The LG UltraFine 27U730A-B is the monitor for professionals who refuse to compromise. With a stunning 27" 4K UHD IPS display, a single USB-C cable to power, charge, and connect your laptop, and a fully adjustable ergonomic stand, it transforms any desk into a precision workstation — whether you're editing footage, managing complex layouts, or simply getting more done with fewer cables.
Key Features
- 4K UHD (3840×2160) IPS Display: Four times the resolution of Full HD on an IPS panel, delivering accurate, consistent colour across the entire screen — edge to edge, without colour shift at any viewing angle.
- USB-C with 90W Power Delivery: One cable handles display output, high-speed data transfer, and up to 90W charging for your laptop simultaneously. Plug in once and work — no power brick needed on your desk.
- HDR10 & 90% DCI-P3 Colour Gamut: Covers a wider colour space than standard sRGB monitors, making it ideal for photo editing, video grading, and creative work that demands accurate colour reproduction.
- Fully Ergonomic Stand: Adjust height (150mm range), tilt (-5° to +21°), swivel (±45°), and pivot (90° rotation into portrait mode) to find your perfect working position. VESA 100×100mm compatible for arm mounting.
- Built-in Stereo Speakers with Waves MaxxAudio®: Dual 5W speakers with MaxxAudio processing deliver rich, full audio for calls, media, and presentations — no need for separate desktop speakers.
- 3-Side Virtually Borderless Design: A clean, minimal bezel on three sides maximises your screen real estate and creates a seamless look whether you're running a single monitor or building a multi-display setup.
- LG Switch App: Split your screen into 11 layout options, customise image presets, and launch your video call platform in one click — all manageable from software on your PC or Mac.
