Panel26.5-inch WOLED; 2560 × 1440 (16:9); 0.229 mm pixel pitch; anti-glare surface

WOLED is LG Display’s panel type using a white OLED layer with colour filters; each pixel makes its own light, so blacks go fully dark. Long-lasting static images raise the risk of burn-in.

ASUS		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
Refresh rate and response240 Hz (DisplayPort); 120 Hz over HDMI; 0.03 ms (GtG)

240 Hz is only available through the DisplayPort input; ASUS’s signal table limits the HDMI inputs to 120 Hz. For PC games above 120 Hz, use a DisplayPort cable.

ASUS		—
Brightness and contrastHDR peak 1,000 cd/m²; contrast 1,500,000:1; 10-bit (1.07 billion colours)

Peak brightness applies to a small part of the screen; with a full white screen brightness drops noticeably. ASUS notes peak brightness may vary with colour pre-calibration.

ASUS		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 99%; sRGB 135%; factory pre-calibration report ASUSDCI-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
HDRHDR10

Dolby Vision and HDR10+ support are not listed.

ASUS		—
Variable refreshVESA AdaptiveSync Display 240Hz; AMD FreeSync Premium; G-SYNC Compatible

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

ASUS		—
Inputs1 × DisplayPort 1.4 DSC; 2 × HDMI 2.0; headphone jack; 2 × USB 3.2 Gen 1 Type-A hub

DSC (Display Stream Compression) compresses the signal without visible loss so DisplayPort 1.4 has enough bandwidth for high refresh rates. There are no speakers and no USB-C input.

OLED care and warrantyASUS OLED Care; 2-year warranty (including panel burn-in)

The warranty also covers panel burn-in; terms may vary by region.

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
HDR and sync—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
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.

LG
Connections—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
Lighting and control—Hexagon RGB lighting on the back; remote control; OnScreen Control and Dual Controller software LG
In the box—DisplayPort cable, USB A-to-B cable, remote control
