Panasonic W85 vs LG OLED B6

Unfortunately, we do not have good news here. The Panasonic W85B is rather dim – its peak brightness does not exceed 300 nits, so it’s hard to talk about any true HDR effect. In practice, this means that scenes which can “shine” and make an impression on other screens simply look like ordinary SDR with a slight boost in colours here. Our measurements and film tests confirmed this – regardless of the content, the W85B will not extract anything more from HDR. Therefore, if someone is looking for a television specifically for HDR, it is better to look towards other models. As consolation, the fact remains that in terms of colours, the W85B performs quite well. It is a QLED television, so its colour gamut coverage is wide, and most films and series look natural, without a distinct “washed-out” effect. The colours are saturated, so in everyday viewing, there is no sense that something is strongly amiss.

The LG B6 is a moderately bright OLED. After calibration it reaches around 800 nits, roughly 200 nits more than last year’s B5. That’s down to the new, budget OLED SE panel from LG Display. In practice it simply gives a bit more headroom and makes HDR look fuller in many scenes than on last year’s lower‑end OLEDs. That does not mean the B6 has no limitations. In very bright shots, when a large part of the screen is strongly lit, brightness can fall below 400 nits. This behaviour is typical for OLED TVs, especially in this segment, and that’s where you see the biggest difference compared with more expensive models. Even so, we judge the B6’s results as genuinely solid. It’s still not a TV for breaking brightness records, but the HDR effect is strong enough that films truly feel like a step up from ordinary SDR. Colour gamut Using the OLED SE panel has had a slight impact on wide colour gamut coverage. Compared with last year’s model the results have fallen by a few percentage points. It covers roughly 96% of DCI‑P3 and about 71% of BT.2020. That doesn’t mean the colours on the LG B6 are weak. In most films and series they look lively, well saturated and simply pleasing to the eye. You only notice the difference in very bright, highly colourful scenes. Then colours lose some intensity compared with QD‑OLED panels. This stems from the WOLED panel structure. Besides red, green and blue subpixels it also uses a white subpixel, which helps to boost brightness. However, this comes at a price. At very high luminance some colour is effectively 'diluted' by the white light, so the saturation of certain colours can be slightly lower. In everyday use this isn’t a major issue, but in the most demanding scenes you can notice it.

When testing the Panasonic W85B, we obviously started with Filmmaker mode, as this is today’s gold standard when it comes to watching content “as the director intended.” The problem is that this television is quite far from those intentions. The biggest issue turned out to be an excess of red – both in SDR and HDR. The image often appeared too warm because of this, and in some scenes, it was almost “blazing.” Additionally, there is the issue of brightness management. When we looked at the gamma or EOTF charts, it was clear as day that in most scenes, the television brightens the image more than it should. The effect was simply predictable. Details can get lost, there is flattening, and highlights are blown out across the entire screen. We know, of course, how to correct this, but it must be said honestly that it requires a lot of work during calibration. Out of the box, the W85B does not provide a picture close to reference – it is rather a television that will always interpret colours and brightness a little “in its own way” without professional adjustments. Unfortunately, this is to the viewer’s detriment.

We tested the LG B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes produce very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is, in any case, a much better starting point than Vivid or Eco mode, where the picture is heavily boosted and noticeably less natural. On SDR material the factory settings perform really well. Colour errors are small, the gamma response is correct, and the picture during normal viewing looks natural and does not feel overly "pumped up". It's a bit worse with HDR. When such content is played you quickly see that the white balance hasn't been set perfectly. Too much blue and red gives the image a slightly pink tint. This is also confirmed by colour gamut measurements and the ColorChecker, where samples clearly shift in that direction. It's not a flaw that completely spoils the picture, but it is noticeable with HDR films. Therefore anyone who wants the most faithful image should consider calibration, which we cover further on in the review.

Fortunately, calibration made a significant difference for the Panasonic W85B, particularly in SDR content. Here, the improvement was really noticeable – we managed to balance the whites and somewhat tame the tendency of the television to excessively brighten the entire image. The picture became more coherent, and the colours gained a naturalness that was lacking in the factory settings. Admittedly, the results from the Color Checker are not perfect, as the W85B has visible issues with green saturation, but overall, we evaluate the post-calibration effect in SDR very positively. The situation is a bit different with HDR. Here too, we managed to reduce the tendency to warm up the entire scene, so the image performed significantly better than in the factory settings. However, the same issue we mentioned earlier is still evident – the television interprets the image too much "on its own" and brightens the entire screen. The lack of local dimming only exacerbates this effect. In summary, briefly in SDR content, the W85B performs really well after calibration and is more than suitable for daily viewing. However, in HDR, even after adjustments, it remains difficult to unequivocally recommend it for serious viewing sessions.

During calibration, we concentrated mainly on HDR content, because that's where the factory settings needed the most correction. We did not, however, neglect SDR mode, which after adjustment was brought almost to perfection. Colours are very accurate, and brightness is controlled as it should be. The biggest improvement in HDR came from fixing the white balance. Removing the excess red and blue eliminated the pinkish tint, and the image became much more natural. Skin tones, whites and all colours that had previously shifted towards pink improved. After calibration most errors fell below a Delta E of 2–3, the threshold at which the average viewer stops noticing differences with the naked eye. So the LG B6 can deliver a very accurate picture, particularly for the manufacturer's entry-level OLED model.

With native SDR content, the Panasonic W85B performs very well – tonal transitions are smooth and natural, without artificial bands or prominent contours. However, the situation is worse when it comes to lower resolution materials. It is precisely there that the television has the most difficulty with "enhancing" the image. The lack of any option in the menu that would allow for improving gradation means that with older films or materials from YouTube, one can sometimes notice slight issues with colour blending.

Fortunately, upscaling, or raising the quality of lower resolution content, performs much better. This is definitely a strong point of this model – the image is scaled cleanly and in detail, and the television handles this better than one might expect from such an inexpensive piece of equipment. This is thanks to the HCX processor, which Panasonic has been developing for years, and it is noticeable that even in the lower series it can do a good job.

The LG B6 handles lower-quality material very well. This is largely thanks to effective digital image processing, which can mask some of the source’s imperfections without overly smoothing the whole scene. The "Smooth Gradation" function proves particularly useful. It noticeably reduces posterisation, especially in dark parts of the image. The safest choice remains the Low or Medium setting. The function still effectively smooths out unsightly tonal banding, but does not yet interfere too much with fine details. Purists can of course leave it switched off. Upscaling to 4K also performs very well. Full HD and 720p material retain a good amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations only become apparent with very poor sources below 720p, where the smallest text and fine elements are not always perfectly sharp, but this applies to almost every other TV on the market.

At first glance, everything looks good – the Panasonic W85B has a 120 Hz panel and even a 144 Hz mode, so it seems that it should cope well with smooth motion. The problem arises when we look into the settings. The options for improving fluidity are supposedly present in the menu, but in practice… they don't change anything. No matter what we choose, the image looks the same. On top of that, there is a lack of BFI, or the black frame insertion mode, which on many televisions helps sharpen motion. And suddenly it turns out that despite the strong panel, the W85B offers us no real tools to adjust motion according to our needs. It’s only good when the source itself operates at a higher frequency – for example, games at 120 Hz. But when it comes to films or sports, we simply have to accept what the television shows us, because nothing more can be done about it.

One of the biggest advantages of OLED panels is the very fast pixel response time. This keeps the picture sharp and free of the visible smearing often seen on LCD TVs. However, there is a downside. During slow camera pans motion can look choppier than on LCD screens, where some of that effect is naturally masked by the slower panel. Fortunately, on the LG B6 this can be easily mitigated using the TruMotion system. With the motion smoothing set correctly you can achieve smoother motion without giving the picture an exaggerated soap opera effect.

On paper, the Panasonic W85B looks really solid. It has two full HDMI 2.1 ports, support for ALLM, variable refresh rates, Dolby Vision in games, and of course, a high refresh rate of the panel itself. Additionally, it features Panasonic's characteristic game tools bar – a "game bar" that allows you to preview key parameters and quickly change them if needed with a single click. This sounds great, but the problem arises when we turn on HDR. Here, the W85B suffers significantly, as there is practically no HGiG implementation – the television poorly manages brightness, and instead of an accurate picture, we get scenes that are too bright, sometimes even blown out. The solution? The simplest one – turn off HDR in the console settings and leave everything in SDR. And this is where it gets really interesting, as in this scenario, the W85B shows its better side. Low input lag, high fluidity thanks to 120 Hz – all of this makes gaming look phenomenal. Indeed, HDR can be forgone, but if the priority is responsiveness and smooth gameplay, the W85B offers a lot of fun.

LG OLED B6 has plenty to offer gamers; it’s simply a complete base for PS5, Xbox Series X/S or a capable PC. It has four full-size HDMI 2.1 ports with 48 Gbps bandwidth, so you can avoid irritating cable swapping when connecting several newer devices at once. It offers a full suite of synchronization technologies, from standard VRR to G-Sync and FreeSync. The screen synchronises the refresh rate seamlessly with the frame output from the console or graphics card. Of course it includes ALLM: the B6 automatically recognises when a game is running and immediately reduces latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG standard means that, after initial calibration in the console settings, the image won’t suffer from blown-out highlights or lost detail in bright areas. The cherry on the cake is the Game Bar. Instead of digging through the full menu during gameplay, a single click is enough to adjust shadow visibility, tweak selected parameters or simply check the current display mode. All of this makes the LG B6 an excellent choice for gamers.
