Panel detail
Panel detail	Panasonic's UK TX-P42G10B, TX-P46G10B and TX-P50G10B manual specifies native Full HD NeoPDP plasma panels.

Motion handling
Motion handling	HDTVTest identifies a 600 Hz sub-field drive for the NeoPDP panel; this is a drive technique, not the native frame refresh. It found good motion clarity with Intelligent Frame Creation off and no telecine judder from 1080p/24 HDMI input.	Intelligent Frame Creation and 24p Smooth Film are processing modes. AVForums observed artefacts with 50 Hz material on its review unit.

In the box
In the box	N2QAYB000428 remote, two R6 batteries, pedestal, cable clamper, mains lead, two ferrite cores, cleaning cloth, instructions and guarantee documents. HDTVTest said the UK model was available to buy by 15 April 2009, while What Hi-Fi? had reviewed it on 30 March; these sources do not establish the earliest on-sale month, so the release field uses year precision.	Pedestal and remote. Contemporary UK reviews conflict on the number of bundled 3D glasses, so no quantity is asserted.
