I have bought two ATI Radeon 4350 HD graphics cards and they both work well seperately. But only the first one will output most of the time. If I go to System -> Appearance -> Monitors it will only detect the monitor on the first graphics card.

I have check using hardinfo and the system has definitely detecting both of the graphics cards so I don't know why it isn't detecting the monitor.

I am running Maverick 64 bit
