Hello, I have a 2015 retina iMac that I'd like to convert to a 5k display (like Luke Miani:
). Since I have the iMac display already, it is less expensive to convert it to a 5k display than buying a 5k studio display. I have successfully opened up iMacs (pre-retina) before to do HDD / SSD swaps, so I am not afraid of doing this work myself. I know that pre-retina iMacs are different and more difficult, which is why I am trying to save time and frustration with this question.
I'd like to find the model number of the LCD display panel that I have in my iMac. I know it is made by LG, and it is an Ultra HD monitor, but in order to purchase a controller board, I need the LG model number. The model number is listed on the back of the panel (like ifixit: https://www.ifixit.com/Guide/How+to...r+To+Buy+The+Correct+Video+Driver+Board/40590).
But I'd like to use terminal to find the model before opening up the iMac (so that I can open up the iMac / display conversion only once - and install the correct controller board at that time - so that I can continue to use the iMac until it is time for the conversion - because the controller board is specific to the LCD panel - and opening up the 2015 iMac and resealing it is a big deal). The controller boards are typically shipped from China and can take weeks to arrive.
I've seen this command which I found from a 2010 post, but it doesn't work to display the model for the LCD panel in my iMac (understandably - the post is more than a decade old):
FAQ:
• I intend to re-use / re-sell / recycle the iMac internals that won't be used in the display conversion so they won't go to waste.
• I have experience opening up computers. I know retina iMacs are more complex to open that other computers or iMacs. I am ready for it.
• I don't want to spend $1,600 on a new 5k studio display when I have a perfectly good 5k display in my iMac (and I can spend under $300 to convert it).
• I know that I could buy a 4k display for much less than a 5k display, but I prefer to have the retina pixel density as I am protective of my eyes and vision.
• I know that the studio display has a couple of more features, but they aren't worth an extra $1,300 to me. I understand that your preference may be different.
• I know that I could buy a third party 5k display, but I don't want to spend $1,300 when on a new 5k display when I have a perfectly good 5k display in my iMac (and I can spend under $300 to convert it).
• The 2015 iMac is not capable of installing Ventura (not going the unsupported install route). I prefer to have a computer which is capable of the latest version of macOS. I will probably also keep my next computer until it is no longer capable of using the latest OS.
Thank you for posting if you have experience with ioreg, or another method of finding a LCD panel model number without cracking open the iMac.
