When such video streams are either encoded from HD frames or played back on HD displays in full-screen mode (either 720p or 1080p) they are scaled by non-integer scale factors. True nHD frames on the other hand have integer scale factors, for example the [[Nokia 808 PureView]] which has an nHD display.
