I am running an hp pavilion a1430n with an athlon x2 3800+ and an Nvidia 7300GT graphics card and Win 7 build 7100 installed. I have a tv connected as a secondary display. when i try to adjust the display settings for the tv, it will not apply the new settings. It attempts to apply but does not complete it. Does any one have any suggestions? It worked fine in xp and i don't understand why it is not working now!
