Originally 72 Hz, 512 visible lines. > What 'legal' signal is it most similar to? At design time it was fine to use any legal resoltion of a multisync CRT monitor. The idea was to stay at the QL-style 2:1 ratio on 4:3 screen, epscially for the QL modes 4 and 8. Most flatscreens misunderstand the signal as 800x600, leading to bad interpolation. > Is it possible to alter the frame rate Yes I did that, as I wrote. > and/or to supply a pixel clock signal? Yes, but it is at the very maximum. Otherwise I would of course have increased it already. > This could open up the option of DVI conversion. (I have never > owned a QX0 and don't know if it uses a card or custom logic.) There is a slight chance to generate a pseudo FullHD signal, but only at unusually low frame rate. I keep looking at that, but it is difficult, logic was already optimized extremely to fit the chip. And not all monitors would accept it. > I'm just trying to understand the problem and why the LCD monitor won't > sync the nonstandard signal. Some do sync, but usually blur the picture by sampling 800 points on a 1024 horizontal line. > If it's just one aspect of the signal it may > be easily fixable and retain full screen display. Not easily fixable, I would have done so. Peter _______________________________________________ QL-Users Mailing List
