This guide is an evolution of an answer which I posted to Can I Mod an early 2009 24" iMac to external monitor?: The question "Can I mod my older iMac to use it as a monitor?" has been asked on iFixit and many other internet forums for over a decade, and it is rarely answered correctly.

This guide is a serious hardware mod. This is not target display mode. This is not a software fix. When this guide is followed, the user will be able to string a video cable between another computer and the iMac and have the iMac behave just like an external monitor.

In summary:

1) Completely teardown the iMac, removing everything.

2) Install a video control board, new inverter, and new power supply for the screen.

3) install new video-in ports on the exterior case.

4) Re-install the screen, reassemble the iMac case.

so that the case is empty.

    • 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 or 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?
