Windows Virtual PC Integrated Applications on Multi-Monitor systems

  • Comments 5

When using integrated applications with Windows Virtual PC on multi-monitor computers there are a couple of “gotchas” to be aware of.

We use Remote Desktop technology to provide our support for integrated applications.  And as discussed here Remote Desktop in integrated mode behaves like there is a single large display that is spanned across all of you monitors.

The guidance from the Remote Desktop team is that for multi-monitor setups:

  • All monitors should have the same resolution
  • The total resolution of all monitors should not exceed 4096 x 2048
  • The top-left monitor should be the primary display

Now, of my multi-systems – none of them have the same resolution, and one of them has a width of over 4096 pixels. So what I have learned is this:

  • You cannot move any integrated application above the top of your primary monitor
  • You cannot move any integrated application left of the left edge of your primary monitor
  • Things get really weird if you try to move an application right past 4096 pixels from the left edge of the primary monitor
  • If you do not have matching resolutions – it is best to not try maximizing an integrated application – as you will not be able to see it all

What I have done in both my multi-monitor computers is to set my primary display to my largest display / my display with the highest “top edge”.  This way I lose any monitors to the left of my primary monitor – but I do not get any weird clipping in the middle of a monitor (this can happen with other configurations).

  • I hear the artificial limitations of poor design choices.

    I can see why many teams make these - either lack of knowledge, lack of funding, lack of time.  One would assume that Microsoft teams either have or can find the knowledge and can find ways to resolve the other two problems.

    I'll grant that multi-monitor setups are not entirely common, and I ran into a few of my own issues a few years ago with a screen capture utility, but one would think this should already be well handled by all Microsoft teams by now.

    I'm not sure if I'm shocked or disappointed.  I suppose Raymond Chen would point out that MS programmers just programmers and prone to the all the same mistakes as other programmers, but with all the knowledge available on the campus and the resources available - it comes off as a pretty lame excuse for these types of problems.

  • In my experience, you should also avoid using (Shift)+(Windows)+(Arrow) to move an Integrated App around, even if you adhere to the multi-monitor restrictions.  The App will appear to move, but won't actually work on the other monitor.

  • Xepol -

    I am afraid to say that we have not figured out how to master time and bend it to our wills (we have an R&D project on this).  So, just like everyone else, we need to decide which issues will be addressed in each release, and which will be left for future releases.



  • Hire more people, you rich bastards!

  • Now that Remote Desktop has /Multimon support in Windows 7 (better than /span), will Windows Virtual PC be quick to pick it up?
