Hisense E7Q / E79Q vs TCL P7L / P79L

The Hisense E7Q / E79Q is a television with average brightness, with a peak luminance level of around 350-380 nits. This is an absolute minimum that allows for HDR content to be viewed in a way that is close to the creators' intentions, although without a distinct "wow" effect. Synthetic test results on white screens have been confirmed in practice – in film scenes, the bright parts of the image are stable and quite uniform, but it's hard to speak of a true "light punch." In everyday use, for example, when watching Netflix or YouTube, the HDR effect is acceptable and is perfectly sufficient for most users. However, it must be stated clearly – this is not the level of top-end screens, and one should not expect that in this price range. Fortunately, the Hisense E7Q / E79Q has an advantage that allows it to gain quite a few points: it features a PFS LED QLED panel, utilising an additional phosphor layer that improves colour reproduction. The measured range of the DCI-P3 colour gamut is about 92%, which means that colours in most scenes are vibrant, well-saturated, and pleasant to the eye, particularly for this price bracket.

The biggest limitation of the TCL P7L in HDR is simply brightness. The TV does not have much luminance headroom, so strong highlights, the sun or small light sources can't clearly 'pop' out of the picture. As a result, even well-produced HDR material looks fairly restrained and, in terms of dynamics, is closer to good SDR than to what brighter models show. That does not mean the P7L completely fails at HDR. The issue is primarily a lack of backlight power.

Looking at colours, the situation is a little better. The TV covers around 91% of the DCI-P3 gamut and about 68% of the wide BT.2020 colour space, so for this price class the colour range is quite respectable. TCL markets this model as QLED, although the nature of the solution used is closer to backlighting that uses a PFS phosphor than to a classic quantum-dot layer. What matters most to the viewer, however, is the effect: more saturated colours are on offer.

In Filmmaker mode, the Hisense E7Q / E79Q television was truly impressive. After the first measurements, it became clear that the white balance was quite well tuned, with the only minor deviation being a slight tendency towards a purple tone, which we mentioned earlier. However, this did not significantly impact the overall character of the image – it remained coherent and pleasant to view. A much larger issue turned out to be the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television noticeably brightened the image, flattening the contrast and diminishing its depth. Gamma values could drop from the reference 2.4 to around 1.9, making the image look as if it were covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through calibration.

In Film mode the TCL P7L performs quite respectably without major changes to the settings, particularly with ordinary SDR material. White balance is relatively even, though as brightness increases there is a slight rise in red and blue and a touch too little green. This does not, however, produce a strongly visible tint and most colours remain close to their reference points. The Colour Checker confirms this, with a large portion of errors falling below the level that should be particularly noticeable during normal viewing. We have more reservations about the gamma response. In the darkest parts of the image the TV runs it noticeably above the reference value, so some shadow detail can be a little too subdued. The characteristic then calms down and across much of the range it is close to the intended behaviour. As a result SDR generally looks natural, but in dark scenes the P7L can lose some subtlety.

In HDR the factory calibration is less precise. As brightness increases the excess of blue becomes more pronounced, which can make the image look cooler than it should. The number of larger colour deviations also grows, particularly in brighter hues. As for the EOTF curve itself, it is handled fairly conservatively, with the TV showing the image darker than the reference across much of the range. For such an inexpensive model, the factory Film mode settings are not bad.

The biggest beneficiary of calibration in the case of the Hisense E7Q / E79Q was undoubtedly the SDR mode. It managed to achieve an almost perfect image – most errors in the Color Checker test dropped below a value of 3, and often even 2, which is an outstanding result for this class of equipment. The greatest improvement came from equalising the brightness characteristic (gamma), which meant the image no longer appeared washed out and regained its natural depth. In HDR content, it was also possible to improve colours and eliminate the purple tint mentioned earlier, but errors in the Color Checker measurements were still noticeable. This is due to the fact that – as is often the case with Hisense televisions – the screen manipulates brightness quite heavily, overemphasising some colours. This was also indicated by the EOTF curve, which was slightly above the reference values, suggesting these minor issues with excessive brightness. Despite this drawback and the design limitations that emerge with HDR content, the Hisense E7Q / E79Q gained quite a lot after calibration. In everyday use, the television presents a consistent, natural, and pleasant image, and the difference compared to the factory settings is enormous.

After calibration the TCL P7L can deliver a genuinely pleasant picture, especially with conventional SDR material. We managed to even out the white balance very well, and the gamma curve now tracks close to the target value of 2.4. This is also reflected in the colour measurements: most errors have fallen noticeably, and in everyday viewing it is hard to point to any obvious inaccuracies. Films, series, YouTube and ordinary broadcast TV therefore look more natural, without unnecessary warmth or a cool tint. For a model in this price bracket the SDR performance is really very good.

With HDR the situation becomes more complicated. Calibration helped improve the white balance and tidy up some deviations, but here the panel's limitations become increasingly apparent. The P7L has relatively low brightness and cannot maintain adequate luminance for more saturated colours, so some errors remain even after careful tuning. In other words, settings can improve the way the TV interprets the signal, but they cannot overcome its physical limits. That is why calibration makes most sense for this model primarily in SDR.

In the case of the Hisense E7Q / E79Q, upscaling and digital image processing are not the strongest aspects of this television. It is evident that the manufacturer has opted more for simplicity rather than advanced image processing algorithms. The television does not offer any features to smooth tonal transitions or systems to improve image clarity, resulting in lower resolution materials looking simply very raw. On the screen, you can notice subtle compression edges that better processors in other models can effectively hide.

During the HD material tests, we noticed that the E7Q tries to artificially enhance detail, which sometimes works, and at other times has the opposite effect – the image becomes soft, slightly blurred, at times even “watery.” There is no aggressive sharpening that ruins naturalness, but there is also no finesse in the detail integration that better image converters offer.

In this respect the TCL P7L performs surprisingly well, especially for such an inexpensive TV. The banding-reduction feature, which in many budget models does little or nothing, actually manages to improve the picture here. It does not remove all banding entirely, but it can noticeably reduce posterisation and make more challenging gradients look more natural. At this price point that’s a genuinely pleasant surprise. Upscaling itself also performs well. Lower-resolution material is scaled correctly, without over-sharpening or adding artificial outlines around objects. Of course the P7L won’t turn a very poor source into a 4K-quality image, but for regular TV the result is simply solid. For a model in this class there is little to criticise.

Hisense E7Q / E79Q is a television with a 60 Hz screen, so fans of 4K sports may feel a slight disappointment – we simply won’t see such smooth images here as in more expensive models with higher refresh rates. Fortunately, the situation is much better for films. Cinematic materials recorded at 24 frames per second can be displayed here using a motion smoothing feature, allowing the user to tailor the picture to their own preferences – either more cinematic with visible frames or smoother, in a theatrical style.

The TCL P7L uses a panel with a native 60 Hz refresh rate at 4K resolution, and that's how it should be regarded in everyday use. When watching films the TV mainly offers frame interpolation, so it can smooth motion and reduce the characteristic judder, but it does not deliver the fluidity typical of true 120 Hz panels.

Hisense E7Q / E79Q is truly a successful television for gamers, even though it does not support 4K signal at 120 Hz. The manufacturer, however, has ensured a set of features that until recently could only be found in more expensive models. There is ALLM, meaning automatic switching to low latency mode, allowing the television to activate game mode with very low input lag by itself. We also have VRR, functioning up to 60 Hz – while this may not look impressive on paper, in practice it is fully sufficient, as most games on consoles do not exceed this limit. All these settings can be quickly found in the Game Bar panel, a convenient menu created specifically for gamers. From this interface, one can change picture modes, enable a frame counter, or even... an on-screen reticle – humorously named "target point" in the Vidaa system, which is a result of awkward translation from the Chinese manufacturer.

Special praise should be given to the ability to play in 1080p at 120 Hz, which significantly improves the fluidity and responsiveness of the image. Therefore, if someone wants to play a few titles at a higher refresh rate, they can simply lower the resolution and enjoy much smoother motion. Despite the lack of 4K@120Hz, the Hisense E7Q / E79Q performs really well as a gaming television – especially for those who are not looking for perfection but rather a solid and fast screen for everyday gaming.

For such an inexpensive TV, the P7L has quite a lot to offer gamers. It has ALLM, VRR, Dolby Vision for gaming, and TCL also includes its Game Bar, which lets you quickly check the key information or change some settings without leaving the game. Not everything is perfect, though, because HGiG doesn’t work here as it should, but at this price point it’s hard to complain about the feature set. The most interesting part starts when you give up 4K. At that resolution the TV runs at up to 60 Hz, but at 1440p and 1080p it can display at 120 Hz. And that’s not just a line in the specs. In fast-paced games that support that frame rate you can really notice the improvement in smoothness, so if you value smoother motion more than maximum image detail, that mode can make a lot of sense. Of course, that doesn’t turn the P7L into a proper 120 Hz TV. Even so, those extra modes are exactly what make the P7L perform very well for gaming.
