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		120 Hz; 48–120 Hz variable refresh

Variable refresh works over HDMI 2.1; dynamic refresh rate (DRR) over DisplayPort is also listed for Windows.

Dell
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		5 ms GtG (fast mode); 8 ms GtG

Pixel transition specification, not total input lag.

Dell
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		1.07 billion colours; 100% sRGB and Rec.709; 99% DCI-P3 and Display P3; factory calibration average ΔE < 1.5 Dell
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		1 × HDMI 2.1 (4K 120 Hz, VRR); 1 × DisplayPort 1.4 in (DSC, HDCP 2.2); 1 × DisplayPort out Dell
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		3.5 mm analogue line-out; no built-in speakers Dell
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		150 mm height; −5°/+21° tilt; ±45° swivel; ±90° pivot Dell
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.
