6.3 Using dual head input
For extended flexibility to connect high resolution sources with a pixel clock over 165 MHz,
the projector is supporting a dual head input mode. In this mode the left and right half of the
image can be connected to the DVI 1/DVI 2 or HDMI 1/HDMI 2 interfaces respectively
(Figure 6-1).
To enable this mode, go to the menu INSTALLATION > DUAL HEAD SETUP. Side-by-side is
the only available option at this time.
Figure 6-1. Dual input mode
An example of this is feeding a WUXGA (1920 x1200) 120Hz source with 960 x 1200 -
120Hz source resolutions on each the DVI interfaces.
When enabling this mode, the EDID data on each of the DVI connectors will automatically be
changed from WUXGA (1920 x 1200) 120Hz to 960 x 1200 - 120Hz.
For the image to be displayed in this mode, the resolution must be exactly the same
on both connectors.
In this mode the two connected sources must have exactly the same timing. A drift in
timing between the inputs will result in a visible split in the center of image.
Some graphic cards have problems with detecting the change from single head to
dual head mode. If problems occur, disconnect both signal cables before enabling or
disabling the dual mode in the menu.
