Most source devices send an electronic inquiry to the display asking
for informa on about it’s capabili es. The display sends a table of
informa on called the Extended Display Iden fi ca on Data (EDID).
Using this informa on, the source device changes it’s resolu on to
match the na ve resolu on of the display or some other resolu on
that is supported by both source and display.
The PS100 intercepts the display’s response to the EDID table request and sends its own EDID
informa on to “trick” the source into sending it’s content in a par cular resolu on and/or audio
format. This method allows us to change the resolu on of the source device without reprocess-
ing the video image and degrading the quality of the na ve image.
The EDID Resolu on Select rotary dial can the modifi ed using a standard screw driver to change
the EDID table informa on being sent to the source device.

0 Copies the EDID information from the display and makes it available for quick
access to all Source Devices. Information is extracted at the time the PS100
is powered up. The display must be powered but does not necessarily need to
be operating in order to obtain the display information.

all four Active Source Indicators fl ash one time, EDID copy (option 0 above)
