## Long description

Superfast 480Hz OLED with DP 2.1 and ClearMR 21000. LG UltraGear™ OLED monitor combines Micro Lens Array+ (MLA+) technology with a brighter WOLED panel that reaches a peak brightness of 1300 nits and supports an ultra-high 480Hz refresh rate and 0.03ms (GtG) response time. The display offers deep blacks, wide DCI‑P3 colour gamut and VESA DisplayHDR True Black 400 certification for precise, vivid images across dark and bright scenes. Multiple inputs including DisplayPort 2.1 and dual HDMI 2.1 ensure compatibility with next‑generation GPUs and consoles, while a compact four‑sided near‑borderless design and adjustable stand provide flexible desk placement.
Advantages
High refresh rate and minimal response deliver smooth, low‑latency visuals for competitive gaming. MLA+ and WOLED bring improved SDR brightness (up to 37.5% gain) and accurate colour reproduction (Delta E ≤ 2) for faithful images. DisplayPort 2.1 support enables 480Hz at QHD with future GPUs, while HDMI 2.1 x2 offers direct console connectivity. ClearMR 21000 certification confirms exceptional motion clarity, and anti‑glare, low reflection and UL Platinum low blue light certification offer comfortable viewing for long sessions. The monitor also includes hardware calibration support via LG Calibration Studio and user‑friendly on‑screen controls.

How to use
Connect the monitor via DisplayPort 2.1 or HDMI 2.1 depending on your source. For the highest refresh rates at QHD use a compatible DP 2.1 GPU connection. Use the on‑screen gaming GUI or LG Switch to adjust display presets, register user shortcuts and switch between 27" and 24" screen modes. For accurate colour work, run hardware calibration with LG Calibration Studio. To maximise brightness, disable Smart Energy Saving in the monitor menu.
Recommendations
To reduce the risk of image retention or burn‑in, enable OLED Screen Move, Screen Saver and Image Cleaning features; avoid leaving static high‑contrast images on screen for extended periods. For optimal motion clarity, ensure your system and cables support DP 2.1 or HDMI 2.1 bandwidth required for 480Hz operation.
