Why are the parameters of the smart TV purchase network different from the official publicity?

When many users compare the parameters of smart TVs, they often find that there are discrepancies between the parameters on our website and the officially published data, which raises some questions. However, I would like to emphasize that not all officially published information is accurate. Below, I will explain the reasons for these differences.

First, the difference in refresh rates.

The official advertisement may claim that the TV has a refresh rate of 120/240/288Hz, while our website lists a refresh rate of 60/120/144Hz. Does this mean that our data is wrong?

Starting in 2022, BOE and CSOT began to adopt HSR/DLG technology, which can double the refresh rate of the screen, but at the cost of reduced clarity. The main purpose of this technology is to make the data of the product look better, but in reality, its effect is not accepted by consumers. So, this feature doesn't really really do much use. Moreover, official advertisements often do not explicitly state "reduced clarity", which violates consumers' right to know. Our website lists the TV's native screen refresh rate, with HSR/DLG technology and multiplier refresh rate, and we also provide a detailed explanation of the features.

Secondly, the difference in color gamut.

In order to make your TV's color gamut value look larger, official advertisements usually mark the area of the field instead of the color gamut coverage, or mark it "lab theory". For example, phosphor wide gamut solutions typically achieve 92% DCI P3 coverage, but an advertisement might indicate a 130% BT.709 gamut area so that the numbers appear larger. For consumers who don't understand color gamut standards, they may only focus on the numerical values and ignore the units. Needless to say, the question of the theoretical value of the laboratory is not to be said.

The DCI-P3 color gamut coverage is also divided into CIE1931XY and CIE1976UV standards. For example, color gamut tests on RTINGS will label the values of the two criteria separately. You will find that the value of the XY standard is smaller than the value of the UV standard, so domestic manufacturers will choose to mark the UV value so that the value looks larger.

Third, the difference in brightness.

The brightness marked by BOE is a range, or the customer service sometimes gives "average brightness", which is of little reference significance, and this kind of error is very common. Our website is marked with "Peak Brightness", which is based on measurements from manufacturers, self-tests, and other media.

Fourth, the difference in the number of HDMI 2.1 ports.

Since HDMI called HDMI with 18Gb bandwidth HDMI as HDMI2.1, the problem of false standard of HDMI ports has become very serious in China. Our website recognizes that only those with a bandwidth of more than 40Gb are called HDMI 2.1, and those below are labeled as HDMI 2.0, and we clearly mark the bandwidth to ensure that consumers can understand it correctly.

Examples of false labels in official advertisements include:

Regardless of bandwidth, all ports are directly marked as HDMI2.1.

Even TVs with a native refresh rate of 60Hz will be marked as HDMI 2.1.

Finally, the difference in image quality chips.

Official advertisements may state that TVs have a separate picture quality chip, while our website may indicate that they do not have one.

Regarding this issue, in fact, only a few companies have independent image quality chips, and other companies refer to SOC as image quality chips. Even Sony is not completely immune to this problem, such as their x85 series, although they do not have a separate image quality chip, they also refer to the SOC as the X1 image quality chip. In this matter, you can directly refer to our website.
