That won't work well. The only signals permanently available for PLL input are the QL sync signals and they are not stable enough to generate a decent pixel clock to feed TFT monitors. I'd use a separate time base for output, and decouple input and output via screen RAM. > It could for example also be used (with different parameters) to adapt a > Q40/Q60 videao signal Not the same hardware then. It would require faster RAM, more RAM, much better A/D and D/A conversion, and a more complex logic. > to standard SVGA (I still could not find a modern LCD monitor that could > properly display the 1024x512 screen of a Q60... I think you can give up that search :-( It only works with a modified video chip, and that only for a minority of monitors. All the best, Peter PS: Sorry for the poor quotations... I'm not subscribed to the list, have to copy & paste from the archive. _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
