To use HDMI audio with some displays that have a native resolution higher than 1920x1080, you
must set the display to a lower HD resolution.


Some HDMI displays have a native resolution that exceeds the maximum supported HD
mode. For example, displays with a native resolution of 1920x1200 exceed the maximum
supported HD mode of 1920x1080.


Applying this native mode results in display overscan which cannot be resized using the
NVIDIA Control Panel since the mode is not an HD mode.


To avoid this situation and provide a better user experience, the driver treats certain TVs–
such as the Viewsonic VX2835wm and the Westinghouse LVM- 37w3–as a DVI monitor
when applying the native mode. Because the driver does not treat the TV as an HDMI in
this case, the HDMI audio is not used.
