MBOX ® MEDIA SERVER USER MANUAL 45
Setup: Fullscreen Mode
The Fullscreen Mode section is used to set the native
resolution, frequency, and aspect ratio of the stage display
device being used. It is not uncommon to change the
Fullscreen Mode settings since, for example, a standard
definition projector would require different settings than an HD
projector, etc.
Getting the desired results from any Fullscreen mode setting
requires the computer to be receiving EDID information that
matches the Fullscreen mode settings. If no EDID is present or
if the EDID does not match the setting entered here, MBOX
Designer will not output the desired resolution and/or frequency when the software enters Fullscreen mode. Always
confirm that you have the appropriate EDID before using the MBOX Designer software. The MBOX Dual I/O Module
provides EDID data to the computer at all time, but if you are using MBOX Designer without the I/O Module, you will
need to supply the appropriate EDID by connecting the output device (or some alternate EDID spoofing device) to the
computer's video output(s).
If one of the standard modes is selected (e.g. SDI 720p), the resolution, frequency, and aspect values will be
automatically set to match. If the custom mode is selected, then these values will need to be manually adjusted.
All video output connectors on the Dual I/O module will output a signal with the same resolution, frequency, and
aspect ratio. The only exception being the SDI outputs which will not output signal if the Fullscreen mode is not
compatible with a standard SDI format.
The Fullscreen mode settings will also be applied to the video signal that is output from the Preview connectors on the
Dual I/O module. Ensure that the preview monitor is able to display an image when receiving a signal with that
resolution and frequency. If the native aspect ratio of the monitor does not match that of the Fullscreen mode, then it
may still display an image, however, it will have the wrong aspect ratio.
Above all, it is more important to tailor the Fullscreen mode settings to the stage device, than to the preview monitor.
The Dual I/O module will not allow output resolutions to be set that may not work with some preview monitors. The
most likely case being when SDI output is used - see
"SDI Output (SD - Standard Definition & HD - High Definition)"
on page 57 for further details.
When a certain resolution setting for Fullscreen mode is requested, the operating system will review its EDID
information to see if it is capable of that configuration. If a resolution is requested that does not match a resolution
listed in the current EDID set - see
"Connected Display Devices and EDID" on page 53 for further details - there are
two possible outcomes:
+ If the EDID set does not have any resolutions that are higher than the requested setting, the operating system will
pick a resolution from among those in the current EDID set. In this situation, MBOX Designer has no control over
what resolution the operating system provides.
+ If the EDID set does have higher resolutions, then the next highest available resolution with a similar aspect ratio
will be used and the selected fullscreen resolution will be inserted in the bottom-left corner of the screen, inside
the higher resolution. The extra screen area outside the requested fullscreen dimension will be rendered in black
and will not allow content to be placed there. As in the prior case, MBOX Designer has no control over the actual
resolution that the operating system provides. (See "Active Area Controls" section below for further information.)
CAUTION! It is strongly recommended that the Mac desktop resolution and refresh rate (frequency) be set to the
same value as the Fullscreen mode settings. If these settings are not the same, then any devices connected to the
media server's outputs (both Preview and Stage) will temporarily lose sync when switching between the Fullscreen
and Window modes or when the MBOX
Designer software is relaunched. With some display devices, the results of
losing sync, even temporarily, can be quite disruptive. With identical settings for the Mac desktop and MBOX
Fullscreen mode, there will be no loss of sync. (Desktop resolution can be set in the Mac’s Preferences window.)
