I have delved into video conversion and signal processing in some detail for the QL, I have a few questions about the original signal:
What are the frames per second and number of lines in the image? What 'legal' signal is it most similar to? Is it possible to alter the frame rate, and/or to supply a pixel clock signal? 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.) I'm just trying to understand the problem and why the LCD monitor won't sync the nonstandard signal. If it's just one aspect of the signal it may be easily fixable and retain full screen display. If there are multiple elements to the problem, then not. Having access to the pixel clock and being able to manipulate the frame rate to 30 FPS - or even better 60FPS - would be extremely useful.
