Fujitsu P42HTA51ES 42in Plasma TV - Fujitsu P42HTA51ES 42in Plasma TV
Fujitsu generally has little truck with such TV ‘niceties’ as Scarts and built-in tuners, but the P42HTA51ES has both. Admittedly there are only two Scarts, and the tuner can only receive analogue broadcasts. But hey – any Scarts and tuner are better than no Scarts and tuner, right?
Other connections happily include the HDMI and component video inputs demanded by the AV industry’s HD Ready spec list, and there’s a D-Sub input for attaching a PC. More signs that this Fujitsu’s interest in normal TV duties is perhaps a bit reluctant, though, can be seen in the P42HTA51ES’s lack of any dedicated 4-pin S-Video or RCA composite video inputs – though you can at least get both these lower-quality signal types into the TV via the Scarts if you really need them.
Other key specifications of the P42HTA51ES include a respectable claimed contrast ratio of 3000:1, and a rather odd looking native resolution of 1024x1024i. This comes about from the TV’s use of Alternate Lighting of Surfaces technology, or AliS for short.
For a full explanation of how ALIS works check out our recent review of the Hitachi 42PD9700. But if you’re happy with a short answer, it would be that ALIS screens share their horizontal electrode strips (512 of them, in this case) between two phosphor lines rather than the customary method of using an electrode strip for each single line. The screen’s then alternate the electrode’s power between the two lines so fast that your eye can’t perceive the change and so is ‘fooled’ into seeing twice as many continuously lit lines as there are genuine electrode lines.
If the previous paragraph has left you bewildered, don’t worry; all you really need to know about ALIS is that it makes this Fujitsu’s native resolution high enough to qualify for the HD Ready logo.
As befits any self-respecting home-centric plasma TV these days, the P42HTA51ES sports a suite of processing systems designed to make its pictures better. Subsumed under the catch-all title of AVM II can be found MPEG noise reduction, mosquito noise reduction, and systems for making colours look more natural and contours less jagged.
