What Is a 22-Inch All-in-One PC?
A 22-inch all-in-one (AIO) PC combines the display, processor, memory and storage into a single compact unit, eliminating the separate tower and reducing cable clutter. HP's AIO 22 family — including models such as the 22-c0023w, 22-c0000nx, 22-dd0224 and the newer 22-dg0040 — is a well-known example of this form factor, typically pairing a 21.45" to 21.5" Full HD (1920 x 1080) panel with an entry-level Intel processor. The 22-dg0040, for instance, is offered with an Intel N-series (Pentium N200) processor, 8 GB DDR5 memory and a 512 GB SSD running Windows 11 Home. These machines are designed for everyday computing: browsing, office productivity, point-of-sale terminals, reception desks and light kiosk duty.
Key Specifications to Compare
When evaluating any 22-inch AIO, the practical differences come down to processor class, memory, storage, connectivity and thermal design. Fanless models are preferred in dusty or quiet environments because they have no moving intake fan to clog or fail. Below is a general comparison of the specifications typically found in this class of machine.
| Feature | Typical 22" AIO (entry class) | Thinvent All-in-One / Mini PC options |
|---|---|---|
| Display | 21.45"–21.5" FHD (1920x1080) | 21.5" or 23.8" FHD AIO |
| Processor | Intel N-series / Pentium class | Intel Celeron, N-series, Core i3/i5 |
| Memory | 8 GB typical | 4 GB to 64 GB DDR4/DDR5 |
| Storage | 256–512 GB SSD | 128 GB to 1 TB SSD |
| Cooling | Often fan-cooled | Fanless designs available |
| OS | Windows 11 Home | Windows 11 Pro, Ubuntu, Thinux™, FreeDOS |
| Mounting | Desk stand | VESA-mountable in many models |
Where 22-Inch AIOs Fit Best
All-in-one PCs in the 22-inch range are popular in retail billing counters, clinic reception desks, hotel front offices, school computer labs and information kiosks. Their single-cable footprint makes them easy to deploy at scale, and the integrated screen keeps counters tidy. For industrial or shop-floor use, however, buyers should check whether the unit is fanless, whether it supports a wide input voltage, and whether it offers legacy I/O such as serial (DB9) ports for connecting scales, printers or PLCs. Standard consumer AIOs rarely include these, which is why many system integrators look at industrial-grade alternatives.
Choosing Between a Consumer AIO and an Industrial Alternative
A consumer 22-inch AIO is a good fit for climate-controlled offices and homes. In environments with dust, heat, vibration or 24x7 operation, an industrial-grade all-in-one or a fanless mini PC paired with a separate monitor often delivers longer service life and easier maintenance. Key questions to ask: Is the storage field-replaceable? Does the unit accept 12V DC input? Are there enough USB and serial ports for peripherals? Does the operating system option include Windows 11 Pro, Linux or a no-OS configuration for custom deployments?

The closest match is the Thinvent Industrial PC IPC3, which shares the same 12th Gen Intel Core i3-1215U processor as the HP AIO PC 22-dd2456in, ensuring comparable everyday performance for office and productivity tasks. The key trade-off is form factor: the HP is an all-in-one with a built-in 21.5" display, while the Thinvent IPC3 is a standalone industrial PC that requires a separate monitor, but it offers double the RAM (16GB) and a full 1TB of storage in a more rugged, serviceable chassis.
