LG QNED86A / QNED85A / QNED87A vs TCL P7L / P79L

Against a backdrop of contrast and black, the brightness of the QNED86A and the overall HDR effect perform much better. This is a television that can achieve around 700 nits under the best conditions, so in terms of luminance alone, there is nothing to be ashamed of. As a result, scenes with strong lights, explosions, flashes, or bright parts of the landscape look clear and can make an impression. Interestingly, even in more challenging moments with small, contrasting elements on the screen, the television manages well with their backlighting, and the details are quite visible. The problem arises when there are many dark tones. The lack of effective local dimming causes the black to practically disappear, and instead, we get a grey haze spreading across the entire screen. This kills the sense of depth and makes the image look flat, as if it lacks a cinematic character. In bright animations or colourful family films, this will not be a problem, as vibrant colours and bright light dominate. But in horrors or productions set in darkness, these limitations are very strongly felt. As a comfort, it is worth adding that the QNED86A is actually a QLED television with a PFS LED filter, which gives it very good coverage of a wide colour gamut. Both the DCI-P3 palette and the broader BT.2020 perform really well here. This makes the colours in HDR films saturated, juicy, and with the appropriate depth – even if the black itself disappoints, the colours can save the viewing experience and make the image look attractive.

The biggest limitation of the TCL P7L in HDR is simply brightness. The TV does not have much luminance headroom, so strong highlights, the sun or small light sources can't clearly 'pop' out of the picture. As a result, even well-produced HDR material looks fairly restrained and, in terms of dynamics, is closer to good SDR than to what brighter models show. That does not mean the P7L completely fails at HDR. The issue is primarily a lack of backlight power.

Looking at colours, the situation is a little better. The TV covers around 91% of the DCI-P3 gamut and about 68% of the wide BT.2020 colour space, so for this price class the colour range is quite respectable. TCL markets this model as QLED, although the nature of the solution used is closer to backlighting that uses a PFS phosphor than to a classic quantum-dot layer. What matters most to the viewer, however, is the effect: more saturated colours are on offer.

We primarily tested the QNED86A in Filmmaker mode, which is designed to provide the most faithful picture. Unfortunately, right out of the box, there were quite a few shortcomings. The most noticeable was the poorly tuned white balance – there was a lack of blue, causing the overall image to take on a slightly yellowish, and at times even orange hue. An even bigger problem turned out to be the way the television manages brightness. Due to its technical limitations – specifically, local dimming that only works along the edges of the screen – the QNED86A tends to oversaturate entire scenes. This is where the flattening effect we mentioned earlier comes from. Instead of clear depth and contrast, we get something akin to “boosted brightness,” which can strain the eyes over time.

In Film mode the TCL P7L performs quite respectably without major changes to the settings, particularly with ordinary SDR material. White balance is relatively even, though as brightness increases there is a slight rise in red and blue and a touch too little green. This does not, however, produce a strongly visible tint and most colours remain close to their reference points. The Colour Checker confirms this, with a large portion of errors falling below the level that should be particularly noticeable during normal viewing. We have more reservations about the gamma response. In the darkest parts of the image the TV runs it noticeably above the reference value, so some shadow detail can be a little too subdued. The characteristic then calms down and across much of the range it is close to the intended behaviour. As a result SDR generally looks natural, but in dark scenes the P7L can lose some subtlety.

In HDR the factory calibration is less precise. As brightness increases the excess of blue becomes more pronounced, which can make the image look cooler than it should. The number of larger colour deviations also grows, particularly in brighter hues. As for the EOTF curve itself, it is handled fairly conservatively, with the TV showing the image darker than the reference across much of the range. For such an inexpensive model, the factory Film mode settings are not bad.

What has been saved in the QNED86A6A is undoubtedly the colours. After calibration, the white balance was set with great precision, ensuring that deviations on the Colour Checker palette mostly did not exceed the visibility threshold for the human eye. In other words – the hues finally looked natural, without the strange yellow or orange tones that previously spoiled the perception. Unfortunately, even the best calibration cannot circumvent the structural limitations. The already very modest number of local dimming zones and their unfortunate placement mean that the analysis of the EOTF curve in films still showed clear over-brightening of scenes. The picture tended to flatten, lacking cinematic depth. Fortunately, this effect is not so noticeable in older productions or in SDR content. There, the calibration truly makes a difference and allows one to harness the QNED so that the image can be appealing. However, the specifics of this construction – especially the issues with contrast – cannot be completely bypassed.

After calibration the TCL P7L can deliver a genuinely pleasant picture, especially with conventional SDR material. We managed to even out the white balance very well, and the gamma curve now tracks close to the target value of 2.4. This is also reflected in the colour measurements: most errors have fallen noticeably, and in everyday viewing it is hard to point to any obvious inaccuracies. Films, series, YouTube and ordinary broadcast TV therefore look more natural, without unnecessary warmth or a cool tint. For a model in this price bracket the SDR performance is really very good.

With HDR the situation becomes more complicated. Calibration helped improve the white balance and tidy up some deviations, but here the panel's limitations become increasingly apparent. The P7L has relatively low brightness and cannot maintain adequate luminance for more saturated colours, so some errors remain even after careful tuning. In other words, settings can improve the way the TV interprets the signal, but they cannot overcome its physical limits. That is why calibration makes most sense for this model primarily in SDR.

If someone is worried about potential "steps" when blending colours, there is a simple way in the QNED86A to address this. Just activate the feature called Smooth Gradation and set it to a medium level. Then the television really smooths out all those unwanted transitions quite well – especially in older productions – and it does so in a way that film grain doesn't disappear, nor do strange artefacts appear. In other words, it can be used without concern.

The upscaling itself also performs quite well. Of course, there are no miracles here – with lower quality sources, you can notice characteristic ringing. Fortunately, there is a sharpness slider in the menu, and if someone prefers a more "soft" image, it can be quickly adjusted to personal taste.

In this respect the TCL P7L performs surprisingly well, especially for such an inexpensive TV. The banding-reduction feature, which in many budget models does little or nothing, actually manages to improve the picture here. It does not remove all banding entirely, but it can noticeably reduce posterisation and make more challenging gradients look more natural. At this price point that’s a genuinely pleasant surprise. Upscaling itself also performs well. Lower-resolution material is scaled correctly, without over-sharpening or adding artificial outlines around objects. Of course the P7L won’t turn a very poor source into a 4K-quality image, but for regular TV the result is simply solid. For a model in this class there is little to criticise.

The QNED86A is equipped with a panel boasting a refresh rate of 120 Hz, so it can be said from the outset that it is suitable for both sports and gaming. And indeed, it is – the image appears smooth, and motion blur is not particularly intrusive. IPS panels have always had some issues with this, and here too, slight blurring can sometimes be noticed, especially in very dynamic scenes, but it is not something that ruins the viewing of a match or a fast-paced game. For cinema and sports fans, LG has included the traditional TruMotion smoothness enhancer. In the menu, we have two sliders – one for movies (De-Judder) and the other for sports (De-Blur). The first adds missing frames and can be adjusted to modify the character of motion – from raw, cinematic to a smoother, more ‘theatrical’ look. The second improves sharpness during dynamic actions, so it's worth turning it up a bit if you watch a lot of sports.

The TCL P7L uses a panel with a native 60 Hz refresh rate at 4K resolution, and that's how it should be regarded in everyday use. When watching films the TV mainly offers frame interpolation, so it can smooth motion and reduce the characteristic judder, but it does not deliver the fluidity typical of true 120 Hz panels.

In terms of gaming, the LG QNED86A6A is a complete tool. It features four HDMI 2.1 ports with full bandwidth of 48 Gb/s, which means that whether you connect a PlayStation 5, Xbox Series X, or a powerful PC, everything will run in full 4K at 120 Hz with support for all functions. This is a significant advantage, as some competitors still only offer two such ports, which can be troublesome with multiple devices. It also includes VRR, or variable refresh rate, which eliminates screen tearing, as well as ALLM, which automatically activates game mode when the console is turned on. Dolby Vision Gaming is also included, along with proper implementation of the HGiG format, so titles that support these formats look more vivid and detailed. On top of all this, there is the Game Optimizer – a sort of control centre for gamers. From this interface, you can view picture parameters in real-time, quickly change modes, activate additional features, or adjust image settings to your personal preferences. The LG QNED86A6A essentially has everything one could expect from a modern gaming television.

For such an inexpensive TV, the P7L has quite a lot to offer gamers. It has ALLM, VRR, Dolby Vision for gaming, and TCL also includes its Game Bar, which lets you quickly check the key information or change some settings without leaving the game. Not everything is perfect, though, because HGiG doesn’t work here as it should, but at this price point it’s hard to complain about the feature set. The most interesting part starts when you give up 4K. At that resolution the TV runs at up to 60 Hz, but at 1440p and 1080p it can display at 120 Hz. And that’s not just a line in the specs. In fast-paced games that support that frame rate you can really notice the improvement in smoothness, so if you value smoother motion more than maximum image detail, that mode can make a lot of sense. Of course, that doesn’t turn the P7L into a proper 120 Hz TV. Even so, those extra modes are exactly what make the P7L perform very well for gaming.
