[mythtvnz] NVIDIA Dual Screen Limits

[Tortise]

Hi

I've not managed to get 1080i on a component HD CRT with simultaneous 1920x1080 on a 1080p LCD monitor, using an NVIDIA 8500GT.

It has finally(!) occurred to me that the card is not up to this, however the data does not seem to be readily available.  I've got 
1080i on the TV with 1280x960 (reduced from 1920x1080) on the LCD using two X sessions.

Matrox appropriately publish their data on the box.

Does anyone know what definitions the 8500GT and 9400GT are capable of driving two screens?

Kind regards
David
