90% and HDR10 for richer tones
  • Best for: Photographers, designers and remote workers who need colour accuracy and detail
  • Not ideal for: Gamers who prioritise very high refresh rates and ultra-low latency

A 27-inch IPS panel delivers 3840x2160 detail with HDR10 and a wide 90% DCI-P3 gamut. An ergonomic stand and LG Switch app aid posture and desktop organisation.


Colour-critical work – thanks to DCI-P3 90% and 10-bit support

The panel covers DCI-P3 90% (typical) and supports 10-bit colour depth, enabling finer tonal gradations and a broader visible gamut than standard sRGB. HDR10 handles brighter highlights while preserving shadow detail.

More accurate colour and smoother gradients make photo and video editing more reliable, reducing the need for repeated colour corrections.

Comfortable, adjustable viewing – with height, tilt, swivel and pivot stand

A fully adjustable stand allows height changes, forward and backward tilt, left-right swivel and a 90-degree pivot for portrait orientation. Quick, tool-free adjustments help position the panel at an ergonomically correct viewing angle.

Easier posture management and faster multi-monitor alignment reduce neck and shoulder strain during long sessions.

Streamlined multitasking – with the LG Switch app for window management

LG Switch enables splitting the screen into up to six regions, theme changes, and mapping hotkeys to launch apps or video calls. Window layouts can be saved and recalled for recurring workflows.

Faster window arrangement and one-touch app launching speed up daily tasks, keeping focus on creative work rather than fiddling with windows.
