I have been unable to connect my laptop to my 50 inch plasma TV. The laptop detects it as "PANASONIC TV" and I am able to change resolution of it etc, however, the TV still remains without any signal.
I have tried updating the drivers and it still does not work. I suspect it may have something to do with not having the key combination to switch to my TV. As the HDMI port appears to be a part of the NVIDIA 425M, the usual key combination of fn + f8 does not work as I think it is tries to switch monitors on the Intel GMA instead (only shows LCD screen) though I am not sure.
I have tried the rigorous display detection inside the Nvidia Control Panel to try and force the display but it is still blank.
This works with my sister's laptop and with my PS3 but for some reason, not my laptop.
