Hi, I have a 2011 27" iMac that I need to replace the LCD. Is there some way to use either a 2010 or a 2009 display. I found some information about using a 2009 in a 2010 iMac by changing the control board mounted on the display because the connector were changed. But, I can't find any information about the 2011 display. The 2011 is very hard to find. Thanks so very much!
