Panel26.5-inch flat QD-OLED; 3840 × 2160; 10-bit (1.07 billion colours)

In QD-OLED, light from a blue OLED layer is converted to red and green by quantum dots; because each pixel emits its own light, blacks switch off completely. 4K in the 27-inch class gives very sharp text at about 166 ppi.

MSI
33.94-inch WOLED; 3440 × 1440; 21:9; 800R curve; anti-glare (matte) surface

800R means the screen curves like an arc of a circle with an 800 mm radius. Pixel pitch is 0.231 mm.

ASUS
Refresh and response240 Hz (adaptive range 48–240 Hz); 0.03 ms GtG

4K 240 Hz is reached over DisplayPort 2.1a or HDMI 2.1. 0.03 ms is pixel transition time, not total input lag.

Adaptive syncG-SYNC Compatible; AMD FreeSync Premium Pro

Matching refresh rate to the GPU frame rate reduces tearing and stutter.

Brightness and HDRSDR 250 nits; HDR 450 nits at 10% APL, 1000 nits peak at 3% APL; DisplayHDR True Black 400

1000 nits is reached only when a very small part of the screen is bright; OLED brightness drops markedly on a full white screen. True Black 400 is the VESA tier for OLEDs that also measures black level.

MSI
1300 cd/m² HDR peak brightness; HDR10; VESA DisplayHDR 400 True Black

ASUS gives this figure, asterisked, as peak HDR brightness; it is not sustained full-screen brightness.

ASUS
Colour and contrastDCI-P3 99%, Adobe RGB 98%, sRGB 138% (CIE 1976); 1,500,000:1 typical contrast

138% of sRGB means the panel can oversaturate standard content; use the sRGB mode for accurate colour.

Video inputs1 × DisplayPort 2.1a (UHBR20); 2 × HDMI 2.1 (UHD 240 Hz); 1 × USB-C (DP Alt Mode, 98 W PD)

UHBR20 offers 80 Gbit/s, enough to carry 4K 240 Hz 10-bit without compression, provided the GPU also supports DP 2.1 UHBR20. USB-C delivers video, data and up to 98 W laptop charging over one cable.

MSI
1 × DisplayPort 1.4 (DSC); 2 × HDMI 2.1 (FRL); 1 × USB-C (DP Alt Mode, 90 W power)

The USB-C input can take video from a laptop over one cable while charging it at up to 90 W. All three inputs support vertical frequencies up to 240 Hz.

ASUS
USB and audio2 × USB-A 5 Gbit/s; 1 × USB-B 5 Gbit/s (upstream); headphone out; no built-in speakers MSI—
