I converted my dell mini 9 to run OSX with a 64GB SSD
and used an intel mac to upload OSX. I have been able to get everything to work except the ability to show powerpoint presentations via the VGA connector. When I connect to digital projectors the computer connects but the screen shows a number of vertical lines that vary in thickness and color that are also projected. When I disconnect the VGA cable, the computer screen goes blank for a few seconds and then shows the normal desktop again. I have checked and made sure that mirroring is off.
Does anyone have suggestions for correcting this problem??
