Old HDMI for 4k
I got my home back about 2 years ago and the previous home owner had already wired the theater (it was never set up). I am in the process of setting up the theater and had a question on wiring. The HDMI was already wired long ago and I want to know if there is some adapter or something I can put on it so that it will be able to run 4K content if needed. The AV guy who set it up said there is some adapter that can be added and was talking about active vs passive, but I have no real idea what he meant.
