If you employ Philips’ Perfect Natural Motion processor you can remove all the judder and blur from pictures. This system doesn’t work quite as effectively on the 47PFL6907 as it does on those higher end Philips TVs that use the brand’s flagship Perfect Pixel HD processing engine, but it’s still worth experimenting with on some sources – especially broadcast ones – even if you’re probably best only using it on its lowest power setting.
Personally we wouldn’t use the Natural Motion system while watching HD films, especially in 3D, as with this sort of content you’re much more likely to notice motion processing glitches like flickering and lag.
Despite the backlight clouds at the top, meanwhile, the 47PFL6907 actually delivers a pretty competent contrast performance, producing deep blacks without removing too much brightness from the image. Shadow detailing isn’t bad either where the backlight clouds aren’t in the way – a situation helped by the screen’s surprisingly strong ability at soaking up reflections from your room.
Colours are vibrant and punchy, but also enjoy plenty of finesse and a good range of tones. There’s not quite such a high-end feel to colour reproduction as you get with the PFL7007T series, but overall colours still look terrific for the 47PFL6907T’s price.
The 47PFL6907T is also great fun to watch in 3D. Its use of passive technology means you don’t have to worry about flickering if you’re watching in a bright room, or the sort of crosstalk ghosting noise common with active 3D technology.
There’s also practically no loss of brightness or colour vibrancy in 3D mode, compared with the quite heavy hit both these picture aspects can take with some active 3D systems. Finally in the plus column, the sense of depth in the 47PFL6907T’s pictures feels natural and the whole viewing experience feels much less tiring.
The reasonably large 47in screen on the 47PFL6907T does also reveal passive 3D’s weaknesses of ‘striping’ over the edges of small or contoured objects; a small reduction in detail levels; and the occasional bit of visible horizontal line structure.
The biggest problem, though, is the way the backlight clouds at the top of the picture described earlier appear to ‘lie across the top’ of dark 3D scenes, disrupting the 3D effect. This will likely infuriate picture enthusiasts.
Nonethelss, for a typical family environment, the 47PFL6907T’s practical 3D appeal and its quality with bright, colourful material is undeniable.
Up next on our check list is standard definition. The 47PFL6907T does well here in two respects, as its powerful processing makes SD sources look sharper and more detailed while also retaining more colour punch and credibility than you see with some TV upscaling engines. The only issue is that standard def images on the 47PFL6907T can look a little noisy unless you use the noise reduction tools. Yet these tools can make the picture look rather soft.
Overall, though, the 47PFL6907T is a perfectly solid standard def upscaler for those thankfully now rare moments where you can’t watch HD.
The 47PFL6907T sadly has one last picture weakness to reveal before we’re done, though. For running our usual input lag test records a seriously high figure of more than 130ms, even when using the TV’s Game/Computer modes. High input lag figures are disappointingly common with TVs built around LG’s passive 3D technology, but the figure recorded on the 47PFL6907T is the highest we’ve seen in 2012, and makes it a seriously compromised option for gaming on.
We’re able to wrap up on a more positive note with the 47PFL6907T’s audio, which is excellent for such a slim TV. A woofer on the set’s rear helps it produce a much wider, more powerful mid-range in which the set can handle vocals, treble details and even a modicum of bass without sounding cramped or harsh.
The soundstage isn’t the widest, perhaps, but it’s certainly cohesive and engaging, allowing you to be immersed in the action much more effectively than the audio performances of most skinny TVs.
The 47PFL6907T is Philips’ first and hopefully only stumble with its current TV range. To be fair, much of the usual Philips quality is there for large chunks of your viewing time, and the TV looks gorgeous so long as you don’t expect it to live up to Philips’ ‘frameless’ claims.
But the severity of the backlight bleed plus the lag issues film and gaming fans will regularly be faced with on the 47PFL6907T means we’d recommend that Philips fans instead step down to the PFL6007 series or, preferably, up to the PFL7007T range instead.
