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		49-inch QD-OLED; 5120 × 1440 (DQHD), 32:9; 1800R curve

The 32:9 ratio gives a workspace equivalent to two 27-inch 1440p monitors side by side. The 1800R curve keeps the edges closer to the eyes.

MSI
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		—
Brightness300 nits (typical)

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

Samsung		—
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.

Colour99% DCI-P3 · 1 billion colours

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

Refresh and response—144 Hz (adaptive range 48–144 Hz); 0.03 ms (GtG)

Adaptive sync prevents tearing while the frame rate stays between 48 and 144. Reaching 144 fps at full resolution needs a very powerful graphics card.

MSI
Brightness and contrast—Typical SDR 250 nits; 1,500,000:1; DisplayHDR True Black 400

True Black 400 is the OLED-class certification for very low black level and 400-nit HDR brightness.

MSI
