Published 30 September 2026 · Feroz Sheikh, publisher · How we review evidence
Dell UltraSharp U2722DE has USB-C video / DisplayPort Alt Mode, DisplayPort, HDMI inputs in this profile. Check the actual video input before choosing a laptop cable or docking station.
| Connection detail | Documented scope |
|---|---|
| Video inputs | USB-C video / DisplayPort Alt Mode DisplayPort HDMI |
| Display modes in this profile | 2560 × 1440 at 60 Hz |
| Cable evidence | No exact supplied-cable path approved |
Use the USB-C port identified for DisplayPort and 90W power, not its separate data-only upstream or downstream ports. Daisy-chain compatibility remains unreviewed.
Choose the input before the cable
This profile includes a USB-C video input. A USB-C downstream or data-only socket on the same monitor is a different connection. Match the upstream port shown in the manufacturer manual and use a cable rated for video.
This is a 2560 × 1440 profile. Do not treat QHD as 4K or infer a 120 Hz mode from a similarly named model.
Check the complete setup
The monitor specification establishes its end of the link. Your laptop still needs a video-capable output and enough display streams; an adapter must work in the required direction. A power-delivery wattage is a maximum capability, not proof that every laptop will charge at that rate.
Manufacturer evidence
These are documentation findings, not NYBreaking hardware tests. A successful source fetch checks availability; it does not independently prove every connection.
