You need a cable from TB-2 to TB-4 (TB = Thunderbolt). If this cable is not available, then an adapter.
Hi, I have been using this setup with this cable to run a similar iMac as a second display for an iMac Pro. Unfortunately, this no longer works after upgrading to Monterey due to changes Apple made to the operating system. I think your M1 is running Monterey, so I doubt this will work with any cable.
Basically yes (same connection as MINI DisplayPort), but there is one combination where the cable does not work. Laptop (Thunderbolt) <-> Monitor (Thunderbolt) is ok Laptop (Mini DP) <-> Monitor (Mini DP) is ok Laptop (Mini DP) <-> Monitor (Thunderbolt) is ok Laptop (Thunderbolt) <-> Monitor (Mini DP) does NOT work
Both cables are Thunderbolt 2.
