Displays different patterns so you can quickly adjust or check your TV's brightness, contrast, colors or overscan.
The application does not make any adjustments, it is up to you to make the settings on your TV. It is also not an application for professional use.

This app should be used on Android TV devices or Android based TV boxes. It's of no use on a phone unless you're using Chromecast or another similar device, but that's not the recommended use.
Also not suitable for HDR signals

For a first configuration:
- choose the black bars model, set the brightness to minimum and increase until you can distinguish the differences in black.
- choose the white bars model, set the contrast to maximum and lower it until you can distinguish shades of white.

Depending on the quality of the screen, some nuances may not be visible.

The application also allows you to test a home cinema installation. You can check the speaker assignment as well as the wiring phase.
Only for 5.1 installations. The device must be Dolby Digital AC3 compatible.
The application also has a simple sinusoidal signal generator.

This app is a personal project in my free time, please be kind :)
