Thanks Matthew, the StarTech does the job perfectly, with an excellent, crisp picture. Not your fault, but regrettably on my AOC monitor a message comes up saying "Monitor does not support this signal" or something like. AOC helpline say "That is a problem caused by too high frequency out from your AV out.
as max frequency supported by this monitor is 80KHz/75Hz ,Max
resolution
is 1280*1024/85Hz"
StarTech haven't replied to my enquiry yet.
So I'm done for with this one, unless someone knows a work around?
