Brightness450 nits typical; 600 nits peak; HDR 600 Dell—
Rated contrast3000:1 native contrast

IPS Black targets darker blacks than conventional IPS; it does not give per-pixel black like OLED or local-dimming displays.

Dell		—
Colour1.07 billion colours; 100% sRGB and Rec.709; 99% DCI-P3 and Display P3; factory calibration average ΔE < 1.5 DellDCI-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.

FirmwareM2T102 (A01, 19 August 2025)

Dell says it targets wake-from-sleep, USB dropping to 480 Mbit/s on MacBooks, auto brightness/colour temperature sensing and daisy-chained displays not waking.

Dell		—
Panel—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 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
Brightness and contrast—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
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
Stand and mounting—Tilt, height and swivel adjustment; 100 × 100 mm VESA wall mount LG
Lighting and control—Hexagon RGB lighting on the back; remote control; OnScreen Control and Dual Controller software LG
Power—External adapter; 100–240 V; 129 W typical, 160 W max, under 0.5 W in sleep LG
