Can I control TV power from the AV side?

Hi. I am wondering if the device can have TV control from the AV side. Thanks.

I don’t think it can. You are looking for an extender that supports two-way IR control? Check this out.

Thanks. This should work.

Do I need to buy the IR extension cable myself?

Yes, you get one from the package. Visit amazon and buy another pair you can go two-way then.
