DVI signal distribution and sending-card configuration
The two DVI splitters duplicate source signals; the installed sending cards determine the LED data outputs and final screen load. Confirm the sending-card models, receiver compatibility and required source timing before ordering.
Environmental specification note: Both the original listing and supplied PDF label a 0–40 °C range as working humidity. Celsius is not a humidity unit, so that entry cannot be used as a humidity specification. Confirm the applicable environmental limits before installation.
