Philips 55PUT6400 Review - Sound and Verdict Review


Philips 55PUT6400 – Sound Quality

The 55PUT6400 certainly isn’t short of audio presence. As well as being able to reach strikingly loud volumes, it also puts out an impressively wide soundstage that stretches far beyond the confines of the TV’s bodywork. It also displays the ability to ebb and flow quite nicely to meet the demands of action scenes.

However, voices can sound a touch swallowed due to the lack of any forward-firing speakers. Plus, high details can sound a touch harsh at times due to a lack of convincing bass to counterpoint the trebles.

Other Things to Consider

If you’re thinking of gaming on the 55PUT6400, you should be aware that we measured its input lag – the time it takes to render its pictures – at around 50ms. This is a pretty average result that could result in the TV sometimes affecting your gaming performance. This is even more of a possibility as, in our tests, the 55PUT6400 sometimes registered measurements nearer 70ms.

Please note, too, that choosing the Game picture preset doesn’t automatically turn off all the TV’s lag-inducing processing. You’ll have to manually go through the options to try to get the input lag as low as possible.

Turning to the 55PUT6400’s Android TV implementation, following our experience with Sony’s KD-75X9405C, we were pleasantly surprised to find that the demands of the Android OS don’t seem to cause significant slow-down or bugginess in the 55PUT6400’s operation. However, some sort of “smart remote control” option to accompany the fairly bog-standard one the TV ships with would have been welcome.

Should I buy a Philips 55PUT6400?

If you’re looking for
respectable 4K picture quality in a large 55in screen, and your budget
won’t stretch beyond £850, the 55PUT6400 has plenty going for it. Just
bear in mind that you’ll need to put in a fair bit of leg work to get
the best from its pictures.

If you fancy an easier life, and slightly more natural images, and can live with a smaller 50in screen then the Panasonic 50CX700 is more attractive alternative.

Although it’s far from perfect, the Philips 55PUT6400 delivers more features and, with a bit of legwork, better picture 4K UHD picture quality than you’ve a right to expect for so little money.
