•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 the signal, it cuts off the left and right sides, simulating the movie aspect ratio “Cinemascope”.
