Hi again, I had one more idea. If we restrict the conversion to TFT monitors, this might provide significant cost/size reduction.
The QL provides a 50 Hz vertical repetition rate, and for TFT this frequency might be okay. The converter might be able to work without buffering the whole screen content then. Maybe only 10% to 20% are enough if the design is done in a clever way. In this case, the internal RAM of a small FPGA is sufficient. The slowest VESA mode without interlacing seems to be 60 Hz, but I tested my normal TFT with 1024x768 @ 50 Hz and it worked fine. It would be interesting to find out if 50 Hz works with all TFT VGA monitors. Anyone who can switch his/her graphics card to 50 Hz non-interlaced? :-) All the best Peter _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
