(--) NV(0): Virtual size is 1024x576 (pitch 1024)
That's just because I've set a mode "854x480/75Hz" but called it in the modeline "854x480". If you scroll a little bit further down (line 855) you can see that it is acceptet:
(**) NV(0): Mode "854x480": 45.9 MHz, 39.0 kHz, 75.0 Hz
(II) NV(0): Modeline "854x480" 45.86 854 896 1096 1176 480 482 494 520
I'd suggest talking to BenQ at this point, as either their documentation is erroneous, or possibly something is wrong with your projector. Perhaps they can provide you with a modeline for 480P.
I will do that. But something tells me, that they won't support any Linux stuff...
