Resolução 1600x900 monitor samsung b2030 Nvidia 9600

[r0t3ch]

Estou há um mês pesquisando e não consigo a minha solução.
Ganhei um monitor Samsung b2030,e não consigo usar a resolução nativa de 1600x900.
Meu Ubuntu é o 10.10 uso uma placa Nvdivia 9600.
o Driver Nvidia está instalado
Nvidia x server instalado (não tem a resolução)
acredito que o problema seja porque o monitor está ligado na saída DVI como um adaptador vga para o monitor e um adaptador s-video/rca para  a tv

A minha placa apesar de ser 9600gt ela é reconhecida como 9800gt mesmo no windows



Só para constar a meu vídeo onboard é uma gf8100 e reconhece a resolução e o monitor perfeitamente

Já tentei a gambiarra de usar este xorg na 9600 mas também não funcionou.
