Bug: Screen blanks on monitor move

[Loren Pechtel]

Unfortunately I can't trigger this reliably.

My hardware configuration is 3 monitors. Monitors #1 and #2 are connected to the primary video card, an AGP card. Monitor #3 runs off a PCI card. They are physically arranged #2, #1, #3. If I launch Videolan on monitor #3 and then drag it to monitor #2 sometimes it blanks out on the transition from #1 to #2. Dragging it to #1 will restore the image and it will remain if dragged back to #2.

This is a Windows issue where as Microsoft describes in their Knowledge Data Base that an AGP card will take precedence over a PCI card and you may have problems when there are more than 2 monitors. Unfortunately they never describe the nature of the problems.

[Loren Pechtel]

But I'm moving from the PCI to the AGP--a Windows bug that gives priority to the AGP shouldn't cause a problem.


Incidently, it happened moving from #3 to #1.

Actually, I would think the problem would be the second monitor on the AGP card. But I have never had 3 monitors to try to work this one out. If it is workable considering Microsoft's statements.

I'm having the same problem. Any clues anyone?

1) It works *MOST* of the time. It always can be recovered by dragging it back and forth.

2) It very occasionally fails on PCI -> AGP primary.

Hmm! Now that sounds more like Microsoft.

Yeah, that's exactly how it works. My only problem is that I'm trying to build a software which moves the windows in place automatically, so dragging back and forth isn't really a possibility. I'm trying to solve it by moving the windows in like 10 steps to the target monitor withing the soft. This works on some videos, others doesn't. What I'm trying to achieve is that every window on my wall would work automatically, whatever the input video is.

If anyone can think of an easier way to achieve this, any help would be nice.

And btw. changing the VLC code directly from my part is not considered an option.
