Displays different patterns so you can quickly adjust or check your TV's brightness, contrast, colors or overscan.
The application does not make any settings, it is up to you to make the settings on your TV.
This app should be used on Android TV devices or Android based TV boxes. It's useless on a phone unless you're using Chromecast or something like that.
Set the brightness to minimum and increase until you can see the differences in black.
Set the contrast to maximum and lower until you can see the shades of white.
Depending on the quality of the screen, some shades 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 phase of the wiring.
Only for 5.1 installations. The device must be Dolby Digital AC3 compatible.
This application is a personal project on my free time, be kind :)
