Product information

Description

The 39-inch WQHD (3440x1440) UltraWide OLED monitor delivers a wider 21:9 viewing area for immersive gaming and multimedia. With deep blacks, vivid colors and high peak brightness enabled by LG WOLED and MLA+ technology, this curved 800R display combines a fast 240Hz refresh rate and a 0.03ms (GtG) response for fluid motion and reduced ghosting. Built-in features include DisplayHDR True Black 400, wide DCI-P3 color coverage, USB-C with 65W power delivery, ClearMR-certified motion clarity, and integrated audio with DTS Headphone:X and dual 7W speakers. The monitor’s L-stand and slim four-sided bezels create a compact, adjustable setup for desktop use.

Advantages

This UltraWide OLED provides deeper blacks and realistic colors with VESA DisplayHDR True Black 400 and a 1.5M contrast ratio, supporting DCI-P3 98.5% for accurate color reproduction. MLA+ boosts SDR brightness (typical 275 cd/m², peak up to 1300 nits) for clearer images in bright rooms. The 21:9 800R curved screen expands the field of view for more immersive gameplay while maintaining consistent viewing angles. Fast response (0.03ms GtG) and 240Hz refresh reduce motion blur and input delay, and adaptive sync compatibility (NVIDIA G-SYNC Compatible, VESA AdaptiveSync, AMD FreeSync Premium Pro) ensures tear-free output. Additional conveniences include USB-C power delivery up to 65W, on-screen OLED protection controls, and an uncluttered adjustable L-stand design.

How to use

Place the monitor on a stable desk and adjust height, tilt and swivel for a comfortable centered viewing position that aligns with the 800R curvature. Connect your PC or console via HDMI 2.1 or DisplayPort 1.4 for 240Hz WQHD performance; use the USB-C port to connect a laptop and supply up to 65W power. Enable adaptive sync in your graphics settings to minimize tearing and set the refresh rate to 240Hz. Use the on-screen display to adjust brightness, enable OLED protection settings to reduce the risk of image retention, and configure gaming features such as low latency, Black Stabilizer, crosshair and FPS counter as needed.

Recommendations

For best results, use HDMI 2.1 or DisplayPort 1.4 with a compatible GPU to achieve 3440x1440 at 240Hz, enable adaptive sync to prevent tearing, and activate OLED protection options in the OSD when the monitor will display static images for extended periods.
