Compaq 8030 manual Input Recall, User Input Selection

Upon initial power-up, if the monitor determines that Channel 1 is connected, but the host PC is OFF or sending sleep commands, or Channel 1 does not have a video cable attached, the monitor displays Channel 2 video, if valid.

If all video inputs are connected to video sources that are not active (i.e., the host CPU is OFF or is sending energy saving commands to the monitor), the monitor enters sleep mode.

If no valid video signals are detected (no connection), the “Check Video Cable” OSD message appears and the monitor enters sleep mode.

Input Recall

The monitor includes memory for Channel 1 and Channel 2 so that the monitor can store (and recall later) the video inputs that were used in the previous session. On the next power-up, the monitor polls the video inputs that are stored in memory. If valid video is present, the recalled inputs are displayed. If a valid signal is not present (i.e., host PC is off or video cables are not connected) on either of the two inputs stored in memory, the monitor enters the default input search mode described in the previous section.

User Input Selection

This section details the video input detection requirements for the User Select mode. Using the OSD, the user has the ability to set the desired video input for each Input Channel (User Input 1 and User Input 2). In addition, the user can select the default input channel, which has priority anytime valid video is displayed.

For each input channel, once the user input has been selected using the OSD, the monitor ceases the input recall and/or automatic detection mode for that channel. The user inputs have priority at power-up if valid (including sleep) video signals are present.
