Panasonic TX-L47DT50 Review - 2D Picture Quality Review


One of Panasonic’s most potent image processing systems is working away at the Panasonic TX-L47DT50’s heart, as is clearly evidenced by a claimed 1600Hz system. This is achieved through a combination of a 200Hz native panel, a scanning backlight, and sophisticated frame interpolation processing, and bodes very well for the TV’s sharpness and motion clarity.

The TX-L47DT50 is well equipped with picture setting aids, including colour management, gamma settings and plenty of options for all of its various processing elements. No surprise, then, to find the set endorsed by the Imaging Science Foundation (ISF) as a set capable of receiving a professional calibration from one of its engineers should you so desire.
Panasonic L47DT50
Inevitably we spent a good deal of our time while reviewing the Panasonic TX-L47DT50 engrossed in the Beeb’s HD coverage of the Olympics. And in these circumstances Panasonic’s set gave a very fine account of itself.

Dynamic colours
For starters, we were hugely impressed by the dynamism of the TX-L47DT50’s images. Colours are outstandingly punchy and vibrant, with rich saturations driven forcefully off the screen by its extremely high brightness output. It’s a really eye-catching combination, made all the more striking by the impressively extreme range of the colours on display.

Also extremely apparent while watching all the Olympics footage is the gorgeous clarity of the L47DT50’s images. Detail levels in the Beeb’s HD feeds are exemplary, with immaculate edges and pretty much endless subtlety when it comes to rendering such HD minutiae as the texture of the athletics track or the beads of sweat on the athlete’s faces.

Fast response panel
Even better, thanks to the Panasonic TX-L47DT50‘s excellent fast-response panel and powerful video processing, there’s hardly a trace of motion blur, even when the TV is first switched on (and so is running from cold).

You don’t even need to call in Panasonic’s motion processing systems to enjoy the excellent clarity the panel has to offer. Though if you do want to try out the Intelligent Frame Creation system on its lowest setting, you can do so (and enjoy a small reduction in judder) without the picture starting to look too processed.
Panasonic L47DT50
The generally high brightness levels of the Olympics footage also gives the impression at this stage that the Panasonic TX-L47DT50 is capable of producing a decent black level response. Certainly dark bits of predominantly bright images seem to enjoy a reasonably black tone.

The trouble with Harry
Aware that this appearance of good black levels might be an optical illusion caused by the extreme brightness and colour punch of the image, and with the black level problems of the L55DT50 still fresh in our minds, we tentatively fired up our current favourite contrast tester, the final Harry Potter movie on Blu-ray. And unfortunately Mr Potter and his friends caused the 47in model the same pretty much exactly the same problems witnessed on the 55in.

Basically, really dark scenes reveal that the L47DT50 actually isn’t capable of reproducing a really respectable black colour unless there’s practically no light in the scene at all, at which point the TV pretty much shuts its LED lights down altogether (meaning shadow detail takes a significant hit).
