Step 6. After four seconds, the LED will stop flashing and will remain on for about two seconds. During this time the
EDID data is being captured.
Step 7. Once the external capture is complete, the LED will again flash, but more slowly than before. At this point,
release the switch.
Step 8. At Mac Displays Preference window, click Detect Displays button. The computer will re-sync the outputs
and the new EDID will be applied. (You can connect your display devices at this point.)
Step 9. You should have a viewable resolution on the output that you were reconfiguring. You may still need to
change this resolution (using the Displays Preference window) to a specific desired resolution.
Step 10. Perform steps 1 - 7 on the other output section of the I/O module.
SDI Output (SD - Standard Definition & HD - High Definition)
IMPORTANT! This requires connection to a Dual I/O Module. If you are using Mbox Designer without the Dual I/O
Module, you will not be able to output SDI.
The Mbox Designer software supports SD/HD-SDI output directly from the Dual I/O module without need for a scan
converter. SDI can be sent from both outputs of the I/O module simultaneously. A standard DVI monitor may need to
be connected to the Preview output(s) of the I/O module so that the Mac desktop can be viewed when Mbox Designer
is not running in Fullscreen mode.
In order to output SDI, the Mac Graphics card must be set to display output resolutions and frequencies that some
DVI monitors may not support. The EDID spoofing built into the Dual I/O module allows the unit to output the special
resolutions and frequencies.
In order to output SDI, Mbox Designer simply needs to be configured to use the appropriate Fullscreen mode setting
and the Dual I/O module will automatically output SDI at that resolution and frequency setting (refer to
"Connected
Display Devices and EDID" on page 67 for further info on frequency settings).
When SDI has been enabled, normal VGA or DVI monitors connected to the Dual I/O module may not be able to
display a picture. DVI monitors provide the most compatibility, but compatibility is not guaranteed. However, the two
SDI connectors (A & B) on the face of the module do act as Preview and Stage SDI outputs. SDI A will be the Stage
output, and SDI B will be the Preview output. In this way, an SDI monitor can be used with the SDI preview output.
Note: Most SD-SDI monitors cannot display an HD-SDI signal, but HD-SDI monitors can display SD-SDI signals.
When entering the Fullscreen mode with Mbox Designer set to output an SDI-compatible resolution, the SDI indicator
LED to the left of SDI connector A will illuminate. SDI will be output if one of the pre-determined SDI settings is
selected or if the Custom mode is configured with a resolution and frequency that matches one of the possible SDI
formats.
When using SDI output, it may not be possible to run the Mac desktop at the same resolution and frequency as the
selected (SDI) Fullscreen mode. If also using Genlock, this means that genlock sync will be lost when switching
between Fullscreen and Window modes or when quitting the Mbox Designer software (see
"Setup: Fullscreen Mode"
on page 58 for more information). In this case, plan accordingly to enter Fullscreen mode with enough time to allow
the genlock to sync.
The following SDI resolutions are supported:
+ SD - NTSC 480i (720 x 480) @ 60Hz (non-square pixels)
+ SD - PAL 576i (720 x 576) @ 50Hz (non-square pixels)
+ HD - 720p (1280 x 720) @ 59.94/60Hz
+ HD - 1080i (1920 x 1080) @ 50/59.94/60Hz
+ HD - 1080p (1920 x 1080) @ 23.98/24/25/29.97/30Hz
