Hello list,
I have a problem with my GEM configuration (WinXP). I am working at a laptop with a second monitor connected to the VGA output. Windows uses this monitor to extend the Windows desktop.
When I move the GEM window to this secondary monitor, it doesn't render anymore. Instead I see a black window or the last content of the window, and - when moving the window around - remainders of the window (like no working refresh cycles).
Could this be a problem of GEM (hopefully something to be configured) or should I rather assume a problem with my graphics card here?
Thanks for any info Urs
Hi,
just a guess, that the 2nd VGA output has bad or no real openGL/3D support. Or some graphics memory issue? Often with less dedicated Hardware, the 2nd Desktop has less graphics calcualting power assigned...though there might be some experts around.
good luck,
Peter

I think most (non apple) laptops only have hardware acceleration one monitor(not both simultaneously). One some laptops, you can asign your VGA output as the main, and the laptop monitor as the secondary. You will then only be able to render on the VGA output. For multi-monitor support, it is best to go with desktops, as laptops are made for business people (unless, once more, you pay extra and buy a mac).

Hi Thomas and Peter,
thank you for your ideas. I was afraid of this kind of info. I'll have to look into the laptop's documentation to get out of this. Unfortunately I _need_ to use the laptop in the performance - no way of bringing and setting up a desktop there...
Best Urs
