What you have is a downscan converter, you don't need to use any special modes to display on your TV. You need to turn scanlines off though, as thats probably causing the rolling.
: I have just brought a Jamma Cab with a 20" Monitor. I have connected the monitor to a PC-TV converter using the following wires from the scart lead 7 - Blue, 11 - Green, 15 - Red, 17 - Ground, 20 - Composite sync. (I got this info from Powerjaw posted on this message board)
: Using Mames -monitor arcade option I just get a small scrambled rolling picture in the top left corner, however I put this down to the converter as I get the same image when using Mames -monitor pal option on a pal TV.
: Using the converter with the arcade monitor and using mames default -monitor settings, (PC monitor) the picture looks great, but I can't stop the screen from rolling. (horizontally vertically and diagonally) After fiddling with various buttons for well over 3hours I have had the screen quite close, but I just can't seem to get it that last bit. The buttons I have been fiddling with are H Phase, V Shift, H Freq, V amp H Amp and V Freq.
: Is this correct? Is their anything else I can try.
: any information would be appreciated
: Thanks Mike
