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		26.5-inch WOLED; anti-glare surface

WOLED uses a white OLED layer with colour filters; each pixel makes its own light, so blacks switch fully off.

ASUS
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.

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

Warranty length varies by country.

Burn-in is when long-static images leave a mark on an OLED panel; the OLED Care features aim to reduce it.

ASUS
Resolution—2560 × 1440, 16:9 ASUS
Refresh rate—Up to 480 Hz

480 Hz improves motion clarity in fast games; reaching it also needs the graphics card to render close to 480 frames.

ASUS
Response time—0.03 ms (GtG)

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

ASUS
Brightness and contrast—HDR peak 1,300 cd/m²; contrast 1,500,000:1 (typical)

The peak figure applies to a small part of the screen; ASUS notes that peak brightness may vary with colour pre-calibration.

ASUS
Colour—99% DCI-P3, 135% sRGB; 10-bit; ΔE < 2

A colour pre-calibration report is included in the box.

ASUS
HDR and certifications—HDR10; VESA DisplayHDR 400 True Black ASUS

Variable refresh matches the monitor’s rate to the graphics card’s frame rate to prevent tearing.

ASUS
Video inputs—1 × DisplayPort 1.4 (DSC), 2 × HDMI 2.1 (FRL)

DSC compresses the signal in a way considered visually lossless so that 1440p 480 Hz fits within DisplayPort 1.4 bandwidth.
