Specification	LG UltraGear OLED 45GR95QE-B	LG UltraGear 27GP750-B
Release year	2023	2021
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	27-inch (68.5 cm) IPS; 1920 × 1080; 16:9; pixel pitch 0.3108 mm A 0.31 mm pixel pitch works out to about 82 ppi at 27 inches. Viewing angles are 178°/178°. 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	400 cd/m² typical (minimum 320); 1000:1 typical contrast (minimum 700:1) 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	2 × HDMI; 1 × DisplayPort 1.4; 3.5 mm headphone out A DisplayPort cable is in the box. There are no built-in speakers or USB hub. LG
Stand and mounting	Tilt, height and swivel adjustment; 100 × 100 mm VESA wall mount LG	Height, tilt and pivot adjustment; VESA 100 × 100 Height adjustment changes the overall height with the stand between 465.9 and 575.9 mm. 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	External adapter; 45 W typical, 48 W maximum; under 0.5 W in sleep LG
In the box	DisplayPort cable, USB A-to-B cable, remote control Box contents can vary by country. LG	—
Refresh and response	—	Up to 240 Hz; 1 ms (GtG, in Faster mode) LG quotes 1 ms for grey-to-grey transitions at the fastest overdrive setting. Dynamic Action Sync aims to reduce input lag, and Black Stabilizer brings out detail in dark scenes. LG
Variable refresh	—	NVIDIA G-SYNC Compatible; AMD FreeSync Premium Variable refresh matches the monitor’s refresh rate to the graphics card’s frame rate to reduce tearing and stutter. LG
Colour and HDR	—	99% sRGB typical (minimum 95%, CIE1931); 16.7 million colours; HDR10; factory calibrated HDR10 signals are accepted; LG lists no DisplayHDR certification in the spec table, and typical brightness is 400 cd/m². LG
Size and weight	—	Without stand 614.2 × 364.8 × 51.7 mm, 3.9 kg; with stand 6 kg LG
