ENABLE_UPDATE. Sometimes there is not enough bandwidth (especially with high-resolution
RGB sources), following error message will be sent back from the V
ISU
PLUS
:
Syntax:
VISU ERROR VISU <VisuNr>: Insufficient transfer bandwidth
<AmountOfValues> <WinNr> … <WinNr>
Arguments:
Arguments Description
<AmountOfValues> amount of following values
<WinNr> a window number, which has bandwidth problems

arguments of TRY_ENABLE_PUDATE command
The first thing to do to solve those problems is reducing the processing frame rate (see
HW_SET_PARAM) and retry. Only reduce it to halve the frame rate (Value = 1) when video is
used! You can go further when using RGB. When this is not enough you can always start to force
downscaling of sources (see WIN_SET_PARAM).
