Sharp GP7 vs TCL C6KS / C69KS / Q6CS

In terms of HDR, Sharp GP7 can surprise us pleasantly. The maximum brightness of around 500 nits is the threshold at which the real advantages of high dynamic range begin to be visible. During our tests, we achieved stable values between 430 and 500 nits, which translated to a clearer distinction of elements in both bright and slightly darker scenes. Additionally, it has a DCI-P3 colour gamut coverage of about 95%, allowing for vibrant, visually pleasing colours. Of course, it isn't top-tier, but for this price range – a big plus.

And what about HDR? Here the C6KS performs quite well and – as is becoming the theme of this review – just like in 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, video materials look good here. However, it's important to keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g. stars) appear on a dark background, the television can quite significantly dim them. The goal is simple: to eliminate blooming and maintain the best possible black. It's a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional microscopic details, the display of which could cause the screen to appear greyed out. Such is the nature of local dimming technology in this price range, and one must be aware of this. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the QLED technology slogan. 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%.

Out of the box, in movie mode, GP7 doesn't fare badly at all. In HD materials, we noticed slight disturbances in white balance - drops in red and blue that made the image take on a somewhat greenish hue. This is noticeable, for instance, on the faces of characters, which become less lifelike. The gamma is slightly brighter in places, resulting in less deep blacks. In 4K HDR content, a cooler, bluish tone also emerges, making the colours appear less natural. On the other hand, looking at it from a "straight out of the box" perspective, these settings aren't bad - a few minor adjustments will suffice, and with the help of special tools, we will try to improve them.

In contrast to the more expensive C6K model, in the tested C6KS we don't find an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests showed 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 profile 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 would give you better colours – the answer is: no, in both cases the base is the same and requires slight adjustments.

Calibration really makes a difference in Sharp GP7. After making adjustments, we achieved a better white balance in HD content, and the colours started to look much more natural, with minimal deviations and no clear dominance of individual hues. In 4K HDR, the change isn't as spectacular, but it's still noticeable. The gamma has been brought to a more neutral level, although a slight boost in the brightest details on the screen is still evident. The inability to control dynamic tone mapping limits our manoeuvrability, but nonetheless, this is a significant step forward compared to the factory settings.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, leading to a very good final effect. After calibration, we will no longer see excessive warmth in SDR scenes or overly cool tones in HDR. However, it is worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, TV shows, or YouTube materials. Evaluating the television's performance in HDR is much more difficult. Analysis of the EOTF curve suggests correct behaviour, but its practical variant shows certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times it can dim the entire scene. Calibration has therefore brought clear benefits in terms of colour, but certain limitations resulting from local dimming and the way it is controlled by the C69KS cannot be avoided, which we also observed in the C6K test.

The TV can scale lower quality content quite well. Our test patterns were well reproduced, and although there was minimal banding with fine, delicate shapes (such as thin branches), it still looked satisfactory. Additionally, Sharp GP7 offers a “10-bit colour reproduction” feature to smooth tonal transitions in poor quality materials. It is useful, but at the cost of some details, so we recommend turning it on only when we're really watching something of poor quality.

The C69KS handles upscaling quite well. The tested 576p content looks surprisingly decent – a considerable amount of detail is preserved, and the algorithm adds a subtle ‘rounding’ effect to sharp edges, making the image appear more cohesive. However, it doesn't perform as well when it comes to smoothing tonal transitions. The television practically cannot improve them, leaving the image in a rather raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

With a 60 Hz panel and average response time, it's hard to expect miraculous smoothness. In dynamic tests, like the one with the “little green man”, it’s clear that the picture can blur and occasionally lose sharpness. For watching movies and series, this is acceptable, especially since you can use the motion smoother with three levels of adjustment. However, if we care about ultra-smooth sports broadcasts or super-responsive gameplay, we might feel a bit dissatisfied.

C69KS offers a simplified motion enhancement panel in movies, allowing users to adjust the intensity of the effect using a slider. This makes it easy to tailor the smoothness to personal preferences. It also deserves credit for the ability to utilise higher refresh rates – even though the panel operates natively in 4K at 60 Hz, by lowering the resolution to 1440p, modes of 120 and 144 Hz can be enabled, on both consoles and PC. This sounds like great news, however, in practice, the image at these settings trails exceptionally badly. The effect is so pronounced that the overall experience simply appears mediocre and loses its appeal in everyday use.

Let's not kid ourselves – GP7 Sharp is not a television for the most demanding console gamers. Yes, we have ALLM, which automatically switches the TV to low latency mode, but it lacks VRR or G-Sync. We also won't find any advanced menu to help adjust settings during gameplay. Dolby Vision in games? It's there, but with such a large input lag that it's hard to talk about comfort. If we play occasionally and don't aim for the highest standards, it can be managed, but tech enthusiasts will face disappointment.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS is impressive in how well it performs for gaming. You get everything you would expect from a gaming TV: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), Dolby Vision Gaming mode, and a consistently functioning HGiG. The TV can also operate at 120 or even 144 Hz at lower resolutions, making gameplay on console or PC smoother. Additionally, there's a clear Game Bar that allows you to quickly check key settings while gaming. As a result — despite a few limitations — the C69KS can be a genuinely successful screen for gamers.
