I've been shopping for a new 4K tv and surround system. I've researched as much as I can myself, and most of it make sense, but I can't make sense of this. I'm looking at the Samsung 4K SUHD JS8500 120hz 55" hdmi 2.0 tv. I'm also looking at the Onkyo HT-S5800 5.1 hdmi 2.0 system. Here's where I'm confused. The Onkyo is advertised as "hdmi 2.0 60hz 4K compatible". Does this render the 120hz on the JS8500 useless? I looked at the 60hz JS7000, but heard the 120hz makes for a much better movie viewing experience. Does the tv translate the 60hz coming from the Onkyo to 120hz somehow? I just don't want to waste money on one piece of hardware when another piece of hardware limits what it can do. Please help me make sense of this! Thanks.
