3.1 Recommendations for Best Performance
To achieve the best performance:
Connect only good quality connection cables, thus avoiding
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 and
position your HDMI distributors away from moisture, excessive
sunlight and dust

6.1 Acquiring the EDID
The VM-8H 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:
One Output (the selected output LED illuminates)
The Default EDID (all the output LEDs flash)
Several connected outputs, the Auto-mix Mode1, (the output
LEDs flash in sequence)
To cycle between the different modes (One Output, Default and Auto-mix),
press the SELECT button, as defined in Table 2.
Table 2: The EDID Modes
To acquire or change the EDID of a new output display from:
One output, see Section 6.1.1
The default EDID, see Section 6.1.2
Several connected outputs, see Section 6.1.3
6.1.1 Acquiring the EDID from one Output
To acquire the EDID of a new output display, do the following:
1. Press the SELECT button.
The currently selected OUTPUT LED illuminates.
2. Press the SELECT button again to cycle from one output to another
until reaching the desired output.
3. Press the READ button.
The flashing ceases and the button illuminates. The VM-8H accesses
The EDID acquired is a weighted average of all the connected outputs. For example, if several displays with different
resolutions are connected to the outputs, the acquired EDID supports all the resolutions, as well as other parameters included
in the EDID

6.1.2 Acquiring the Default EDID
To acquire the default EDID, do the following:
1. Press the SELECT button.
The OUTPUT LEDs flash simultaneously.
2. Press the READ button.
The flashing ceases and the button illuminates. The VM-8H accesses
the default EDID.
The EDID of the selected output is stored in the non-volatile memory
when the READ button no longer illuminates.
6.1.3 Acquiring the EDID from Several Outputs
To acquire or change the EDID via several connected outputs, do the
following:
1. Press the SELECT button.
The OUTPUT LEDs flash in sequence.
2. Press the READ button.
The flashing ceases and the button illuminates. The VM-8H accesses
the EDID of the connected outputs.
The EDID is stored in the non-volatile memory when the READ
button no longer illuminates.
