Set up and calibrate your Apple TV
1. Adjust the picture
Setting up an Apple TV is self-explanatory, so you only have to intervene manually if problems arise. Set the format in the settings under “Video and Audio” (for example “4K HDR” for a compatible television set, in Europe with 50 Hz). If you switch on “Fit to content” for the dynamic range and the frame rate, Apple TV is not based on the television, but on the video being played. If you suspect that image areas are cut off on your device, scroll down and click on “Zoom and Overscan”. Apple TV will now show you a frame. You can use the menu on your TV set to adjust the image section so that the mark for “full screen” can just be seen.
Die App TV Tune Up (1.09 euros, all download links in the web code) will help you with further test boards, among other things for contrast and sharpness, and explanations in English when configuring other parameters.
2. White balance using the iPhone
With the help of an iPhone with Face ID, the box automatically adjusts the color balance on your television. For this you need at least tvOS 14.5. The white balance only changes the signal of the Apple TV, but not the settings of the television or the signals from other sources (TV tuner or DVD player). Therefore, if necessary, adjust the color settings of your TV set first. If you made changes later, you would otherwise have to run the automatic calibration for the Apple TV again.
