Not very interesting, as it is a multiple of 640x400...

See https://github.com/CHiPs44/hagl_pico_vgaboard/blob/develop/include/pico-vgaboard-modes-1280x800.h.

Interesting, in fact, as it makes 640x400, 320x200 & al. modes available in 60Hz instead of 70Hz.

Perhaps having an "halved" 1280x800@60 could be an acceptable compromise?

83.46 MHz => rounded: 83.5 * 3 = 250.5 MHz for sysclk, OK for vcocalc.
