Panel27-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		26.5-inch (27-inch class) QD-OLED, 16:9, anti-reflection surface

QD-OLED pairs self-emitting pixels with a quantum-dot colour layer; each pixel switches off individually, so blacks are fully dark.

ASUS
Refresh rateUp to 500 Hz

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

Samsung		—
Response time0.03 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		0.03 ms (GtG)

This is the grey-to-grey pixel transition time, not total input lag.

ASUS
Brightness300 nits (typical)

The typical figure is for full-screen SDR; small bright areas go higher in HDR.

Samsung		1000 cd/m² HDR peak

ASUS notes peak brightness may vary with colour pre-calibration; the peak is reached on a small screen area.

ASUS
HDRDisplayHDR 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		HDR10; VESA DisplayHDR 400 True Black ASUS
Colour99% DCI-P3 · 1 billion colours

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

Samsung		99% DCI-P3, 145% sRGB; ΔE < 2; 10-bit

Factory calibration (ΔE < 2) means colours are set close enough to target that differences are hard to see.

Samsung		FreeSync Premium Pro, G-SYNC Compatible; VESA AdaptiveSync Display 240 Hz

Variable refresh matches the screen's rate to the graphics card's frame rate, reducing tearing and stutter.
