2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VM-4DP away from moisture, excessive sunlight and
dust

6 Acquiring an EDID
The VM-4DP initially operates with the default EDID. This means that you can turn ON
the power before connecting any of the acceptors or the source.
You can acquire the EDID from:
The default EDID, see Section 6.1
A connected output, see Section 6.2
6.1 Acquiring the Default EDID
To acquire the default EDID, do the following:
1. Press the SELECT button, as required, to reach a disconnected output.
The selected output LED flashes.
2. Press the READ button.
The READ button flashes.
The new EDID of the selected output is stored in the non-volatile memory
and passed to the input when the READ button no longer flashes.
6.2 Acquiring the EDID from a Connected Output
To acquire the EDID, from a selected output, do the following:
1. Press the SELECT button, as required, to reach the desired connected
2. Press the READ button.
output from which you want to acquire the EDID.
The selected output LED flashes.
The READ button flashes.
The new EDID of the selected output is stored in the non-volatile memory
and passed to the input when the READ button no longer flashes.
