A 31.5-inch screen rarely sits on a desk by itself; it usually shares that desk with an external drive, a card reader or a second peripheral that a 24-inch hub monitor's desk never needed. That extra peripheral load is what actually decides whether the Dell Pro 32 Plus P3225DE's built-in hub, at R8,799, is enough, or whether a separate dock still earns its place alongside it.

Quick Answer

A hub monitor folds the dock into the screen, so the desk holds one powered box instead of two. A separate dock still wins when you keep an older panel or need ports the screen leaves out, at the cost of a second warranty to chase. This Dell is R8,799.

🎬 Why a large screen's desk asks more of its ports

The size of the monitor is a clue about the kind of work happening on that desk, and it is worth reading that clue honestly before assuming the built-in hub covers everything.

A 31.5-inch panel is disproportionately popular with people doing photo review, video editing or spreadsheet-heavy analysis, work that tends to come with an external SSD, a memory card reader, or occasionally a second monitor run independently rather than daisy chained. None of those are ports this monitor's built-in hub provides; its downstream USB sockets cover a keyboard and mouse comfortably but were never sized for a card reader and a drive running at the same time as peripherals.

🧮 Where the built-in hub genuinely falls short of a dedicated dock

Naming the specific gap, rather than a vague "docks have more ports," makes the decision concrete.

A dedicated docking station aimed at creative work typically adds an SD or microSD card reader, a second independent video output for a genuinely separate second screen rather than one daisy-chained from the first, and often more total USB-A and USB-C sockets than a monitor's chassis has room for. If your desk already needs any one of those three, the built-in hub is not a downgrade so much as simply the wrong tool, and a standalone dock from the docking station range alongside this screen is the more honest fit.

💺 Where the built-in hub is genuinely enough

For a large share of desks built around this size, none of that extra capability is actually needed, and it is worth being clear about that too.

A desk running documents, spreadsheets, browsers and video calls, even at 31.5 inches, rarely touches a card reader or a second independent display output. For that pattern of use, the built-in RJ45 port, downstream USB sockets and 90W charging cover everything a separate dock would add, at a lower total cost and with one warranty instead of two. Browse the office monitor range to compare other panels at this feature level, and check use hubs for a small standalone expansion if only the USB count falls short.

🔋 Charging behaves identically either way

Whichever route fits your peripheral needs, this specific spec is not what should decide it.

Both a hub monitor and a standalone dock rely on the same USB-C Power Delivery standard, so a 90W hub monitor and a 90W dock charge a laptop identically from the laptop's point of view. The decision genuinely comes down to peripheral needs and desk space, not to any difference in how reliably either route charges the machine.

Frequently Asked Questions

Does this monitor's built-in hub include a card reader?

No. Card readers are specifically the kind of port a creative-focused external dock adds that this monitor's built-in hub does not carry.

Can I run a genuinely separate second monitor, rather than a daisy-chained one, from this screen's hub?

Not through the monitor's own ports; that specific capability needs a dock with two independent video outputs instead.

Is it worth buying both a hub monitor and a separate dock?

Only if your peripheral needs genuinely exceed the built-in hub's ports; otherwise the dock's extra capability goes unused while still costing extra desk space.

Does a bigger monitor always mean I need a dock too?

No. Screen size is a clue about likely workload, not a rule; plenty of 31.5-inch desks run entirely on documents and calls, where the built-in hub is enough on its own.

Is it awkward to run a dock and this monitor's own hub side by side?

Not particularly. Plenty of creative desks do exactly this, treating the monitor purely as a screen and charger while the dock handles everything peripheral-related.

Can a dock and this monitor's own hub run side by side without conflicting?

Yes. Plugging a standalone dock into one of the monitor's downstream USB ports, or directly into the laptop alongside the monitor's own cable, works without either interfering with the other's video, charging or data functions, and it is a common way to add a card reader without replacing the screen or losing the monitor's own charging and video convenience anywhere along the way to getting it.

🧾 A five-minute audit before you decide either way

Rather than guessing which category your desk falls into, a short physical count settles it.

Walk over to your current desk and list every device plugged into the laptop right now that is not a monitor, a keyboard or a mouse: an external drive, a card reader, a second screen, an audio interface, anything else. 2 or fewer such devices, all of them low-power USB-A peripherals, generally sit comfortably within this monitor's built-in hub. 3 or more, or anything requiring its own independent video output rather than a daisy-chained signal, is the point where a separate dock earns its keep alongside the screen rather than being replaced by it.

💼 What creative and office desks each typically settle on

Seeing where similar desks usually land helps calibrate your own count against a real-world pattern rather than a hypothetical one.

A desk doing photo culling, video review or multi-track audio work typically settles on keeping a dock even after adding this monitor, using the screen purely for its display and charging while the dock handles card readers and drives. A desk doing spreadsheets, documents, browsers and calls for the next 3 to 5 years typically finds the built-in hub is the last USB-related purchase it ever needs to make, retiring whatever dock or dongle collection came before it.
