As the predefined modes in Picasso96Mode are extremely crappy, especially when used with the much more sensitive TFT monitors
Most LCD/OLED panels use standard timings, so I'm not sure why no one's created a standard set of predefined modes, e.g. VGA, SVGA, XGA, WXGA, et al, and distributed that. It would make a nice little attachment for the tutorial. At the very least, a small table could be included that lists the correct timings. If the timings are entered correctly, a decent analog LCD display at its native resolution should produce a crisp, digital-like picture with no adjustments required.
