The Dark Side of Demo Mode: Why Your New TV Looks Terrible at Home The joy of buying a new television is short lived for many consumers who discover that their purchase doesn't live up to its touted picture quality.
Instead, it's plagued by brightness issues, poor contrast, and an aesthetic more akin to a Times Square billboard than a cinematic experience. Store mode, also known as demo mode, is the culprit behind this problem.
Manufacturers enable this setting on new TVs to showcase their products in retail environments under harsh fluorescent lighting with maximum brightness and contrast settings that are far from ideal for home viewing.
