EDID on the DVI and VGA inputs
If you connect a computer graphics card or other source which uses DDC to discover the capabilities of the attached display, it will
automatically configure itself to the best settings when connected to the projector via DVI, HDMI or VGA inputs.
Otherwise refer to the documentation supplied with the source to manually set the resolution to the DMD™ resolution of the projector or the
nearest suitable setting. Switch off the source, connect to the projector, then switch the source back on again.
Using HDMI/DVI switchers with the projector
When using an HDMI/DVI source switcher with the projector, it is important to set the switcher so that it passes the projector EDID through to
the source devices. If this is not done, the projector may not be able to lock to the source or display the source correctly as its video output
timings may not be compatible with those of the projector. Sometimes this is called transparent, pass-through or clone mode. See your
switcher’s manual for information on how to set this mode.
Additionally, sources which use HDCP encryption may not display properly when connected to the projector via a switcher. Refer to the
switcher’s manual for more information.
