The MX44HAS2 4K60 4x4 HDMI matrix routes four sources to four displays at up to 4K60 4:4:4, and if your project team is evaluating audio visual equipment suppliers alongside other audio visual suppliers, this 18Gbps unit pairs Dolby Vision and HDR10 support with coaxial audio breakout, EDID management and push-button, IR, RS-232, IP or Web GUI control for boardrooms, training centers and control rooms.
Where you buy a matrix from changes more than the price. The same part number can arrive with a different firmware revision, a different EDID table, and a different support path depending on which of these five you are dealing with.
Best for: OEM/ODM work, firmware and EDID questions that need an engineering answer, and volume projects.
Watch: minimum order quantities and lead times that follow a production schedule rather than a stock level. Spec sheets are usually the authoritative ones.
Best for: stocked units, fast delivery, and mixed-brand orders.
Watch: firmware questions get relayed rather than answered. Ask which revision is in the box before you commit.
Best for: bundling, configuration, and local support.
Watch: the spec sheet may be a rewritten copy. Verify any number against the manufacturer's own document.
Best for: design, commissioning, and someone owning the outcome on site.
Watch: you are buying a solution, so the bill of materials may not name the exact model you specified.
Best for: one-off replacements.
Watch: unverifiable provenance, no firmware support, and returns that depend on a third party. Not a route for a project with a warranty obligation.
A useful cross-check on any of them: a real manufacturer publishes a catalogue of what it builds. The 4K HDMI switch catalogue overview is what that looks like.
This is the same datasheet content a supplier will send you, annotated so each line answers a question you would otherwise discover on site.
| Published value | Why it matters in the room |
|---|---|
| 4x4 matrix, independent switching | Four sources to four displays, any input to any output. Independent means changing one room's screen does not disturb the others. |
| 18 Gbps bandwidth | The headroom that makes 4K60 4:4:4 possible. A 10.2 Gbps switch will not carry the same signal. |
| Up to 4K @60Hz YUV 4:4:4 8-bit | Full colour resolution without chroma subsampling — the difference between text on a spreadsheet staying sharp and turning soft. |
| HDR10 and Dolby Vision; HDR at 4K60 4:2:0 10-bit | HDR is carried at the bandwidth the format allows, rather than being claimed and dropped. |
| HDMI 2.0 / 2.0a, HDCP 2.2 | HDCP 2.2 is what lets protected 4K sources handshake at all. Without it the source simply refuses to output. |
| EDID management, including EDID learning | The single most common cause of “no signal” on a matrix. Learning from the connected display, or forcing a pre-programmed table, is what prevents handshake conflicts. |
| Scaler output | Lets a lower-resolution display stay in the system without forcing every source down to its ceiling. |
| Coaxial S/PDIF audio breakout per HDMI output | Audio can be extracted at each output for a separate amplifier or DSP instead of being locked to the display's speakers. |
| Control via push buttons, IR remote, RS-232, IP, Web GUI, USB | Choose the path the room already uses: a button panel for a lectern, RS-232 or IP for a control system, the Web GUI for commissioning. |
| Signal retiming, no loss of quality | Each output is re-clocked, so long cable runs do not accumulate jitter. |
| Plug and play, no driver required | Installs without a software stack on the host — a week-one commissioning cost you do not pay. |
| Metal enclosure, ESD protection, surface mountable | Shielding and heat dissipation in a rack, plus ESD protection against the failure mode that kills matrix units in service. |
| FCC, CE and RoHS compliantCertification documentation for the markets the project ships into. |
The supplier's own design notes are worth reading alongside the datasheet — technical insights into 4x4 HDMI matrix design covers why these choices are made.
Every AV project is the same four stages. A supplier is only as useful as the number of stages it can actually answer for, so map your project onto this before you shortlist.
Laptops, media players, cameras, and the video conferencing codec. The source sets the ceiling: no switcher can add resolution a source never produced.
Where the MX44HAS2 sits. It routes four sources to four displays, manages EDID so sources and screens agree, scales where a display lags behind, extracts audio per output, and re-times the signal.
HDBaseT, fibre, or active copper runs beyond the rack. Ask what extension the supplier supports, and whether it is tested with this matrix rather than assumed to work.
The screens, plus whatever issues the commands — a control processor over RS-232 or IP, a Web GUI, an IR handset, or the front-panel buttons.
A supplier that covers only stage two is a component vendor, not a project partner. One that can talk through all four — and has tested the seams between them — is the one worth the second meeting. Comparing HDMI matrix solutions for enterprise meeting rooms works through the same stages.
Ask these of every bidder. They are deliberately answerable with documents rather than assurances, and none of them depends on a particular supplier.
| Ask | What a good answer looks like |
|---|---|
| Product roadmap and firmware cadence | A dated revision history, and a route to receive updates after purchase. |
| EDID interoperability testing | Evidence that the switching units have been tested against common displays and sources, not just against the manufacturer's own bench. |
| Control-API documentation | A published RS-232 and IP command set you can hand to the control programmer before delivery. |
| RMA and spares policy | A named process, a response window, and stocked spares for the unit you are buying. |
| Certifications | The specific marks held for the model you are ordering — for this unit, FCC, CE, and RoHS. |
| MOQ | A clear figure that holds whether you ask sales or engineering. |
| Lead time | Production and shipping quoted separately, with the departure point named. |
| OEM/ODM capability | A direct answer on branding the unit and the packaging, with the artwork process described. |
| Warranty | A written term, what is excluded, and how a claim is raised. |
| Sample policy | Whether a unit can be bought at sample pricing for bench testing before a project order. |
If a bidder cannot produce the document behind an answer, treat the answer as unverified. That is the whole point of asking before the order rather than after.
Multiple sources shared between a room display, a confidence monitor, and a capture device, switched independently without re-cabling.
An instructor's source mirrored to several screens while a second source runs on a different output.
Signal retiming and EDID management matter most where a display being powered down must not take the rest of the chain with it.
Simultaneous media on multiple screens, with audio broken out per output to the house system.
Monitoring stations that need full 4:4:4 colour rather than a subsampled feed.
A matrix quote can only be accurate against a described signal chain. Send these eight points and the reply becomes a bill of materials rather than a catalogue page.
Send those through the contact page, or review the MX44HAS2 product page for the full published specification first.
