At 75 dpi, screen of 1024 x 728 pixels is the same as 13.65 x 9.71 inches.

To achieve higher quality of images you can save as file type 'JPEG' and select compression setting of 8 (high quality image).  


Expect around 20-30% loss of brightness from projection.

Turn off the lights directly above the screen. 

Optimal image size and resolution for Powerpoint:

-In pixels the slide ratio is equal to 1500px x 845px at 72dpi.

-In inches the slide ratio is equal to 20.833 inches x 11.736 inches at 72dpi.
