Appendix D—Additional Resolution & Graphics Display
Information
To understand how an image is scaled from the QSX unit’s VGA output to another
device, refer to the following table:
Transmission Scaling
QSX Output Resolution No Scaling Scale to 800x 600 Scale to 640 x 480
640 x 480
640 x 480 640 x 480 640 x 480
800 x 600
800 x 600 800 x 600 640 x 480
1024 x 768
1024 x 768 800 x 600 640 x 480
1280 x 1024
1024 x 768 800 x 600 640 x 480
In this table, if you wish to scale VGA output of the QSX from, for example, 1024x768
to 800x600, the resulting scale will be 800x600.
Note: If the resolution of the VGA Output is configured at 1280x1024, the images will
automatically be scaled to 1024x768 for transmission.
Note: The QSX supports local display output resolutions of 1280x1024, 1024x768 and
800x600, but not 640x480. If the output device supports DDC, the highest resolution
will be first selected. If output device does not support DDC, a 1024x768 resolution will
be used.
Note: The QSX output scaling option takes effect after the next presentation starts. If the
option is changed when the QSX is in presentation, it is required to stop presentation and
start again.
When the QSX displays a remote image, it will always scale the decompressed image to
its own local display resolution. The resolution can be one of the following three
resolutions:
• SXGA (1280 x 1024)
• XGA (1024 x 768)
• SVGA (800 x 600)
