Initial Setup − Step By Step
The setup sequence for typical configurations is shown below. See the Command Format section
(page 7) for information on entering commands. Typically, not all commands shown here are
needed. Only the most common setup commands and options are shown in this section. See the
Installation Commands section (page 14) for additional commands and options.
Initial Output/Input Setup:
• Connect video cables as described in the Rear Panel section. Then connect power and turn all
required components on.
• Select the output type: Skip this step if a DVI-D/HDMI display is connected. If a DVI-D display
is connected, DVI-D will be selected by default, otherwise analog RGBHV output is the default.
For analog output, the mode can be changed as shown below. For more info see the Output
Configuration Section (page 14).

• Set vertical refresh rate: Skip this step if the output rate is to be 59.94 (U.S.A and some other
countries). The default vertical refresh rate is 59.94, but it can be changed to be from 23.98 up
to 120 Hertz. The maximum rate varies depending on the resolution.
MENU 0 4 value OK Value is in hundredths (e.g. 59.94 is 5 9 9 4)
• Set output resolution: The output resolution defaults to 480p, with 480 active scanlines in
progressive format. A different output resolution can be selected using the menu or by direct
command. The menu command is:
MENU → OUT → RES → VRES → value OK
The direct commands to select output resolution are:
480p: MENU 0 2 1
540p: MENU 0 2 2 600p: MENU 0 2 3
720p: MENU 0 2 4 768p: MENU 0 2 5 840p: MENU 0 2 6
1080p: MENU 0 2 7 1080i: MENU 0 2 8
Other: MENU 0 3 value [ˆ,‡] OK, where ˆ is interlaced and ‡ is progressive (default).
• For digital displays using the DVI-D input (skip this step for displays using an analog input), it
is important to operate the display at their native resolution to achieve a “pixel-perfect” image.
This maximizes the Lumagen’s video processing advantages by disabling the display’s internal
processing. Some displays do not support their native resolution as an input, or do not operate
in “pixel-perfect” mode even when they are driven at their native resolution. Consult with the
display’s manufacturer for more information on if the display can achieve a pixel-perfect image.
• Set the horizontal resolution. Skip this step for analog output, or if the default HRES selected
by the Lumagen for user selected VRES is correct. The command is:
MENU → OUT → RES → HRES → value OK
•
Some DVI-D/HDMI displays can achieve a “pixel-perfect” image, but require specific pixel
timings for all parameters, not just active pixel counts (skip this step for displays using an analog
input). Lumagen video processors can accommodate these displays using the TIMING command.
