iMac Target Display (Late 2015 Model/4K Retina Display ) - Win-10 Laptop extend monitor

Hi,

I'm trying to extend my office win-10 laptop display to iMac. Tried Type-C to Thunderbolt-2 Converter from Apple for this purpose and followed steps ( Command-F2 & Command-Fn-F2) mentioned on the Apple support page. Unfortunately, this is not working.

I'm a bit penchant for the iMac display and a fan of apple's retina 4K display; so don't want to replace it with other external monitors for my work from home setup.

I'm not sure whether the Late 2015 Model supports Target Display Mode or not (it's not clear from apple's support page),

Or some other changes are required to get this working. (Any workarounds)

Your expert advice is welcome to get this sorted.

Thanks,

....yes it is, except for mistakes made during the recent revision:

No 24-inch iMac every supported TDM.

FWIW, an Early 2009 24" iMac did come with a Mini Display Port so it should be able to be used as an external monitor.

You're welcome. I'm not sure it supports TDM 100%. I do know there are at least a few YouTube posts that seem to indicate you can attach an iMac with a Mini Display Port, even to an M1 Mac. No Command F2 needed. There were at least two posts here by users saying they successfully did so.

Sorry that is incorrect, the ONLY iMacs that will work with PCs are 27" late 2009 and 2010 iMacs. Those are the ONLY ONLY ones that will work, early 2009 24" iMac will not work. Neither will the 20" or 21.5" versions of 2009 and 2010 iMacs.
