One of differences between display and TV is that [overscan](https://en.wikipedia.org/wiki/Overscan) is typically applied to TVs. TVs in overscan mode hide a 5% margin of a picture and show the rest in full screen. Generally, TV app developers should be careful that UI could work properly whether a TV would be in overscan mode or not. (It is unnecessary for displays, though.) For example, pictures could be displayed in the full range of 1920x1080, but active UIs should be placed on the action-safe area (the inner area surrounded by the 5% margin). IMHO, including "TV" in the UA string could help web apps to control UIs by JavaScript in this manner. Note: Android TV has the similar guidelines. https://developer.android.com/design/tv/style.html -- GitHub Notification of comment by tomoyukilabs Please view or discuss this issue at https://github.com/w3c/presentation-api/issues/303#issuecomment-227327173 using your GitHub account
