- Summary: Some control codes for the Q700
- Keywords: Random info
- Lines: 25
-
- Just a little information I found messing around with _Control and
- _Status codes. If you have a multisync monitor but no software to
- change the resolution, this might come in handy.
-
- To make the Q700 built-in video come up with the monitor in the mode
- you desire, make a _Control call, cscode=9, csParam = &shortvar, with
- shortvar = to something from this little table:
-
- C325: 12" monitor (512*384)
- C925: 13" monitor (640*480)
- C725: 16" monitor
- CB25: 640*480 VGA
- EB25: 800*600 SVGA
-
- There are other values for all the other supported resolutions. The
- way the hardware seems to work is it checks the sense lines. If the sense
- lines are the same as last time, it comes up in the mode it was set
- to. If they have changed, it comes up in the default mode for the new
- sense lines. This means that no matter what the sense lines say, you
- can set the video mode to something else.
