Auto-Image and Auto Memory
The Auto-Image and Auto Memory functions work interactively. Either function can be on or off,
giving four possible combinations.
Auto Image on and Auto Memory on — If the Auto-Image function is on, the input signal
is sized and centered to fill the screen. If the Auto Memory function is on, these parameters
are saved. The next time the unit encounters the same signal, the parameters saved by the
Auto Memory are applied automatically.
When all 64 memories are filled, the oldest is overwritten by new ones.
Auto Image off and Auto Memory on (default setting) — If the Auto-Image function is off, the
unit applies the values from the input lookup table. If no further adjustments are made, the Auto
Memory does not save an entry, since all the parameters already match the input lookup table.
However, if the user adjusts the input manually or carries out an Auto-Image, the new parameters
is automatically stored by the Auto Memory function. These parameters are recalled when the
input is detected again.
Auto Image on and Auto Memory off — Each new signal is compared with the values in the
input lookup table and an Auto-Image is carried out. However, the parameters are not saved and
the next time this signal is encountered, it is, once again, compared with the lookup table and an
Auto-Image performed.
Auto Image off and Auto Memory off — Each new signal is set up with the default values. An
Auto-Image is not carried out and the manually adjusted parameters are not saved by the Auto
Memory.

Output Rate Reset
When the output resolution is incompatible with the attached display, it is often difficult to get
an image. An additional reset mode allows the user to toggle between two almost universally
applicable output rates of 1024x768 at 60 Hz (XGA) and 720p at 60 Hz.
Applying power to the unit while holding the
1024x768 at 60 Hz. On the next occasion power is applied to the unit while pressing the
button, the output rate toggles to 720p at 60 Hz.
These values were chosen because most PC monitors with a digital input will accept an XGA
signal and most other consumer or professional displays accept 720p.
