Brightness450 nits typical; 600 nits peak; HDR 600 Dell—
Rated contrast3000:1 native contrast

IPS Black targets darker blacks than conventional IPS; it does not give per-pixel black like OLED or local-dimming displays.

Colour1.07 billion colours; 100% sRGB and Rec.709; 99% DCI-P3 and Display P3; factory calibration average ΔE < 1.5 DellDCI-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.

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
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
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.

LG
Power—External adapter, 19 V / 3.42 A (65 W); 50 W typical, 55 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
