Sharp GP6765 vs LG MRGB85B

In movie mode, the Sharp GP6765 reaches a brightness of 300 nits, which is relatively average. This level of brightness is more suited to standard SDR content than to the full HDR experience. As a result, the TV struggles to deliver the depth and dynamics typically expected from a good HDR mode. Visual effects that might appear sharp and detailed on other models could seem more subdued here, and high-contrast scenes won't be as striking. However, compared to other models in this price range, this is still a decent performance. A positive feature is the TV's support for a wide DCI-P3 colour gamut, covering 92.5%, thanks to the inclusion of quantum dots (Quantum Dot/QLED). This offers a solid improvement, particularly in this price bracket, resulting in vibrant and more saturated colours, although the limited brightness still prevents a fully immersive HDR experience.

LG MRGB85 offers moderate brightness. On test patterns it reaches about 700 nits, which by itself is a decent result. In actual movie scenes the values are lower and most often fall between 400 and 600 nits. Bright, expansive shots perform best. In scenes with a lot of black the TV noticeably limits luminance, trying to maintain the highest possible contrast. The HDR effect is therefore visible, but it is far from the level offered by more advanced Mini-LED designs. Especially in darker parts of films the limitations of edge-lit backlighting and imprecise local dimming become noticeable again.

HDR Colors

A much stronger suit of the MRGB85 is its colors. The TV covers about 95% of the DCI-P3 color space and 74% of BT.2020, allowing HDR material to look vivid and striking. Colors are well saturated, and the difference compared with basic LCD TVs is clearly visible. It is worth noting, however, that this is not a classic RGB backlight, where each of the three primary colors is generated by a separate diode. Red is produced by a PFS phosphor, which expands the palette and yields more saturated red shades. This solution works well for color reproduction, but it does not change the limitations of dimming itself. The LEDs are not driven independently in the way the series name might suggest... so it turns out that Mini RGB is not the same as Mini-LED RGB!

The Sharp GP6765 was launched in movie mode, which offers the best settings for colour reproduction. However, despite this, the quality remains far from ideal. In SDR mode, the white balance graph shows significant increases in the red colour, making the image appear somewhat yellowish and distorting natural skin tones. This results in some scenes looking unnatural, and colours losing their authenticity. In HDR mode, the issue worsens as blue becomes the dominant colour, which negatively affects the colour balance and causes a loss of detail in cool tones. As a result, the image can appear cold and unbalanced, highlighting the TV's inability to achieve optimal colour reproduction. Tests with the Colour Checker tool confirm these shifts across several samples.

In terms of contrast, the HD mode shows a significant jump at the start of the graph, but it remains close to the reference line at 2.4. This means that in most scenes, the TV delivers a satisfactory level of contrast, enhancing details in shadows and adding depth to the image. However, in HDR mode, the EOTF curve fluctuates significantly at both ends of the graph, leading to inconsistencies in bright and dark areas of the image. In scenes with intense light, such as explosions or dynamic actions, key details may be lost, and the image may appear blurry. Similarly, in darker scenes, the lack of clear differences in shades may cause details to merge into a uniform spot, reducing overall quality. While movie mode offers the best factory settings for the GP6765, there are still significant issues with colour reproduction and contrast.

We tested the TV in Filmmaker Mode, because among the available settings it produced the image closest to the reference. Factory color reproduction was not perfect. The biggest deviations were in the white balance, with too much red and not enough blue, which pushed the picture noticeably toward warmer tones. Whites took on a slightly yellowish cast, and skin tones and bright areas did not always look natural. It wasn’t a flaw that completely ruined the viewing experience, but in a direct comparison with the same screen after calibration the difference was clearly visible.

After calibration, the Sharp GP6765 television shows marked improvement in film mode, particularly in SDR content. The white balance now closely aligns with the reference line, offering more natural and true-to-life colour reproduction. While not perfectly straight, the results are still satisfactory for the price range, significantly enhancing the overall visual experience and immersion in movies. The colour gamut shows some improvement, with the initial jump in the graph persisting but being less noticeable, leading to a more consistent and enjoyable image.

For HDR content, while the white balance performs somewhat worse than in SDR, it is still a notable improvement compared to pre-calibration. The calibration ensures better colour consistency, though some shortcomings remain. As for contrast, no major gains were observed. The lack of control over dynamic tone mapping prevented significant improvement in EOTF, resulting in uneven brightness reproduction.

Despite some limitations, particularly in HDR content and dynamic tone mapping, the Sharp GP6765 reveals a more polished performance after calibration. The improved white balance and colour reproduction in SDR make it more visually appealing. While further refinement is needed, it still provides a satisfying visual experience, making it a strong contender in its price category.

Calibration primarily corrected the white balance and removed the previously visible warm tint. After the adjustment, whites no longer had a yellow cast and colors became more neutral and natural. The biggest improvement was seen in SDR content, where the picture looked even and much closer to the reference. A similar effect was achieved in HDR. After calibration the picture became more controlled, although not all of the TV's limitations could be eliminated. The biggest issue remained the intense reds, which were not always reproduced with the necessary precision. In practice the MRGB85 handles everyday SDR content very well, but in more demanding HDR material its limitations remain clearly visible.

The Sharp GP6765 television delivers solid performance with its "10-bit colour reproduction" feature, particularly in the tested scene featuring light bulbs. Setting this option to "medium" provides satisfactory results, with no issues related to grain smoothing or the blurring of important image elements. Even the "low" setting performs well, delivering a clear image without compromising detail. These transition smoothing options enhance visual quality by providing more natural colour transitions.

In terms of image scaling, the Sharp GP6765 shows strengths, such as the absence of overscan when displaying test material. This ensures viewers can enjoy the full image without losing edge details. However, some weaknesses were noted in a tested scene featuring a model. Elements such as branches or trousers appear slightly jagged, indicating a lack of effective edge-smoothing techniques. This can cause certain details to look distorted, impacting the overall viewing experience.

Upscaling and digital image processing perform quite well on the LG MRGB85. The Alpha 8 AI 4K Gen7 processor efficiently upscales lower-resolution content, and you can easily disable overscan regardless of the source. The TV also handles compression artifacts fairly well. The "Smooth Gradation" feature can effectively reduce visible banding and tonal unevenness, but it doesn't always work precisely. At higher settings it can smooth over fine details, for example material textures. On the plus side, it doesn't remove film grain. It's safest to use the "Low" or "Medium" setting, which provides the best compromise between artifact reduction and detail retention.

When it comes to motion blur and movement fluidity, the Sharp GP6765 TV offers rather average performance. Equipped with a 60 Hz panel, it handles movies adequately. The TV includes a motion smoother called "Motion Enhancement," which allows users to control motion fluidity, enabling a choice between visible film frame interpolation or a smoother, more theatrical appearance. This feature should meet the needs of most users focused on movie viewing.

However, the TV's performance falls short in sports or gaming. In the tested UFO alien scene, noticeable blurriness indicates that the panel's low response time negatively impacts the sharpness of moving objects. This issue becomes particularly evident during dynamic sequences, where rapid movements are frequent. For viewers who enjoy sports or fast-paced video games, these limitations in motion handling can be off-putting, making the Sharp GP6765 less suitable for such content.

The LG MRGB85 is equipped with a VA panel with a native 144 Hz refresh rate, so it performs very well in terms of motion smoothness. The TV easily handles 120 Hz content from consoles and higher refresh rates when connected to a PC. That matters not only for gaming but also when watching sports, where camera movement is noticeably smoother than on basic 60 Hz models. There's also the TruMotion system, which lets you set the level of motion smoothing yourself. You can keep a more cinematic motion or increase smoothness, which works well for sports broadcasts and TV shows. The range of adjustment is wide, so you can easily tailor the motion smoothing to your preferences.

The gaming functionality of the Sharp GP6765 leaves much to be desired. Although this model includes HDMI 2.1 ports, which theoretically promise modern features, the reality is far less impressive. The only feature that takes advantage of this standard is Auto Low Latency Mode (ALLM). Unfortunately, the absence of key functionalities such as Variable Refresh Rate (VRR) and HDR Gaming Interest Group (HGIG) significantly limits its appeal to gamers. VRR is crucial for eliminating screen tearing and stuttering, particularly in dynamic games where fluidity is essential. Similarly, HGIG ensures optimal HDR mapping, enhancing visual quality and immersion. While Dolby Vision might seem like a benefit, it proves useless for gaming due to the very high input lag in this mode.

The inclusion of HDMI 2.1 ports in the Sharp GP6765 feels like a marketing ploy, potentially misleading users into believing that the standard automatically provides all its associated benefits. Gamers expecting full functionality from HDMI 2.1 are likely to be disappointed.

When it comes to gaming, the LG MRGB85 performs best by far. The manufacturer didn’t skimp on the feature set and essentially brought the full suite of functions from higher-end TVs to this model. You get three HDMI 2.1 ports with full 48 Gbps bandwidth. Each of them supports 4K 120 Hz from consoles, and when connected to a PC also 4K 144 Hz. So you don’t have to worry about which port to plug your console or PC into, since they all offer the same capabilities.

It also includes VRR, AMD FreeSync Premium, NVIDIA G-Sync Compatible, ALLM, and HGiG. Dolby Vision Gaming is present as well, allowing supported games to use high refresh rates and dynamic HDR simultaneously on Xbox. Rounding it out is Game Optimizer, a handy in-game menu for gamers. Without leaving the game you can change the picture profile, brighten shadow details, or check the current frame rate. In terms of gaming features, the MRGB85 therefore offers almost the same as much more expensive LG models.
