Crestron HD-MD4X1-4K-E4x1 4K HDMI Switcher Auto-Switching QuickSwitch HD

Crestron HD-MD4X1-4K-E 4x1 4K HDMI Switcher

A 4-input, 1-output 4K HDMI switcher with QuickSwitch HD fast key management, auto-switching and multiple control options including Crestron control system integration. Every unit is certified refurbished, fully tested in Melbourne and backed by a 12-month warranty from Reboot IT.

Key Benefits

• Four HDMI sources, one display. Connect up to four HDMI sources — laptops, media players, conferencing codecs and permanently wired PCs — and switch cleanly between them into a single HDMI output.
• QuickSwitch HD fast key management. Crestron's QuickSwitch HD technology manages HDCP key exchange in the background ahead of time, so switching between sources happens without the blackout delay and re-handshake pause common on cheaper switchers.
• 4K60 video support. Passes 4K60 4:2:0 video, plus 4096x2160 and 3840x2160 in 4:4:4 chroma at lower frame rates.
• Multiple ways to switch. Auto-switching, front-panel buttons, a built-in web browser interface, CEC and integration with a Crestron control system all let you choose how sources are selected.
• Built-in Ethernet control. A 10/100 Ethernet port allows network-based control and monitoring alongside the front-panel and web interfaces, useful for IT teams managing several rooms remotely.
• Certified refurbished and warranty backed. Every unit is tested by our Melbourne technicians and comes with a 12-month warranty from Reboot IT, so it's ready to install as soon as it arrives.

Performance in Use

In a boardroom, the HD-MD4X1-4K-E typically sits between a table of HDMI inputs — a laptop connection, a videoconferencing codec, a wireless presentation box and a permanently connected PC — and the room's display or projector. Auto-switching means the display simply follows whichever source is active, while QuickSwitch HD's fast HDCP key management avoids the brief black screen that many switchers show when a new source is selected, which matters when a presenter is mid-sentence.

In a classroom or training room, the same four inputs might cover a teacher's laptop, a document camera, a streaming device and a guest presenter's laptop, all switching into one projector or display. The front-panel buttons and CEC support give teaching staff a simple, familiar way to change sources without needing to touch a control system, while IT staff can still manage the unit over the network via its web interface or Ethernet port.

For AV integrators building a Crestron-controlled system, the HD-MD4X1-4K-E connects into the wider control platform over Ethernet, letting a Crestron processor drive source switching alongside lighting, audio and display control from one interface. In a live event or venue setting, QuickSwitch HD's fast key management is particularly valuable, since switching between a video source and a presentation laptop needs to happen instantly rather than pausing on a black screen. As a discontinued Crestron model, it is well suited to expanding or replacing a unit in an existing 4K switching installation rather than a brand-new platform deployment.

Day to day, the combination of auto-switching and QuickSwitch HD is what sets the HD-MD4X1-4K-E apart from a basic manual switcher. Most users never need to touch the front panel at all — the unit senses which input has an active signal and switches to it automatically, while QuickSwitch HD keeps the HDCP handshake with the display already primed in the background so there is no pause or black screen when the active source changes. For rooms where a control system isn't installed, the front-panel buttons and CEC give a simple manual override, and the built-in web interface means an IT administrator can check or change the active source remotely over the network without walking into the room. The 10/100 Ethernet port also makes it straightforward to bring the switcher into a Crestron control system later, even if it starts out running purely on auto-switching. That flexibility means the same unit can be dropped into a simple single-room install today and folded into a larger, centrally managed AV estate down the track without needing to be replaced.
