Comment 83 for bug 161893

Thanks for the tip, I retested with all TV output related options I found out the following:

These options must be used in order to enable TV output:

       Option "ForceTVOut" "TRUE"
        Option "ATOMTvOut" "TRUE"

This option prevents TV output working:

        Option "R4xxATOM" "TRUE"

And these options seems to have no effect (apart from setting PAL in use):
        Option "TVDACLoadDetect" "TRUE"
        Option "DefaultTVDACAdj" "TRUE"
        Option "TVStandard" "pal"

Output is still garbled but at least something is coming out again with tweaked configuration. Perhaps others who've had better output in the past can now enjoy working output already.

Thanks!
