How many pixels are in a standard 4K TV screen?

8,294,400 pixels. A standard 4K UHD screen has a resolution of 3,840 by 2,160, which multiplies out to 8,294,400 pixels — almost exactly four times the roughly 2.07 million pixels of 1080p "Full HD." The "4K" name refers loosely to the horizontal pixel count being near 4,000, not to any multiple of the number four. Multiply the dimensions. The resolution is 3,840 by 2,160, and multiplying gives the answer directly. Any pixel-count question is a multiplication, and the only thing worth remembering is one of the two dimensions — the other follows from the standard sixteen-by-nine aspect ratio. The naming is the trap, and the explanation names it. "4K" refers loosely to the horizontal count being near four thousand, not to four times anything — though confusingly it does happen to be four times the pixel count of the previous standard, because doubling both dimensions quadruples the area. Two different reasons for the same number, only one of which is the actual etymology. That area relationship is worth internalising for any resolution comparison: doubling linear resolution quadruples pixels, and therefore roughly quadruples the data. It is why each display generation demands far more bandwidth and processing than the name suggests, and why the jump from one standard to the next is always bigger than it sounds.
