OS: macOS Sierra 10.12.6
Node: 8.1.2
Yarn: 1.7.0

Watchman: Not Found
Xcode: Xcode 9.2 Build version 9C40b

Description

I've been following #16500 and finally had a chance to try it out. I built a pretty barebones app following these instructions and deployed to both an Apple TV and a Fire TV Stick. Below you can see photos of how my app looks on both devices.

Steps to Reproduce

Follow the instructions in #16500 and the React Native docs. Build and deploy to Apple TV and Fire TV Stick.

Expected Behavior

Both devices, when running at the same resolution (1080p @ 60Hz) should display the same.

Actual Behavior

On the Apple TV, everything looks perfect, but on the Fire TV Stick it looks like everything is super zoomed in and squished.

Apple TV:

Android TV / Fire TV:

Side Note: I followed the instructions from the docs and found one thing missing that was required for Amazon's Appstore to allow me to select a Fire TV as a target device. The following line needs to be added to your AndroidManifest.xml:

    <uses-feature android:name="android.hardware.touchscreen" android:required="false" />

You can find the relevant instructions in Amazon's documentation.

I've discovered, per the Fire TV docs here and here that the "Display Resolution" is 960x540. I have confirmed this on my device by looking at Dimensions.get('window').

I'm not exactly sure how the React Native core project should handle this.

My question, however, is as an app developer, how do I go about handling this inconsistency?

I was having this "issue". But I found out that it's because Apple tvOS as a pixel density of 2 and Amazon fire has a pixel density of 1.

Meaning your font sizes will be double the size on Amazon fire
