CRT invalid display type ati radeon 9550

Probe varias actualizaciones del controlador hasta la mas actual al 1 de julio 2008, el problema continuo hasta que utilize el disco original de la tarjeta y solo instale el controlador; no use catalyst control center.

I tested many driver updates including the last from july 1, 2008. It worked for me to return to originally driver from cd not installing catalyst control center.
