The bass module is easy to install. Press the four corner holes into four fixed positions, screw on the screws, press on the rubber cap, and plug the cable “plug”, and you're done.

Follow-up we will use some professional fever audition music to test the cool open T55 sound quality, so stay tuned.

Quality performance

Next, we will enter the test of quality testing, Super HiVi Cast, and we will conduct more detailed testing on the color transition, contrast, and three-color reduction capabilities of the CoolTV T55 TV to test the potential strength of this product. The following test images were taken in the standard mode (for the reference only after the screen shots were taken for multiple digital conversions after the shooting and the reader's display device performance was different).


Cool open T55 color grade transition performance

From the color ladder screen on the picture above, you can see that the overall color transition of CoolTV T55 TV is smooth, and the dividing line between each color block is clearly visible. The blue and red patches at the tip of the triangle are still well-graded, and they perform quite well. They are slightly lacking in green, and the transition of a color patch at the tip is not clear. It can be seen that the cool transition of the T55 is blue, red, and green, and the performance of the T55 is considered to be a mid-level deviation in the LCD TV.


Cool open T55 color saturation performance

In the color saturation test, the overall effect and the color reproduction ability of the cool open T55 TV picture are very good. From the test chart, it can be seen that the screen display effect is realistic and natural. Just like the one in the real life can be seen by oneself, the saturation performance is substantial.

Summary: Cool open T55 color quality performance in the LCD TV is a middle level.

4K quality experience

Next we have to test the 4K display of the Cool Open T55. First of all, we prepared a few 4K resolution pictures, let you further understand this TV's 4K static picture performance.


Cool open T55 4K static performance

In the test chart, cool open T55 TV color performance is clearly structured, the color as a whole is transparent and natural, 4K level display, detailed analysis is in place, click on the big picture can be more deeply felt.

Cool open T55 4K video character performance

From the test, we can see that the details of the characters and food are extremely clear and the resolution is high. Even every lash and each pore on the face of the character is clearly visible, and it is quite a body under the 55-inch screen interpretation. Immersive feeling.


Every eyelash, every pore is clearly visible

Next is the 4K TV's core playback capability. We played the crowd run video. The video has many characters and a large code rate. The CPU and GPU of the general configuration will all have cards, which can clearly distinguish between high and low configurations. In this test, the CoolTV T55 TV played well and did not have too many cards.

Motion Picture Test 1 Afterimage Test

Cool open T55 also equipped with MEMC motion estimation and motion compensation technology (Motion Estimate and Motion Compensation), designed to solve the problem of smearing under the dynamic picture, simply the screen response problem. We first test the cool open T55 with a screen test software. As all photos are taken on the ground, the objective factors such as environment and equipment will have a certain impact on the final presentation. All the pictures are for reference only, and the specific conclusions are based on the textual discussion.

The afterimage test is the switching between the color blocks through the screen to see if the color blocks leave an afterimage on the screen.


Cool open T55 screen blur test

The test result is that in the normal halogen lighting environment, it is almost invisible to the naked eye, which shows that the cool open T55 screen is satisfactory in response time, which also let Xiaobian on the next The performance of the MEMC sports engine is more confident.

Motion Picture Test 2 Game Application

Next, we will conduct a series of practical application tests on Coocaa T55 through games, movies, and video clips. The main test direction is the screen response speed (whether it is trailing at high speed motion picture).


Cool open T55 dynamic performance game test

The equipment for this test, Xiao Bian used Sony's latest next-generation multimedia game console PlayStation4 (hereinafter referred to as PS4), enough to represent the current game player usage.


Football game performance test

Football games or football programs are a harsh test for the response time of television screens, because when the television is playing football, there will be multiple continuous moving points on the screen. These points include various indicators on the field. The player, more importantly, football. Football is the point of the most high-speed movement. At the same time, it also focuses on everyone's eyes. Of course, this includes us in front of the screen. We need to stare at it intently. If the response time of the TV screen is too slow at this time, it will cause the football in the picture to be half like a comet, dragging its long tail. To facilitate understanding, the following comparison is based on a concept map. To describe. It can be seen from this that the dynamic picture differences between products with professional dynamic response technology (MEMC) and products without such technology are huge.

Football game performance test

We actually experienced it through video: From the video, we can see the most realistic look of the Cool Open T55. All videos are recorded at 720P and 60 Fps. However, due to the restrictions of the official video network, all video can only be transmitted at a frame rate of 30 Fps after transcoding. Even if this is the case, it can be seen that the trajectory of players and football in sports is very clear.

Basketball game test

In order to comprehensively evaluate the advantages of Coocaa T55 in dynamic response, Xiaobian additionally tested a ball game, from NBA2K15 of 2K GAMES, to see how this game performed on the CoolStart T55.


Cool open T55 dynamic performance test

This game is also a game that does not lock 60Fps, so the requirements for the dynamic picture is not low, plus the rhythm of the basketball game is so fast that it is very difficult for Xiaobian to capture still photos in the game, although Photographs taken through the device are still slightly blurry, but the picture is still very clean and neat.

The NBA2K15's recording video on CoolTV T55 is as follows. One thing that needs special explanation is that when many TVs are externally connected to multimedia devices, it often happens that the external device's command input and input are not in sync with the TV's display content. This kind of problem may seem inconspicuous, but the user experience This will have a huge impact, especially on the game side, but the Cool Open T55 is completely synchronized.

Racing Game Test

The racing game is also a type of game that requires a high level of dynamic display equipment. The reason for this is presumably understood by all of you. When watching motor sports, the car is strongly contrasted with the formation of surrounding reference objects. If the display device does not reach the proper range for dynamic control, the car itself will have unnegligible smears and ghosts. This is for the viewer. It is undoubtedly a disaster.


Cool open T55 dynamic performance test

In view of the particularity of racing games, besides performing routine recordings on video recordings, Xiao Bian also performed a group of close-range recordings on the rearmost part of the trailing phenomenon. The performance of Kukai T55 is very perfect. In the video, no smears can be seen at the end of the journey.
