Help required for dual screen and multitabling

[Luckyspikes]

Hello,

first,sorry for my poor english, i'll try to do my best.

I've got a problem when i'm playing 8 tables on party network : i'am using 2 19" lcd screens (1280 * 1024) and when i "tiles" tables, they are all reduced on my main screen.

Is it possible to auto tile tables on 2 screens (4 and 4) ?

i've got a 7800 geforce, drivers up to date.
Must i activate a specific option on my graphic drivers ?

Thanks for your help
