The best projection distance of the projector
In the purchase of the projector, we first noticed the projector brightness, resolution, contrast, uniformity and other important parameters, in addition, we should also make clear the focal length and liquid crystal projector parameters such as size, suitable for use in the field to our projection distance and screen size, screen size and projection distance is closely related with the the focal length and liquid crystal projector dimensions, following their relationship：
The known picture size get the projection distance：
Minimum projection distance（m） = Minimum focal length（m）x Picture size（inch）÷LCD size（inch）
Maximum projection distance（m） = Maximum focal length（m）x Picture size（inch）÷LCD size（inch）
The known projection distance get picture size：
MaximumPicture size（inch）= projection distance（m）x LCD size（inch）÷Maximum focal length（m）
MinimumPicture size（inch）= projection distance（m）x LCD size（inch）÷Minimum focal length（m）
