This `supported resolution 11' is not the same as the mode number to pass to
ps3videomode, it's a PS3AV_CMD_VIDEO_VID_* ID.

Vid 11 corresponds to PS3AV_CMD_VIDEO_VID_1080P_60Hz (i.e. 1080p).
While mode 11 is WXGA (i.e. 1280x768).

(Upon further inspection, this `vid' is immediately converted to a mode number,
 so I'll change the code to use mode numbers instead, and cause less
 confusion).

Looks reasonable for a 1680x1050 monitor...

Euh, `-f' shouldn't make any difference for modes 11-13, as they're always
fullscreen.

So your monitor advertises:

    Supported 60 Hz modes:   1080p 480p 720p 1080i (0000400d)
    Supported VESA modes:    VGA (00000001)

But 1080p and 1080i don't work. As 1080p is the best advertised mode, you don't
get anything to see :-(

Does this patch help? It should give you 720p by default.

Thanks a lot for your report!
