Release year20242023
Panel26.5-inch (67.3 cm) OLED; 2560 × 1440; 16:9; 0.2292 mm pixel pitch

Although sold in the 27-inch class, the viewable diagonal is 26.5 inches. OLED lights each pixel itself, so there is no backlight bleed.

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
Speed240 Hz; 0.03 ms (GtG) response time

GtG is the time a pixel takes to change from one grey level to another; lower values reduce motion blur.

LG		—
Brightness and contrast275 nits typical, 250 nits minimum; contrast 1,500,000:1 typical, 1,200,000:1 minimum

LG quotes 275 nits for a full-white screen (100% average picture level); small bright areas can be brighter.

LG		—
ColourDCI-P3 98.5% typical (90% minimum, CIE1976); 1.07 billion colours; factory calibrated; hardware calibration ready

A printed calibration report is included. Hardware calibration uses LG Calibration Studio with a compatible meter.

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
HDR and syncHDR10; VESA DisplayHDR True Black 400; 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.

ConnectionsHDMI 2.1; 1 × DisplayPort 1.4 (DSC); USB 3.0 (1 upstream, 2 downstream); optical audio out (SPDIF); 4-pole headphone out, DTS Headphone:X

DSC compression helps carry QHD at 240 Hz over DisplayPort 1.4. There is no USB-C video input.

LG		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.

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
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
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.
