3.6 Video Timing Parameters
The Borealis must be programmed to generate the proper video timing for
the hardware configuration and display format. Rastergraf ’s SDL
subroutine library package accepts display format (e.g. 1600 x 1200, 32
bpp) and refresh requirements (e.g. 67 Hz vertical refresh) as parameters
to a function call. The software then provides (and loads) a best fit timing
profile for the Borealis graphics chip.
Similar display format information is provided in a configuration file for
Rastergraf ’s PX Windows server.
Does your Display have a Green Cast to it?
By default, the Eclipse3 supplies video in separate (five wire video
RGBHV) video format. If you hook the Eclipse3 up to a multiscan
monitor with a regular VGA cable then you will be giving RGBHV to the
monitor. Be sure to not select sync-on-green in the Eclipse3 video
parameters or you will get a green cast to the image.
