Yes, another 84 inch 4K TV. It's impressive to be sure, but doesn't offer up anything the others don't.
The problem with brand new tech is that it's only brand new and impressive for so long. We've seen a pair of 84 inch 4K TVs already and though Toshiba's is almost certainly just as impressive, there's a bit of a dip in our excitement. After all, it's practically the same thing.
Toshiba's new set is unpriced at the moment, but since its a little more bare-bones than the others, we can expect a set that's a little bit cheaper. One of the nice things about the no frills approach though, is that the set is nice and sleek. No speakers means no extra padding.
