34 VP-773 - The OSD Menu
BEST FIT – This setting re-sizes the video or
graphics input signal to “best fit” the output resolution
while maintaining the aspect ratio of the input signal.
For example, a composite video signal (4:3 aspect
ratio) will “best fit” to the top and bottom of a
widescreen output image, resulting in black pillars on
either side.
LETTERBOX – This setting compresses the top and
bottom edges of the input signal, but fills the width of
the screen. For example, to preserve a widescreen
film image on a 4:3 display.
6.7.2 Master Connection Settings
The Master Connection (HDMI1, HDMI2 or HDBT) is usually set to the main
output display so that the optimal resolution for that display can be obtained.
By setting the output resolution to Native, the VP-773 is triggered to read the EDID
of the main display and change the output resolution value according to the native
resolution of the display.
If HDMI/HDBT is selected as the Master Connection, and a new display is
connected to the Master Connection output (hot plug), the VP-773 automatically
reads the EDID of that display and updates the output resolution accordingly.
If it is not supported by the selected Master Connection, the system searches for the
best supported resolution. If the search fails (for example, if the master connection is
disconnected or EDID is unreadable), the resolution will default to XGA.
