Forums -> UltraMon™ -> 3 monitors, only 2 can active, how to jump between them?
Saxtus   2011-07-27 08:25
I have a nVidia GTX 480.
It has 3 monitor outputs, but by design can only use 2 at a time.

I have monitor 1 as my main, but the thing is that I switch between output 2 & 3 many times per day, depending on what I do, as they have different sizes.

I've tried Ultramon's Display Profiles function, but don't it doesn't switches monitors, instead it switches resolutions of target monitors, with unpleasant effects.

Is there a way to make it understand that I need to turn off output 2 and turn on output 3 when I switch display profiles on Ultramon?

Thanks in advance.

On Windows 7 you'll be able to do this via UltraMon (requires version 3.1.0), on earlier versions of Windows you would need to do this via the software for the video card.

I have Windows 7 x64 and Ultramon v3.1.0 it seems that it have problems with the monitor switching.

Once the first switch takes place successfully, Ultramon scrambles the monitor numbers (as shown using "identify" function) so it messes up the other profiles.

Please post the system information from UltraMon menu > About, before and after you make the switch.

Might be a configuration issue, please send me the following to support@realtimesoft.com:

- CcdInfo log: to generate this, run CcdInfo.exe

- registry key HKEY_CURRENT_USER\Software\Realtime Soft\UltraMon Components: to save the key to a file, run regedit.exe, then right-click the key HKEY_CURRENT_USER\Software\Realtime Soft\UltraMon Components and select Export from the menu to save the key to a .reg file

Done.

I am having a very similar problem. It doesn't change the resolutions (all are 1080p displays) but it doesn't change which displays are enabled nor the monitor orientation either.

Can you share the solution with me as well?

Brian, please run CcdInfo.exe as described above and also send me the HKEY_CURRENT_USER\Software\Realtime Soft\UltraMon Components registry key.

I sent it via email.

Incidentally, I noticed that the numeric indicators change after applying settings that change which displays are active, closing the dialog, and reopening. It's always display 3 that is inactive. Not sure if that's relevant or not.
