Hi all, I have an iMac Intel 24" EMC 2267 and several months ago the video card ATI HD4850 die.
I replace the card with a Dell G92-751-B1 M17X/M15X Nvidia GTX 260M 1GB MXM 3.0 and it works fine but gamma is too high (it is like take a look to the sun without sunglasses). I tried to low it with same programs but I cannot lower to to an acceptable level (fn f1 and fn f2 keys dont work). I install windows 7 on bootcamp and cannot install any nvidia drivers, always computer tell me that cannot install the specific driver. In mac the System Information card model correctly listed (gtx 260m). Any idea?
