Screen Saver and Timeout
— This item lets you enable screen saver mode, in
which the video output is muted to black or blue if there is no active input video
signal. It also lets you specify the output sync timeout. Screen saver mode allows
display devices (such as an LCD panel, plasma screen, or projector) to enter low
power or standby state to increase panel or lamp life.
•
To select the screen saver color, press the
t
or
button. The options are
Black
(default) or
Blue
.
•
To set the sync timeout, press the
or
button. You can select a duration of
1 through 500 seconds before the output sync times out. The default is
Never
,
meaning that the sync does not time out.
NOTE:
The DSC exits screen saver mode when a front panel button is pressed
or an active input is detected. If the unit is in front panel lock (executive) mode
(see
Locking the Front Panel (Executive Mode)
on page 39), front panel
button presses have no effect on screen saver mode.
•
Aspect Ratio
— This item lets you set the aspect ratio to
Fill
(fills the entire output
screen) or
Follow
(follows the native aspect ratio of the input).
•
In fill mode
, if you want to set an aspect ratio adjustment for a single input
rate, you can select the correct size and position manually from the
Picture
Controls
submenu (
Image
Size
and
Position
on page 21).
•
In follow mode,
each input rate is displayed with its native aspect ratio (4:3,
5:4, 15:9, 16:9, 16:10) with the correct letter box or pillar box settings, visible
under the
Image
Size
and
Image
Position
items on the
Picture
Controls
submenu.
If you want a single input to fill the screen in follow mode, you can manually set
the
Image
Position
item on the
Picture
Controls
submenu to
0,0
and set
the
Image
Size
to match the current output rate
X,Y
.
•
Auto Memory
— This item lets you enable or disable Auto Memory. When Auto
Memory is enabled, the DSC stores the current input configuration and picture control
values as an input preset. All values are stored except preset name, film mode, and
audio gain or attenuation (see
on page 37 for more information).
•
Overscan
— This item lets you select a default overscan mode to apply to SMPTE
input rates (480i, 576i, 480p, 576p, 720p, 1080i, 1080p, and 2K). This zooms and
crops SMPTE inputs to mask edge effects and ancillary data that may occur in
broadcast signals. The selections are
0%
(the default),
2.5%
, and
5%
.
NOTE:
If the overscan mode is not 0%, when Auto-Image is performed on an
SMPTE input rate, it refers to the default input values for sizing and centering
instead of performing a true Auto-Image.
•
Temperature
— This read-only field shows the internal temperature of the unit in
Fahrenheit (left value) and Celsius (right value).
•
Factory Reset
— This item lets you reset the unit to its factory-installed values
(removing any user-defined values) while retaining the current firmware version.
To reset using the OSD, press and hold the
Enter
button until
Factory
Reset
is displayed. The message remains for approximately 1 minute after the reset is
complete to allow time for the display device to sync with the DSC output. (The
equivalent SIS command is <
ESC
>
ZXXX
<
]
>.) For other reset methods, see
on page 39.
