In regards to my Mac Quicksilver not sending any video signal: Jo Hissel said First try another monitor. I hooked my wife's laptop up to the monitor, and it works. I have yet to try Dale's suggestion to replace the p-ram battery. Thanks for the suggesions. Jack Law jlaw51 at verizon.net __________________________________________________ Do You Yahoo!?
