You should really read the post before responding to it, I'm not looking for an adapter, I know the adapters exist, this iMac will refuse to accept input that is converted using those adapters, it ONLY accepts input from mini display port. However I do find hte mini-display port to vga adapter quite interesting because my store gets asked for them all the time but I have been advised by more senior employees that such an adapter does not exist without a super expensive converter box, I guess I'll have to make an inquiry about that.
