6 Part Number: M785-0203-115 Updated: 3 October 2008
modified layout before moving on to the next one. Alternatively, set your system’s date and time configuration to a
different time zone (click the K-Alto, Quad, or Quad-Dual button, point to Settings, and then click Date/Time).
Internal clock
Issue: When using the unit’s internal clock as the time reference for clock components, there could be a variation
of up to 10 seconds over a 24-hour period.
Workaround: Use an external LTC reference input, or synchronize the internal clock to an external NTP source.
MWO-SDM (Mezzanine) output permits illegal video black levels
Limitation: The MWO-SDM mezzanine outputs graphics and video from the Kaleido-Alto/Quad/Quad-Dual as an
HD video signal. If any of the graphics from the Kaleido-Alto/Quad/Quad-Dual use black values below RGB 16,
16, 16, or if the “Expand Video Dynamic Range” option has been applied in KEdit, the MWO-SDM allows these
illegal values to pass through its video output.
Workaround:
If you are using the output of the MWO-SDM, do not enable the “Expand Video Dynamic Range” option in
KEdit. Make sure that graphic elements don’t use RGB values below 16 (i.e. for black, use RGB 16,16,16, not 0,0,0).
Full screen setting lost after reboot
Issue: If a Kaleido-Alto/Quad/Quad-Dual view is set to full screen and then rebooted, the display view will return
to the view setting that existed prior to the full screen view. The same occurs following a change in resolution.
Video calibration
Issue: For SDI inputs configured to de-interlace in the temporal mode, the sharpness control is not active.
Issue: For 1080p 23.98Hz and 1080p 29.97Hz inputs, the Duration, Occurrence, and Detection Window
calibration parameters specified for Black/Freeze/Luma error detection are ignored.
Audio threshold precision
Issue: Audio threshold precision is +/- 1 dB.
Updating from previous version
Issue: When updating your Kaleido-Alto/Quad/Quad-Dual it may happen that the task bar becomes red and
displays an error message.
Workaround: Press the Reboot button located at the right end of the task bar to restart the system.
