Switching the displays from LCD to TV (AV) with Fn+F7 at my PCG-GRT 815M doesn't work anymore. I can hear the sound on the TV but I can see no picture. There is also no icon (LCD / TV / LCD & TV) anymore.
What can I do?
If you have connectet your Laptop to the PC you can try to change the settings.
Right click on the desktop in the opening Menu select propertys.
In the now opening Windows you select Settings. Than click on Advanced. On the next window select GeForce FX Go5600 than click on the left side of the window on nView and select cloneing. Now you can see the Desktop on your TV.
Then I can see only the desktop-wallpaper on ther TV.
