LG OLED G4 vs Hisense E7Q PRO / E79Q PRO

LG G4 guarantees an incredibly vibrant HDR effect, placing the television firmly at the top of the rankings. The highest model in the manufacturer's 2024 portfolio, equipped with the second generation of microlens technology (MLA), has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product of the Korean manufacturer may fall short compared to LCD televisions with Mini LED backlighting is during a full-screen scene featuring a lot of white. If we were to disregard the latter scene, the average result would be even higher. It's also worth mentioning scenes with very fine details, where each one shone at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 color space ensures that HDR materials are more engaging than ever before.

When it comes to HDR effect quality, the E7Q PRO unfortunately is not a television that impresses with brightness alone. In real film materials, we measured around 250–300 nits, which is simply not enough for HDR to look spectacular. There's a lack of that "spark" in bright details, flashes, and light effects, and in many HDR scenes, it can resemble more of a good SDR than true cinematic HDR. The silver lining in all this is the colours. We managed to confirm that the E7Q PRO is a PFS type television, which means it has an additional filter that improves colour gamut coverage. Because of this, even if the brightness doesn't deliver, the colours in HDR content can be properly saturated and pleasing to the eye, without the impression of a "washed-out" image.

The best factory mode in terms of colour reproduction was "Filmmaker". This is the one we used during our tests. Let's check how its characteristics looked before the calibration process. Taking a closer look at the white balance first, we can notice a significant dominance of red and green colour. As a result, the image had a warm yellow tint. This is the kind of characteristic we usually observe in "Cinema", "Filmmaker", or similarly named modes. The effect of such a colour balance was clearly visible in both SDR and HDR content, which, after switching from "Standard" mode, was distinctly yellowed. Now let's move on to two graphs that are responsible for brightness characteristics, and consequently, image contrast. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, the midtones and bright whites were represented very accurately, however, it noticeably lost the darkest details which blended into a black patch. On the other hand, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. There was also an issue with the colours themselves as seen on the "ColorChecker" graph since they were noticeably undersaturated.

In terms of colour reproduction, we tested the Hisense E7Q Pro in Movie mode, which undoubtedly turned out to be the best built-in preset. It is this mode, unlike the Eco, Standard, or Dynamic settings, that offers the most natural colours straight out of the box. While no factory mode is completely free of flaws, the E7Q Pro deserves high praise for its colour rendition in standard SDR content. The colour palette has been very well tuned, and errors in the Color Checker tests often did not exceed a value of 3, which is an outstanding result rarely seen in such affordable TVs. The only drawback we noted in SDR is the tendency to darken certain elements of the image, as indicated by a slightly raised gamma curve. The TV performs slightly worse with colours in HDR mode. Here, colour errors become noticeable to the naked eye, mainly due to a deficiency of blue in the white balance. This causes the colours on screen to appear too warm, and for some viewers, they may seem almost "too cinematic." Of course, to improve these parameters, we proceeded with professional calibration.

The manufacturer has been implementing extensive support for the calibration process in their LG televisions for many years. Therefore, we used 2- and 20-point grey scale adjustments along with an advanced CMS (Color Management System) and got to work. As you can see, thanks to the procedure carried out, each of the parameters has significantly improved. The use of tools has resulted in extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and proper colour saturation. Thus, we have maximised our approach to the reference image, or the one that the film director saw on the preview monitor. It is worth noting that the LG G4 televisions are the only ones that allow for even deeper intervention in image quality due to the capability to calibrate with 3D LUT matrices. However, this solution is recommended only for post-production or graphic studios.

In the case of materials with 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's worth noting that the E7Q Pro unit we tested happened to be exceptionally well-made from 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 adjustments. The biggest beneficiary of professional calibration was undoubtedly HDR mode. This is where we did the most work, which brought spectacular results. We successfully tamed the excessive warmth of the image, caused by a factory shortfall in blue colour. After calibration, colour errors were reduced to a significantly lower level, which will certainly please those watching a lot of streaming content in HDR format, expecting faithful reproduction.

The tested television did not perform well with content rich in tonal transitions, resulting in a strong posterisation effect. However, there is a partial remedy for this ailment. 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 high smoothing effectiveness on bright colours, though low on darker ones. We recommend primarily using the first one due to the fact that the other two interfere with directorial intentions, removing film grain.

When watching lower-quality content, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, attention should be paid to the jagged edges of fine details and minor issues around characters, such as the creation of a halo effect, which occurs due to the sharpening imposed by the LG G4 even when the slider is set to the lowest value, which is 0. It is worth noting that this is a change in relation 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 here and doesn't fall dramatically short of much more expensive, advanced TVs. Lower quality materials can look clear and reasonable, without the impression that the image is artificially "overdrawn." The smoothing function, however, presents a bit worse. Yes, it can be effective and improve tonal transitions in low-quality materials, but at the same time, it can introduce unwanted effects. Sometimes it removes film grain or adds unwanted artifacts, giving the image a more "digital" character. Therefore, we mainly recommend it to those who prefer a smoother, less cinematic image style.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible by connecting the LG G4 to a very powerful PC. Otherwise, we will be operating 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 who require high fluidity of image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It 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 increment affecting the degree of smoothing, so everyone can find their sweet spot.

The LG OLED G4 panel features an average response time of 0.78 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable by LCD televisions, which have response times of even several milliseconds. This is clearly visible in the "UFO Test" images, showing the absence of any trailing blur behind the object. Furthermore, the LG OLED G4 test showed that the television offers the ability to precisely adjust motion smoothing functionality, allowing users to choose the ideal level of image interpolation. We particularly appreciated this during fast-paced action in video games, where the LG G4 performed exceptionally well, minimising any blurriness. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sports or movie scenes.

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

The LG G4 television supports all features that make up the HDMI 2.1 standard. During testing, each feature activated without any issues, which allows us to consider the television as designed for gaming. Its performance will certainly be appreciated by both console users and those connecting the LG G4 to a computer. It’s also worth mentioning the proper implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels beyond the maximum luminance of the LG G4 will correctly map tones, keeping the game image true to the original.

A nice touch is the presence of a special GameBar that we can bring up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, turning on VRR technology does not degrade contrast, which is often a problem in televisions with local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emissiveness. As a journalistic note, we will only mention a slight grey flicker, which, however, is somewhat normal when VRR is enabled.

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

E7Q PRO is a phenomenal screen for gamers. Besides the typical "issue" with Hisense, which is the lack of support for the HGiG format due to constantly active tone mapping, we get practically everything one could expect from a TV that is supposed to have a gaming tag. There are two HDMI 2.1 ports, along with a full set of key features. We have variable refresh rate, automatic switching to game mode, and support for 4K at 120 Hz. On top of that, all the important settings are at hand in the clear Game Bar. This tool not only looks modern, but it also has a typically "gaming" edge and actually makes life easier while gaming.
