SpinetiX HMP400
Professional 4K signage player
built on DSOS
The SpinetiX HMP400 is a professional-grade digital signage media player built for screens that are not allowed to fail. It runs DSOS — SpinetiX's secured, non-replaceable operating system — on fanless, purpose-built hardware: Intel Atom x5-E3930, 4 GB RAM, industrial eMMC storage, DCI 4K output at 60 fps, and a typical draw of just 9W over PoE+. No Windows. No Android. No moving parts.
Available from local stock in Dubai through Media La Vista, the official SpinetiX Master Distributor for the Middle East since 2007 — with warranty processed locally and engineers in your timezone.
Signed Firmware Only
DSOS runs exclusively SpinetiX-signed firmware — unsigned code will not install. No third-party apps, no USB driver model, no exceptions. See the security architecture.
Built for 10+ Years
SpinetiX players run 10+ years in the field with a 0.4% failure rate. No fans to seize, no drives to fail — the maintenance budget is the thing you stop paying.
One Cable, 9W
PoE+ delivers data and power together at a typical 9W. A PC-based player in the same role draws 65–150W and needs its own outlet.
Local Stock & Warranty
Master Distributor since 2007. Dubai stock, 3-year warranty extendable to 5, processed locally — not shipped to another continent and back.
Purpose-built hardware running a purpose-built OS
The HMP400 runs the DSOS operating system, connects to ARYA cloud CMS, and supports the full content automation layer — the same platform described in our SpinetiX platform overview.
DCI 4K at 60 FPS
Native DCI 4K (4096×2160) and 4K UHD (3840×2160) output at 60 fps. Hardware-accelerated rendering engine — not a browser, not an app. Content is SVG-based and resolution-independent, so one project renders identically at 1080p and 4K.
DSOS — Purpose-Built OS
Runs DSOS, SpinetiX's secured, non-replaceable operating system. No Windows, no Android, no consumer OS underneath — and therefore no inherited CVE surface from Log4j, Heartbleed, Dirty Pipe or Meltdown/Spectre.
Fanless, Zero Moving Parts
Passive heat dissipation across the full 0–40 °C ambient range. No fans, no filters, no drives to spin down. Industrial-grade eMMC with the OS held in a higher-endurance SLC area — built for continuous 24/7/365 duty.
PoE+ or USB-C Power Delivery
Power over Ethernet (802.3at PoE+) means one cable carries data and power — ideal for ceiling mounts and hard-to-reach positions. Or run USB-C Power Delivery 2.0. Typical draw is 9W; 14W maximum.
Elementi X and ARYA Cloud
Author locally in Elementi X, or manage the whole fleet from any browser with ARYA cloud CMS. Publish to one player or a thousand — the same architecture scales without redesign.
Data-Driven by Design
Connect Power BI, Google Sheets, RSS, calendars, JSON APIs and IoT sensors. Screens update themselves with no middleware in between — the automation layer is part of the platform, not a bolt-on.

When to choose the HMP400 and when not to
Honest positioning saves everyone a return. The HMP400 is not the cheapest way to put pixels on a screen — it is the way to keep them there for a decade. Here is where that trade is worth making, and where it is not.
Choose the HMP400 when
- → The screen is mission-critical — a black screen costs money, safety or reputation
- → The install is long-life and you are costing it over 10 years, not 2
- → The position needs PoE+ — ceiling mounts, video walls, no nearby outlet
- → You need lockable HDMI and USB-C so a cable cannot be knocked loose
- → A security team has to approve what goes on the network segment
- → The site runs 24/7/365 and hot, and fans are a liability
- → Content is data-driven and must keep rendering when the network drops
Consider the EMP-III instead when
- → The zone is non-critical — a short outage costs nothing
- → You are building a rental or DSaaS fleet where unit price drives the model
- → It is a proof-of-concept or a temporary event install
- → You need units this week from permanent stock
Both run the same DSOS and the same content, so you can mix them in one fleet — HMP400 on the screens that must not fail, EMP-III on the rest. Compare the EMP-III →

The attack surface
that was never built.
Most signage players are general-purpose computers wearing a costume. They inherit every CVE that Windows or Android inherits, and every emergency patch cycle that follows. DSOS is not a hardened consumer OS — it is a different thing entirely, and the vulnerabilities simply have nowhere to land.
Zero Known CVE Impact
- → No impact from Log4j, Heartbleed, Dirty Pipe or Meltdown/Spectre
- → Signed firmware only — unsigned code will not install
- → Secured, non-replaceable OS — no app store, no side-loading
- → Quarterly updates, auto-applied and signed — no forced reboots mid-day
- → No OS UI, so pop-ups on screen are impossible
Warranty & Local Support
- → 3-year limited hardware warranty included
- → Extendable to 5 years for long-term installations
- → Warranty processed locally in Dubai — not shipped abroad
- → Direct escalation path to the manufacturer
- → Master Distributor for the Middle East since 2007
FAQ
What is the difference between the HMP400 and the HMP400W?
They are the same player. The HMP400W adds integrated Wi-Fi — IEEE 802.11a/b/g/n/ac Wave 2 with 2×2 MIMO — for sites where running Ethernet to the screen is impractical. Every other specification is identical: same Intel Atom x5-E3930 SoC, same 4 GB RAM, same DCI 4K output, same DSOS. If the position has a network drop, the HMP400 is the straightforward choice; if it does not, the HMP400W removes the cabling problem.
Should I choose the HMP400 or the iQnetiX EMP-III?
The HMP400 is SpinetiX-built hardware for installations where uptime is the requirement — mission-critical screens, long-life deployments, PoE-powered positions, and sites that need lockable connectors so a cable cannot be knocked out. The EMP-III is an approved third-party player running the same DSOS at a lower price point, aimed at non-critical zones, rental fleets and DSaaS models. Both run the same operating system and the same content, so you can mix them in one fleet: HMP400 on the screens that must not fail, EMP-III on the ones where a short outage costs nothing.
How does the HMP400 draw so little power?
It is not a general-purpose computer running signage software — it is purpose-built hardware running a purpose-built OS. Typical draw is 9W, with a 14W maximum excluding USB loads. A PC-based player in the same role draws 65–150W. Across a fleet the difference compounds: the electricity, the cooling load, and the fan and drive failures that come with it all disappear.
Can the HMP400 be powered over Ethernet?
Yes. It accepts 802.3at PoE+, so a single cable delivers both data and power. This matters most for ceiling mounts, video-wall positions and any location where adding a power outlet means calling an electrician. Alternatively it runs on USB-C Power Delivery 2.0 at 27W.
What makes the HMP400 a security decision rather than just a hardware decision?
DSOS is secured and non-replaceable, and it runs only SpinetiX-signed firmware — unsigned code will not install. There is no consumer OS underneath, no third-party app store and no USB driver model, which is why DSOS has zero known CVE impact from the vulnerabilities that force emergency patch cycles on Windows and Android fleets. On a network segment that a security team has to sign off on, that is the difference between an approval and a six-month argument.
Can I buy the HMP400 locally in the Middle East?
Yes. Media La Vista FZCO has been the official SpinetiX Master Distributor for the Middle East since 2007. That means local stock in Dubai, warranty processed locally rather than shipped abroad, a direct escalation path to the manufacturer, and engineers in your timezone.
