When your car screen is ultra-wide or ultra-tall, the native YouTube app typically maintains the video’s original aspect ratio (e.g., 16:9). As a result, black bars may appear on the sides or top and bottom, preventing the video from fully utilizing the screen — which can impact your viewing experience.
Recommended Solution: Use SmartTube Next (Third-Party YouTube Client)
SmartTube Next supports custom zoom settings that allow videos to scale properly to your screen size.
Setup Steps (for ultra-wide / ultra-tall screens)
1. Download and Install SmartTube Next
- Search for SmartTube Next on APKPure,
- Or visit the official website via Google Chrome:
https://smarttubenext.com - Download and install the APK file
- Open the app after installation
2. Play any YouTube video
3. Tap the HQ icon in the bottom-left corner of the video
4. In the menu that appears, select:
Video zoom—Fit either width or height
5. The video will now automatically scale to fit your screen proportionally—providing a true full-screen experience even on ultra-wide or ultra-tall displays.
