The existing basic interface is also very rich, with 2 sets of HDMI2.0, a USB3.0+USB2.0, and coaxial output, ensuring the transmission of high-definition lossless audio quality, while other commonly used interfaces are also Should be complete. The replaceable box is a very good design, to know the life of the screen at least 5-8 years, and CPU, GPU upgrade is much faster, and replace the box upgrade hardware is the simplest and most cost-effective way to upgrade.

The remote control design follows the style of cool open white, with a more stylish and refined appearance, the use of environmentally friendly materials of advanced ABS resin, excellent grip, weigh your hands more. This remote control supports low-power Bluetooth connectivity and also supports infrared remote control.

Summary: From the appearance we can see that the cool open T55 conveys a new attitude of integrating into the fashion, and the unconventional flax character runs through. Highly customizable modules allow TV to be a plaything in the hand, and the addition of full touch makes TV a good helper for work and play.

PPTV-55T design adds a very narrow border design elements, only the border width of 5.8mm refresh the new record of the smart TV frame record, another advantage of the very narrow border is to bring a wider and wider visual field effect, giving a kind of no No bound feelings of the border.

At the same time, the "Bauhaus" design concept was added to abandon the bumpy structure on the side of traditional TV due to hardware reasons. The wedge-shaped and fully symmetrical design was used for packaging, and the side view was more of a design aesthetic.

After the shell design is also very particular about the rear shell using high-strength, high polymer material HIPS material, making the backplane design tends to be smooth, clean, in addition to the button design and the necessary interface, there is also a USB interface at the top of the fuselage, easy to use Connect cameras and other devices.

Regardless of the overall or details, PPTV-55T is very particular about the metal frame by anodized aluminum sandblasting process, and CNC diamond cutting process. Brushed texture of the metal plate surface, the overall texture is stronger, with a very high value.

Unique breathing lamp design and logo integration give people a sense of beauty. At the same time, it uses a unique unique tripod structure design that can be connected to its Sound-Bar stereo.

The PConline evaluation room used professional instruments to conduct detailed tests. Before the test, we first adjusted the TV display to the standard image mode. Other parameters were the default. The product was tested and scored in five aspects, and a five-dimensional performance chart was made. ,As shown in FIG.

From the perspective of the color transition, the color transition is also very harmonious and natural. From the pixel point of view, cool open T55 is indeed used by LG IPS hard screen, which matches the information provided by the official website, through color analysis equipment testing, measured red, green, blue three color coordinates converted The color gamut value reached 77.11% NTSC, which is the middle-to-upper level in the same product. Of course, the performance of the color gamut is not the only criterion for judging the quality of the screen. The degree of color reduction, light control performance, and dynamic performance are all important factors affecting the screen.

From the original data test point of view, cool open T55 for the optical three primary colors are very high degree of reduction, from the color space map we can see that the performance of red, green and blue are all approaching the edge of the limit; brightness and cool open T55 The BEF double brightness enhancement film is added to the backlight film to gather the scattered light, so that the brightness of the screen is greatly improved, and the uniformity performance is also very stable.

In the silk standard test screen, cool open T55's color reproduction ability is very good, the color performance is very realistic and look; color gradient and over-natural, the same shade of different shades of color can be well separated.

In the standard test of the yarn ball, it is mainly the presence or absence of a bond area between the yarn balls during the observation period. From the figure, the color reproduction between the yarn balls is accurate, there is almost no interference, and no stickiness occurs. The overall performance is very high. Baton!

The expression of people's skin color is also quite capable of embodying TV's ability to express colors. The yellow and white people holding a three-colored rose have very good color reproduction and rose color reproduction. The three-colored roses are colorful and the entire screen does not appear reddish or Whitening phenomenon.

Summary: Cool open T55 in terms of color performance so that I was very pleasantly surprised, although the color gamut obtained by the instrument test is not very high, but its performance in color reproduction and accuracy is very good, the color processing is also very pleasing The eye's preferences, in general, the performance of the color of the lever drops!

色彩 Color Test (II): PPTV-55T

The evaluation room uses professional instruments to conduct detailed tests. In the test, the author first adjusts the TV to the standard image mode, the backlight is adjusted to the brightest, other parameters are default, and the product is tested and scored in detail in five aspects. As a result, we do The five-dimensional performance chart is shown above.

Evaluation results as shown above, in the color adjustment, micro whale 4K smart TV color gamut as high as 88.39%, high color gamut performance undoubtedly derived from its use of LG original IPS hard screen. In terms of brightness, because 4K panels will reduce the panel transmittance, some manufacturers will use RGBW four-color pseudo 4K panels to increase the panel transmittance, micro whale TV does not do so, and the average brightness has reached a considerable 314.89cd/ M2.

In the brightness test session, the TV backlight setting needs to be adjusted to the highest, and other settings are the default. CANTV Super TV F55 average brightness of up to 278.67cd/m2, the performance of the white screen is very colorful, detailed description of the details of the screen does not say that the difference between the white under different gray values ​​is obvious, the screen of the object's dark side of the performance is also very To force, the entire screen has a strong sense of hierarchy.

For the average user, you can directly see the quality of the TV panel calibration through the black screen. When the surrounding environment is completely black, when the TV screen is turned to black, you can directly see the degree of light leakage. This is also the most direct judgment TV panel. Excellent calibration, all black case, CANTV Super TV F55 light leakage phenomenon is not obvious, there is a little white in the lower right corner, but the overall very uniform. In fact, light leakage is an inevitable phenomenon for all LCD TVs, but light leakage will not affect the quality and life of LCD TVs.

In terms of grayscale performance, due to the camera exposure, the effect of the photo display is not very obvious. In the black part, the boundary between 0~1th order and 14~15 is slightly blurred, and other parts are clearly visible to the naked eye.

The black and white background of the standard test disc, the two women's satin evening dresses stand on the same color background, the outline of the clothes of the clothes can be distinguished from the background color, and will not be integrated with its background; Tokyo Tower part, sky There was no light leakage, and there was a clear gap between the billboards. The charcoal part was mainly to see if the side lines were preserved. From the test screen, the black sinks down and still retains the details.

Summary: Under normal circumstances, the RGB 4K screen pixel density will increase the brightness of the picture will be reduced, but from the test point of view, CANTV Super TV F55 brightness value is still maintained at 278cd/m2, the latter screen calibration is quite strong, although there is a slight light leakage and Evenly, the dark part of the black part of the picture sinks down, while the details are not lost. The entire picture is full of layers. The following dynamic test, the high-speed motion picture, how to retain the details?

Brightness test We adjusted the backlight to the brightest, but the brightness value uses the default, and this brightness looks more natural. The brightness parameter of the screen is not the decisive parameter of the picture quality of the TV. Even if the brightness of the screen is low, due to the problem of the factory setting of the panel, products with low average luminance but excellent final picture quality are not uncommon. Seeing the white screen of Stormwind TV is very good and the picture is clear and detailed.

From the grayscale graph, we can see that the difference in the black part between 0-2 steps is not particularly high, and the differentiation in the white part 14-15 is not particularly high, and the details of the black screen may be affected.

Under the full black screen, the light leakage of the Superstorm TV is not serious, and there is no particularly significant light leakage.

In the black and white standard test screen, we can see that the Super White TV screen is very good, but the black screen is slightly weaker. In the charcoal part, there was no whitening phenomenon on the screen, but the details on the dark side were more difficult to identify; in the Tokyo Tower, the darkness of the middle billboard was more ambiguous, the sky went dark, and the bright part did not appear; In the dress lady test screen, the details of Ms. White's dress are not mixed with the background, and the degree of distinction is ideal, but there is a case in which the black lady can not distinguish from the background.

Summary: In the light control section, the performance of the Superstorm TV is inevitably somewhat regrettable. In particular, the gray-scale part does perform well in general, but it does not hide its influence. The performance of the white part is still very good, and most of the details can be characterized. The overall picture performance and all black leakage, the author also gave it a score of 7.5 points.

The test link through the enlarged view, through the train window to see the scenery on the other side of the train is clear to determine the merits of its dynamic performance, from the cool open T55 screen real shot chart view, cast high-speed movement Looking down the train window to see the opposite house, the edge of the house is very clear, and you can clearly see the branches of the branches! The contour of the mission in the carriage is also clearly recorded, and there is no phenomenon of smearing off frames.

From the test results and standard test discs, we can see that the dynamic test performance of Cool Open T55 is at a high level, and maybe a picture is not convincing. Let's take a look at other screen shot samples.

Screen shot proofs

Summary: In the actual screen capture process, cool open T55 performance is quite good, thanks to its MEMC stable technology, taking into account the 4K high rate of separation when the intelligent optimization of the motion picture compensation, to solve the screen jitter, smearing, ghosting, Watch the game more clearly with the game. From this price point, cool open T55 performance is absolutely worth the money.

In this test, from the perspective of 100% enlargement, we can see whether the scenery on the other side of the train is clear through the train window to determine the merits of its dynamic performance. From the perspective of the real shot of the PPTV-55T, the car The outline of the housing estate on the other side of the window is very clear. Under high-speed movement, the customer's figure in the carriage can be clearly identified and there is no phenomenon of smearing or blurring.

Let's take a look at screen shots.

Summary: In the actual screen capture process, no matter how complex the color of the screen or how fast the screen moving speed, PPTV-55T smart TV can be clearly displayed, and the screen color saturation and layering are well expressed.
