The separate question of what might be the theoretical resolution of the tv-out - hooked up to a non-standard monitor is also an interesting one.

The relevant part of the schematic is on the left of page 2.
The tv out pin of the SoC is connected to a 3u3H inductor, and a 47pF cap to the Vfb pin.
This then goes to an analog switch at the top of page 8 - and straight to the output of the socket (through an ESD filter).


The DAC itself IIRC has a stupid maximum clock - 40MHz.
I would need to chec what the inductor/cap mean.

(however - you couldn't connect a _standard_ monitor of any description here, and get 1024*768).
At best it would be mono. Even if it's possible at all.

Another theroretically possible option would be USB-host with a USB video card - this is very much under development - nobodies gotten USB working properly yet.
