Atlona AT-RON-4444K HDR HDMI Distribution Amplifier
The Rondo 444 splits one HDMI source across four displays at full 4K rate: 4K/UHD at 60 Hz with 4:4:4 chroma, 18 Gbps of HDMI 2.0a bandwidth, HDCP 2.2, and HDR metadata carried through untouched so HDR10, Dolby Vision, and HLG still engage on every panel. Four outputs is the count that covers a video wall quadrant, a bar with four screens, or a classroom with a projector and repeat monitors.
Because four sinks means four sets of EDID, the 444 lets you run an internal EDID or learn one from the display that matters, rather than letting the weakest monitor drag the whole chain down to 1080p. Front-panel LEDs show power and per-signal status, and Rondo units cascade, so a 1x4 can feed additional distribution amplifiers when the display count grows. The included external 5 V supply lands on a 2-pin Phoenix connector, and the unit ships with both a long and a short rack ear so it can be mounted alone or paired in a single rack space.
