Release year20262025
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 QD-OLED · 2560 × 1440 (QHD), 16:9

QD-OLED puts a quantum-dot colour converter over a blue-emitting OLED layer; each pixel produces its own light.

Samsung
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		Up to 500 Hz

Samsung notes the maximum may vary by input source; reaching 500 Hz requires a source that can output it.

Samsung
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		0.03 ms (GtG)

GtG is the time a pixel takes to change from one grey level to another; lower values mean less smearing in motion.

Samsung
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		DisplayHDR True Black 500 · HDR10+ Gaming · 1000 nits typical, 800 nits minimum at 3% window (peak brightness set to High)

A 3% window means only a small part of the screen is lit; brightness drops below this in large bright scenes.

Samsung
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		99% DCI-P3 · 1 billion colours

DCI-P3 is the wide colour space used for cinema and HDR content.

Samsung
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.
