well I tried finding those entry in the registry but could not find it with The find option. I bought another dvi to vga adaptor and this one works somewhat the screen keeps rolling fast up and down. I got the drivers working by booting with my pc monitor and then swapping with the arcade monitor and it works beatifully but on the dvi port I get the screen rolling even with the composite sync option on ATI catalyst. what can I do my arcade monitor only has 5 wires. red, green, blue, black and white cables. should I make a jumper between pin 14 and 13?
