Moxi HD DVRs support 480i, 480p, 720p, 1080i, and 1080p 24 and 30 Hz TV resolutions. Automatic resolution switching passes through the native resolution of source programming, which helps to preserve picture quality. Moxi products also support down-conversion to standard definition. Cross-conversion between HD signals (720p and 1080i) are very good. However, up-conversion from SD to HD introduces significant video artifacts, and 480p output produces a very soft picture. It is recommended that 480p not be used, and that any up-conversions are done by the display hardware rather than the Moxi.
