TCL 55-inch 4k Smart TV

Is this the same model?

I’m considering upgrading my 1080p Vizio for this as a computer monitor, but at the same time I’m considering waiting a while longer for a refurb HDR 4K TV.

Amazon reviews are unfavorable on the update cycle on the apps, and on the quality of the sound, FYI.

I bought this for 428 new at a major retailer and that is their regular price not a sale and not refurb.

Soooo, under the “Features” area it says that the tv is 120Hz but under the “Specs” it says the tv is 60Hz. So which is it?
