4.1 Stereo Source Specifications
Stereo Source Specifications
•
Maximum Vertical frequency is 110 Hz.
•
Maximum Horizontal Frequency is 113.63 KHz.
•
Pixel clock of incoming signal must exceed 150 MHz and be lower than 205 MHz.
•
The Active number of pixels has to be 1280x1024 for stereo operation.
4.2 Running in Stereo Mode
When does the projector run in Stereo Mode ?
•
It is possible to program a Turnover frequency for the BARCO Galaxy projector, when a source is detected with a vertical
frequency that exceeds this Turnover point the projector will switch from Mono Mode to Stereo Mode.
•
Going in Stereo Mode will enable Stereo Phase, Invert Stereo and the Stereo Timings menu, at the same time the Geometry
Adjustment menus and Gamma Menu are disabled.
Why distorted images in Stereo Mode when selecting a menu ?
As soon as you select a menu when running in Stereo Mode, the projector switches back to Mono Mode to enable the on screen
display generated by the PMP. As a consequence, the stereo image might look a little bit distorted, this is normal as the PMP cannot
handle such a high bit clock.
Rudimentary Barscale in Stereo Mode
When running in Stereo Mode an rudimentary barscale is displayed in the Bottom Right corner.

Rudimentary Barscale in Stereo Mode
Pressing the ? key on the RCU or Local Keypad will force the projector to run in Mono Mode and will display
the more detailed bar scale as displayed in Mono Mode, however since this is generated by the PMP a distorted
stereo image will occur. Use the ? key to return to Stereo Mode.

4.3 Quick Stereo Set Up
How to set up a Stereo Source ?
1. Connect the Image Generator and Stereo Emitters to the projector(see chapter 5. Connections, Input 1 & 2, page 23)(see chapter
5. Connections, Left/Right Phasing module (Input 3), page 25).
2. With the File Load menu you have to select a memory block that matches your source as close as possible. (some standard
source are already on board e.g. SGI_108 and SGI_110 other will follow)(see chapter 8. Random Access Adjustment Mode,
Load file, page 40).
3. Edit the memory file and set the total and active number of pixels both horizontal and vertical to the appropriate values(see
chapter 8. Random Access Adjustment Mode, Edit File, page 41).
4. Select the second page and adjust the clamping delay and width (these values will be lower compared to standard mono
sources)(see chapter 8. Random Access Adjustment Mode, Correct value, page 42).
