Resolution and refresh rate
55 Version 1.5
In order to achieve the best picture quality you must set the outputs
of the SCB-12 to match the native resolution of your display unit
(e.g. LCD or DLP projector or monitor).
Important: What matters is the native resolution of the projector or
monitor, not the maximum resolution that it can display (in com-
pressed mode). The native resolution is the actual number of pixels
of the built-in LCD display or DLP chip of a projector or monitor.
Most LCD or DLP projectors can also display higher resolutions
than their native resolution, but only in compressed mode and with
inferior picture quality.
Do NOT set the output of the SCB-12 to a higher standard than the
native resolution of your display unit!
If you output the SCB-12 image on a CRT monitor or CRT projec-
tor, use an output mode with 75 or 85Hz, because 60Hz may show
a slight image flickering. For LCD/DLP projectors or monitors and
video conferencing units 60Hz is the best choice. If you are unsure
what the best mode is, read the user manual of the connected
units.
Do not set a higher refresh rate than your monitor or projector can
display, otherwise the monitor or projector can be damaged!
Follow the instructions in the user manual of the connected units.
For optimum color reproduction set the display device to sRGB
standard.
With none-RGBs display devices may it is necessary to change the
gamma setting in the on-screen menu see page 29ff.
For correctly streamed images, the RGB/DVI output has to be set
to the same image format (4:3 or widescreen) as the multicast
streaming format (see page 45).
In case the connected display is not capable to show an image with
the selected resolution or refresh rate, change the setting with
following shortcuts:
Change resolution/refresh rate upwards:
press simultaneously both FOCUS keys on the unit (#23) and the
Number 2 key (up-arrow, #18) on the remote control.
Set resolution/refresh rate to AUTO:
press simultaneously both FOCUS keys on the unit (#23) and the
Number 5 key (help, #25) on the remote control.
Change resolution/refresh rate downwards:
press simultaneously both FOCUS keys on the unit (#23) and the
Number 8 key (down-arrow, #18) on the remote control.
If no remote control is available, connect another display or change
the resolution/refresh rate by sending command codes via RS-232
(or USB, Ethernet/LAN).
