Dell U2724DE has a video-and-data Thunderbolt upstream and a separate data-only USB-C upstream. Buyers adding a second computer should not assume that both sockets provide the same screen-input function. This US documentation-based buying guide covers U2724DE, checked on 3 October 2026. It does not transfer hub features to U2724D, test switching behavior or supply a cabling procedure.
Use the exact port descriptions
The Dell US U2724DE record labels the Thunderbolt 4 upstream as Video + Data with DisplayPort 1.4 alternate mode and power delivery up to 90W. It separately labels a USB Type-C upstream as data only, at USB 10Gbps. The connectivity section also lists HDMI and DisplayPort inputs. No exact update date is visible in the cited specification sections.
Specify what must move between computers
Our editorial comparison starts with a switching brief rather than a socket count. Write which computer should display an image, which peripherals should be available and whether laptop power is part of the desired arrangement. These are separate functions, even when a single connection can supply more than one of them.
For example, a desktop and a laptop may each have a valid image route but require different data connections. The existence of a data-only upstream is useful to understand, yet it does not independently confirm how a particular switching configuration will operate. A buyer should request the exact-model manual’s supported arrangement before describing the desk as a tested shared workstation.
| Requirement | Relevant record | Question still to answer |
|---|---|---|
| Computer image | Named video-capable input | Does the actual host supply that route? |
| Peripheral data | Upstream/downstream data roles | Which host needs access in each desk state? |
| Laptop power | Bounded power-delivery statement | Does it meet the exact laptop’s documented needs? |
| Two-computer transition | Exact supported switching arrangement | What changes automatically and what requires user selection? |
Draw two desk states
Use one sketch for laptop work and another for desktop work. Put the intended screen source and keyboard/mouse owner into each sketch. A third sketch can represent disconnecting the laptop. This exposes ambiguities that a generic one-cable slogan may conceal, especially when a connection supplies data without video.
The sketches are editorial planning aids, not demonstrations carried out with this monitor. They should prompt targeted compatibility checks. Do not infer simultaneous access, seamless switching or an arbitrary charging arrangement from the port labels alone. Those behaviors need the complete manual, host details and a relevant evaluation.
Evidence and offer limits
We have not measured USB throughput, charging rate, image quality or switching delay. Advertised interface rates are not file-transfer measurements. Needs editor verification: the exact two-host arrangement, laptop requirements, current manual and actual included cables. No seller price, current stock or warranty conclusion is provided.
The useful buying distinction is the different function of the two upstream ports. Keep U2724DE’s full suffix attached to the evidence. Our Editorial Policy separates manufacturer-stated connectivity from verified workstation behavior and firsthand reviews.
