HP ProOne 240 G10 All-in-One, Intel Core i5 1334U, 8GB DDR4 RAM, 512GB SSD, FreeDOS, 23.8″ FHD – Model No: 9M9H3AT

HP ProOne 240 G10 All-in-One (9M9H3AT) — 23.8-Inch Business Desktop with Intel Core i5 and 5MP Camera

The HP ProOne 240 G10 delivers a business-grade all-in-one desktop around a 13th-generation Intel Core i5 processor, a 23.8-inch Full HD IPS display, and a 5-megapixel tiltable camera — all in a slim, space-saving chassis with rear-facing ports. Specifically, it targets small and medium businesses, front-desk deployments, and hybrid office workers who need reliable performance, clean video conferencing, and a professional desk presence in a single compact unit. Furthermore, the 9M9H3AT ships with FreeDOS, giving IT departments full control over the operating system installation rather than inheriting a consumer OS build.

Use Cases

Small and Medium Business Offices

The HP ProOne 240 G10 positions itself as a workhorse for SMB office environments where desk space, professional appearance, and reliable performance all matter. In particular, the rear-facing port layout removes visible cable clutter from the front of the machine, presenting a clean desk to visitors and colleagues alike. Furthermore, the 10-core i5-1334U handles demanding business workloads — ERP software, large spreadsheets, multi-tab research, and video conferencing — without the slowdowns that entry-level processors produce at peak load. In addition, the EPEAT Gold registration and Low Halogen certification satisfy corporate and public sector sustainability procurement requirements. As a result, the 9M9H3AT represents a credible choice for multi-seat SMB rollouts where environmental compliance matters as much as performance.

Front-Desk and Reception Deployments

The ProOne 240 G10’s slim all-in-one design suits reception desks, information kiosks, and point-of-sale positions where space is constrained and appearance matters. Specifically, the adjustable-height stand and tilt display let reception staff set the screen at a comfortable angle for long shifts, while the rear-facing ports keep the desk surface clear for customer interaction. Consequently, the machine doubles as a presentable public-facing terminal without requiring a separate monitor stand or cable management solution. Moreover, HP notes the ProOne 240 G10 as suitable for digital signage and kiosk deployments, making it a flexible platform across a range of retail and hospitality front-of-house roles.

Hybrid and Video-Conferencing-Heavy Work

The 5MP tiltable camera separates the ProOne 240 G10 sharply from consumer all-in-ones in video-heavy roles. In addition, HP Auto Frame automatically reframes the shot when you move, keeping you centred in the frame without requiring manual camera adjustment. Similarly, the Be Right Back feature replaces your live feed with a still image when you step away from the desk, so colleagues see a professional placeholder rather than an empty chair. Furthermore, the dual digital array microphones capture clear audio from a natural speaking position, reducing the need for an external USB microphone in most meeting environments. As a result, the ProOne 240 G10 handles a full day of video meetings as a self-contained communication station.

Considerations

FreeDOS — Operating System Installation Required

The 9M9H3AT ships with FreeDOS rather than Windows. Therefore, running Windows applications requires purchasing a Windows 11 licence separately and performing the installation. However, for IT-managed business deployments, this configuration allows administrators to image the machine with a corporate OS build from a controlled deployment environment — avoiding pre-installed consumer software and bloatware. In short, this SKU suits businesses with existing OS licensing, not end users who want to buy and use the machine immediately out of the box.

Display Colour Gamut — 72% NTSC

The ProOne 240 G10 datasheet specifies 72% NTSC for the display colour gamut, in contrast to the 99% sRGB panel found in the consumer HP All-in-One 24-cr0315nh. Consequently, colour-critical tasks such as photo editing, graphic design review, and colour-accurate presentation work will look less vibrant on this display than on a wider-gamut alternative. However, for standard business applications — documents, spreadsheets, email, video calls, and web browsing — 72% NTSC delivers a perfectly acceptable everyday image. Therefore, users with a genuine need for accurate colour should evaluate an external display with 99% sRGB coverage alongside this machine.

Integrated Graphics Only

The i5-1334U relies on Intel UHD Graphics for all rendering. As a result, the ProOne 240 G10 handles office software, HD video playback, and video conferencing without issue, but it does not suit GPU-intensive workloads such as video editing at 4K resolution, 3D rendering, or modern gaming. Therefore, users who need discrete graphics performance should consider a tower workstation with a dedicated GPU instead.

Memory Ships as Single Channel

The 9M9H3AT ships with a single 8 GB DDR4-3200 SODIMM, leaving one slot free. Consequently, memory runs in single-channel mode at the base configuration, which limits bandwidth compared to a dual-channel 2 × 8 GB configuration. For most office tasks, the difference goes unnoticed. However, for workloads that benefit from memory bandwidth — large data sets, concurrent virtual machines, or intensive browser sessions — upgrading to dual-channel 16 GB at the point of purchase makes a meaningful difference to responsiveness.

Frequently Asked Questions

Can I install Windows on the HP ProOne 240 G10?

Yes. The ProOne 240 G10 hardware fully supports Windows 11. However, the 9M9H3AT does not include a Windows licence — it ships with FreeDOS. Therefore, you need to source a Windows 11 Home or Pro licence separately and carry out the installation. Alternatively, the machine supports mainstream Linux distributions for organisations running non-Windows environments.

How much can I expand the RAM in the HP ProOne 240 G10?

The machine supports up to 32 GB DDR4-3200 across two SODIMM slots. Consequently, the current 8 GB single-SODIMM configuration leaves room for a significant upgrade. Use DDR4-3200 SO-DIMM modules; HP recommends HP-branded memory to ensure compatibility.

Can I add more internal storage later?

Yes. The ProOne 240 G10 includes a second M.2 slot and a 2.5-inch SATA drive bay in addition to the primary M.2 slot occupied by the 512 GB SSD. Therefore, you can add a second NVMe SSD via M.2 or a 2.5-inch SATA SSD or HDD without removing or replacing any existing storage. As a result, total internal storage can grow substantially beyond the base configuration.

Does the HP ProOne 240 G10 support a second external monitor?

Yes. The rear panel includes an HDMI 1.4 output. Consequently, you can connect a second external display and run the built-in 23.8-inch screen alongside it simultaneously — useful for multi-window business workflows. Moreover, the USB Type-C port may support video output depending on the host configuration; confirm with HP support before relying on it for dual-display setups.

What makes the HP ProOne 240 G10 camera better than a standard webcam?

The 5MP tiltable pull-up camera produces a significantly sharper image than the 720p cameras common on consumer all-in-ones and budget standalone webcams. In addition, HP Auto Frame and Be Right Back require this camera and the myHP app on Windows — they do not function under FreeDOS. Therefore, plan your OS installation before relying on these conferencing features in production.

Is the HP ProOne 240 G10 suitable for point-of-sale or kiosk use?

Yes. HP specifically positions the ProOne 240 G10 for front-desk, point-of-sale, kiosk, and digital signage applications. Furthermore, the rear-facing port layout, adjustable-height stand, and slim form factor all suit fixed public-facing installations. However, confirm power and mounting requirements with your installer, as kiosk and POS deployments often need additional brackets or enclosure hardware not included in the standard box.
