Spare a thought for the Panasonic S30 that barely gets a mention from our forum members or, indeed, the manufacturers themselves, seemingly lost in the rush to sell 3D product. The S30 shares much of the same feature-set and processing as the G30, we looked at back in April 2011, but lacks THX Certification and full calibration controls in the user menus. The G30 was also fitted with a newer generation filter, to combat ambient light, but both are equipped with the new – for 2011 – ‘Real Black Drive’, 600Hz sub-field processing, a Freeview HD tuner and access to Panasonic’s, cloud based, Viera Connect platform.
At this stage in its lifecycle the Panasonic TX-P42S30B can be had online for around £450 so it’s certainly approaching the realms of a bargain basement option. Can the S30 cast off the shackles of disregard and put itself on the radar? Let’s see…
The ‘app store’ is complemented by the more usual BBC iPlayer, YouTube and AceTrax video on demand/streaming services and the almost ubiquitous Twitter and Facebook widgets. There’s a Skype application in there too although we couldn’t test if it was functional owing to the lack of proprietary camera/mic attachment. The S30 is also Wi-Fi ready but, again, we weren’t issued with the appropriate dongle to test performance although we’ve no reason to suspect it would be sub-standard.
The Panasonic TX-P42S30B isn’t able to connect to a home network for media file streaming but owners can playback content via USB storage and SD Card. Many will be pleased to see that .mkv container support is present via USB although, as ever, support will not be exhaustive. There’s also DivX HD and AVCHD file support for further HD video options and mp3, AAC and WMA compatibility for music playback. The S30 doesn’t show anything but .jpg photos but we can’t imagine that will trouble too many and there’s the basic slideshow and rotation features present.
Whilst it’s not the most feature packed TV we’ve seen this year, for this price-point we have no complaints and what is there works pretty well.
Measured Results Out of the BoxWith no THX mode or isfccc controls at our disposal we would have to hope that the Cinema or True Cinema picture modes would get us close enough to calibrate the greyscale in the service menu. True to form, the True Cinema mode gave us the best basis for our calibration, returning the following results for greyscale and gamma:
Moving on to colour reproduction, against the Rec.709 HD standard, and the S30 impressed giving us these results:
Calibrated ResultsSince we last had cause to enter a Panasonic service menu things have taken a slight turn for the better in that screen luminance isn’t altered dramatically, as it once was, and we were able to affect the White Balance controls without having to hop in and out too much. In actual fact the process is slightly less painful, in some ways, than using the user menu controls in the higher-end 2011 range but the controls are a little coarse and it took a few iterations before we were able to attain the following charts:
Picture ProcessingThe S30 showed all the strengths and weakness of its more illustrious siblings with some excellent scaling of standard definition and decent deinterlacing of video content that would, on rare occasion, trip up with some visible jaggedness. The S30 also stood up well when presented with a mixture of film based material with overlaid scrolling video encoded text and had no problems in displaying the full 0-255 video signal, when required. The fact that, with Clear Cinema enabled, the S30 managed successful lock on to NTSC 2:3 cadence yet failed to lock on (in time) with PAL 2:2 material came as no surprise as it mirrors what we’ve been seeing from Panasonic all year.
We’ve gone in to great lengths on the issues Panasonic plasma’s have had in displaying 50Hz content (in short, some will notice edge break-up under panning) and, to this end, Panasonic have attempted to alleviate the issue, somewhat, by introducing a Mid setting to their motion interpolating IFC system. We have to say we found it quite effective on video content, especially sports broadcasts, but it’s not something we’d want on all the time and the 24p Smooth Film setting is a crime against Blu-ray disc with some very unnatural looking movement, in either setting. The S30 is already to very competently handle 1080p24 material without need for a prop.
Gaming PerformanceWe had high expectations here and we weren’t disappointed by the snappy performance of the S30 when it came to gaming with the amongst the lowest input lag figures we’ve seen all year. In 10 tests, the S30 averaged lag of less than one frame, at 14 milliseconds, and we could sense no disconnection between controller and game. Some might have issue with low motion artefacting with games running at under 60fps, natively, manifesting in double imaging so we’d advise ardent gamers to take one for a test drive before purchasing as tolerances to this vary quite widely. The S30 also proved fairly resistant to image retention with any traces being washed away by normal content in short time. Those that like marathon gaming sessions would be advised to give their S30 a ‘break’ from time, much as they should do the same!
Energy ConsumptionPanasonic’s NeoPlasmas are designed to be energy efficient and this shows in the S30B consuming an averaged 120w, calibrated, and less than 1w when in Standby. They’re never going to compete with LED/LCD in this regard, however, and we just hope that they’re not further throttled by further regulations. Some hope.
Another complaint we’ve witnessed and read dozens (actually thousands) of posts on is the phenomena of ‘fluctuating brightness’, that manifests in scenes of mid to low brightness and causes the image to look like someone is raising and lowering the Contrast control before your eyes. Whilst we did see this occur on less than a handful of occasions we wouldn’t consider it anything likely to be spotted by the majority of owners and the behaviour of the S30, in this area, was actually quite a bit better than that of the G30 - although we’re guessing that’s not necessarily a range-wide difference, more a result of component variance, panel to panel.
When all’s said and done, the S30B punches above its weight in terms of picture quality and if the combatting of ambient light is not a concern, presents a viable alternative to the TX-P42G30; with the lights down, we would have been very hard pressed to tell them apart.
- Excellent black level and contrast performance
- Super fast gaming response
- Calibrated greyscale
- Very good out-of-the-box colour reproduction
- Attractive and responsive GUI
- All round video processing is good
- Full Viera Connect service
- 50Hz problems still evident
- Some fluctuating brightness apparent
- Still no effective 2:2 cadence detection
- Some might find styling too bland
Panasonic S30B (TX-P42S30B) Full HD Plasma TV Review
It wont be the prettiest TV on the shop-floor and its looks aren’t likely to win over your other halves but the S30 is no-frills and not likely to offend and nor does it have any distracting or unnecessary features to take you out of the on-screen action. The fact that it’s, more or less, an entry-level set does manifest in the lack of a 4th HDMI port and the dated mono-filter that doesn’t cope particularly well with high levels of ambient light or combat lighting from above. With the clocks just gone back, this is not something likely to be an issue for those with a day job!
The look of the menus is of the higher end sets, although lacking in calibration controls and a THX mode. Following a few logical replacements of key menu items, since last year, we find the menus easy to navigate and snappy in response; although the EPG is a continuing disappointment with its tasteless looks, advertising and lack of video/audio. Video processing was also of the same quality seen in the upper ranges, with some very decent scaling, deinterlacing and at least a stab at cadence detection. We expect Panasonic may well come fully to terms with the PAL 2:2 cadence by next year but, for now, it’s a ‘could do better’ on the report card.
The lack of calibration controls in the user menus meant we were forced in to the service menu to affect greyscale but it didn’t really hinder us unduly and we were able to gain excellent, believable tone and colour reproduction, despite the limited and rather coarse nature of the controls. Once we’d calibrated and freed the image of the green cast, the natural palette complimented the deep blacks in an extremely pleasing way and our only regret is that Panasonic didn’t send us the 50 inch for review. There are still some problems with break up under panning on 50Hz material and some fluctuating brightness is present but we’d wager most won’t notice either; and given the other qualities the S30B possesses, we find them forgivable. Every display we see has at least one issue that some will find unacceptable so, as ever, we’d advise getting out there to demo wherever possible.
The TX-P42S30B proved itself an extremely worthy performer when it came to gaming, averaging a measly 14 millisecond latency to controller input. Some may be put off by the ‘double imaging’ on games running at less than 60 frames per second but it never bothered us. The S30 isn’t going to save the planet but it does all it can by consuming just 120w, in calibrated state, and less than 1w in standby.
