WolfVision VZ-8 - Manual (Page 5)

The RGBHV- and DVI-output (#13 and #12) can output signals in the following formats:
- SXGA (1280x1024 pixel) at 60Hz
- XGA (1024x768 pixel) at 75Hz (default setting when resetting the resolution)
- XGA (1024x768 pixel) at 60Hz (default setting if auto resolution does not work)
- SVGA (800x600 pixel) at 75Hz
- SVGA (800x600 pixel) at 60Hz
Please note that the Visualizer can not check the possible resolution, if the connected units
or the cables* are not "Plug and Play" compatible. If the Visualizer can not detect the
resolution of ALL units connected, the outputs are set to the default of XGA (1024x768) at
60 Hz.
(*Cables with plug and play compatibility must have a 15-pin plug on both ends with all pins connected)
If you can not use the "Auto resolution" function, you can select the output mode manually
in the on-screen menu of the Visualizer (see page 9) or with the following key combinations:
For a lower mode simultaneously press both ZOOM keys on the camera head (#10)
together with the number 8 (arrow-down) key (#29) on the remote control. For a higher
mode press both ZOOM keys on the camera head (#10) together with the number 3 (arrow-
up) key (#29) on the remote control. In order to reset the output to the default setting (start
point) of XGA (1024x768) at 75Hz, press both ZOOM keys on the camera head (#10)
together with the number 5 key (middle of the number keys #31) on the remote control.
In order to achieve the best picture quality you must set the outputs of the Visualizer 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 compressed 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 Visualizer to a higher standard than the native resolution of your display unit!
If you output the Visualizer image on a CRT-monitor or CRT-projector, use an output mode
with 75Hz, 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 is the
best mode read the user manual of the connected units.
.
The default setting is that the "Auto resolution" function is activated. In this mode the
Visualizer constantly checks which units are connected to RGBHV- (#13) and DVI-output
(#12) and automatically sets the output to the mode that fits best for all connected units.
You can switch the Y/C (S-video) (#14) and Composite (#15) video outputs between the
video standards PAL and NTSC in the units on-screen menu (see page 9). Switching can
also be done by pressing
both ZOOM keys on the camera head (#10) together with the Preset
1 (for PAL) or Preset 2 (for NTSC) (#21) key on the remote control.
Please note that the picture quality of both video outputs is NOT AS GOOD as the picture
quality of the data outputs (#12 and #13). This is because of the limitations of the PAL/
NTSC video system and because of the fact that this is just a converted Progressive Scan
signal and not an original video signal. The picture quality of the Y/C (S-video) (#14) output
is still MUCH BETTER than the quality of the Composite (#15) video output. Please note
that images from the EXTERNAL INPUT (#11) are not output at the Y/C (S-video) and
Composite output!
