Sharp GP6765 vs Philips OLED811

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.

Philips OLED811 uses the new generation WOLED EX panels, also found in models like the LG C6 and Samsung S90H. After calibration we measured around 1500 nits, which is a very good result for an OLED TV. You can see it clearly in movies and series. All kinds of light flashes have the right intensity, especially when they appear on a dark background. In such scenes the OLED811 can deliver truly impressive HDR. Of course, that doesn't mean you'll see that peak brightness in every shot. When the screen is filled with a large area of white or a big explosion, brightness falls to around 600 nits. That's still a good result, but those scenes no longer have the same punch as small, bright elements on a dark background. This is a known limitation of OLEDs, and the OLED811 is no exception.

Colors

Aside from HDR brightness, colors also matter, and Philips performs very well here too. It covers almost the entire DCI-P3 gamut, which contains most of the colors used in HDR movies and series. So you get rich reds and lush greens, and while watching it's hard to find major faults in this area. It looks a bit worse with the much wider BT.2020 gamut — its most saturated shades are already beyond the reach of this panel. Added to that is the issue of the white subpixel the WOLED panel uses to help boost brightness. With very bright colors you can see some "whitening": the color is bright but loses some of its saturation. In exactly these situations QD-OLED panels from Samsung Display have the advantage. In most movies and series, however, this won't be something that immediately stands out.

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.

The movie mode on the Philips OLED811 is sensibly configured right out of the box. Most color errors are minor, both in SDR and HDR, so you can sit down and watch without first adjusting the settings. There are no major inaccuracies that would immediately pull attention away from the film.

It's not perfect, though. The white balance shows a slight deficiency of red compared with green, so whites and grays can have a faint greenish tint. It's not a strong cast, but measurements clearly show it. There are also small brightness deviations in SDR: some areas of the picture are slightly lifted, and the deepest blacks aren't always rendered evenly. In HDR the TV tracks the reference much more closely, although in places it slightly pulls details out of the shadows. These are generally things to refine. The factory movie mode provides a good starting point, and calibration will show how much more you can get out of it.

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.

After calibration the Philips OLED811 produces an image very close to the reference. We managed to even out the white balance and remove the subtle color cast visible in the factory settings. Errors in Color Checker measurements for SDR and HDR dropped to around 1 to 2, and many samples even fall below 1. That's a level at which it's hard to spot differences from the reference image with the naked eye. We also improved the gamma, and only in the brightest whites a slight brightening remains. In HDR the EOTF curve also stays close to the reference, although the TV still tends to slightly boost the brightness of small elements like stars or subtitles. That gives the image a bit of extra glow that shouldn't be there, but otherwise there's little to complain about. It was already good out of the box, and after calibration we managed to refine most of the remaining shortcomings.

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.

The OLED811 handles lower-quality content reasonably well, though it's far from perfect. The "Artifact Reduction" feature helps smooth tonal transitions and on the low setting delivers a pretty good result. It doesn't remove banding between shades as effectively as similar solutions from some competitors, but at least it doesn't introduce new artifacts. That's a sensible setting for everyday viewing. Still, there's some disappointment, because the MediaTek Pentonic 800 chip used here can, in other manufacturers' implementations, deal more effectively with heavy compression even at similarly low settings. A lot therefore depends on how each manufacturer uses its capabilities. We have a few more reservations about the 4K upscaling itself. There is plenty of detail, but the overall image looks fairly soft. Edges are heavily smoothed, which robs the picture of some sharpness and clarity. You can partly correct that with the sharpness slider in the menu, though that will just emphasize outlines rather than recover detail. On the plus side, there is no overscan, so even with an SD signal the TV does not crop the edges of the picture.

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.

In terms of motion handling, the OLED811 performs excellently. At 120 Hz, which is useful for console gaming and watching sports, the image stays clear and moving objects don’t leave noticeable trails. The fast response of OLED pixels helps here; you can see it clearly in the UFO test, even on dark backgrounds. There are also motion-smoothing controls. For movies you can adjust the strength of smoothing to your taste, ranging from preserving a cinematic feel to much smoother motion. A separate motion blur reduction control is useful for fast-paced content like live sports broadcasts.

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.

OLED811 has almost everything you could expect from a gaming TV. It supports 120 Hz at Full HD, 1440p and 4K resolutions, and when connected to a PC can reach 165 Hz. It also has VRR, which helps avoid screen tearing with variable frame rates, and ALLM, which automatically switches to game mode. So you don't have to dig into the settings every time you power up your console.

HGiG also works correctly, so once you enable HDR on the console the TV doesn't apply its own brightness adjustments. There's also a Game Bar that lets you check signal parameters and quickly change settings useful while gaming. The list even includes Dolby Vision for games, but there's a significant catch, which you'll read about below.
