Auto Memory
The DVS 304 stores 16 auto memories with input and picture control data for each input. The default settings enables these memories to automatically recall input and picture controls for signals that have been previously applied. By disabling auto memories, the DVS 304 will treat every newly applied input as a new source. Default is on.

Aspect Mode
The aspect mode setting is global, and allows the user to select between each input signal filling the entire output raster (Fill), or for each input rate to be displayed with its native aspect ratio (Follow - default setting).
When in the Fill mode, if an aspect ratio adjustment for a single input rate is desired, the desired setting (4x3 or 16x9) can be made in the input config menu by adjusting the aspect ratio setting. If auto memories is enabled, then this setting is saved and recalled the next time the signal is detected.
It is strongly recommended that the aspect ratio mode setting be used on initial setup of the DVS, or input rates that have not already been saved as auto memories may not be displayed as expected. This can be overcome by clearing the auto memories on the input in question, and is done by holding in the front panel Menu button and the applicable input button simultaneously for four seconds. Alternatively it can be cleared on a rate by rate basis by applying a one time auto image.
