Before using the EYGO specs, you might want to consider emailing the company for specs specific to your monitor. (You can damage it if you use settings out of your monitor's range.)

that would really suck!
http://www.telcointercon.com/Sync. - TTL, positive or negative. Monitor circuitry will
automatically determine and adjust for VGA Horizontal Scan - Frequency 31.5KHz nominal
Capture range-30.5~32.5KHz
Active video - full width display of video
signals with active video from 25 to 28usec.
Linearity - plus or minus 5%
Vertical Scan - Frequency 60/70Hz
Capture range 47~85Hz
The Horizontal range gives you the "H Clock" - 30.5-32.5 and the "V Clock" is the 47-85. I think I've used the dfault Pclock setting from the Advv read me text. Make sure you use the right specs for your monitor, toots!
