So this 50" 4k vizio from Walmart says its 120hz. I want it. But I read somewhere on here that 4k TVs are 120hz at 1080 not 4k. And only 30hz at 4k. Is this true?

I don't know about this particular Vizio, but some other Vizio and Seiki 4K models are 30Hz at 4K and 120Hz at 1080

It emulates 120Hz I believe, and does 120Hz at 1080p. It uses HDMI 2.0 for 4K 60Hz.

If your device is not HDMI 2.0 (say an older Blu-ray player), it will be 4K 30Hz.

Also, you need content at 4K to even start.

So, so far, you can only use a computer to enjoy it. I am not sure NetFlix StartTV app of the TV will allow to playback 4K video (the few they are). I can't find any reviews.

That particular TV is true 120Hz which is pretty rare, most TVs use frame interpolation to "fake" >60Hz frequencies. But yes, the 120Hz will only work at 1080p, at 4K you will be limited to 60Hz (over HDMI 2.0) or 30Hz (HDMI 1.4a or below).
