Panel26.5-inch (67.3 cm) OLED; 2560 × 1440; 16:9; 0.2292 mm pixel pitch

Although sold in the 27-inch class, the viewable diagonal is 26.5 inches. OLED lights each pixel itself, so there is no backlight bleed.

LG		44.5-inch (113 cm) OLED, 800R curve; 3440 × 1440 (21:9); 0.303 mm pixel pitch

800R means the screen curves like part of a circle with an 800 mm radius, wrapping the edges around your view. At 45 inches, 1440p gives low pixel density: up close, text and fine detail look less sharp than on a 27-inch 1440p screen.

LG
Speed240 Hz; 0.03 ms (GtG) response time

GtG is the time a pixel takes to change from one grey level to another; lower values reduce motion blur.

Brightness and contrast275 nits typical, 250 nits minimum; contrast 1,500,000:1 typical, 1,200,000:1 minimum

LG quotes 275 nits for a full-white screen (100% average picture level); small bright areas can be brighter.

LG		200 cd/m² typical (160 minimum); typical contrast 1,500,000:1

LG’s typical brightness refers to a full-screen SDR image; with self-emissive OLED pixels black switches fully off, giving very high contrast.

LG
ColourDCI-P3 98.5% typical (90% minimum, CIE1976); 1.07 billion colours; factory calibrated; hardware calibration ready

A printed calibration report is included. Hardware calibration uses LG Calibration Studio with a compatible meter.

LG		DCI-P3 98.5% (typical, CIE1976), 90% minimum; 1.07 billion colours; factory calibrated; hardware calibration ready

Hardware calibration writes settings into the monitor itself through LG Calibration Studio, so the colour setup stays with the monitor even if the computer changes.

LG
HDR and syncHDR10; VESA DisplayHDR True Black 400; NVIDIA G-SYNC Compatible; AMD FreeSync Premium Pro; VRR

Variable refresh rate matches the monitor to the graphics card’s frame rate, reducing tearing and stutter.

LG		HDR10, HDR effect; NVIDIA G-SYNC Compatible, AMD FreeSync Premium, VRR

G-SYNC Compatible and FreeSync Premium match the refresh rate to the graphics card’s frame rate to reduce tearing and stutter. HDR effect is a picture mode that adds HDR-like contrast to SDR content in software; it is not real HDR.

LG
ConnectionsHDMI 2.1; 1 × DisplayPort 1.4 (DSC); USB 3.0 (1 upstream, 2 downstream); optical audio out (SPDIF); 4-pole headphone out, DTS Headphone:X

DSC compression helps carry QHD at 240 Hz over DisplayPort 1.4. There is no USB-C video input.

LG		2 × HDMI, 1 × DisplayPort 1.4 (DSC), 1 × USB 3.0 upstream, 2 × USB 3.0 downstream, optical digital audio out (S/PDIF), 4-pole headphone out (sound + mic)

DSC (Display Stream Compression) compresses high-bandwidth signals such as 3440 × 1440 at 240 Hz over DisplayPort 1.4 without visible loss. With the USB upstream connected, the monitor’s USB-A ports act as a hub for the computer. A headset with a mic plugs into the 4-pole jack; DTS Headphone:X adds virtual surround. No built-in speakers are listed.

LG
Refresh rate and response time—240 Hz; 0.03 ms (GtG)

240 Hz shows very smooth motion when a game approaches 240 frames per second, which needs a powerful graphics card. 0.03 ms grey-to-grey describes the fast transition of OLED pixels; it is not total input lag.

LG
Gaming features—Black Stabilizer, Dynamic Action Sync, crosshair, FPS counter, user-defined key, auto input switch

Black Stabilizer brightens detail in dark scenes; Dynamic Action Sync is a mode that reduces input lag.

LG
PiP—Picture-in-picture (PiP)

PiP shows a second input in a small window over the main picture, for example a PC and a console at the same time. LG does not list PbP (side-by-side split) for this model.

Lighting and control—Hexagon RGB lighting on the back; remote control; OnScreen Control and Dual Controller software LG
