Release year20262023
Panel27-inch IPS; 3840 × 2160; 16:9

IPS panels offer wide viewing angles and consistent colour; black level stays behind OLED and VA panels.

LG		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
Pixel densityPixel pitch 0.1554 mm (about 163 ppi)

A small pixel pitch makes text sharper; 4K at 27 inches makes interface elements smaller.

LG		—
Refresh rate180 Hz at 4K; 360 Hz at Full HD with Dual Mode

Dual Mode lowers the resolution to Full HD to allow a higher refresh rate; the image is less sharp in that mode.

LG		—
Response time1 ms GtG (at the Faster setting)

LG gives this figure for the fastest response time setting; it gives no figure for other settings.

LG		—
Brightness and contrastTypical 400 cd/m² (minimum 320); contrast 1000:1

1000:1 contrast is typical for IPS; blacks can look grey in a dark room.

LG		—
HDRHDR10; VESA DisplayHDR 400

DisplayHDR 400 is VESA’s lowest HDR certification tier; HDR content plays but bright highlights stay limited.

LG		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
ColourDCI-P3 95% (typical, CIE1976); 1.07 billion colours; factory calibration

DCI-P3 coverage describes how much of the wide colour space used in films and games can be shown.

LG		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
SyncNVIDIA G-Sync Compatible, AMD FreeSync, VESA Adaptive-Sync

Variable refresh matches the screen to the graphics card’s frame rate, reducing tearing and stutter.

LG		—
Video inputs2 HDMI 2.1, 1 DisplayPort 1.4 (DSC)

DSC uses visually lossless compression to fit a 4K 180 Hz signal into DisplayPort 1.4 bandwidth.

LG		—
USB1 USB 3.0 upstream, 2 USB 3.0 downstream; no USB-C

The USB ports act as a hub; no USB-C connection for video or charging is listed.

LG		—
AudioHeadphone out; DTS Headphone:X; no built-in speakers listed

Headphones or external speakers are needed for sound.

LG		—
StandHeight, tilt, swivel and pivot adjustment; VESA 100 × 100

Pivot lets the screen be used in portrait; VESA 100 × 100 fits standard monitor arms.

LG		—
PowerExternal adapter; 100–240 V; under 0.5 W in sleep

The external adapter keeps the monitor thinner but takes extra space on the desk.

LG		External adapter, 19 V / 3.42 A (65 W); 50 W typical, 55 W max; under 0.5 W in sleep LG
Size and weightWith stand 24.2 × 21.0 × 8.7 in (raised), 16.3 lb (about 7.4 kg); without stand 24.2 × 14.6 × 2.0 in, 10.8 lb (about 4.9 kg)

Use the weight without the stand when choosing a monitor arm.

LG		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
In the boxDisplayPort and HDMI cables

No USB upstream cable is listed.

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
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
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
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
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.
