i had similar experience in using CRT TV as the 2nd screen, i got blank screen in 2nd panel.
Then, I tried different settings in ccc and dvbviewer and then the 2nd screen is alright. But I cannot remember the detail settings. Here are some hints:
1.Try to set both the refresh frequency of the panel to be 60HZ
2.Renderder setting: try "vmr9" or "overlay" |
