3.2Output Screen Aspect Ratio

3.2.1Output Screen Aspect Ratio (Multiple) (Not Available from IR remote mouse)

The Output Screen Aspect Ratio control interacts with the Output Display Device Configuration and Input Aspect Ratio Selection to position the scaled and process image in the best screen position for a given combination. It is important to remember that the Screen aspect ratio is different from the Display Device aspect ratio. (for example, using a D-ILA projection system with a display device resolution of 1365 x 1024, aspect ratio of 4:3, a user may optimize his projection room for 16:9 viewing by focusing the projector on a 16:9 screen. This will effectively reduce the resolution of the projection system to 1365 x 768. The pixels outside the 1365 x 768 viewing area are still active (although black) and may be focussed into the floor or the ceiling to achieve the desired maximum viewing area at 16:9. Since the exact position of the 1365 x 768 “active video” window within the 1365 x 1024 raster of the D-ILA is not known, 3 position settings are provided:

A)positions the 1365 x 768 active video strip at the top of the 1365 x 1024 raster.

B)positions the 1365 x 768 active video strip in the middle of the 1365 x 1024 raster.

C)positions the 1365 x 768 active video strip at the bottom of the 1365 x 1024 raster.

When 16:9 Output Aspect Ratio is selected, the QuadScan will determine the best presentation of the image upon a 16:9 screen based also on the Display Device Resolution and the Input Aspect Ratio selected. Similar action will be performed for 4:3 aspect ratio screens if 4:3 Output Aspect Ratio is chosen. The choices of Output Screen Size are:

Output Aspect Ratio

Front Panel Designation

16:9 Top

16:9A

16:9 Middle

16:9B

16:9 Bottom

16:9C

4:3 Top

4:3A

4:3 Middle

4:3B

4:3 Bottom

4:3C

The Output Aspect Ratio Control default is 4:3B. The Output Aspect Ratio Control is restricted to 4:3B for all input modes of 800 x 600 and less.

3.3Reset and Control Functions

3.3.1IR ON/OFF (Toggle) (Not available from IR remote mouse)

This control enables/disables IR Remote Control.

3.3.2Mode Reset

This control resets the current mode to its factory default. Each “mode” is defined as being a Input Source-Output Resolution combination. (For example, PAL composite input on Channel B scaled to XGA output is one mode). The Mode Reset control affects only the current mode, all others will remain as previously configured by the user.

3.3.3Full Reset (Not available from IR remote mouse)

This control resets all of the modes of the QuadScan to their factory default values.
