3.5.1 Miscellaneous Options
This menu holds several unrelated settings.
Auto Backlight On
turns on the backlight whenever
AC power is restored. This is normally checked.
Curtain Pattern
determines what the screen will
show when there is no source picture. You have a
choice of several solid colors or the Clarity logo.
Turn Backlight Off With No Source
saves electricity
and backlight life. When the source is restored, the
backlight turns on again.
Ignore RS232 CRC
means that RS232 commands
will be accepted whether they have the correct CRC
check sum or not.
Enable Image Orbiting
moves the image by one
pixel-size at a time to prevent or alleviate temporary
image retention .
When a high-contrast, still image is displayed for a
long time on Bay Cat, it sometimes happens that the
image is retained temporarily. To recover from this,
display a black picture, such as the black test pattern,
for a while until the retained image can no longer be
seen.
If still pictures are unavoidable, reduce the possi-
bility of temporary image retention: turn on image
orbiting.
This moves the picture in 9 positions, each posi-
tion only one pixel from the next. It has the same
effect as using the position control to move the pic-
ture.
How does orbiting occur? These are the 9 pixel
positions:
When image orbiting starts, the picture is assumed
to be in position 5. It moves to position 1, then
moves to each position in the order shown. The pic-
ture stays in each position for 30 seconds.
Clear Input Memory
erases the 10 input memories
for a fresh start.
When a new mode is encountered, the Bay Cat
adjusts to it and saves those settings in a memory. As
input pictures with different modes are sent to the
analog or DVI input, the Bay Cat uses the values
from this memory, if the values for the new source
are close to values already stored.
This saves time, because the Bay Cat does not
have to go search through the mode table and adjust
to the frequency and phase of the new signal.
However, when the new source is close to but not
quite exactly like a previous source, the Bay Cat may
chose a set of values from the memory that are not
correct. The picture may be cut off on one edge or too
small for the screen.
If this happens repeatedly, select
Clear Input Mem-
ory
and press
ENTER
.
