Regler les deux moniteurs en 1152x864

Bonjour,

Je suis sur mdv 2007 free, j'ai donc activé mon 2em moniteur en lissent attentivement la page de léa Multi-Head ou Utiliser plusieurs écrans et/ou cartes graphiques [www.lea-linux.org]
et sa fonctionne. Cependent l'ecran de droite n'ai pas de la même résolution que celui de gauche j'ai donc remplacé dans la Section "Device"
Option "MetaModes" "1152x864, 800x600; 1152x864, NULL" par
Option "MetaModes" "1152x864, 1152x864; 1152x864, NULL" mais l'ecran de droite se met en veille !

Comment faut il faire pour que met 2 écrans soit tout les deux de la même résolution 1152x864 ?

Merci d'avance, salutations.
