The television TCL MQLED85/C765 was tested in movie mode, which, although it seems to be the best setting from the manufacturer, is not without flaws. The colour reproduction in HD/SDR mode MQLED85 shows some shortcomings. In the analysis of white balance, there is a significant lack of blue, which can affect the overall image quality, especially in bright scenes where blue shades are crucial for natural representation. The overall shape of the image may then appear too warm. Regarding gamma contrast, the graph shows a large jump above the reference line of 2.4 at the beginning, which may suggest significant dimming of brightness in darker areas, leading to loss of detail in black. Then, for most of the time, the values lie below this line, which may lead to loss of detail in brighter parts of the image. Such a distribution can negatively impact perceived image quality, particularly when watching regular television in HD quality.
In the case of 4K HDR image quality of the TCL MQLED85/C765, there is a noticeable excess of red in the analysis of white balance. This excess can significantly affect the viewer's experience, leading to several significant effects. Firstly, an excessive amount of red can make other colours, such as green or blue, appear muted or unnatural. This distortion of colour balance can result in an overall impression of "over-saturation," which detracts from the naturalness and authenticity of the image. As for contrast, the EOTF (Electro-Optical Transfer Function) graph indicates that most values are above the reference line, suggesting an intense boost in brightness in bright areas of the image. However, there is an exception at the beginning of the graph, where the EOTF line is below the reference line, which can lead to excessive dimming of small light elements.
Users should be aware that despite using the best mode, which is movie mode, the television is not free from flaws in terms of image settings, so it is worth considering adjusting the settings to achieve better results.
Sharp GP6765 was launched in movie mode, which is the best setting for colour reproduction. Unfortunately, despite this, the quality still falls short of ideal standards. Starting with white balance, in SDR mode, the graph shows significant increases in the case of the red colour. This effect can make the image appear slightly yellowed, leading to distortion of natural skin tones. As a result, viewers may notice that some scenes seem unnatural, and colours lose their authenticity. In HDR mode, the situation changes dramatically – the dominant colour becomes blue. Such a strong shift towards blue also negatively affects the colour balance of the image, which can lead to loss of detail in cool tones. Viewers may feel that the image is somewhat cold and out of balance, which further emphasises the fact that the television does not achieve optimal colour reproduction. Tests carried out using the Colour Checker tool confirm these shifts in several tested samples.
As for contrast, in HD mode, the range shows a significant jump at the beginning of the graph, but then remains close to the reference line at 2.4. This means that in most scenes, the television is able to deliver a satisfactory level of contrast. For the viewer, this translates into better perception of details in shadows and greater depth of the image, which affects their overall experience when watching films and TV programmes. In HDR mode, however, the EOTF curve displays large fluctuations both at the beginning and at the end of the graph. Such fluctuations can lead to inconsistencies in the reproduction of details in bright and dark areas of the image. For the viewer, this means that in scenes with intense light, such as explosions or dynamic actions, crucial details may disappear, and the image can appear blurred. Conversely, in darker parts of the image, the lack of clear differences in shades can cause details to merge into a uniform blob, significantly reducing the quality of viewing. Although movie mode offers the best factory settings in the GP6765, both in terms of colour reproduction and contrast, it still has significant issues.
