What television settings do to the picture

Pulenaz: find the setting behind the strange picture

A film looks oddly like a live studio recording on Pulenaz’s television. She replays the same shot of a person walking across a room, first with the motion setting high and then with it off. The first pass looks unusually smooth to her; the second has a more familiar film-like movement, though the pan is less smooth. She keeps the second setting for the film.

She makes one change at a time and returns to the same shot, instead of switching several controls and guessing which one mattered. The choice is personal: when she tries a fast sports clip, she prefers some smoothing and leaves a little on for that kind of viewing.

A picture mode is a group of settings. Pulenaz compares two modes using a close-up of a face: one makes the face look very bright and intensely coloured; the other is softer and warmer. She starts with the second, then adjusts its colour separately rather than trying to fix everything with brightness.

iJustine: notice what each control changes

iJustine uses the same street scene to compare a few controls. Turning up the backlight makes the whole image easier to see in a bright room; it does not add a new detail to the scene. She lowers it again for an evening viewing, when the brighter setting feels harsh.

For sharpness, she looks at the edge of a sign. At a high setting the border has a conspicuous bright outline; lowering it makes that outline less noticeable. For colour temperature, she uses a white wall: the cooler setting looks bluer, while the warmer one looks more yellow. She leaves the viewer with a choice to make by eye, not a number to copy.

LG’s webOS picture guide describes backlight as a screen-brightness control, colour temperature as a cold-to-warm adjustment and TruMotion as a set of options for moving pictures. It also says available settings can vary by model and input.

Use a scene you know

For a dark scene, Pulenaz lowers the black-level control on her television and the coat disappears into the shadowed wall; raising it brings the coat back, but too high makes the wall look grey. She settles between those extremes. In a bright cloud, she raises contrast until the pale detail merges into a white patch, then lowers it until the cloud’s texture returns. Unlike the screen-light control she used for the room, these adjustments change how the darkest and brightest parts of this picture are rendered. She notes the starting values so she can return to them.

The rest of the menu can help with the viewing experience too. In a dialogue scene she tries a speech-focused sound setting, then switches it back to compare voices with background music. She also turns captions on for that scene and off again afterwards. Those choices change what she hears or reads, while the picture controls change what she sees.
