>Subject: [PATCH] drm/radeon/kms: only enable underscan by default if the monitor supports audio
>
>Users with TVs or monitors that don't overscan by default would prefer
>to not have underscan enabled, while users with overscanning TVs prefer
>underscan.  This should hopefully make everyone happy as most monitors
>with audio tend to be TVs which overscan by default and monitors without
>audio don't overscan.  Underscan can still be overriden by changing the
>connector attribute.
