I've bought a TV for the first time in ten years and see that many things have changed.

What's the purpose/reason/meaning behind the (ARC), (DVI) HDMI connections? I'm wondering which one I should hook up through my Blu-Ray and which one I should hook up to my cable box? I also have a third HDMI port that has no extra label.

ARC is audio return channel and may not work in all systems.

This TV isn't going to have anything special connected to it, just a Blu-Ray and cable box. I'm not going to hook my computer or a surround sound, or any game systems to it. That being said, is one better than the other for hooking up Blu-Rays or Cable boxes? Thanks!

Given what you have. No need to look at ARC.

It's only when we have those home theaters and receivers that we need to know about ARC, optical cables and such.

So in other words, all three inputs will work fine with the devices listed? Sorry, if I'm being dense.

For most of us? Yes.

I'm sure some will fret about this. I run out and plug it in.

ARC isn't an input (sigh)

This question is easily solved by a quick trip to google. Read up on the various types of connections first and foremost. (FWIW, DVI doesn't handle audio signals.) HDMI is the type of connection you should be using if possible for your Blu Ray & Cable box. ARC is a feature that may or may not be included in a piece of AV hardware, and it only works with an HDMI cable.
