I have seen many threads on making your spare iMac into a slave monitor. I have found the solution.
All you need is an ethernet cord. Test this program out, or buy it for $30. I have it and it works beautiful. I run video across both screens without a hitch. If you are having trouble with latency, read the READ ME on how to get rid of it.
Enjoy.
