Extron electronics RGB-DVI 300 User Manual page 28

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 will be 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 carried out.
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.
Resets
To Reset all user settings, but keep the current version of the firmware, enter the menu,
select Advanced Configuration, and Factory Reset. Press and hold the Enter button until
the "Factory Reset" message is displayed on the screen. This is the same as the
E }
command ( ZXXX ), as shown on page 41.
Figure 19.
Factory Reset
To reset all options, including the original shipped firmware to the factory defaults, press and
hold the Enter button while applying power; the "Firmware Reset" message is displayed on
the on-screen display.

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 Menu button initially changes the output rate
to 1024x768 at 60 Hz. On the next occasion power is applied to the unit while holding the
Menu 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/professional displays will accept 720p.
