1.4.0.6 will not display unless "Fit to screen, no scrollbars" is slected.

Post by nvidia290 »

We upgraded to 1.4.0.6 and the only issue we have been having is when remoting into a PC if the person they are remoting into has two monitors the screen just turns black and is hidden.

The only solution I could find was to select fit to screen no scrollbars which kind of smushes everything together.

Also when opening from Quest the program defaults to fit to screen off which they can only get in by typing in the HN.

Is there any known fix for this? Where can I find the .ini settings so that I may turn this feature on, what would it be called? Is it SingleWindow=0 ?

Thank you

Hello, thank you for reply.

I changed the parameters as such, but no luck.

Whenever someone has two screens the Ultra VNC program is unclickable in anyway on the viewing machine. if I hover over the task bar where Ultra VNC is, I can see a preview of the two screens but when I click on it nothing comes up, it's like it's hidden or minimized. The only solution is to run it with fit to screen no scrolls bars selected.

Here is my configuration.ini file.

Do you see anything that may be causing this? Thank you so much for looking.

Your server config looks ok
Most systems are dual monitor server and viewer, i'm also using a dual screen without having this issue.

Current i don't have a clue why the viewer is acting like this

On the viewer you also have a lot of display options, try to ply with them.
See https://uvnc.com/docs/documentation-1-3 ... plays.html

You can also use an old viewer with the new server, it's backward compatible.
Using an old viewer you don't have the issue ?

Yeah it seems the issue is our techs have dual screen and if they remote into a single screen is fine. But when they remote into a PC that is dual screen this happens. What's worse is when we use quest to remote into to VNC even if we change the settings on the PC it will not open because it defaults to the non-fit screen setting so everyone has to use the Ultra VNC shortcut now.

Using the old viewer we had no issues.

Test were done with 2 and 3 monitors real monityor on the server pc.
Using the virtual driver we added some extra virtual monitors , max 9 was tested.

Just wondering, what does the switch monitor button do ( viewer site)
Does the vnc server tray indicate the ddengine is used for capturing ?

Check %appdata%UltraVNC viewer pc
It contain saved options for a specific server ( auto loaded) servername-port.vnc
Try to rename the one you are testing, restart viewer, you never know if it's something in the settings.

The viewer also has an option -position x y w h
vncviewer.exe -position 0 0 1280 800
