If your TV is an older model and only has a RCA port then I would recommend trying an adapter.

Hello,
You would need to check the compatibility of the cpu you want to put in and the motherboard. Not all i5 and i7 CPUs use the same socket type. You need the model of i7 cpu you want to put in to check compatibility.
