LG OLED G4 vs Hisense E7Q PRO / E79Q PRO

LG G4 guarantees an incredibly vivid HDR effect, placing the television among the very best. The equipment of the highest model in the producer's 2024 portfolio with the second generation of micro-lens technology (MLA) has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product from the Korean manufacturer may lag behind LCD televisions with Mini LED backlighting is during the full-screen scenes featuring a lot of white. If we disregard the latter type of scene, the average result would be even higher. It is also worth mentioning scenes with very fine details, where each one shines at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 palette makes HDR materials more engaging than ever before.

When it comes to the quality of the HDR effect, the E7Q PRO is unfortunately not a television that can impress with brightness alone. In real film materials, we measured around 250–300 nits, which is simply too little for HDR to look spectacular. There is a lack of that "spark" in bright details, highlights, and light effects, and in many HDR scenes, it can resemble good SDR more than true cinematic HDR. The consolation in all this is the colours. We managed to confirm that the E7Q PRO is a PFS-type television, meaning it has an additional filter that improves colour gamut coverage. As a result, even if the brightness does not deliver, the colours in HDR content can be appropriately saturated and pleasing to the eye, without the feeling of a "washed-out" image.

The best factory mode in terms of colour reproduction was "Filmmaker". This was the one we used during our tests. Let's check how its characteristics looked before the calibration process. Looking closely at the white balance first, we can notice a significant dominance of red and green. As a result, the image had a warm yellowish hue. Such characteristics are typically observed in "Cinema", "Filmmaker" or similarly named modes. The effect of this colour balance was clearly visible in both SDR and HDR content, which after switching from "Standard" mode appeared distinctly yellow. Now, let's move on to two graphs that are responsible for the brightness characteristics and consequently the contrast of the image. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, midtones and bright whites were reproduced very accurately; however, it noticeably lost the darkest details, which merged into a black blob. Conversely, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. The colours themselves also posed a problem, as can be seen on the "ColorChecker" graph, since they were noticeably under-saturated.

In terms of colour reproduction, we tested the Hisense E7Q Pro in Movie mode, which turned out to be the best built-in preset without a doubt. This mode, unlike the Eco, Standard or Dynamic settings, offers the most natural colours straight out of the box. Although no factory mode is completely free of flaws, the E7Q Pro deserves high praise for its colour rendering in standard SDR content. The colour palette is very well tuned here, and the errors in the Color Checker tests often did not exceed a value of 3, which is an outstanding result rarely seen in such affordable televisions. The only drawback we noted in SDR is the tendency to darken some elements of the image, as indicated by the slightly raised gamma graph. The television performs slightly worse with colours in HDR mode. Here, colour errors become noticeable to the naked eye, mainly due to a lack of blue in the white balance. This causes the colours on the screen to be too warm, and for some viewers, they may even seem “too cinematic.” Of course, to improve these parameters, we proceeded with professional calibration.

The manufacturer has implemented extensive support for the calibration process in its LG televisions for many years. We therefore used 2- and 20-point greyscale adjustments, as well as an advanced CMS (Colour Management System), and got to work. As you can see, thanks to the procedure carried out, each parameter has significantly improved. The use of tools allowed for the achievement of extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and suitable colour saturation. This brings us as close as possible to the reference image, which is what the film director saw on the preview monitor. It is worth noting that the LG G4 televisions alone allow for even deeper intervention in image quality thanks to the ability to calibrate with 3D LUTs. However, this is a solution recommended only for post-production or graphic studios.

In the case of materials with a standard dynamic range (SDR), our actions in Filmmaker mode turned out to be largely cosmetic 😉. We mainly focused on a subtle adjustment of the white balance and equalising the gamma curve, which allowed us to recover details in the darker areas of the image that previously tended to get lost. However, it is worth noting that the E7Q Pro unit we tested was exceptionally well-made at the factory. We remind you that these parameters depend on the specific unit – with mass production, factory calibration can be random, so your unit may require slightly different intervention. The biggest beneficiary of professional calibration was undoubtedly HDR mode. This is where we did the most work, which brought spectacular results. We managed to effectively tame the excessive warmth of the image, caused by a factory deficiency in blue colour. After calibration, the colour errors were reduced to a significantly lower level, which will certainly please those who watch a lot of streaming content in HDR format, expecting faithful reproduction.

The tested television did not perform particularly well with materials rich in tonal transitions, as a result of which we could observe a strong posterisation effect. However, there is a partial remedy for this issue. The manufacturer has equipped the LG G4 with a smoothing system called "Gentle Gradation," which we can apply at three levels: Low, Medium, and High. Each of these options guarantees quite a high effectiveness of smoothing on light colours, although it is low on darker ones. We recommend primarily using the first one, as the other two interfere with the director's intentions by removing film grain.

When watching lower-quality materials, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, one should pay attention to the jagged edges of fine details and minor issues around characters, such as the creation of halo effects, which occurs due to the sharpening imposed by LG G4 even when the lowest value on the slider, that is 0, is set. It is worth noting that this represents a certain change compared to the LG G3, which did not impose such strong image sharpening, even when the appropriate slider was set to position 0.

When it comes to upscaling and digital image processing, the E7Q PRO deserves praise. The scaling performs really well and does not dramatically fall behind much more expensive, advanced televisions. Lower-quality materials can look clean and sensible, without the impression that the image is artificially "enhanced." However, the smoothing function presents a bit worse. Indeed, it can be effective and improve tonal transitions in poor quality materials, but at the same time, it can introduce undesirable effects. It sometimes removes grain or adds unwanted artefacts, giving the image a more "digital" character. Therefore, we mainly recommend it to those who prefer a smoother, less cinematic style of image.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible when the LG G4 is connected to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with high motion dynamics. For those requiring high image fluidity, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". This has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range from 0 to 10, with each level affecting the degree of smoothness, allowing everyone to find their golden mean.

The LG OLED G4 panel features an average response time of 0.78 ms (as directly derived from our measurements), enabling an incredibly clear image, unattainable by LCD televisions, which can have response times of several milliseconds. This is perfectly illustrated by the images from the "UFO Test", which show no trailing blur behind the object. Moreover, the LG OLED G4 test revealed that the television offers the ability to precisely adjust the motion smoothing function, allowing users to select the ideal level of image interpolation. We particularly appreciated this during fast-paced actions in video games, where the LG G4 performed exceptionally well, minimising any blurring. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sporting or cinematic scenes.

In the category of smearing and motion fluidity, the E7Q PRO has one very strong argument. At this price, Hisense has included a 120 Hz panel, and in PC mode, it can even operate at 144 Hz. This immediately provides greater possibilities in motion settings, as the menu offers more options for smoothing the image. Among other things, we have frame interpolation options, which allow us to adjust the fluidity for sports or films, depending on whether we prefer a more cinematic character or a "theatrical" smoothness.

The LG G4 television supports all the features that make up the HDMI 2.1 standard. During testing, each of them activated without the slightest problem, which allows us to consider the television as designed for gaming. Their functionality will surely be appreciated by both console users and those connecting the LG G4 to a computer. It is also worth mentioning the correct implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels exceeding the maximum luminance of the LG G4 will correctly map tones, and the game's visuals will remain true to the original.

A nice touch is the existence of a special GameBar, which we can call up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, enabling VRR technology does not degrade contrast, which is very common in televisions that feature local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emission. As a matter of editorial obligation, we will only mention a slight grey flicker, which is somewhat normal after enabling VRR.

In summary, the LG G4, like practically all OLED televisions, is an ideal product for all kinds of games and online competitions. With fully-fledged HDMI 2.1 connections with a full bandwidth of 48 Gbit, features such as VRR, ALLM, G-Sync, FreeSync, or gaming in HDR Dolby Vision will bring much joy.

The E7Q PRO is a phenomenal screen for gamers. Aside from the typical "ache" of Hisense, which is the lack of support for the HGiG format due to permanently active tone mapping, we get practically everything one can expect from a television that is to have a gaming label. There are two HDMI 2.1 ports, along with a full set of key features. We have variable refresh rates, automatic switching to game mode, and support for 4K at 120 Hz. Additionally, all the most important settings are at hand in a clear Game Bar. This tool not only looks modern but also has a typically "gaming" edge and truly makes life easier while gaming.
