3.7Working with PIP or Seamless Switching

PIP (Picture-in-Picture) and Seamless Switching are independent but related projector features that both utilize two image processing paths within the projector. In the case of Picture-in-Picture, this double processing enables you to display two different images simultaneously – typically a smaller “secondary” image within a large “primary” background. In a seamless switch, the double processing essentially occurs between displays so that a full image relayed from one source can smoothly transform into a full image from another source. This change can be virtually instantaneous, or slowed as desired so that the current image appears to dissolve or “fade” into the new image.

Options for enabling and controlling PIP and Seamless Switching all reside in the same menu. Note however, that because both features utilize the projector’s double processing capability, PIP and Seamless Switching cannot be used together. For example, fading a pair of PIP images into a new display from a different source is not possible.

For best PIP or Seamless Switching results, use two different signal types* as defined below. Do not mix two signals of the same type.

Signal Type	Description (Input Location)
#1	5 BNCs (RGBHV or YPbPr)
#2	DVI - I (analog or digital)
#3	Decoded signals (Input 3, Input 4, Composite video, S-Video, or any video
	signal via Input 1 BNC connectors or via an analog option card).
#4	Analog Option Cards
#5	Digital Option Cards
#6	Digital Option Cards

*HD interlaced sources are not recommended for the PIP window.

Other PIP or Seamless Switching tips to keep in mind include:

•When using two digital signals or one analog and one digital, each must be ≤ 165 megapixels.

•When using two analog signals, each must be ≤ 90 megapixels.

•Avoid using an interlaced source in the PIP window

•Seamless switching may affect image quality in some cases

Working with PIP f NOTE: To control the primary image, access all picture controls through the Main menu. To control the secondary (PIP) image, access picture controls through the Picture-in-Picture and Switching menu.

Use the first of six options in the PIP and Switching menu to enable and define how you want to use PIP.
