Advanced Configuration

The Advanced Configuration menu configures global settings, including Test Patterns,
Blank, Freeze, Global Auto Image, Auto Memory, and Factory Reset.
The advanced configuration is activated by pressing the Menu button to display the main
menu, using either rotary encoder to select Advanced Configuration and pressing the
Enter button.
Figure 18.
Test pattern can be set to Color Bars, Gray Scale, Crosshatch, Alternating Pixels, Crop,
four different Aspect ratios, or Off. These patterns are used to configure the output signal.
Color Bar – Used to verify correct cabling/color decoding
at the display. Color saturation,cross-talk, and level can
all be optimized at the display using this pattern.
4x4 Crosshatch – Used for linearity, convergence, skew,
focus, and geometric adjustments of display devices.
Crop – Once the clocking on the display has been optimized
using the Alt. Pix pattern, the Crop is used to align the active
area on the display using H / V shift adjustments.
1.78 Aspect – Used as an overlay to size and center 16:9 inputs
(e.g. 720p) with 4:3 output rates (e.g. 1024 x 768) for proper
"letter box" display. Note: appears identical to the Crop pattern
for 16:9 output rates (e.g. 720p)
2.35 Aspect – Used as an overlay to size and center
anamorphic source material for proper "letter box" display.
Table 4.
NOTE: All aspect ratio patterns also include a 1 pixel wide crop pattern at the edge of
the video output raster.
When Blank is enabled, there is no video output (aside from the on-screen display).
When Freeze is on, the video output is a still picture of the last active frame.

RGB-DVI 300, RGB-HDMI 300, and RGB-HDMI 300 A Test Patterns
RGB-DVI 300 and RGB-HDMI 300 (A) • Configuration
16 – Level Split Gray Scale – Used for display brightness,
contrast, and grayscale adjustments.
Alternating Pixels – Used to set Total Pixels ("clocking") and
Phasing ("fine sync") on a display device; this should be used
prior to Crop.
1.33 Aspect – Used as an overlay to size and center 4:3 inputs
(e.g. 1024 x 768) with 16:9 output rates (e.g. 720p) for proper
"pillar box" display. Note: appears identical to the Crop pattern
for 4:3 output rates (e.g. 1024 x 768).
1.85 Aspect – Used as an overlay to size and center 35mm
theatrical film source material for proper "letter box" display.
