Philips PUS7009 (VA) vs TCL C6KS / C69KS / Q6CS

In terms of HDR effect quality, Philips PUS7009 performs very poorly. A brightness level of 250 nits does not allow one to enjoy HDR effects, and the image resembles more of a standard SDR. There is no question of dynamic effects or vivid light bursts. The coverage of the DCI-P3 colour gamut is only 75%, which is definitely insufficient. The lack of full colour coverage means that the colours are not as vibrant as they should be, resulting in a flat and unconvincing image. There are no aspects for which this model could be praised in the context of HDR.

And what about HDR? Here, the C6KS performs quite well and – as has become a recurring theme of this review – identically to the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect, and generally, the video materials look good here. However, one must keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g., stars) appear against a dark background, the television can dim them quite significantly. The goal is simple: to eliminate blooming and maintain the best possible blacks. This is quite a reasonable compromise. Most viewers will definitely appreciate deep, "true black" more than additional micro-details, the display of which could cause the screen to appear greyed out. This is the nature of local dimming technology in this price range, and one must be aware of it. It is also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the slogan of QLED technology. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92% here.

The television was tested in movie mode, which – despite its name – does not provide accurate image display. The white balance in both 4K HDR and HD/SDR content shows drops in red, causing the image to appear cooler and the colours to lose their natural warmth. The gamma brightness characteristics and the EOTF curve confirm that the television struggles to maintain appropriate brightness – it boosts it significantly, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where everything looks as if it has a milky filter applied. Additionally, the limited coverage of a wide colour palette also does not favour quality – color checker tests indicate significant colour variations, making it difficult to achieve faithful image reproduction.

Unlike the more expensive C6K model, the tested C6KS does not have an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture characteristic to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K gives you better colours – the answer is no, in both cases the base is the same and requires slight adjustments.

After calibration, the image improved significantly, especially in terms of white balance, which is now more stable, and the hues have become more natural, eliminating the previous impression of an overly cool image. The calibration brought noticeable benefits in terms of tonality – the shadows and midtones are now more realistic, and the overall effect appears more harmonious. Unfortunately, hardware limitations still affect image quality. The brightness characteristics remain problematic, despite our efforts, and due to poor coverage of the DCI-P3 and BT.2020 colour spaces, delta E errors are still at a high level. Although the calibration improved some aspects, the television still does not allow for complete satisfaction.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, resulting in a very good final effect. After calibration, we will no longer see excessive warming of scenes in SDR or overly cool tones in HDR. However, it is worth noting the brightness characteristics. In SDR content, it is hard to have any objections – the image looks very good, especially in older films, television programmes, or materials from YouTube. It is significantly more challenging to evaluate the television's performance in HDR. Analysis of the EOTF curve suggests correct behaviour, but its practical variant reveals certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times, it can dim the entire scene. Thus, calibration brought clear benefits in terms of colour quality, but certain limitations resulting from the local dimming operation and the way it is controlled by the C69KS cannot be overlooked, as we also saw in the C6K test.

When it comes to tonal transitions in low-quality material, the function called "Distortion Reduction" (the "minimum" setting) effectively improves gradation, eliminating unattractive tonal transitions. However, this setting on Philips televisions is quite aggressive – while it does not blur grain or good quality material, it can introduce undesirable effects and blur elements that should remain sharp when the signal is poorer.

In terms of image scaling, Philips PUS7009 performs decently. A significant advantage is the absence of cropped image edges, meaning no overscan, which allows for the display of the full frame without loss. The image is noticeably enhanced, making characters and backgrounds, such as the model or branches in the background, look quite detailed and natural, even with lower quality signals. Although scaling is not perfect, as it can remove desired details in the distance, the effects are good enough for most users to be satisfied.

The C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a considerable amount of detail is retained, and the algorithm adds a slight "rounding" effect to sharp edges, making the image appear more cohesive. The performance in smoothing tonal transitions is less impressive. The television practically cannot improve them, leaving the image in a rather raw state. With older material, this can be quite tiring, as the lack of additional processing highlights any imperfections.

Philips PUS7009 does not have motion smoothing capabilities, which means there is no option to adjust the image for a more choppy or smoother, cinematic effect. Such features could positively influence the reception of dynamic scenes. In terms of motion blur, this model is equipped with a 60 Hz VA panel, which offers slightly worse results than the variant with an IPS panel. The VA panel introduces minimally greater motion blur, although the differences are not significant and should not pose a problem for most viewers.

C69KS offers a simplified motion enhancement panel in films, allowing the adjustment of effect intensity with a slider. This makes it easy to match fluidity to personal preferences. The ability to use higher refresh rates is also a plus – although the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p enables 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, however, in practice, the image at these settings exhibits significant motion blur. The effect is so pronounced that the overall presentation appears merely average and loses its appeal for everyday use.

In terms of compatibility with consoles, Philips PUS7009 is likely to satisfy casual gamers. Although equipped with HDMI 2.0, it offers features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the television to low latency mode, which speeds up responses during gaming, while VRR adjusts the refresh rate to minimise screen tearing. Game Bar provides quick access to gaming settings and monitors key parameters, although it visually falls short compared to competing solutions. However, more demanding gamers may feel underwhelmed. Philips PUS7009 does not support advanced HDR formats in games, and the 60 Hz panel limits the ability to display smooth and detailed images in dynamic scenes, which may not satisfy fans of fast-paced action games.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything one can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a well-functioning HGiG. The television can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on a console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings while gaming. As a result — despite a few limitations — the C69KS can be a really successful screen for gamers.
