The Dell UltraSharp U4025QW is a 40-inch curved monitor with up to 5K display resolution support, designed to deliver both high visual performance and extended functionality through its built-in USB hub, camera, speakers, and microphone. When paired with a ConnectPRO Advanced-DDM class DisplayPort KVM switch (UDP2-12AP), users can configure the monitor in two ways depending on their use requirements:Â Setup A: Share as a Display Only or Setup B: Share as a Whole Console.
The attached diagram highlights these two different approaches, each with unique advantages and trade-offs. Here’s a detailed breakdown of both setups and why an user might prefer one over the other.
Note the computers used in the setups below are all running Windows 11 OS. These setups aren't meant for users who are using Mac and/or Linux computers in their setups.Â
Setup A: Share as a Display Only
Configuration:
-
Uses a DP 2.1 cable between the KVM switch and the Dell U4025QW monitor.
-
Provides video support up to 5120 × 2160 resolution at 120Hz, maximizing display performance.
-
The monitor’s built-in USB hub, camera, and audio are not connected through the KVM switch, so they won't work with the KVM switch
Benefits:
-
Faster Switching Time: Because only video is being switched, switching between computers through the KVM switch are quicker and more seamless.
-
Independent USB Usage: The KVM switch’s USB hubs remain free for other shared peripherals since the monitor’s hub is not part of the switching setup.
-
Maximum Display Performance: Users can fully leverage the monitor’s high-resolution 5K capabilities up to 120Hz without potential bandwidth bottlenecks.
Limitations:
-
The built-in USB hub, webcam, speakers, and microphone on the Dell monitor will not work in this setup.
-
Requires USB peripheral devices to be connected either directly to each computer system or through the KVM switch’s own USB sharing ports in order to use them.
Why Users Would Prefer Setup A:
Setup A is best for professionals who prioritize display performance and responsiveness above all else. For example, video editors, 3D designers, gamers, and engineers working with high-refresh-rate graphics will benefit from the full 5K/120Hz experience. Users who already rely on external webcams, speakers, and USB hubs will not miss the monitor’s built-in features.
Setup B: Share as a Whole Console
Configuration:
-
Uses a Thunderbolt cable between the monitor and KVM switch, with a DisplayPort + USB to USB-C converter to manage both display and data.
-
This integrates video, audio, camera, and USB hub functionality of the monitor into the KVM switching process.
Benefits:
-
Complete Docking Solution: The Dell monitor acts as a hub, consolidating multiple devices (USB peripherals, camera, and speakers) that can all be switched seamlessly between computers.
-
Single Console Control: Users interact with the monitor as a whole system—everything (display, peripherals, and audio) switches together.
-
Streamlined Workflow: Ideal for users who want fewer cables and external devices cluttering their desk.
Limitations:
-
The monitor’s built-in USB hub is limited to a combined 10Gbps data rate across all connected devices. Heavy data transfers can reduce performance.
-
Shared USB hubs on the KVM switch are fully occupied by the monitor’s USB integration, leaving no room for additional shared devices.
-
Switching can take longer than Setup A since multiple device types are being switched at the same time.
Why Users Would Prefer Setup B:
Setup B is best suited for professionals who value convenience, integration, and minimal clutter. Remote workers, office professionals, or hybrid users who rely on video conferencing (camera/mic), USB accessories, and audio will benefit most. It transforms the Dell U4025QW into a single-console workstation hub, reducing the need for external docks and simplifying cable management.
Comparison Table
| Feature | Setup A: Display Only | Setup B: Whole Console |
|---|---|---|
| Video Resolution | 5120 × 2160 up to 120Hz | 5120 × 2160 (limited by USB/TB data) |
| Monitor USB Hub | Doesn't work | Fully Functional |
| Camera & Audio | Doesn't work | Fully Functional |
| Switching Speed | Faster | Slower |
| Bandwidth Limitation | None | 10Gbps shared across all USB devices |
| USB Sharing on KVM Switch | Free for other devices | Fully occupied by monitor hub |
| Best For… | Performance-focused users, designers, gamers | Convenience-focused users, remote workers, conferencing setups |
Conclusion
Both setup options provide value depending on the user’s priorities.
-
Choose Setup A if you want maximum display performance and fast switching speed while managing peripherals separately.
-
Choose Setup B if you prefer an all-in-one docking experience where the monitor handles not just video, but also audio, camera, and USB hub functionality, even if it means some bandwidth trade-offs.
In short, Setup A favors speed and performance, while Setup B favors integration and convenience.
