depuis que g chagé de carte graphique (mystiqye g200 pour une radeon ve), mon ecran ne supporte que une fréquence de 60 hz.
C'est un sony 17" multiscan210 es qui supporte des frq jusqu'à 85 hz. Si j'augment la frq de la carte grahique, l'ecran devient flou.
Je croie qu'il y a un pb entre la carte mere et la carte graphique.
y-at-il une solution?  
carte mere asus p5ab; radeon ve, amd k6-3 500mhz; 384 mo de ram

pour faire remonter mon pb
