Choosing and Setting Up an LED TV

Everything in this section is about decisions rather than mechanisms: what to buy, whether to replace what you have, and how to make the set you own look the way it should.

The buying guide is the place to start if you are shopping now. It works from the room outward, matching screen size, backlight type, dimming, brightness and gaming features to how you actually watch, rather than to a specification ranking. The upgrade page answers the adjacent question, which is whether a new set would be a visible gain or only a numerical one.

Once a television is in the room, picture settings matter more than most of the specifications that sold it. Showroom presets are built to win a shelf, not a living room, and the settings page walks through what to change and why. The burn-in page addresses the one risk people most often misattribute, and the Samsung page explains how one manufacturer's ladder of names maps onto real hardware differences.

If you read only one thing here before walking into a shop, make it this: decide your screen size from your seating distance first, then spend what is left on the backlight rather than on pixel count. Size is the cheap part of a television now and the part you notice every day; the number of dimming zones behind the panel is the expensive part and the one that decides whether a night scene looks like night. Resolution barely enters the argument at normal viewing distances, which is why 8K sets keep failing to justify themselves.

The second thing worth fixing on day one is the picture mode. Nearly every set leaves the factory in a “vivid” or “dynamic” preset designed to survive fluorescent shop lighting: blue-shifted white, crushed shadows, sharpening artefacts and motion smoothing all turned up. Switching to the Filmmaker, Cinema or Calibrated preset and setting backlight to suit your room costs nothing and is the single largest visible improvement most people can make to a television they already own.
