Supported App Resolution

The following table shows the supported app resolution for graphics and video.

Full HD Model (FHD)Ultra HD Model (UHD)
Graphics Display Resolution1280 x 720 HD (2K)1920 x 1080 FHD (2K)
Video Playback Resolution1920 x 1080 FHD (2K)3840 x 2160 UHD (4K)

For high-quality graphics display resolution on Ultra HD models, you should set the resolution of your app to 1920x1080. However, the Full HD models support graphics display resolution up to 1280x720. Therefore, for optimizing the display resolution for both Ultra HD models and Full HD models, we recommend that you submit two packages with different graphic resolutions of 1920x1080 and 1280x720 to the LG Seller Lounge.

The default setting of graphic display resolution is 1920x1080. To change the resolution to 1280x720, you should set the resolution property to 1280x720 in the appinfo.json file.

To get the app resolution (for graphics display) of a web app, use window.innerWidth andwindow.innerHeight properties. Or to find the video playback resolution, use screenWidth andscreenHeight properties of deviceInfo of webOS API in webOSTV.js library.
