Setting Up the DSC HD-HD 4K A Using the OSD Menu
The
Quick
Setup
submenu is displayed when the OSD opens. This submenu contains items that you are most likely to need
when configuring the DSC for the first time. To perform a basic system setup to get started, select the following items as needed:
z
Input EDID
— Select an input EDID (resolution and refresh rate) to match the output rate or set a discrete EDID. The default
EDID is
Auto
(match the current output resolution).
z
Output Rate
— Select the scaler output resolution and rate from 66 available factory-installed rates (see output rates table,
below). You can also select one of three custom slots to add a user-defined resolution. The default rate is 1080p @ 60 Hz.
z
HDCP Authorized
— Select whether the input will report to a source as an HDCP-authorized device, thereby allowing
HDCP-encrypted content (
On
), or will block input encryption (
Off
). The default is
On
.
z
Auto Memory
— Set the DSC to automatically save and recall the current input configuration and picture control values for
each detected input resolution. After selecting
Auto
Memory
, press any arrow button to toggle Auto Memories on and off.
The default is
On
.
z
Aspect Ratio
— Configure aspect ratio compensation. Selections include
Fill
(inputs fill the entire output raster) and
Follow
(maintains the native aspect ratio of the input signal). After selecting
Aspect
Ratio
, press any arrow button to
toggle between
Fill
and
Follow
. The default is
Fill
.
z
Test Pattern
— Select from six test patterns to aid in setting up the DSC and the output display. Available test patterns
include
Crop
,
Alternating
Pixels
,
Crosshatch
,
Color
Bars
,
Grayscale
, and
Audio
Test
. The default is
Off
.
z
Output Audio Format
— Select
between stereo and dual mono. The
default is
Stereo
.
Locking the Front Panel
To prevent unauthorized access or
accidental changes to DSC settings, you

executive mode), enter
1X
. To unlock
(disable executive mode), enter

.
Output Scaler Rates
Output rates can be set using the OSD
menu or SIS commands. The table at
right gives the rates and their SIS variables
(see the
SIS table
on the next page).
Output Rate Reset
If an image cannot be displayed due to an
incompatible output rate, you can reset the
output rate as follows:
With the OSD
off
, press and hold the
button for approximately 5 seconds to
toggle between 1024x768 @ 60 Hz and
720p @ 60 Hz.
