Hey everyone i just purchased an AMD radeon 7770 1GD5 V2, i installed it into my computer but now my extended monitor doesnt ready. The monitor i am using right now is attached to the MB and my extended to the graphics card. i installed drivers and stuff but the catalyst tells me i downloaded everything but there were warnings. i cannot see the warnings but it said everything was installed successfully. my PSU is running 550W so power isnt the problem. i uninstalled everything and reinstalled but still doesn't work. can someone help me please!!!! i spent countless amount of hours already :'(
