Mac Book display through projector
i m using a Mac BooK with snow leopard,,,normally when i connect my mac to the projector, the image display normally...since i choose mirror effect so that it is exactly the same what my mac book show on the screen and the display of projector. But I don't know why that recently when i connect to projector to show my keynote and ppt file in fullscreen mode...the projector show normally and my mac book screen is so horrible with all the colour grid and just like the damage television!!! But the the image for projector still seem normally and show my ppt or keynote presentation....and it only happen with the ppt or keynote full screen mode.
