iMac 2 gpu cards.Can I activate nvidia 9400 after pulling out HD 4670?
I found out my iMac 21.5 late 2009 apparently had 2 graphic cards in it. A dormant nvidia 9400 integrated graphics in the logic board and a removable Radeon HD 4670 (on a mxm card).
Having in mind I had to 2 Gpus I took out the Radeon HD 4670 for another computer in need of a graphics card, but now the iMac screen doesn't come up although I can hear everything working in the background.
Is there a way to activate the nvidia 9400 that is integrated in the logicboard? Even if I have to put the other gpu back in to set this up (then removed it - as to the first idea)?
Other iMacs run only with nvidia 9400 (the standard one). How can I ask the iMac to use this one as the default one instead?
Is this a good question?
