EDID Manager

Extended Display Identification Data exchange is a standardized means for a display to communicate its capabilities to a source device. It enables the VPU to know what kind of monitor is connected. The EDID includes manufacturer name and serial number, product type, phosphor or filter type, timings supported by the display, display size, luminance data and (for digital displays only) pixel mapping data.

Unfortunately some LED walls offer no EDID data, so the VPU software cannot offer the correct resolution and refresh rates. Or if a monitor is reconnected the right resolution and refresh rate has to be set again.

To avoid these troubles the DVI outputs of the VPU have been equipped with additional hardware. An EDID Chip offers the common resolutions and refresh rates to the VPU hardware.

The switch near the DVI OUT connector lights blue if EDID is simulated.

If VPU is turned on and only output 2 is connected (EDID signal found) this output gets the logical output 1. If now a second monitor is connected to output 1 (or EDID 1 is switched on) this will be assigned to logical output 2. This situation can be undone if VPU is restarted with only on monitor (or EDID signal on) on output 1.

The EDID chip offers the following DVI resolutions and refresh rates. Other values are invalid:
