Sharp GP7 vs TCL A300W NXTVision

In terms of HDR, Sharp GP7 can pleasantly surprise us. A maximum brightness of around 500 nits is the threshold at which the real benefits of high dynamic range become visible. During our tests, we achieved stable values between 430 and 500 nits, which translated to clearer differentiation of elements in both bright and slightly darker scenes. Additionally, the DCI-P3 colour space coverage was around 95%, allowing for vibrant, visually pleasing colours. Of course, this is not the highest league, but considering this price range – it’s a big plus.

When it comes to brightness, the TCL A300W is definitely the darkest television among all frame-style models, such as Samsung The Frame or Hisense CanvasTV – and unfortunately, this is immediately noticeable. In our measurements, the peak luminance reached a mere 400 nits, and on test film patterns, this value dropped to 350 nits. This is definitely too little to experience the true “magic” of bright HDR effects. As a consolation – the television is equipped with a PFS LED coating (which is something like QLED), providing very good coverage of a wide colour gamut, both DCI-P3 and BT.2020. In addition, it has full support for all popular HDR formats – HDR10, HDR10+, HLG, and Dolby Vision – which somewhat compensates for the lack of brightness and helps improve the overall perception of content in this quality.

Upon removing it from the box, in movie mode, GP7 does not perform poorly at all. In HD materials, we noticed slight disturbances in white balance – drops in red and blue, which made the image have a somewhat greenish hue. This is evident, for example, on the faces of characters, which become less three-dimensional. The gamma is somewhat brightened in places, resulting in less deep blacks. In 4K HDR content, a cooler, bluish tone additionally comes to the fore, making the colours appear less natural. On the other hand, looking from the perspective of "straight out of the box," these settings are not bad – only minor adjustments are needed, and with the help of specific tools, we will try to improve them.

TCL A300 offers several picture modes, but without a doubt, the best is the movie mode. Unfortunately, although it is the best option available, it is not free from errors. In both HD and HDR content, the image has a noticeably too warm hue - it leans slightly towards pink, which is particularly noticeable in scenes with snow. Instead of pure white, we get a pinkish tint that spoils the natural perception of colours.

The management of brightness is also not very good. In the case of older HD material, the image often seems too dark - which is confirmed by the inflated gamma value. Conversely, with HDR content, the effect is the opposite - the image is overly bright, which we observed in scenes from the film Pan. Such a lack of consistency also affects the accuracy of colour reproduction - a test with the ColorChecker showed that many samples clearly deviate from the reference values.

Fortunately, TCL allows for manual adjustment of settings, so we decided to check how the television would perform after our professional calibration. The effects of this adjustment are described below.

Calibration really makes a difference in Sharp GP7. After making adjustments, we achieved a better white balance in HD content, and the colours began to appear much more natural, with minimal deviations and without a noticeable dominance of individual hues. In 4K HDR, the change is not as spectacular, but still noticeable. The gamma has been brought to a more neutral level, although there remains an issue with a slight boost in the brightest details on the screen. The lack of control over dynamic tone mapping limits our manoeuvrability, but nonetheless, it is a significant step forward compared to the factory settings.

After our professional calibration, the TCL A300 has literally received a new lease of life. The image has stopped being too warm, and the colours finally look as they should – which was confirmed by the ColorChecker test, where the colour samples finally started to hit their marks, at least to some reasonable extent. It was also possible to partially correct the brightness management – the image is now more balanced and less "wobbly" between different types of content. Of course, certain limitations cannot be overcome – a slightly noticeable blooming effect is still present, but that is a characteristic of the technology and not something that can be eliminated even after professional settings.

Generally speaking: after calibration, the A300 performs significantly better and gains a completely new quality.

The television is quite capable of scaling lower quality content. Our test patterns were well reproduced, and although there was minimal banding on fine, delicate shapes (for example, 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 are truly watching something subpar.

TCL A300 handles tonal transitions in high-quality films very well, but the question arises – how does it perform with weaker material? The television is equipped with a tonal transition smoothing function, but its effectiveness can be described in one word: "random." In one scene it could work and improve the gradation, but when turned off… the effect remains the same. There is a lack of consistency and predictability.

Image scaling is also not one of A300's strong points. On the test chart, the main character actually looked better than on the raw signal, but with thin lines – such as fonts or background details – there was noticeable jaggedness and aliasing. On the positive side, the television does not crop the image and has no problems with overscan, but the overall quality of scaling is rather average.

With a 60 Hz panel and an average response time, it’s hard to expect miraculous smoothness. In dynamic tests, such as the one with the “little green man”, it’s evident that the picture can stutter and occasionally lose sharpness. For watching films and series, this is acceptable, especially as you can make use of a motion smoother with three levels of adjustment. However, if we are keen on ultra-smooth sports broadcasts or super-responsive gaming, we may feel unsatisfied.

The TCL A300 is equipped with a 144 Hz panel, which should immediately satisfy practically everyone – both gamers and sports fans. The motion is smooth and the image is clear even during fast-paced scenes. Additionally, the television offers motion enhancement functionality called "Motion," where we find two sliders on a 10-point scale. These allow you to adjust the effect to your own preferences – from a classic, cinematic look with visible frames to a very smooth (though somewhat unnatural) image reminiscent of soap opera effects. This way, everyone can find a setting that suits them.

Let's not kid ourselves – GP7 Sharp is not a television for the most demanding console gamers. Yes, it has 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 assist in selecting settings during gameplay. Dolby Vision in games? It's there, but with such a high input lag that it's hard to speak of comfort. If we play occasionally and are not aiming for the highest standards, it can be managed, but fans of technological innovations will be disappointed.

TCL A300 is a television designed not only to transport us to a digital art museum but also to a full-fledged gaming world. Here, we find practically everything one could expect from gaming equipment: two full-bandwidth HDMI 2.1 ports, 144 Hz refresh rate, VRR support, and ALLM.

The proper implementation of the HGIG mode also deserves praise – something that competitor Hisense sometimes struggles with. The television easily handles lower resolutions (e.g., Full HD) while maintaining high refresh rates, which older console or PC owners will appreciate.

In addition, there is an attractive and clear GameBar that facilitates quick access to settings for gamers. The A300 is really well-prepared for top-level gaming – it's just a shame that issues with smearing slightly tarnish its overall image as a gaming device.
