TCL P755 vs Hisense E7NQ PRO

TCL P755 provides average HDR effect quality. The maximum brightness of the TV is slightly below 300 nits. Such brightness limits the intensity of bright areas in HDR content. In practice, this means that bright elements may not be sufficiently pronounced, affecting the overall impression of contrast. However, the TV offers wide coverage of the DCI P3 colour gamut, reaching about 93%. As a result, colours are vibrant and saturated, significantly improving colour reproduction quality in HDR content. Despite the limited brightness, the wide colour range allows for richer and more realistic shades.

Based on the luminance chart, which indicates around 550 nits, it can be considered that Hisense E7NQ PRO theoretically has the potential to somewhat "enchant" us with its HDR image. Testing various scenes from movies, we noticed that the television continually tries to balance between maintaining appropriate brightness and preserving the deepest blacks. In favourable conditions – such as in a scene from “The Meg”, where the screen is flooded with bright light – this brightness can indeed impress us. At such moments, we feel that HDR actually adds that "something" to the image. Unfortunately, when difficult shots with fine, bright elements on a dark background appear on the screen, the situation looks much worse. Brightness then drops to 200-300 nits, which is definitely too little to really distinguish HDR from standard SDR.

It is clear that the television is trying, but the hardware limitations – mainly the small number of local dimming zones – prevent it from fully spreading its wings. The end result can therefore be quite inconsistent and as average as the contrast tests. On the plus side, it deserves credit for its impressive coverage of the DCI-P3 colour gamut at 97%. This allows the television to present a truly wide range of colours, which, in the right scenes, can give us at least a glimpse of the real HDR effect. It’s just a shame that the whole picture isn't complemented by better control of brightness and contrast.

The colour reproduction in the P755 in "Cinema" mode, although it is the best factory setting, leaves much to be desired. The biggest issue is the white balance, where the chart clearly shows a spike in the red colour and a drop in the green colour. This leads to a shift in colours towards red, causing the colours on the screen to appear less natural and may look incorrect, especially in scenes with a white or neutral background. This is confirmed by the "Colour Checker" test, which reveals that the colours are indeed shifted towards red, affecting the realism of the image and reducing the perception of colour depth. In terms of contrast, the gamma chart analysis shows significant fluctuations, particularly in the dark areas of the image, where values drop below the optimal level of 2.4. As a result, darker areas may be displayed brighter than they should be. Additionally, the EOTF curve, responsible for brightness reproduction, sits slightly above the reference curve. The graph shows a slight increase in brightness to about 50%, after which there is only a minor drop. This leads to excessive brightness enhancement in the mid-range of the image and may result in loss of detail and distortion in brighter scenes.

When we took our copy of Hisense E7NQ PRO out of the box, we immediately started checking the available picture modes. Among them, the Filmmaker mode seemed the most promising, although it wasn't without its flaws. With standard SDR content, we noticed a clear tendency to overemphasise red, making the picture appear unnaturally warm. This was particularly evident in the comparison photo attached below. Conversely, when we switched to HDR content, the situation took a turn in the opposite direction. This time, blue was dominant, and there was hardly any red, resulting in a cool, at times almost "store-like" appearance — although not as drastic as in modes specifically designed for showcasing in displays. As a result, in our tests assessing colour reproduction, these disturbances in colour balance led to significant errors.

Additionally, the television had trouble reproducing brightness characteristics. At lower resolutions, it clearly brightened the darkest elements of the image, and with HDR content, the brightness curve (eotf) simply wouldn't align as it should. Initially, the television excessively darkened the smallest details, only to then over-brighten larger areas. Fortunately, the E7NQ PRO provides us with a lot of calibration tools, so knowing there was potential within it, we decided to take matters into our own hands and try to set it up to eliminate these issues.

After calibration, the colour reproduction on the television significantly improves when it comes to SDR content. The colour curves are now close to the ideal value, and the gamma is more stable. Although the dip at the beginning of the graph to the values is still present, the overall accuracy of colour reproduction is much better. The “Colour Checker” test shows that most colour samples have errors below level 2, indicating improved colour fidelity. A few deviations are present, but generally, the colours are now more realistic and consistent with reality.

Calibration also brings improvements in HDR content. The white balance has been corrected, translating to more natural colour reproduction. The EOTF curve, although now closer to the reference curve, still shows a slight boost in brightness at the beginning of the graph. This leads to minor distortions in very bright scenes, but the overall tonality and detail have been enhanced. Dynamic tone mapping works more effectively, improving image quality in bright areas and preserving more details.

Although the image from the device does not achieve full perfection, calibration brings significant improvement. After adjusting the settings, the television performs much better, offering more realistic and accurate colour reproduction in SDR and HDR content. While some shortcomings can still be noticed, calibration effectively eliminates many previous issues, ensuring better image quality and more natural colours.

Thanks to the tools available in E7NQ PRO, we've managed to squeeze a pretty decent image out of it, especially with lower quality content. After fine-tuning the white balance of the SDR materials, the colours look much more natural, and what we see on the screen seems closer to the vision the producer intended to present. Additionally, we've improved the brightness characteristics (Gamma), so the TV no longer tends to over-brighten, and everything looks noticeably better than before our intervention.

With HDR materials, we also achieved some improvements, although it's not as rosy here. Yes, the white balance has approached an acceptable level, but the problem lies elsewhere. It's about the EOTF curve, which is how the TV manages brightness and tonality of the image. At first glance, one might think that the biggest issue concerns only the mid-tones, which are overly brightened. However, after more detailed testing and activating the EOTF curve visualisation filters, it becomes clear that the receiver has a tendency to brighten the entire screen. This seems to be a limitation due to the small number of local dimming zones and generally modest brightness management capabilities. Such hardware limitations are simply insurmountable. Nonetheless, after our calibration, the image is noticeably better than at the start. One just needs to be aware that in terms of contrast and brightness management, this model has its limits, which even a good calibration cannot fully overcome.

The “Gradual Smoothing” function works quite well, effectively eliminating visible boundaries between different shades of the same colour. Thanks to it, tonal transitions are smoother. Unfortunately, this function is not available in HDR mode, which can affect the quality of tonal gradation in higher dynamic range materials.

In the case of image scaling, the television does not perform its best. There are noticeable edge cut-offs, particularly evident on the model's figure and the branches of trees. The blurring of details in these areas affects the overall sharpness of the image. This may be noticeable when watching content in a lower resolution. Additionally, SD quality image is displayed with slight cropping at the top as well as the bottom.

When it comes to the tonal transition smoothing function in lower quality materials, the “smooth and gradient image” feature in Hisense E7NQ PRO unfortunately does not impress. At the lowest setting, the change is barely noticeable – it's more of a cosmetic improvement. Switching to “Medium” mode does produce a noticeable effect, but it's still nothing special, and the TV starts to excessively interfere with other elements of the image, which can look unnatural.

Image scaling is also rather average. On the test screen, where a portrait of a model and text are displayed, there are slight frays at the edges, making the overall presentation less smooth and aesthetic than we would expect in this class of device. It's just hard to talk about really effective improvement of lower resolution quality here.

The television offers decent, though not perfect, results in terms of motion smoothness. In the case of movies, the television has a "Flicker Reduction" feature that allows for adjustment of motion smoothness on a scale from 1 to 10. With this option, we can tailor the image appearance to cinema or more theatrical preferences (with lower or higher speed).

Thanks to the use of a 144 Hz panel, E7NQ PRO performs exceptionally well with almost any type of content. Whether we're watching fast-paced matches, dynamic games or action films – the fluidity of motion leaves a good impression. When it comes to movies, the manufacturer has equipped the TV with two key tools: “motion blur reduction” and “judder reduction.” Each of these functions can be adjusted on a scale from 1 to 10.

At lower values, the processing is subtle, barely noticeable, and gently smooths motion without ruining the cinematic character of the image. The higher we move up the scale, the more clearly the TV interferes with the presented material, smoothing motion more aggressively, thereby minimising any judders or micro-cuts. Conversely, the highest settings can resemble the so-called “soap opera effect,” which makes the image look overly smooth, slightly losing its cinematic atmosphere. Thanks to this scale, however, we can find a happy medium, adjusting motion fluidity to our own preferences.

The device offers a range of features useful for gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the TV to low latency mode, significantly improving responsiveness to commands from the controller and minimising input lag. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating the tearing effect and providing smoother gameplay. Dolby Vision for gamers enhances picture quality by offering better colour and contrast reproduction in games that support this format. The Game Bar feature allows quick access to game settings and monitoring of key parameters such as response time.

However, the TV has some limitations. The 60 Hz panel prevents the display of signals with higher refresh rates at different resolutions, which may affect the fluidity of the image in dynamic games. Additionally, the lack of support for G-Sync technology for PC may impact the quality of gameplay on a computer. It is also worth noting that the HGiG mode, which aims to improve image quality in HDR games, does not work correctly on this model, negatively affecting the visual experience in HDR-supported games.

If we sometimes like to turn on the console and immerse ourselves in the world of games for long hours, E7NQ PRO can make a really good impression. Thanks to the 144 Hz refresh rate, the gameplay is surprisingly smooth, and support for HDMI 2.1 and VRR ensures that the image doesn't "tear" even during the most dynamic actions. Additionally, there's ALLM, which automatically sets the lowest latency as soon as we switch to the console – so we don’t have to fiddle around in the options ourselves.

A big plus is also the ability to launch games in Dolby Vision, which makes colors and contrast simply look better. Hisense has also included a clear "gamebar," allowing us to continuously monitor the key parameters and change settings without leaving the game. The only thing we might slightly regret is the lack of HGIG support. It may not be a crucial element, but for some gamers, it can matter if they aim for the most faithful reproduction of the creators' vision. Nevertheless, in practice, the E7NQ PRO performs excellently and delivers truly enjoyable gaming experiences.
