3-13 IN1404XT Video Scaler and Switcher • Operation
• Standard — For standard 1.33 inputs (also known as full screen).
• Anamorphic — Provides vertical image squeezing to accommodate
anamorphically enhanced DVDs (1.85).
• Wide screen — For wide 1.78 inputs (letterbox).
• Wider screen — For wider screen 2.35 inputs (narrow letterbox).
• Tomarama — Expands a 16:9 signal to fill a 4:3 screen (1.78). As it expands

To change the selected aspect ratio, use the Menu or buttons to highlight the
desired ratio and press the
Enter (and save) button.
Most VCRs and satellite receivers output a signal with a 4:3 aspect ratio. How this
signal is filled with video determines its aspect ratio. Figure 3-10 shows four
examples of different input aspect ratios in their native 4:3 format and as they
appear after scaling.
