When using the AudioVision adapter, you must also have the ADB cable connected to the ADB port on the AudioVision 14 Display. The ~AudioVision extension polls the ADB port on the computer to see if the display is connected. If the extension does not sense the AudioVision 14 Display, an X appears over the extension at startup.
If you are using the AudioVision 14 Display connected to the HDI-45 video connector on a Power Macintosh, then there will be an ADB connection built in to the HDI-45.
However, if you are using the AudioVision adaptor (a cable with multiple cables and connectors on it), make sure the ADB part of the adaptor is connected to the computer. Otherwise, if there is no ADB cable going from the computer to display, the extension will not detect the monitor. Once you connect an ADB cable from your computer to the AudioVision 14 Display, you can connect your keyboard to one of the other ADB ports on the display.
In cases where the ADB cable is connected, and you still get the AudioVision extension loading with an 'X', you may need to reset the AudioVision 14 Monitor using the procedure described in the Tech Info Library article titled "AudioVision 14" Display: How to Reset the Monitor." Another Tech Info Library article titled "AudioVision Display: "X" Displayed Through the Video INIT" describes other conditions under which the extension loads with an 'X' through it.
