2.7 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.

Note:

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.
