Presentation

The Hisense 55A7500F 4K TV features a 55-inch (≈140 cm) 10-bit VA (8-bit + FRC) panel displaying Ultra HD (3840 x 2160 px) definition. On this entry-level Ultra HD model, the refresh rate is unsurprisingly limited to 50 Hz. There is a simple DVB-T2 / C / S2 tuner (TNT, cable and satellite), a 2 x 10 W audio system , an MStar MSD6886 quad-core processor and the in-house VIDAA U4.0 operating system with a few popular apps including YouTube, Netflix, Amazon Prime, and even Molotov pending the arrival of MyCanal in the coming weeks.

In its 55-inch version, this television is sold for around € 600. It is also available in a 43 inch (109 cm), 50 inch (127 cm) and 65 inch (165 cm) version at the respective prices of around 450 €, 500 € and 800 €.

Image quality

The Hisense 55A7500F has a VA panel on board. This technology makes it possible to obtain good contrast, and therefore deeper blacks to the detriment of narrower viewing angles than those of IPS or Oled panels. On this TV, we measured a 70% loss of brightness at 45 ° to the sides. We can therefore largely perceive the variation of colors on the sides.
Colorimetery Delta E = 3.2
In Night Cinema mode, the Hisense 55A7500F television offers fairly accurate colors, even if they cannot be considered as perfectly faithful to those sent by the source. We measured an average delta E of 3.2, greater than 3 – the threshold above which the human eye can perceive the drift of a color. Overall, it is still very good.
GAMMA – 2.29

The gamma BT.1884 by default follows the profile of the reference curve with just a small hiccup on the very light grays, very slightly overexposed. The average gamma measured at 2.29 remains very good and the grayscale rendering is generally very good.

TEMPERATURE – 7100 K

The color temperature is fairly stable across the spectrum, but it is slightly too high. Indeed, the average measured at 7070 K is higher than the 6500 K reference of the video standard, but this has very little impact on the final image.

CONTRAST – 4040: 1
The 4040: 1 contrast ratio is very good for an LCD TV, especially in this price range. On this point, this Hisense television teases the best LCD models like the Samsung QE65Q80T or the Sony KD-65XH9505 . Obviously, it cannot compete with OLED televisions and their contrast considered to be infinite.

The scaling engine used by Hisense is very basic. It smooths the original source, which results in a slight loss of sharpness in the image. On this point, the Chinese manufacturer lags behind the best players in the market, including Sony, Philips and Panasonic. The TV does have a motion compensation engine, but it has no impact on the image. The moving image suffers from a fairly present blur, whatever the chosen mode.

HDR

The Hisense 55A7500F television is compatible with HDR10, HLG and more interesting signals with Dolby Vision. This dynamic metadata standard is particularly interesting on this type of entry-level television, the processing performance of which is limited.

LUM. MAX. : 360 CD / M²

 

 

 

 

 

 

 

 

 

 

 

 

With a maximum HDR signal at 10,000 cd / m², the Display Tone Mapping used by Hisense follows the reference curve fairly well (in yellow) before smoothing the signal from 55% luminance in order to limit clipping . Unfortunately, the peak brightness measured at 360 cd / m² is higher than what is usually found in this price range (around 300 cd / m²), but it remains in absolute terms quite limited to be able to benefit from a HDR picture worthy of the name. Fortunately, Dolby Vision compatibility makes it possible to enjoy HDR compatible content a little better, but the visual impact is still limited.

HDR COLORIMETRY
Delta E = 4.3

HDR Night mode offers the best color rendering. We measured the average delta E at 4.3. While the colors cannot therefore be considered perfect, they are average, especially for HDR on a TV in this price range.

REC. 2020 60%
DCI-P3 74%

 

The Hisense 55A7500F shows coverage of only 60% of Rec. 2020. It’s not much, but common to most entry-level and mid-range LCD TVs on the market. For the moment, the cinema is satisfied with the DCI-P3 color space, and the Hisense television set only 74% of this space. This is insufficient to make the most of the colors in this space. This TV is a far cry from the 90-95% of the P3 seen by Oled TVs and the best LCD TVs.

Video games

If this television shows a very good display delay with 15 ms, which translates into less than one image delay compared to the source and an imperceptible shift between the action on the joystick and its repercussion on the screen , it sins by a very high afterglow time, measured at 20 ms, which materializes as a trail behind moving objects. In comparison, the best LCD TVs display an afterglow time of only 11 ms like the Sony KD-55XH9096 or the Samsung QE65Q800T , while OLED televisions are untouchable with an afterglow time of less than 1 ms.

Hisense has the good idea to let the user activate Game Mode on any picture preset. It is therefore possible to reduce input lag while maintaining the color fidelity of Cinema Night mode. It is therefore clear on this particular criterion.

Clouding

The thermal signature shows that the Hisense 55A7500F television uses a Direct Led backlighting system

 

The use of a Direct Led backlighting system limits the risk of clouding , but this defect can still appear if the light distribution filter is damaged during transport. While we did not see a clouding problem  on the model we tested, we noted a significant drop in brightness in the corners. We were also able to see a slight banding on the homogeneous light gray backgrounds.

We measured the average difference in homogeneity of the white over the entire slab at 14%; an average figure for a 55 inch LCD television. Remember that below 20%, the eye does not perceive a difference in uniformity.

Comfort & design

The Hisense 55A7500F has a fairly classic design, but well finished. Plastic imitation aluminum is an illusion. The base of the slab also in imitation aluminum brings a little premium side.

This television adopts a rather bulky central foot which occupies a good part of the TV cabinet and does not facilitate the installation of a sound bar . Fortunately, its depth remains limited.

Review: Hisense 55A7500F 4K TV

At the back of each side of the foot, there is a fairly basic, but very effective cable management system. We would like to see this type of little detail more often on televisions in this price range.

The screen edges are quite thin for a 55 inch TV. The frame is pretty well adjusted, especially for an entry-level model. We did not note any assembly defect.

The panel of this Hisense television does not really filter glare. It does a bit better than other entry-level TVs like the Samsung RU7105 , but it can’t compete with the best on the market like OLED models or high-end QLED TVs.

Review: Hisense 55A7500F 4K TV

Without its feet, the Hisense 55A7500F displays a depth of 7.8 cm. However, the size of the TV cabinet remains linked to that of the foot, the depth of which is limited to only 25 cm. This television is therefore relatively comfortable on our reference cabinet which measures 160 x 40 cm.

The back of the TV is very simple. We find the power connector on the left, the connectors on the right and the VESA 200 x 300 mm mounting holes in the center.

Grouped at the back of the television, the connection consists of four HDMI 2.0 inputs, two USB ports, an Ethernet port, an optical digital audio output, a TNT / cable antenna socket and a satellite antenna socket. The TV also has Wi-Fi 802.11 a / b / g / n / ac and Bluetooth. On the other hand, it skips the headphone output.

Hisense’s Vidaa interface in version 4.0 is becoming more modern. It offers the basic functionalities of a connected TV, including popular applications such as Netflix, YouTube, DailyMotion, Rakuten TV, but also – it’s new for a few weeks – Molotov and soon MyCanal. The interface is generally smooth, which is a nice surprise for a TV in this price range. Hisense is still a step behind Android TV, Tizen and webOS, which now offer a more convincing experience, especially in terms of the number of applications and voice search, but the gap is narrowing more and more.

The first TV boot takes about 24 seconds, a faster time than Android TVs which boot in about 40 seconds, but far from Tizen or webOS which boot in under 10 seconds. The extinction is instantaneous while the recovery is done in less than 5 seconds; a great time, especially since the TV consumes less than a watt on standby.

Review: Hisense 55A7500F 4K TV

The remote control is light, it fits well in the hand and the rubber keys fall naturally under the thumb. The click after each press is audible. The remote control gives access to all the settings and even offers multimedia keys. Dedicated keys also allow direct access to Netflix, YouTube, Amazon Prime Video, Rakuten TV and the media player. The keys are not backlit, and especially the remote control does not embed a microphone, which does not allow to properly use the capabilities of this connected television.

Audio

Fairly classic, the audio system consists of two 10 W speakers. Unpretentious, it offers very average performance. The whole thing lacks bass, but, more annoyingly, the middle of the spectrum lacks clarity, which can be problematic for watching TV and correctly distinguishing voices.

Consumption

We measured the consumption at 65 W on our test chart with a blank set at around 150 cd / m². The relative consumption is only 77.9 W / m², which is lower than the average of the TVs tested (around 100 W / m²). This television does not do better than the Sony Bravia KD-55XG8505 – the least greedy of our comparison – with its 56 W / m² or even the Hisense 55U7QF with its 70 W / m². On this point, this Hisense television is still very good, consuming relatively little energy. In addition, standby consumption is always less than 1 W.

Our settings and measurements

To get the best picture rendering, we chose Night Cinema mode and then lowered the backlight to 32 in order to obtain a white around 150 cd / m². In the advanced settings, we then selected the ” Erased ” mode for motion compensation; it is the one that offers the best compromise. Below are the detailed results obtained with these settings:
Real contrast: 4040: 1
Black: 0.04 cd / m²
Gamma quality: 4/5
Delta E: 3.2
Slab homogeneity deviation: 14%
Viewing angles: 2.5 / 5
Consumption: 69 W

Hisense 55A7500F 4K TV – Conclusion

The Hisense 55A7500F is a good Ultra HD TV that offers a well-calibrated picture by default, a slightly higher peak brightness than models in the same price range and even benefits from Dolby Vision compatibility. You still have to make some concessions, especially in terms of responsiveness, sound or the absence of the microphone on the remote control. Finally, its most serious competitor is the Hisense 55U7QF (or its clone the 55U72QF ) which benefits from a greater peak in brightness and a microphone for an almost identical price thanks to repeated promotions.
