Hello, i have been trying to solve this problem for about 2 weeks now and im completly out of ideas.
For the past 2 years i have had this custom hand built desktop, AMD motherboard and processor, radeon hd 5700 series graphics card, etc.
Also for the past 2 years, i have had a non-stop dual monitor display with my lcd monitor and my led tv. I have never had a problem, it has always been plug and play, both with 1080 resolution, and i never had a problem.
About 4 months ago my hard drive crashed and i had to format a new hard drive. I dont remember what software i had, but for some reason i cant get my dual monitor setup to work anymore. My lcd monitor works perfectly fine, it is recognized as a monitor and gets 1920x1080 resolution, but when i plug in the tv, it has 640x480 resolution and the option to change it is greyed out and it is only recognized as a "generic non-pnp monitor"
I have tried updating all my drivers, un-installing every driver i could find, unplugging my monitor and using only the tv, installing the amd catalyst control center, and i have no idea what to do now...
Can anyone please help...
tl/dr: Dual monitor setup no longer works after a reformat, drivers updated, reinstalled, cata control center didnt help either. I have windows 7 64 bit amd proc with radeon hd 5700
