Accessing monitor geometry

[Mike Fuller]

I've recently upgraded to a B&W G3 running OS 10.3.4 and 9.2.2, with an 
Applevision 1710AV monitor. As well as the video cable, the monitor is 
attached via the ADB port.

When it was used on my 9600 running OS 9.1, I could access the monitor 
geometry via software. This is absent on the G3 from either 9 or 10 
preferences. The front controls on the monitor aren't as functional as 
the software option (eg, no convergence).

Is there any way of getting back software control?

Thanks,

Mike Fuller
