Dear User,
All TV Store applications have to support 1280×720 resolution. Other common TV resolutions (1920×1080, 960×540) are currently not supported. Although the TV Store browser itself supports regular scrolling, applications should be designed not to require scrolling, and if needed should provide their own custom mechanisms for displaying long lists of items or content.
