Overview
A built-in colorimeter is the feature that gives this monitor away. Dell has put a calibration sensor inside a 31.5-inch 4K QD-OLED, which means the panel can re-profile itself rather than drift - and that is a workstation idea, not a gaming one. The rest follows: Thunderbolt 4 at 140 W, a 2.5 GbE network port, Dolby Vision and DisplayHDR 500 True Black, true 10-bit colour with 99% DCI-P3, and 1,500,000:1 contrast at 139 PPI. Refresh reaches 120 Hz with a 0.03 ms response and FreeSync Premium, so it games perfectly well without pretending to be an esports panel. There are no speakers, and OLED burn-in care applies to static desktop work.

HDR & Brightness Reality
This is a professional HDR setup wearing an office badge. Dolby Vision decoding plus DisplayHDR 500 True Black on a QD-OLED panel means both the formats and the black floor are there, and a built-in colorimeter means the colour behind them stays accurate over time rather than drifting away from your profile. Peak brightness is 1000 cd/m2 with 300 cd/m2 full-screen - the usual OLED shape, and the usual condition: control your room lighting and it is superb, sit under a window and it is not.

Frequently Asked Questions
01 What does a built-in colorimeter actually do? +
It measures the panel's own output and corrects it, so colour accuracy holds over months rather than drifting. Normally you would buy a separate calibration device and run it manually - here it is inside the monitor.
02 Why does a monitor have a 2.5 GbE port? +
Because it is designed as a dock. Thunderbolt 4 carries video, data and 140 W of power to a laptop, and the LAN port means that same cable gets you wired networking - no separate dock needed.
03 Is 140 W enough for a workstation laptop? +
For most, yes. 140 W covers high-power laptops that 90 W docks cannot keep charged under load, which is exactly the machine this monitor is aimed at.
04 Should a QD-OLED be my work monitor? +
It is the honest tension. You get contrast and colour no IPS can match, plus a colorimeter to keep it accurate - but static toolbars are what OLED dislikes. If your day is eight hours of unchanging UI, an IPS Black UltraSharp is safer.
05 Can it replace a gaming monitor? +
For single-player and console gaming, easily - 120 Hz with a 0.03 ms response is clean. For competitive shooters you would want 240 Hz or more.
