That's a TV feature where the LEDs are positioned behind the panel
and grouped into a number of tiles whose lighting can be controlled
independently.  I can't find hard figures on the number of tiles,
but we're talking dozens, maybe a few hundred--compared to millions
of pixels.

I'm not aware of a computer monitor using local dimming, but I
haven't been paying particular attention to that area.
