3.2.6 Managing EDID video display information

Whenever a ServSwitch Wizard VGA (USB) unit is powered on (or when the option F 2 is selected from the configuration menu), it will interrogate the connected monitor(s) to determine whether EDID (Extended Display Identification Data) information is avail- able. If EDID information is available, it will be copied and used; otherwise a default set of data, stored within the ServSwitch Wizard VGA (USB), will be substituted. You can also optionally choose to prevent the unit from seeking new EDID information and instead rely only on stored data.

EDID Emulation

The ServSwitch Wizard VGA (USB) units use an EDID Emulation feature to ensure that the collected EDID information (up to two pages) is correctly supplied to every connected computer, whether it is currently selected or not. See Figure 3-16.
