Looking at froogle, standalone scan converters start at about US$35 for one that can only do NTSC/PAL, and appears to jump to about US$280 for one that can do higher than NTSC/PAL resolution. Subtract a bit for the plastic box, connectors and wall-wart p/s. And yet a US$150 LCD panel presumably contains a scan converter, and one that does higher than NTSC/PAL resolution. Something doesn't add up. > OTOH, a QVGA LCD doesn't need an > interpolating scan converter to display VGA. How do you display 640x480 on 320x240? Perhaps the answer would be useful for TVs that don't actually resolve 720x480 (or the PAL/SECAM equivelent). > However, the bootstrap problem remains.

If the display supports the telling-the-graphics-chip-what-resolution-it-is feature, but does not support 640x480, would that work? Does pee-sea firmware insist on 640x480 regardless? Would the graphics chip convert? _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
