yes dude i am using the dvi thx that explains that then lol,,,another question,,,when i go to display propertiesits showing 2 moniters
1,plug and play monitor on nvidia ge force 7800gt
2,viewsonic vx2025w series on nvidia ge force 7800gt

the plug and play 1 will go to a res of 2048x1536 while the viewsonic will only go to 1600x1024,,,now if i set it to the viewsonic 1 shut down the display properties box and reopen it it sets its self back to the plug and play monitor,,,now im only have 1 monitor plugged in although i run 2 graffix cards in sli mode
