This. In another comment I tried to equate it with a painting on a wall. A painting never fills the wall. The painting is whatever size and shape it is, and that's that.

Maybe the problem is a tv looks like a frame, and frames are made custom to fit the painting, and so any discrepency looks bad.

But now that tv's are both huge, and are featureless panels with little to no interesting frame let alone actual furniture quality cabinetry, maybe only now they can start to be seen as mini walls where it would actually be kind of pathological to require that every pixel always be lit just because they exist.
