Vertiv HMX8000R-400 IP KVM Receiver — 4K Dual-Display, 10GbE Fiber
Overview
The Vertiv HMX8000R-400 is the receiver unit in the Avocent HMX8100R IP KVM extender family, designed for broadcast studios, trading floors, government operations centers, and any high-density control room where operators need full 4K resolution at the desk without housing compute hardware in the room itself. The HMX8000R-400 (often searched as HMX8000R 400) sits at the operator workstation, connecting back to a remote transmitter over a 10 Gigabit Ethernet fiber link — keeping servers in a cooled, secure machine room while operators work with native-resolution video and responsive keyboard/mouse control at distances fiber supports.
This is not a compressed-video KVM workaround. The 10GbE backbone delivers enough bandwidth to push 4096 x 2160 at 60 Hz to two simultaneous displays — the kind of throughput that matters when your operators are running video editing software, financial analytics dashboards, or medical imaging applications where frame-accurate, color-accurate rendering is non-negotiable.
Key Features
- 4K @ 60 Hz dual-head output (4096 x 2160): Two independent DisplayPort outputs drive two full 4K monitors simultaneously from a single receiver unit — useful on trading desks or control room consoles where operators routinely span applications across multiple screens. You get the full pixel budget on both heads, not a split or downscaled feed.
- 10 Gigabit Ethernet over fiber: The single RJ-45 network port connects to your 10GbE infrastructure, with fiber cable support eliminating ground-loop and EMI concerns common in broadcast or industrial environments. At 10GbE, the link can sustain lossless 4K transport without the compression artifacts that appear on lower-bandwidth KVM extenders.
- 5x USB 2.0 Type-A ports: Four ports are available for peripherals at the operator station — keyboard, mouse, USB headset, CAC reader, security token — without a hub. Standard USB 2.0 is sufficient for HID and authentication devices, and the port count means a typical operator desk is fully equipped without an external hub adding another point of failure.
- Dual DisplayPort local video outputs: DisplayPort is the correct connector choice for 4K @ 60 Hz without adapter chains. If your monitors are DisplayPort-native (as most professional-grade panels are), the receiver connects directly — no DP-to-HDMI active adapters, no refresh-rate cap from passive conversion.
- Rack-mountable metal chassis: The all-metal black enclosure supports rack installation, which matters in structured control room builds where loose desktop units create cable-management and replacement-access problems. Rack-mounted receivers also simplify inventory and hot-swap procedures during maintenance windows.
- PC audio input: The receiver passes audio from the remote host, so operators can monitor system alerts, video playback audio, or VoIP calls through desk speakers or headsets connected at the receiver — no separate audio-over-IP path to configure.
- Plug-and-play deployment: The HMX8000R-400 is designed for straightforward commissioning without specialized driver installation at the receiver end. In large-scale rollouts — 50+ seats across a broadcast facility, for example — that reduces per-seat deployment time materially compared to solutions requiring per-client software configuration.
- USB keyboard/mouse port (local): A dedicated USB port at the receiver handles the local keyboard and mouse, keeping the HID path separate from the peripheral USB bank so a USB device reconnect on one port doesn't interrupt the control interface on another.
Integration and Compatibility
The HMX8000R-400 is the receiver half of the Avocent HMX extender system and pairs with a compatible HMX transmitter unit installed at the host computer. The 10GbE fiber network link means the receiver can sit anywhere on your fiber plant — same building, different floor, or across a campus backbone — as long as the network path supports 10GbE end-to-end. The wired-only design with no wireless fallback is a deliberate tradeoff: you get deterministic latency and no RF interference, at the cost of needing structured fiber or 10GbE copper runs to each seat.
For environments already running KVM switches and extenders from the Avocent HMX line, the HMX8000R-400 integrates into existing HMX infrastructure without a forklift upgrade to the transmitter side. Buyers evaluating broader Vertiv KVM and management solutions will find this receiver fits within a larger Avocent ecosystem that includes matrix switches, management software, and multi-user access control.
Integrators planning a full control room deployment should also evaluate KVM extender categories for transmitter pairing options and consider rack accessories if building out structured 1U or 2U receiver banks in a furniture chase or equipment rack.
Frequently Asked Questions
Q: What video outputs does the HMX8000R-400 have, and what resolution do they support?
A: The HMX8000R-400 has two DisplayPort outputs. Both support 4K resolution at 4096 x 2160 @ 60 Hz, allowing two 4K monitors to be driven simultaneously from one receiver unit.
Q: What network connection does the HMX8000R-400 use?
A: It uses a single RJ-45 port configured for 10 Gigabit Ethernet, with fiber cable support. Your network infrastructure and cabling runs must support 10GbE end-to-end from the transmitter to the receiver.
Q: How many USB ports are on the HMX8000R-400, and what type are they?
A: The receiver provides 5x USB 2.0 Type-A ports for peripheral connections at the operator station, plus a dedicated USB port for local keyboard and mouse.
Q: Can the HMX8000R-400 be rack-mounted?
A: Yes. The metal chassis supports rack mounting, making it suitable for structured control room and broadcast facility builds where receivers are installed in equipment racks rather than placed on desks.
Q: Does the HMX8000R-400 support audio?
A: Yes. The receiver includes a PC audio input, allowing audio from the remote host computer to be passed through to speakers or headsets connected at the operator workstation.
Q: Is the HMX8000R-400 a standalone device, or does it require a paired transmitter?
A: The HMX8000R-400 is the receiver unit only. It requires a compatible Avocent HMX transmitter installed at the host computer to complete the KVM extender link. It does not function as a standalone KVM switch.
The HMX8000R-400 is one of those units that makes sense the moment you've tried to run a 4K dual-head workstation over an older KVM extender and watched the frame rate fall apart. With 10GbE fiber as the transport and two DisplayPort outputs rated to 4096 x 2160 @ 60 Hz each, this receiver is purpose-built for operator environments where the video feed has to be as good as local — broadcast master control, financial trading desks, and government operations centers where compromised video isn't acceptable.
Technical Highlights:
- Dual 4K @ 60 Hz DisplayPort outputs: Two independent 4096 x 2160 feeds at 60 Hz mean both monitors run at full resolution with no frame-rate penalty — critical for video production or analytics dashboards where any dropped frame or compression artifact causes rework.
- 5x USB 2.0 Type-A peripheral ports: Enough to connect keyboard, mouse, CAC card reader, USB headset, and a security token simultaneously at the operator desk without a hub. Fewer failure points in a shift-critical environment matters.
- 10GbE fiber transport: The single RJ-45 / fiber link eliminates ground-loop interference common in broadcast plant environments and provides the bandwidth headroom to sustain lossless 4K without the compression artifacts that appear on 1GbE KVM solutions.
Deployment Considerations:
- The HMX8000R-400 is a receiver unit only — budget and plan for a compatible HMX transmitter at each host. In large deployments, transmitter and receiver counts must match 1:1 unless you're adding an HMX matrix switch for shared-access configurations.
- Your switch infrastructure must support 10GbE end-to-end. If your existing access layer is 1GbE, you'll need to upgrade the uplinks or deploy dedicated 10GbE switches for the KVM VLAN — the bandwidth requirement is non-negotiable for lossless 4K transport.
For a broadcast production facility or a government operations center building out 20+ operator stations with dual 4K monitors and CAC authentication, the HMX8000R-400 receiver paired with HMX transmitters and a 10GbE fiber backbone is the right architecture — rackmount the receivers in a chase, run fiber to each console, and keep all compute in a climate-controlled, secured equipment room.
