While the set is a 1080p panel as far as the output is concerned, the question I have after reviewing this http://www.av-sales.co.uk/SHARP-LC-52XD1E-130-.htm
is does it accept a 1080p/60 (or50) input signal and if so through which inputs. Note it states: Displays 1080i and 720p HD Signals
which indicates it won't accept a 1080p/60 signal.
Most sets that will accept 1080p/60 will do so only through the HDMI input. 1080i may be your limit and the PQ will not suffer watching film sourced video clips.
