A:Answer Thank you for your interest in the UHD38X projector. Based on the request, "Can I change the aspect ratio of the image.. my screen will be 10ft x 10ft for a golf simulator" The diagonal for a 10ft by 10ft screen would calculate to a 170" diagonal projection and the placement of this projector will be between 22'-8" up to 25'-1".
