## Description

Default picture settings of TVs and projectors often make them look great on the sales floor but at the same time they show a distorted version of what the film director had in mind. Proper screen calibration can restore the image but it also requires calibration equipment and software. Fortunately basic calibration can be performed with simple test patterns and the human eye. This app provides such test patterns and a short description how to use each one.
