Hi all and thanks for support, I have an Imac 2,93 24 inch early 2009 that will burn the graphics card (ati hd 4850) and buy a nvidia GTX 260M works well except that the brightness and contrast do not work properly , it's like looking at the sun directly and although I have managed to lower the minimum all the brightness and contrast still be properly and still much brightness and contrast. The function keys used to lower and raise the brightness not working , it may be that the graphic was a dell has a 30-pin connector that obviously can not connect to the iMac ?
Any ideas?
Thank you
