Hi,
I had an issue with my mac starting which I resolved by replacing the graphics card. The mac now starts without issue BUT!
In display preferences there is only one display resolution, no detect display button and if I try to calibrate the sliders have no effect
I have tried resetting PRAM and SMC with no effect and also tried a different monitor

This is a brand new Graphics card (delivered today)
*NOTE* also tried DVI and VGA cable
Does it look like the new card has issues or perhaps a firmware issue?
