Panel31.5-inch flat VA (vertical alignment) panel, LED edge backlight; 16:9, 3840 × 2160 (4K UHD), 139 ppi; anti-glare 3H-hardness surface

Dell lists 3000:1 contrast and 178°/178° viewing angles for this VA panel; the viewing-angle figure does not show at what angle colour and contrast start to shift.

Dell		31.5-inch flat QD-OLED; 3840 × 2160; 0.1814 mm pixel pitch; anti-reflection surface

QD-OLED converts blue OLED light to red and green with quantum dots; because each pixel makes its own light, blacks can switch fully off. 4K at 32 inches gives roughly 140 ppi.

MSI
Refresh rate and response time120 Hz (48–120 Hz vertical frequency); 4 ms GtG (Extreme), 5 ms GtG (Fast), 8 ms GtG (Normal); AMD FreeSync Premium

120 Hz at 4K is available over both HDMI 2.1 and DisplayPort 1.4; the source must also output 4K at 120 Hz. FreeSync Premium matches the refresh to the game’s frame rate within 48–120 Hz to prevent tearing; AMD’s tier also includes low framerate compensation (LFC). GtG figures are given for the fastest overdrive mode.

Dell		—
Brightness, contrast and colour300 nits; 3000:1 contrast; 1.07 billion colours; 95% DCI-P3, 99% sRGB; HDR10

HDR10 support means the monitor accepts HDR signals; with 300 nits and edge lighting it carries no DisplayHDR tier. 1.07 billion colours corresponds to 10-bit colour depth.

Dell		—
Connections2 × HDMI 2.1 (FRL, HDR, VRR; up to 4K 120 Hz; HDCP 2.2), 1 × DisplayPort 1.4 (4K 120 Hz, HDR, VRR; HDCP 2.2)

There is no USB-C, USB hub, headphone output or webcam, so a laptop cannot be charged over a single cable. A 1.8 m HDMI cable is in the box.

ComfortView Plus cuts blue light to 35% or less at the hardware level; Dell says this does not affect colour accuracy.

Warranty1-year limited hardware warranty with advanced exchange service in the US

Warranty length varies by country.

Dell		3 years, including panel burn-in

On OLED panels, images left static for long periods can leave a permanent mark (burn-in); MSI covers this risk under warranty. Terms may vary by country.

MSI
Refresh and response—240 Hz (48–240 Hz variable range); 0.03 ms GtG

MSI says 240 Hz at 4K is reachable over DisplayPort 1.4a, HDMI 2.1 and USB-C alike. 0.03 ms is grey-to-grey transition time, not total input lag.

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

DisplayHDR True Black 400 is the VESA class for displays that can produce deep blacks such as OLED; it requires 400-nit small-area brightness and a very low black level. 250 nits is the full-screen SDR figure.

MSI
Colour—10-bit (1.07 billion colours); 99% DCI-P3, 97% Adobe RGB, 138% sRGB

138% sRGB means the gamut extends well beyond sRGB; use the monitor’s sRGB mode so sRGB content does not look oversaturated.

MSI
Adaptive sync—G-SYNC Compatible; AMD FreeSync Premium Pro

Adaptive sync matches the display refresh to the game’s frame rate to reduce tearing and stutter. FreeSync Premium Pro adds a low-latency requirement in HDR.

MSI
Inputs—1 × DisplayPort 1.4a; 2 × HDMI 2.1; 1 × USB-C (DP Alt Mode, 90 W PD); 2 × USB 2.0 Type-A, 1 × USB 2.0 Type-B; headphone out

The USB-C input can carry video and charge a laptop at up to 90 W over a single cable. Display Ninja says the monitor has a built-in KVM; the USB-A ports run at USB 2.0 speed.
