Better YouTube streaming on your smart TV
Smart YouTube TV is a free and open-source application that was created by an independent developer named Yuriy Lyskov. This multimedia app lets users install and use a customized YouTube client on their smart TVs that run on the Android TV operating system and those that support side-loading an APK file onto them.
Smart YouTube TV functions similarly to the standard YouTube application that runs on various mobile devices. The main difference is that the former has been optimized to provide a better experience for streaming videos on larger-screened smart TVs that operate on Android TV or various set-top boxes. Smart YouTube TV will help you follow your favorite topics online.
How do I use Smart YouTube TV?
Before installing Smart YouTube TV, go to your system settings, look for security settings, then enable the "Install apps from unknown sources" option to allow you to install an app from external sources. Then, transfer your downloaded APK file to any external USB flash drive, plug it on to your smart TV, and install it like you would any mobile app on your smartphone.
When you first open the app, you can choose from four devices/resolutions options: 1080 Main, 1080 Alt, 4K Main, and 4K Alt. Choose the one that works for you, and you can tick the "remember" checkbox to apply it the next time you open the app. It also allows you to log in to your YouTube account without the need for Google Services.
Additionally, Smart YouTube TV supports remote controllers, is fully localized, and doesn't need root permission to work. Just some things to take note of, though. For one, it's not officially supported by YouTube or Google. Another is that it's not actively maintained anymore. You can still try it out with your specific TV model and still use all of its features, though.
A good YouTube client for smart TVs
Overall, Smart YouTube TV is a good YouTube client that was made to work better with larger screens and smart TVs. It supports up to 4K resolution, does not rely on Google Services, and works with your remote control. While it's no longer being actively developed, if your TV is still compatible, it works quite well and is worth checking out.
