UVNC fresh rate

Post by Zwakele »

is there a way to set the refresh rate for uvnc, I have a PC that needs to be refreshed like every 5 seconds for the security guard to view the access doors at my workplace.
now you can only view for 5 seconds and you see no changes after that

So... I hope you're more lucky than me :)

Sorry Prisma, I didn't see your previous post.

I've had great luck with these server settings and the Viewer set to Medium connection speed.
PollForeground=1
PollFullScreen=0
PollUnderCursor=1
EnableHook=1

Not yet but it did fix the dual monitor issue and this persons issue: https://forum.ultravnc.net/viewtopic.php?f=50&t=28832
These settings will be in the next release however as they really seem to make a difference.

Hi,

bad news. My experience is that the settings above are very fast and possibly they're good for working fullscreen. But the background isn't refreshed properly. Yes of course, the settings say PollForeground=1, PollFullScreen=0. But that the result is that bad I didn't thought... :(
