Philips PUS7000 vs TCL A400 PRO

Unfortunately, the PUS7000 is not suitable for watching HDR content. This screen is simply too dark. A brightness level of 200 nits is not enough to correctly display such a format. Even if a HDR signal message appears on the screen, the image will resemble a regular SDR recording. Therefore, it's better to stick with the latter format to avoid issues in displaying bright scenes, which you can read about below. The situation is not improved by the fact that this is a classic LCD model without additional layers to enhance colors, such as QLED or PFS. As a result, colors in HDR may appear washed out. Ultimately, this gives a worse effect than in the standard SDR format, which is simply better suited to the capabilities of this panel.

The TCL A400 Pro is a moderately bright TV. Its peak brightness reaches about 600 nits. That level already allows for a real HDR effect and in many movies it does produce a noticeably more attractive picture than SDR. However, it is not a level that overwhelms by brightness alone. The A400 Pro is not one of those TVs that "attack" the viewer with a powerful flash in every dramatic scene. The biggest limitation is visible with small bright elements on a dark background. Due to rather aggressive control of the dimming zones, the TV can significantly reduce their brightness — in extreme cases down to around 100 nits. That means small lights, sparks, stars, or single highlights can be much less visible than they should be. That said, this is not done without reason. The A400 Pro does this to keep blacks as deep as possible and to limit haloing around bright objects. It's a deliberate compromise: the TV more often chooses deeper blacks over maximally bright, point-like highlights. On one hand this is understandable, especially with a limited number of dimming zones, but on the other hand you should be aware that the HDR effect will not always be as strong as the peak brightness alone would suggest.

On the plus side, the colors are worth noting. The PFS LED filter used here, marketed by the manufacturer as QLED, produces suitably saturated colors. Our measurements showed about 94% coverage of the DCI-P3 gamut and about 74% of BT.2020, which is a solid result for this class.

We tested the television in movie mode, which theoretically should provide the best and most natural colors. And indeed, this mode is quite correct; however, after connecting the calibration equipment, its biggest flaw became apparent. The PUS7000 has significant deficiencies in displaying red. Poorly tuned white balance and too low saturation of this color cause the image to appear too cool. As a result, one might get the impression that the displayed content is simply lacking in vibrant colors. The situation is exacerbated by the fact that both SDR and HDR content are excessively brightened. This is confirmed by the gamma curve and EOTF graphs, which show that the television displays the image brighter than it should. This causes scenes to lose their depth and may appear somewhat washed out. Fortunately, the Philips menu offers many functions to improve these aspects, so we immediately proceeded to calibration to see what could be squeezed out of this screen.

As standard, we carried out color measurements in the best-calibrated mode, Filmmaker Mode, the one that is supposed to be closest to the creators’ intent. The A400 Pro, of course, also offers other picture modes, but in practice they suffer from much larger color errors and alter the image character more strongly. We won’t go into those modes in detail in this part of the test. So how does the factory color reproduction perform? In short: really very well. In fact, looking at our measurement results, it’s excellent. Both the white balance and the luminance response were set surprisingly precisely. The errors were so small that during testing we genuinely rubbed our eyes in disbelief. Such good out-of-the-box settings don’t happen often, even in TVs operating in Filmmaker Mode. All the more reason to praise TCL, because the A400 Pro right out of the box can produce an image very close to how the source material should look. The results were so good that you could easily think someone had already paid extra attention to that unit and tried to calibrate it.

Our nitpicking really comes down to just one thing. In SDR content the image was slightly brighter than the reference for a dark room, because the factory gamma was set closer to 2.3 than to 2.4. It’s not a big error and most viewers probably won’t even notice it.

However, it should be noted that we’re talking about our specific review sample. With factory colors there can always be some variation between units, production batches, or screen sizes. So we don’t assume that every A400 Pro will look identical straight out of the box.

After professional calibration, it is clear that the PUS7000 responds well to image adjustments. In this price range, this is not a given. The effects should be assessed in two scenarios, depending on what content we plan to watch. SDR performs the best. After our corrections, the image looks really good. Most color errors fell below level 3, which is the threshold at which distortions typically become visible to the naked eye in measurements. Movies, series, sports, and regular television present themselves naturally, without unpleasant deviations. If someone primarily watches classic channels or streaming in HD quality, the difference after calibration will be noticeable immediately. However, it must be made clear that the PUS7000 is still not a television suitable for sensible HDR, and calibration does not change much here. The reason lies in the hardware: colors remain too undersaturated. The television lacks solutions that expand the color gamut, such as PFS filters or a quantum dot layer, so the panel simply cannot show the intense colors required by HDR. This is most evident in reds, which still look pale. This limitation cannot be bypassed with menu settings, as it results from the design of the backlighting and the panel itself.

Despite its excellent factory tuning, we couldn't resist checking how the TCL A400 Pro would respond to a professional calibration. Since the starting point was so good, we were even more curious whether we could squeeze even more out of this TV. And here we have to boast: we managed to bring our unit to absurdly low color errors. Results below 1 are something you don't see every day, even on very good TVs. Such results are more often associated with professional reference monitors than with a lifestyle TV for the living room. In terms of white balance and color reproduction, the A400 Pro after calibration simply performed outstandingly. The only thing we can pick at after a deeper analysis concerns the brightness behavior. The TV can manipulate luminance levels depending on the content being displayed, and quite often the image is a bit darker than it should be according to the standard. This most likely stems from the way the Mini-LED backlight and local dimming algorithms work in this model. However, that doesn't spoil the overall impression, because in terms of color precision alone the A400 Pro after calibration reached a level we really didn't expect.

The PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths out unwanted tonal transitions even at a low setting. However, it has a flaw: if the action is too aggressive, it can introduce undesirable artifacts on the screen. It’s a good idea to experiment with this setting to find the sweet spot between a smooth image and detail clarity.

The upscaling, which is the enhancement of lower quality materials to 4K, is adequate. The image after processing is very "soft," which is typical for almost all Philips televisions. The edges are plastic and smooth, making the image look cohesive. If someone finds it too soft, it can always be adjusted with the sharpness slider in the menu to achieve a more pronounced effect.

Digital video processing is unfortunately one of the weaker points of the TCL A400 Pro. That doesn't mean the TV performs badly, but it's hard to call it anything clearly above standard. The upscaling itself is adequate: edges are smoothed fairly well, the image doesn't look overly sharp or pixelated, and lower-quality content can be watched without major discomfort. At the same time the overall look is slightly soft and it lacks the precision that the best image processors in more expensive TVs can deliver.

Much worse, however, is its handling of tonal transitions caused by heavy compression. TCL equipped the A400 Pro with a "Gradual Smoothing" feature that in theory should reduce visible color banding and artifacts in lower-quality content. In practice its effectiveness is very limited. It does not improve tonal transitions in any noticeable way, and at higher settings it can also smooth out image details, giving the picture an artificial, slightly blurred character. For that reason we think it's best to leave this feature off. The A400 Pro handles basic image scaling decently, but if you often watch heavily compressed content with visible posterization, this model won't be one of the best choices.

In this regard, we don't really have any good news. It might seem that the biggest downside is the lack of a 120 Hz panel, but in this price range, that's actually standard, and it's hard to expect more. However, the worst part is that the TV does not have any motion smoothing features. There are no supporting systems for either movies or sports. We have to accept that the image on the PUS7000 is processed "raw." This means that during dynamic scenes or fast camera movements, the motion may appear choppy or unclear. We have no way to enable any smoother that would soften this effect.

The TCL A400 Pro is equipped with a 144 Hz panel, but in practice we're most interested in how it performs at 120 Hz. That's the refresh rate used by most consoles today, as well as many sports broadcasts and high-frame-rate content. In this range the TV performs quite well. Motion clarity is really good, especially after properly configuring the motion smoothing. The "Motion Clarity" feature improves smoothness. Its settings include two sliders that let you tailor the motion smoothing to your preferences — separately for lower- and higher-frame-rate material. That way you can achieve either a more cinematic look or a noticeably smoother picture. If you don't want to tweak settings manually, you can use presets such as low, medium, high, cinema, or nature.

Although the PUS7000 is not marketed as a gaming TV, it does not perform as poorly in this category as one might expect. While there is no support for 120 Hz refresh rates, which is understandable at this price point, the manufacturer has included several important features that genuinely improve the comfort of playing on a console. The most significant of these are VRR and ALLM technologies. VRR is responsible for synchronizing the screen with the number of frames generated by the console. This prevents the image from "tearing" and keeps it consistent even during sudden frame drops in the game. In turn, ALLM is a solution that automatically switches the TV to the lowest latency mode right after detecting a signal from the console. All of these parameters are easily accessible thanks to the Game Bar feature. This is a special control panel for gamers that can be brought up on the screen at any time. It allows for a quick overview of current settings and connection status without interrupting gameplay, which is a very convenient solution.

When it comes to features for gamers, the TCL A400 Pro performs excellently. The TV has practically everything you can expect from a gaming TV today: 4K support at high refresh rates, VRR, ALLM, correct implementation of HDR formats in games, including Dolby Vision, and HGiG. Because of that it works well with both next-gen consoles and PCs. Another plus is the inclusion of a Game Bar, a special panel with the most important settings for gamers. From it you can quickly check basic signal information, refresh rate, and active features, and also adjust the look and behavior of some settings to your own preferences. This is a solution that may not change picture quality by itself, but it greatly improves the convenience of using the TV while gaming.

The only thing to complain about is the number of full HDMI 2.1 ports. The A400 Pro has only two such ports out of four, and one of them also functions as eARC. In practice this means that if someone wants to connect two next-gen consoles and a soundbar, they may hit some limitations. In that scenario you'll have to either swap devices or use extra equipment, for example an AV receiver or a soundbar with HDMI inputs. Despite this, it's hard not to rate the A400 Pro very highly as a gaming TV. The gaming feature set here is really powerful.
