How To Convert An iMac Into An External Monitor

Cosa ti serve

    • Read and follow the iMac Intel 20" EMC 2105 and 2118 Display Replacement guide, and remove your screen completely.

    • Flip the screen over, placing it on a towel to keep it safe. Locate the manufacturer's sticker on the back of the screen, which should contain the screen's Model Number

    • The screen used in this particular iMac 20" A#### EMC#### is an LG-brand model-LM201W01, though yours may be different.

    • Search either AliExpress.com or Ebay.com using the search phrase “Your-Screen-Model-Number Control Board”.

    • If your iMac is a 20", they should be around $30-$40. If 24", $60-$80.

    • Order the video driver board for your screen. It will probably ship from Asia, and take 2-3 weeks to get to you.

    • It probably will not come with a power supply. This is normal. Most video control boards require 12v 5A power supplies. You may have one in your spare electronics bin, so check there before buying one: Old routers, PC laptops, etc may have compatible power supplies.

As my 2009 24” iMac just died (third, and maybe final, drive failure), I am very eager to see this completed.

Can you comment on the differences between available video control boards/ inverters?

It’s over a year since Paul K (above) asked if this page could be completed. I’d also be keen to see it. Any chance?

Hi, will this page be completed? I would love to mod my 2011 iMac

I have news. I normally use my old iMac as an external monitor with my macbook pro, connecting it via the firewire port and adapter.

I had to use the SwitchResX app to get a decent screen size and experienced only very sluggish performance.

Today i discovered that you can get far better results with native macOs stuff. Doing:

System Settings -> Displays -> Show resolutions as list -> Show all resolutions

works like a charm, with a lag that is very acceptable. I have no idea when this feature showed up.

It has been a long wait, but thank you apple.

Can you do this with a Mac (27-inch, Late 2012)?
