ATEN 4X4 True 4K HDMI Matrix Switch - VM0404HB

ATEN VM0404HB 4x4 True 4K HDMI Matrix Switch

The ATEN VM0404HB is a rack-mount 4-input, 4-output HDMI matrix switch built to route True 4K video signals — up to 4K@60Hz (4:4:4) — across four independent display zones simultaneously. If you're integrating digital signage networks, boardroom AV systems, or control room displays that need any-source-to-any-display flexibility without signal compromise, the VM0404HB is the switching layer to evaluate first in the ATEN AV distribution line.

Key Features

• True 4K@60Hz (4:4:4) at up to 5 meters: Full-chroma 4K delivery at 60 frames per second means no color subsampling artifacts on high-end displays. The 5m maximum cable distance at this signal grade is the planning constraint — budget premium HDMI 2.0 cable and keep runs tight to stay within spec.
• HDCP 2.2 compliance: Required for distributing 4K UHD content from protected sources — streaming players, Blu-ray, cable boxes. Without HDCP 2.2 end-to-end, protected 4K content won't pass; the VM0404HB satisfies both source and display handshake requirements.
• HDMI feature support (3D, Deep Color, CEC): Consumer Electronics Control (CEC) passes through the matrix, letting a single remote command trigger display power states across connected screens — a practical labor saver in multi-display venues where manual power cycling is operationally expensive.
• Four EDID management modes: Default, Port 1, Remix, and Customized (with EDID Wizard support) — EDID mismatches are the single most common cause of blank screens and resolution fallback in matrix deployments. Having four modes including a fully customizable option means you can lock source devices into outputting the exact resolution your displays require, regardless of what EDID they'd negotiate on their own.
• 100Ω impedance matching: Matched impedance on HDMI signal paths reduces reflections and signal degradation — relevant when sources and displays are from different manufacturers with varying output driver characteristics.
• Rack-mount form factor: Designed for standard equipment racks, keeping the matrix in the same enclosure as other AV infrastructure. Paired with an equipment rack or rack shelf, this integrates cleanly into a 19-inch rack bay.
• Universal AC input (100–240 VAC, 50–60 Hz): Operates on any mains voltage worldwide — relevant for international deployments or mixed-voltage facilities without needing a separate power adapter. Rated at 1.0A max draw, well within standard rack PDU circuit capacity.
• Wide storage temperature range (-20°C to 60°C): Safe for warehouse storage, shipping, and staging in unconditioned environments before permanent installation.
• IP-based management via RJ-45: The single RJ-45 Ethernet port enables remote matrix control over a network — useful in AV-over-IP or building automation environments where a control system (AMX, Crestron, or similar) needs to switch sources programmatically without physical access to the unit.
• Active firmware — latest v3.6.355 (released 2025-05-22): A current firmware release indicates the product is actively maintained. Keeping firmware current is standard practice for any networked AV device to stay ahead of HDCP handshake edge cases and EDID compatibility updates.

Integration and Compatibility

The VM0404HB sits in HDMI matrix switch deployments where four discrete display zones need independent source assignment. HDCP 2.2 compliance makes it compatible with the full stack of modern protected-content sources. The EDID Remix and Customized modes, including EDID Wizard support, give integrators precise control over source-to-display resolution negotiation — particularly valuable when mixing display generations or brands on the output side.

Ethernet control via the RJ-45 port allows integration with third-party control systems for centralized AV management. CEC passthrough reduces control complexity for consumer-grade display installations. For larger matrix requirements — more inputs, more outputs, or longer cable runs requiring extenders — consider higher-channel variants in the ATEN VM series.

Frequently Asked Questions

Q: What is the maximum cable length supported at 4K@60Hz (4:4:4)?

A: The VM0404HB supports a maximum cable distance of 5 meters when operating at 4K@60Hz (4:4:4). Longer runs will require signal extenders or a reduction in resolution/frame rate.

Q: Does the VM0404HB support HDCP 2.2 for 4K protected content?

A: Yes. The VM0404HB is HDCP 2.2 compatible, which is required for distributing 4K UHD content from protected sources such as streaming devices, 4K Blu-ray players, and cable/satellite receivers.

Q: What EDID modes are available on the VM0404HB?

A: Four modes are supported: Default, Port 1, Remix, and Customized. The Customized mode includes EDID Wizard support, allowing integrators to define a precise EDID profile to prevent resolution fallback or blank-screen issues across mixed display environments.

Q: Can the VM0404HB be controlled remotely over a network?

A: Yes. The unit includes a single RJ-45 Ethernet port for IP-based remote control, enabling integration with third-party control systems without requiring physical access to the matrix switch.

Q: Does the VM0404HB support Consumer Electronics Control (CEC)?

A: Yes. CEC passthrough is supported, allowing compatible displays connected to the matrix to respond to remote power and control commands — useful in multi-display venues where individual display power management is needed.

Q: What input voltage does the VM0404HB require?

A: The VM0404HB accepts universal AC input: 100–240 VAC at 50–60 Hz, drawing a maximum of 1.0A. No step-down transformer or country-specific adapter is needed for international deployments.

The spec that shapes every VM0404HB deployment decision is the 5-meter maximum cable distance at 4K@60Hz (4:4:4). Most integrators don't read that footnote until they're on-site with 10-meter HDMI runs and a blank screen. Plan your rack-to-display distances before you spec this unit — or budget HDMI extenders into the BOM from the start.

Technical Highlights:

• HDCP 2.2 end-to-end: The full source-to-display HDCP 2.2 chain is a hard requirement for 4K UHD protected content — one non-compliant display breaks the handshake for that output. Verify every display in your matrix before specifying.
• Four-mode EDID management: The Customized EDID mode with EDID Wizard support is what separates this from passive splitters. Locking sources to a defined EDID profile eliminates the resolution negotiation failures that cause callbacks on multi-brand display installs.
• Universal AC input at 1.0A max: 100–240 VAC draw means no power conversion needed in international or mixed-voltage facilities, and 1.0A maximum keeps rack PDU load planning simple — roughly 100–240W maximum depending on mains voltage, well within a single 15A circuit breaker even with a full rack.

Deployment Considerations:

• IP control via the single RJ-45 port is network-dependent — segment this on a dedicated AV VLAN if the control system is Crestron or AMX, and document the IP address assignment in your as-built drawings so future service calls don't require physical access to identify the unit.
• The 5m cable distance limit at 4K@60Hz (4:4:4) is a hard ceiling, not a guideline — signal degradation at longer runs won't produce a clean degraded image, it will produce handshake failures or no signal. HDMI 2.0 active cables or fiber extenders are required for anything beyond 5 meters.

The VM0404HB is the right fit for boardroom AV installations and digital signage hubs where four sources and four displays are fixed, cable runs stay under 5 meters, and the integrator needs reliable HDCP 2.2 compliance and programmatic IP control — not for large-venue or long-run installs where an HDBaseT or AV-over-IP matrix would be the appropriate architecture.
