So I have two iMac 27" from 2015 and 2017 that features the 5K panel. The computers both work perfectly but they are somewhat limited to older operating systems, if not using open core legacy patcher (sigh, I wish Apple wasn't so driven by enforcing e waste.)

As there are some controller boards made to modify these machines to instead work as monitors, or both as monitors for other computers and the internal one I am also curious about this! Apples 27" Studio display is about 2000 dollars, each and adds nothing I need honestly. And as I already have the screens the boards for around 200 dollar each makes for a quite cool investment. Im going to try to de laminate the screens from the glass as one glass unfortunately shattered but I do see this as a good thing as I really would prefer a much smaller frame around there screen anyway.

So, my question now is, which board should I pick? As they have been around for some years there's been a few updates and there seem to be several different producers of similar but different boards. Early ones, and some still, require if using DisplayPort that two cables be used whereas some that are newer higher version of dp protocol itself (1.4 I believe) requires just one. Not sure about HDMI support for 5K but that would also be good as I plan to use these screens for many different things.

For me USB-C is not necessarily most important as I prefer screens that does NOT try to power the computer. Don't get me wrong, that is great for some users but having three screens on my desk usually means that I already have something that will power the computer. I have also noticed that my different thunderbolt docks have been going crazy warm when used with my old 5k ultrafine screen. That screen is now sold though due to some issues with the color around the edges in the end.

Anyway, I am sure some of you have done these mods and have clever insights and ideas to share. Im curious and happy to read what you might have done!

I am using studio speakers and already have a tracking webcam so I have no need for a silly studio display or XDR display more than my laptop as its XDR is at least 120 hz and awesome enough in that sense :).
 
There is plenty to read about 😃

You cannot use the original logic board, as this has to be removed.

Removing iMac screen panel broken glass is really (really) difficult.

The Chinese do it on an industrial scale, but without the equipment it is really messy.

However it probably is possible, although the metal frame of the screen isn’t designed to be looked at without the glass covering.

Wow that was a great and surprisingly detailed thread I have to say. Silly me not finding it first.

Will try to study it in detail tonight!

I can imagine it is really difficult to remove the glass, and it is a really stupid reason it is broken too. I guess many before me have done the same stupid misstake of not taping the screen at least temporarily with something before startint to use it. As I had just replaced the dead SSD with a new one I had issues with bluetooth so I connected a usb-keyboard, and seconds later the entire screen fell out.

Crazy enough the connectors and everything was fully working and didnt come loose or anything. Just the glass that shattered thankfully into just lines and not loose sandy/sharp bits.

Honestly it doesn't even bother me for how I use that screen but of course it would be nice to remove it and perhaps even fit an anti glare cover instead and pretend its nano texture :).
As difficult is my middle name, it also is a task for me :)

I am between jobs and these things are the things that keeps me alive. Depression is one hell of a drug.
