QuickSwitch HD™ HDMI Switchers Crestron HD-MD8X1/2

• Best Common

Best Common

Only resolutions that are available in all of the displays that are connected

will be transmitted to the source. This ensures that any video signal coming

in from the source will be able to be shown on all displays. If certain

resolutions are only available on a subset of the displays, they will be

omitted.

• Manual

Use Crestron Toolbox to select which resolutions are transmitted to the

source.

“Best Common” is initially set to use information from all displays, but can be

modified to use information from just a subset of displays by deselecting them in

Crestron Toolbox.

By managing which displays are used for the EDID calculations, you can maximize

the resolution of each source while ensuring that the source can be shown on each

display where it is needed.

The EDID calculations also affect audio formats. Each HDMI receiver sends its

supported audio formats to the source in the following format:

For example, a 5.1channel audio processor may have the following audio EDID

information:

• Linear PCM, 2ch, 32/44.1/48kHz

• AC3, 6ch, 32/44.1/48kHz

• DTS, 6ch, 32/44.1/48kHz

Under “Best Common”, the same rules apply to audio as video.
