Show Secondary Display only

[Gregguz]

I use multiple displays and would like to show second monitor only (not a main display)
primary=0
secondary=1

Tried different versions 1.2x, 1.3x, 1.4, on various Windows 10 versions: (1809, and 22H2)

Always got two monitors at the connection, need to use switch button to get monitor 2 only.

It works when you select 'Show Primary Display' and deselect 'Show Secondary Display' - monitor 1 only,
but not other way round.

Please help,
Thanks
Greg

Thanks Rudi for a quick reply, I haven't got an email that my post was approved.

primary=0
secondary=1

Yes, I have got this two lines in the ultravnc.ini file (on the server side)
on the client side there's no this file as I have got only Viewer installed.

Please help.

You need to tell the server what his default "sharing" screen is.
Then the viewer start using this. There is no viewer option.
