What would the advantage of getting a 640x480p resolution at 31.5 and 60 (negative pulses) be over displaying it on a TV? By default, the setting works fine on the monitor and does not on the TV. How did you determine what settings were ok for the Radeon card (i.e. what method did you use to determine what the resolution, porches, sync width, etc. should be in order to properly display on a compatible television)?
I have also heard through the grapevine that some folks have trouble with a store-bought transcoder (AA included) with powerstrip and their Radeon cards even after refering to your guide...so much so, that they also cannot get a 640x480 image to display. The reason I ask about your methods is to find what settings are ok (i.e. combinations of sync width, back and front porch, pixel clock, etc) together and what are not. I realize that each affect the total lines and that one would have to compensate one for the other but how do they interact? Also, are there cases out there where the total line had to be adjusted up or down a notch or two in order to get a proper display? Thanks, I'm just trying to understand.
