I have 2 24" Apple displays with AppleCare. Apple stopped the 24" displays when they revamped the iMac line to 27" models (the displays are the same panels that the iMac's use). I'm experiencing some burn-in and a few pixels are dead. If I were to have them replaced, are 24" panels/displays still in stock or would it be the 27" model (which I can't imagine Apple allowing)? Thanks!
