This is a continuation of the thread "SSTV-625 Up Converter MkV (Five)...", I've changed the title to "SSTV-VGA Up-Converter MkI" for clarity...as it doesn't produce the old analogue TV standards, but 800x600 VGA which gets around the 50Hz/60Hz incompatibility problem. Though most modern TVs will handle both 50Hz and 60Hz, there'll come a time when those will be dropped from current production TVs with the closure of analogue TV broadcasting.
Even PC monitors in time will probably lose their analogue inputs...VGA, SVGA, XGA and so on...if not already...
