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		26.5-inch (67.32 cm) OLED, 2560 × 1440 (16:9); 0.2292 mm pixel pitch; 1.07 billion colours

Because self-lit OLED pixels can switch fully off, blacks are true black; LG gives typical contrast as 1,500,000:1. 1.07 billion colours corresponds to 10-bit colour depth.

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		—
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		—
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		2 × HDMI 2.1, 1 × DisplayPort 1.4 (DSC)

DSC (Display Stream Compression) uses visually lossless compression to fit a 1440p 240 Hz signal within DisplayPort 1.4 bandwidth. The HDMI 2.1 inputs support VRR on consoles. There is no USB-C video input.

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, AC 100–240 V; typical 74 W, maximum 94 W; 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		Without stand 604.4 × 350.6 × 45.3 mm, 5.05 kg; with stand 604.4 × 464.4–574.4 × 258 mm, 7.35 kg LG
In the boxDisplayPort and HDMI cables

No USB upstream cable is listed.

LG		—
Refresh rate and response time—240 Hz; 0.03 ms (GtG)

240 Hz shows 240 frames per second, making motion smoother and less blurred in fast games; this needs a graphics card producing 240 fps and a DisplayPort or HDMI 2.1 connection. GtG is the time a pixel takes to change from one grey level to another.

LG
Brightness—Typical 200 cd/m², minimum 160 cd/m²

These are full-screen SDR figures; small HDR highlights can be brighter. LG does not give a peak HDR figure in the spec table.

LG
Colour and HDR—98.5% DCI-P3 (typical), 90% (minimum); HDR10; factory calibrated; hardware calibration ready

Hardware calibration uses LG Calibration Studio and a compatible colorimeter to adjust the monitor’s own colour tables. No VESA DisplayHDR certification is listed.

LG
Adaptive sync and gaming—NVIDIA G-SYNC Compatible, AMD FreeSync Premium, VRR; Black Stabiliser, Dynamic Action Sync, crosshair, FPS counter

Adaptive sync matches the monitor’s refresh to the graphics card’s frame rate to reduce tearing and stutter. Dynamic Action Sync is meant to reduce input lag.

LG
USB and audio—1 × USB 3.0 upstream, 2 × USB 3.0 downstream; 4-pole headphone output (sound + mic) with DTS Headphone:X; optical digital audio out (S/PDIF)

There are no built-in speakers. DTS Headphone:X gives virtual 3D audio over headphones.

LG
Stand and mounting—Tilt, height, swivel and pivot adjustment; VESA 100 × 100 LG
Lighting and remote—Hexagon Lighting on the back; remote control included LG
