MuxLab 500840 HDMI/3G-SDI Triple Display, 4K/30

The 500840-V2 puts three independent 5-inch IPS displays in a 2RU rack panel, each accepting HDMI at up to 4K/30, 3G-SDI, or CVBS, with per-display tally lights so a technical director can see which camera is live at a glance.

Built-in waveform, histogram, and vectorscope tools turn each panel into a lightweight signal-quality check, and center marker, safe frame, and focus-assist overlays support both camera operators and a master control bay.
