What's more, for this latest version of AVM, Fujitsu has reworked the internal algorithms to enhance the video-mode detection that is particularly important for HD broadcasts. It now also has pixel-by-pixel processing and detection, and four-frame referencing to cope with the complex calculations demanded by HD signals. The new AVM engine claims to process standard-definition signals up to four times faster than most rivals, delivering improvements with that, too.
With HD footage, the Fujitsu's picture is outstanding, as a number of different traits join forces to make images look almost overwhelmingly natural and involving.

The first of these concerns colour - more specifically, the exceptional subtlety with which the screen portrays even the finest, most infinitesimal difference in shade. This helps pictures look realistic and solid, ensuring there's little sign of the 'striping' effect still seen with many plasmas.
The AVM II system is presumably responsible for its outstanding suppression of fizzing noise artefacts over horizontal motion. Moving objects look very smooth, too.
The sheer enormity of the 63-inch screen highlights another of this Fujitsu's image strengths: a fine detail delivery that exceeds expectations (the P63XHA51AS has a 1366x768 resolution, which on paper fares poorly against the 'Full HD' 1920x1080 of some competitors). The clarity and sharpness of a high-quality HD source is a sight to behold, reminding us of just what a difference HD can make to a truly big-screen viewing experience when the screen is up to the job.
There is considerable finesse in dark areas as even the subtlest of shadow details and greyscale shifts is shown with utter precision and delicacy. It does no harm that the black level gets much deeper and enjoys a more natural tone than previous generations of super-screens from the brand.
Another aspect where the P63XHA51AS improves substantially over previous Fujitsu giants - as well as some of the company's current smaller models - is with its colour fidelity. This is because high-definition signals enjoy eminently natural shades free of any over-ripeness even during dark scenes. Out of the box, we measured colour temperature at 10000K but after calibration we got a more manageable 7800K.
One or two colour issues occasionally creep in when you step down to standard definition, though, with reds in particular appearing a little bit orange. Also, SD images reveal faint traces of motion-noise so notable by its absence with high-definition. Otherwise, the pictures hold their own surprisingly well - at least via a digital source such as a DVD player or digital TV receiver.
Not everyone will be looking for a monitor of this size, but there's no doubting the drama and majesty of this screen. Without doubt, Fujitsu's P63XHA51AS is a startling example of plasma technology.
