MuxLab 500511 - HDMI 2.1 1x4 Splitter with Downscaling and 48Gbps Bandwidth
The MuxLab 500511 represents the cutting edge in audiovisual signal distribution, specifically designed to meet the demands of the most demanding installations requiring the HDMI 2.1 standard. This high-performance splitter takes a single HDMI video source and replicates it simultaneously on four different displays without loss of quality or latency, ensuring that signal integrity remains flawless from source to display.
With an impressive 48 Gbps bandwidth (FRL), this device is ready to handle the highest resolutions on the market today and in the future, including 8K at 60 Hz and 4K at 120 Hz . This makes it the ideal centerpiece for environments where image fidelity and motion smoothness are critical, such as next-generation gaming setups, high-end home theaters, or professional digital signage. Furthermore, its HDCP 2.3 compatibility ensures playback of protected content from major streaming platforms and UHD Blu-ray players.
One of the MuxLab 500511's greatest strengths is its intelligent signal management. It incorporates advanced automatic downscaling functions, allowing you to connect an 8K or 4K source and distribute the signal to displays with lower resolutions (such as 1080p) without the main source having to reduce its quality for everyone. It also manages automatic HDR-to-SDR conversion, facilitating the integration of older monitors into modern systems.
