MuxLab 500426 - 1x4 HDMI Distributor 4K/60Hz with Independent Downscaling
The MuxLab 500426 is a high-performance HDMI splitter designed for demanding professional and residential environments that require absolute signal integrity. This device allows you to distribute a single HDMI 2.0 source (such as a 4K Blu-ray player, a next-generation game console, a PC, or a media server) to four HDMI displays simultaneously . Its ability to handle bandwidth up to 18 Gbps ensures pristine image quality, supporting native resolutions up to 4K at 60Hz with 4:4:4 color sampling .
What truly sets this model apart from other standard distributors is its advanced independent downscaling technology for each output . In installations where state-of-the-art 4K monitors coexist with older 1080p displays, the MuxLab 500426 automatically adjusts the signal for each port. This means you can display true 4K content on your compatible displays while simultaneously delivering a 1080p signal to Full HD monitors, without degrading the quality of the original source for the entire system. Built in a robust metal housing and featuring advanced EDID management, it's the ultimate solution for avoiding resolution conflicts and HDCP handshake issues.

Benefits for the integrator and the end user
The MuxLab 500426 eliminates one of the most common headaches in video distribution: the "lowest common denominator." With conventional splitters, if you connect a 4K TV and a 1080p TV, the system typically downscales all displays to 1080p. With this device, each display receives the maximum resolution it can support , maximizing your investment in display hardware.
Its installation is plug and play, but it offers diagnostic tools via LED indicators that allow you to check the power status and input/output synchronization at a glance. The metal casing not only provides physical durability but also improves heat dissipation and protects the signal against electromagnetic interference, which is vital in commercial environments saturated with electronics.
Use cases
-
Home Cinema Systems: To send the signal from a 4K decoder to the main projector and secondary televisions in other rooms without losing quality.
-
Digital Signage: Distribution of identical advertising content to four screens in retail stores or corporate lobbies.
-
Classrooms and Training Rooms: Simultaneous display on the instructor's screen and multiple support monitors for students.
-
Boardrooms: Connect a laptop to multiple screens or projectors for clear and legible presentations from any angle of the table.
-
Electronics stores: Demonstration of 4K content on multiple televisions simultaneously for image quality comparison.
Frequently Asked Questions
Can I connect a 4K display and a 1080p display at the same time?
Yes, the MuxLab 500426 has independent scalers on each output. The 4K display will receive the 4K signal, and the 1080p display will automatically receive a scaled-up version to Full HD.
Does it support Dolby Atmos?
Yes, the device allows direct pass-through of advanced audio formats, including Dolby Atmos and DTS:X, ideal for surround sound systems.
Is it compatible with protected sources like Netflix or Blu-ray UHD?
Absolutely. The device complies with HDCP 2.2, the copy protection standard required to play commercial 4K content.
Does it require software configuration?
No, the device primarily operates automatically. However, it has physical DIP switches to adjust the EDID's behavior if needed for a specific installation.
Project description
Professional 1x4 HDMI signal distributor with support for HDMI 2.0 and 18 Gbps bandwidth.
