iMac G4 as a DVI monitor

A few years ago I found an old iMac G4. It’s now over ten years old and these days PowerPC chips are not too useful. However it did have a very nice 20″ 1680×1050 IPS display in an attractive case.

If only I could connect this display to some other computer! I decided to try to hook it up to the Mac Pro I recently purchased from Atlassian.

I bit of web searching found the incredibly helpful dremeljunkie.com. I discovered that internally the iMac does use the same TMDS signalling as a DVI connector.

That means in theory I just have to hook everything up the right way and it will work! :)
