Has anyone found a good calibration app for ATV4? Something to help calibrate the TV color and picture? I've used DVDs in the past for this but now that my setup is all HD it would be great to find a tool for performing this function.

I saw this one, no idea how good it is:

You can do some basic adjustments in Settings > Audio and Video > Calibrate

The only app I've tried is THX Tuneup. You actually download it for iOS device and airplay to the ATV, so it will work with pre-app-store ATVs too.

For a free option, you could also probably just find 1080p calibration slides (color bars and test patterns) as images on the Internet and add them to your photo gallery on the ATV.

To really do it right, you need a colorimeter and all that.

I found the AVS HD 709 test cards on YouTube which I've just tried on my TV and works great so just try using this for the basic settings for Brightness, Contrast, Colour, Sharpness & Overscan.
