Composite video TV out problem with Sapphire Radeon 4870

    Just installed this card and with both the initial version of Catalyst and
    the latest version (9.10).

    Unfortunately there's no cloning option of the main display onto the TV, the
    only option is to drag the 'disabled TV monitor' icon to the "Main" box,
    this brings up a "swap devices" option. Clicking on this results in TV out
    (with no TV overlay/Theatre mode) but the main monitor is blank.

    I tried switching the main VGA monitor to 1024x768 and lower, with various
    refresh rates, the result was the same.

    When the TV monitor is shown in the "Attached displays currently disabled"
    box, right-clicking on it gives no options at all.

    expecting after years of use of the Radeon 9500. With that, the TV output
    provided a 'windowed' section of the desktop and full screen in Theatre

    I'm hoping someone can tell me where I'm going wrong...

    Would I be better off trying an older version of Catalyst and if so, which

    Resolved by using the second DVI port for the main VGA monitor, a shame this
    info isn't shown in the context menu...
