Hi Michel,
in one of my previous post on this bug report I wrote that changing TMDS
to CRT, as you suggested, wasn't working at all. This is why I never tried
again  in my latest tests. If I remember correctly, you described the
behaviour I noticed as "blooming".

I will check it once more today and will report it. If it does not work
than probably this is a bug that should be fixed, if it does work then we
may close the bug report.

Thanks,
Giuseppe
