You can connect a high-quality home theater receiver or other surround sound decoder devices between your VAIO computer and a TV using an HDMI connection.
You can adjust the screen resolution of the connected TV with your VAIO computer. See Changing the Resolution (Size) of the Screen Image on an HDMI-Connected Device for more information.
With the HDMI connection, the volume can be adjusted by the connected audio device only. Your VAIO computer has no control over the output volume of any connected devices.
