Comment 2 Marc-Andre Lureau 2013-05-02 13:13:48 UTC

the windows agent doesn't support sparse monitor config, see bug 953973

However, I think this bug should try to fix the fact that the display becomes black instead of showing the enabled monitors.

Comment 3 Marc-Andre Lureau 2013-05-03 12:00:49 UTC

Bill, can you verify that the 4 monitors are available in the guest "screen resolutions" dialog?

It seems the default ram=64M vram=64M fails to load one of the 4 devices. I am not sure where the bug belongs. But in this case, we can't manage failing monitors.

Comment 4 Marc-Andre Lureau 2013-05-03 12:02:53 UTC

Once bug 953973 is fixed, and 4 devices are correctly set up, it seem to fix that bug.

granted vel ack and moving to ON_QA for verification as the result of the 953973 fix.
