My laptop is Lenovo Y460, which is using switchable graphics (ATI and Intel).
The ATI part was burnt out few weeks ago. So I uninstalled and disabled the ATI graphics and I am now using Intel graphics only. But after that I can't use the HDMI output anymore. There is no response from the TV when I plug in the HDMI cable.
Does the ATI graphics need to be working with the HDMI function?
I guess Intel graphic cards also provide HDMI function?
