3.6.3 Miscellaneous Options
This menu holds several unrelated settings.
To access the Auto Setup Options menu, on the remote,
press
twice.
MISC
Curtain Pattern determines what the screen will show
when there is no source picture. You have a choice of sev-
eral solid colors or the logo.
Auto Codes when checked, automatically turns on the on-
screen code LED indicator when there is an error. The LED
will start blinking on the screen immediately when any
event occurs that forces the backlights off.
Plug and Play (EDID Enable)
For Plug and Play and EDID, see the full discussion in
"EDID: What It Is and How It Works" on page 131.
Preferred Source Detection
Analog computer video cards provide only vertical and
horizontal frequencies. Sometimes, this is not enough
information. GX40 receiving such "ambiguous" signal
modes, in certain cases, could misinterpret the resolution to
be any of three different modes. For example, 1024 x 768,
1280 x 768, and 1360 x 768 all have the same respective
horizontal and vertical frequencies but represent different
aspect ratios, 4 x 3, 15 x 9, and 16 x 9, respectively. By
specifying the correct source detection mode, GX40 can
correctly interpret the signal and display the incoming
image in the proper aspect ratio. The native aspect ratio of
GX40 is 16 x 9, and the default resolution is1366 x 768.
HD Interlaced Content Motion
HD Interlaced Content Motion is a control you probably
won't need to touch. Here is an explanation of it.
Some video signals, most notably those made for televi-
sion, are what is known as "interlaced". At one moment in
time, only the even number lines of image are transmitted
to the display. At the next moment (usually 1/30 or 1/25 of
a second later) the odd numbered lines are transmitted.
These two moments in time are known as fields. On CRT
television sets, the even field persists on the phosphor long
enough so that by the time the odd field gets there, our eyes
put it all together into one picture. If the image is static,
such as with computer graphics, it is quite simple to put the
fields back together. However, if the image is moving, it
can cause problems because an image will have moved
from the time the even lines arrive to when the odd lines
arrive. A special piece of electronics known as a deinter-
lacer can analyze whether an image is moving or stationery
and use mathematical algorithms to put the two image
fields together in the best way. The GX40 has deinterlacer
electronics to take care of standard definition television sig-
nals. However, it does not have deinterlacer circuitry for
high definition television (1080i). The "HD Interlaced Con-
tent Motion" control gives the regular electronics some
help in determining how to put together the two fields if
you are viewing 1080i. Keeping this setting at "Normal"
works best for most images. This will assume the image has
no fast motion. The only time you will see a problem with
this setting is if you are at native resolution (i.e. you are
using a Baycat X or your scale mode is set to one to one on
a Bobcat X). In that case, you may see something of a "zip-
per" effect on the edge of moving objects. To get rid of this,
change the setting to "Rapid". However, if you do, you will
probably see static images flickering slightly (known as
"twittering").
✎
Another alternative to minimize both effects is to
keep the setting at Normal and set overscan (in
the Aspect Ratio menu) to 1%. This will turn on the
scaler and minimize the zipper effect.For more
