5.2Aspect Ratio

TheaterSync provides five different aspect ratio treatments. The operation mode of these treatments depends on the aspect ratio of the input channel and the output display.

The TheaterSync assumes that the aspect ratio of input and output is consistent with the industry standard definition of the aspect ratio of the particular input signal and video mode. Output aspect ratio is thus determined by the resolution selected by the user in Setup Mode. Input aspect ratio is determined by the TheaterSync video mode recognition circuitry. Only two output aspect ratios are supported, 4:3 and 16:94.

3Default for DVI and Analog RGB inputs.

4The special case of 1280 x 1024 SXGA (an aspect ratio of 5:4) on output is treated as if it were 4:3. The output of a 1280 x 1024 display will be slightly distorted; circles will appear to be vertically oriented ovals. Since the
