Check the connector orientation before replacement
The RV901 and RV921 share a family document, but the model table places their output interfaces on different sides. Use the RV921 rear-side layout and the actual connector gender when checking fit; do not assume the boards mount interchangeably without inspecting the cabinet.
The family document defines normal and 20-group parallel-data modes. The 50-pin signal assignment changes with the mode, so follow the pinout table that matches the screen configuration.
The stated 12-bit HDMI color support is a control-system feature requiring a ninth-generation sending card; it does not mean RV921 has an HDMI input socket. Hot backup and optional environmental monitoring need the appropriate additional hardware.
