| Panel | 27-inch (68.5 cm) IPS, 3840 × 2160, 16:9; anti-glare surface At 27 inches, 4K means high pixel density; text and detail look very sharp, though Windows usually needs scaling. IPS panels offer wide viewing angles and good colour, but blacks are not as deep as OLED. 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 time | 144 Hz; 1 ms (GtG, Faster mode) LG notes that 1 ms is only achieved with Game Adjust → Response Time → Faster. 144 Hz requires a graphics card with DisplayPort 1.4 (DSC) or HDMI 2.1. LG | 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.

| Contrast and viewing angle | 1000:1 typical (700:1 minimum); 178° / 178° 1000:1 is ordinary for IPS: blacks can look grey in a dark room. No local dimming is listed. LG | — |

| Colour | DCI-P3 95% typical (90% minimum, CIE1976); 10-bit (8-bit + FRC), 1.07 billion colours; hardware calibration ready 8-bit + FRC imitates 10-bit gradations with rapid dithering; usually invisible to the eye. Hardware calibration writes settings to the monitor’s own memory. 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.

| HDR | HDR10; VESA DisplayHDR 400; HDR Effect DisplayHDR 400 is the entry tier of HDR certification; without local dimming, the bright-to-dark range of HDR content stays limited. HDR Effect is a picture mode that makes SDR content look more HDR-like. LG | — |
|---|
| Adaptive sync | NVIDIA G-SYNC Compatible; AMD FreeSync Premium; VRR up to 144 Hz Matches the monitor’s refresh to the game’s frame rate, reducing tearing and stutter. According to LG, VRR needs a graphics card with DisplayPort 1.4 (DSC) or HDMI 2.1. LG | — |

| Connections | 2 × HDMI (2.1), 1 × DisplayPort 1.4 (DSC); USB 3.0 upstream 1, downstream 2; 4-pole headphone out (audio + mic), DTS Headphone:X DSC (Display Stream Compression) compresses the 4K 144 Hz signal, which exceeds DisplayPort 1.4 bandwidth, with no visible loss. There is no USB-C input and no built-in speakers are listed. 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 |
|---|
| Gaming features | Black Stabilizer, Dynamic Action Sync, Crosshair, FPS Counter, User Defined Key; Hexagon RGB LED lighting Black Stabilizer brightens dark areas so opponents in shadow are visible; Crosshair places a fixed aiming point at screen centre. Crosshair is unavailable while FPS Counter is on. LG | 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 |

| Stand and mounting | Height, tilt, pivot; detachable base; cable holder and mouse cable holder Per LG Canada dimensions, height with stand ranges from 467.7 to 577.7 mm, so about 110 mm of height adjustment. Pivot turns the screen to portrait; swivel is not listed. LG | Tilt, height and swivel adjustment; 100 × 100 mm VESA wall mount LG |
|---|
| Power | External adapter, 19 V / 3.42 A (65 W); 50 W typical, 55 W max; 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 613.5 × 467.7–577.7 × 253.7 mm, 6.4 kg; without stand 613.5 × 371.6 × 51.3 mm, 4.5 kg 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 |
|---|
| 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 |
|---|
| Lighting and control | — | Hexagon RGB lighting on the back; remote control; OnScreen Control and Dual Controller software LG |
