When I comment the ConnectedMonitor line my CRT works fine and there is nothing on the TV. In the log file I then see XFree only detects my CRT and therefore disables TwinView. I need that line. When I use only the TV alone it works. It MUST be possible to enable both TV and CRT at the same time.
All GF4 have TV-out. Someboby must know what might help. I'm sure its just a detail of a problem by I can't solve it. That's why I posted here. I keep my fingers crossed and hope help will turn up.
