I’m still angry that they deprecated target display mode. For a company that talks so much about recycling it’s really messed up they don’t support it. Such an amazing way to give life to old but incredible monitors - you’d have to spend $1000+ to get anything remotely resembling the quality of that display. You can’t even use ones that previously supported it on current Mac’s.

You can't continue to support Target Display mode when the connectors and cables of the day don't yet support 5k displays.

If you have an older 5k iMac, there is an inexpensive third party hardware kit to convert it into a display with modern connectors.

There are countless non-5k iMacs. I never said it had to be that. I had a beautiful 27” 2.5k display from 2011 I could’ve put to work.

There is no excuse other than laziness IMO. They likely decided not enough people use it and that they didn’t need to keep an excellent feature (total speculation to be fair). I can use iMovie to directly control/run playback from a dvcam from 2002 via like 4 daisy chained cables - including FireWire 400 - but they can’t connect an iMac anymore over thunderbolt 4 after supporting that for over a decade? Nah. Maybe there is a legitimate reason but I am incredibly skeptical.

The iMacs before the 5k version did support Target Display mode.

They dropped it when the cable and connector standards of the day didn't support a display that big.

That's not laziness, it's a technical limitation.

Now that we have newer high bandwidth connection standards, you can once again use a newer iMac as an external display over a thunderbolt connection.

Yes the previous iMacs sent a signal. Their current computers don’t receive the signal. This is not about the 5K display, you’re missing the core problem. It stopped working when the silicon line came out. You can’t get any iMac to work in target display mode on silicon Macs.

That’s not a technical limitation, that’s laziness. Go read more about this. It simply doesn’t work anymore without 3rd party solutions.

There is literally nothing stopping you from using a modern iMac as an external display using a thunderbolt connection today.

If you're OK with video compression artifacts, you can even do it over a WiFi connection.

You cannot grab an iMac, plug it into a silicon Mac, and get a picture on the iMac (without 3rd party software). This is incorrect. Please go look this up. The feature stopped working when silicon Mac’s came out. It only works on Intel Macs. 5K iMac or not.

Absolutely. The display on the iMac 5K was amazing. Ended up giving that machine to a nephew of mine when I moved to Apple Silicon but Apple really dropped the ball here.

If you have a 27" iMac with the Retina display then you can get a kit to transform it into a monitor.

The strangest thing is that with Thunderbolt 4+ you could easily do this in software only I suppose?

There are third party apps like Luna Display that do this now.
