Sharp GP7 vs TCL A300W NXTVision

In terms of HDR, the Sharp GP7 can pleasantly surprise us. The maximum brightness around 500 nits is the threshold at which the real advantages of high dynamic range become visible. During our tests, we achieved stable values between 430 and 500 nits, which translated to clearer distinction of elements in both bright and slightly darker scenes. Additionally, there is a DCI-P3 color gamut coverage of around 95%, which allows for vibrant, visually pleasing colors. Of course, this is not the highest league, but for this price range – a big plus.

When it comes to brightness, the TCL A300W is definitely the darkest TV 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 only about 400 nits, and on test film screens, this value dropped to 350 nits. This is definitely too little to feel the true "magic" of bright HDR effects. As a consolation – the TV is equipped with a PFS LED coating (which is something like QLED), which provides very good coverage of a wide color palette, both DCI-P3 and BT.2020. Additionally, there is full support for all popular HDR formats – HDR10, HDR10+, HLG, and Dolby Vision – which somewhat compensates for the shortcomings in brightness and helps improve the overall perception of materials in this quality.

Upon taking it out of the box, in movie mode, the GP7 doesn’t perform badly at all. In HD materials, we noticed slight disturbances in white balance – drops in red and blue, which made the image have a slightly greenish tint. This is visible, 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 emerges, making colors appear less natural. On the other hand, looking from the "out of the box" perspective, these settings are not bad – just minor adjustments are needed, and we will try to improve them with special tools.

TCL A300 offers several picture modes, but without a doubt, the movie mode performs the best. Unfortunately, although it is the best choice among the available options, it is not free from errors. Both in HD and HDR content, the image has a noticeably too warm tint – leaning slightly towards pink, which is particularly noticeable in snowy scenes. Instead of pure white, we get a pinkish hue that spoils the natural perception of colors.

The brightness management doesn't perform well either. For older HD materials, the image often seems too dark – as confirmed by the inflated gamma value. Conversely, with HDR content, the effect is reversed – the image is overly brightened, which we observed in scenes from the movie Pan. This lack of consistency also affects color reproduction accuracy – a test with the ColorChecker showed that many samples deviate significantly from the reference values.

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

Calibration really makes a difference in GP7. After implementing the adjustments, we achieved a better white balance in HD content, and the colors started to look much more natural, with minimal deviations and without a clear dominance of individual colors. In 4K HDR, the change is not as spectacular, but still noticeable. The gamma has been brought to a more neutral level, although there is still a visible issue with a slight boost in the brightest details on the screen. The lack of control over dynamic tone mapping limits our maneuvering room, but nonetheless, this is a significant step forward compared to the factory settings.

After our professional calibration, the TCL A300 literally got a new lease on life. The image is no longer too warm, and the colors finally look the way they should – which was confirmed by the ColorChecker test, where the color samples finally started hitting their marks, at least to some reasonable degree. 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 still occurs, but that's a characteristic of the technology, not something that can be eliminated even after professional settings.

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

The TV can quite well scale lower quality content. Our test panels were well reproduced, and although there was minimal aliasing on small, delicate shapes (for example, thin branches), it still looked satisfactory. Additionally, the GP7 offers a "10-bit color reproduction" feature to smooth out tonal transitions in poor quality materials. It is useful, but at the expense of some details, which is why we recommend turning it on only when we are really watching something of poor quality.

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

Image scaling is also not one of the A300's strong suits. In the test pattern, the main character actually looked better than on the raw signal, but with thin lines – like fonts or background details – there was noticeable jaggedness and aliasing. On the plus side, the television does not cut off the image and has no issues with overscan, but the overall quality of scaling is rather average.

With a 60 Hz refresh rate and an average response time, it's hard to expect miraculous smoothness. In dynamic tests, like the one with the "little green man," it is evident that the image can blur and occasionally lose sharpness. For watching movies and series, this is acceptable, especially since one can use a motion smoother with three levels of adjustment. However, if we care about ultra-smooth sports broadcasts or super responsive gaming, we may feel underwhelmed.

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 picture is clear even in fast scenes. Additionally, the television offers a motion enhancement feature called "Motion," where we can find two sliders on a 10-point scale. These allow for adjusting the effect to personal preferences – from a classic, cinematic look with visible frames to a very smooth (though already unnatural) image reminiscent of a soap opera effect. Thanks to this, everyone can find a setting that suits them.

Let's not kid ourselves – the GP7 is not a television for the most demanding console gamers. Yes, it has ALLM that will automatically switch the TV to low latency mode, but it lacks VRR or G-Sync. There is also no advanced menu to facilitate the adjustment of settings during gameplay. Dolby Vision in games? Yes, but with such high input lag that it's hard to talk about comfort. If we play occasionally and do not aim for the highest standards, we can get by, but fans of technical 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. It offers practically everything you would expect from gear for gamers: two HDMI 2.1 ports with full bandwidth, 144 Hz refresh rate, VRR support, and ALLM.

The correct implementation of the HGIG mode is also a plus – something that competing Hisense sometimes struggles with. The television easily handles lower resolutions (e.g., Full HD) while maintaining high refresh rates, which will be appreciated by owners of older consoles or PCs.

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