Specification	LG UltraGear 45GX950A-B	LG UltraGear OLED 45GR95QE-B
Release year	2025	2023
Panel	44.5-inch WOLED, 21:9, 800R curve; 5120 × 2160 (5K2K), 0.2035 mm pixel pitch (about 125 ppi); MLA+ 800R means the screen curves along a circle with an 80 cm radius, so the edges sit closer to the eyes. MLA+ (micro lens array) directs OLED pixel light forward to raise brightness. 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
Refresh rate and response	165 Hz at 5K2K; 330 Hz at WFHD with VESA-certified Dual-Mode; 0.03 ms (GtG) Dual-Mode doubles the refresh rate by lowering the resolution: 330 Hz for fast competitive games, 5K2K at 165 Hz for detailed games. LG	—
Brightness and HDR	275 cd/m² typical (minimum 250); HDR10, VESA DisplayHDR True Black 400; DCI-P3 98.5%; 10-bit; contrast 1,500,000:1 (typical) DisplayHDR True Black 400 is VESA’s certification for screens that can turn black fully off, such as OLED, and requires 400 nits peak brightness. LG	—
Sync	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	—
Inputs	2 × HDMI, 1 × DisplayPort 2.1 (DSC), 1 × USB-C (5120 × 2160 at 165 Hz, data, 90 W power); 2 × USB 3.0 downstream; 4-pole headphone/mic DSC compresses the image visually losslessly so high resolution and refresh rate fit through one cable. USB-C gives a laptop video, data and 90 W charging over one cable. LG notes NVIDIA released a driver in April 2025 that fixed screen blackouts seen over DisplayPort. LG	—
PiP and PbP	PIP and 2-source PBP PiP shows one source in a small window, and PbP splits the screen to show two sources side by side, for example a computer and a game console at once. LG	—
Audio	10 W × 2 stereo speakers, DTS Headphone:X LG	—
Stand and mounting	Tilt, height and swivel adjustment; 100 × 100 mm VESA mounting LG	Tilt, height and swivel adjustment; 100 × 100 mm VESA wall mount LG
Power	External adapter (20 V / 18 A); under 0.5 W in sleep LG	External adapter; 100–240 V; 129 W typical, 160 W max, under 0.5 W in sleep LG
Size and weight	With stand 991.6 × 545.6–665.6 × 342 mm, 14 kg; without stand 991.6 × 460.7 × 225.5 mm, 9.4 kg 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
Colour	—	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 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 Box contents can vary by country. LG
