Hello! I recently bought a new iMac and am having issues with the screen. I heard they use 2 manufacturers and wondered how I can tell if my current screen is a Samsung or LG? I also have a 2010 Macbook Pro and found that it's a Samsung screen (which has worked perfectly since purchase!) using the Terminal.app - but this doesn't seem to work on the iMac. The iMac screen is going to be replaced, would it be unreasonable to ask for the replacement screen to be Samsung? Any help or ideas would be really appreciated! Thanks!
