First of all, thanks to Aunt Zhang’s love, I got the opportunity to test the new 4k TV in the micro whale. I will also try my best to write articles that can provide useful information for many valued friends.
When I submitted the public test plan, I said that I would compare it with several Sony TVs that I use in my home. And there are also enthusiastic friends drying up this TV, which is written in great detail. Therefore, in this assessment, my main focus is not to analyze the advanced physical parameters and rich network resources of this TV, but to compare this 4k TV with the familiar Dafa television sets and under different circumstances. Compared. The purpose of doing so is to let everyone understand the characteristics of this TV in practical use, so not only looking at the data on the paper and running the sub-information, it may be more useful for everyone.
There may be a bit of nonsense in front of it. Some friends will not be able to go on. Then I will tell you the conclusion of this assessment. Although the Whale WTV55K1 TV is not perfect, it is definitely enough for ordinary TVs and movies. The appearance, operation and stability of the system are also good. If everyone in the living room is ready to buy a TV, usually watch TV and movies. , Even connected to the computer when the big screen 4k monitor is used, is one of the options worth considering!
Specific reasons, and listen to me slowly:
Out of the box
On the day of the anniversary of the War of Resistance, STO had called me and said that there was a large package that could not be delivered. If they did not go to their shop to pick up the goods, they would directly return goods... (What is this attitude?) Well, I know It was the TV arrived, so I suppressed ten million mud horses in my heart. When I drove to express delivery, I realized that the original micro whale company was such a real one, playing such a perfect wooden frame...
This wooden frame is really big enough. Only by removing the wooden frame at the express delivery can we force it into the back seat.
When I arrived at home, I began to unpack and I skipped the word XXXX here. I just introduced a few features:
All the accessories are packed in this square box, very neat and careful.
The outer frame of the TV is very narrow, and it is very thin. There are already valued friends who say that the frame is thinner than the diameter of the one-dollar coin.
The sideline of "Thaojin" is still very delicate.
The back interface is perfect, 3 HDMI terminals also meet the needs of most families (Cable TV set-top box + network TV set-top box + DVD player)
Although the direction of the plug is directly backwards, the right-angle power plug also solves the problem of TV wall hanging, which is very careful and clever.
The remote controller is relatively thick. Compared to those paper-like remote controllers of various boxes, this slightly thicker remote controller has a better feel and is less likely to be misused, and is also more suitable for middle-aged and older friends.
Out of the box and the appearance is here, I feel that friends who haven’t watched can move to these three articles

Connect computer test
At the very beginning of the test, I used the computer's dp interface to output a 4k signal to the HDMI connection via a cable to see if it was clear. The actual effect is as follows
The connection was very simple. The first time the TV was successfully lit, there was no limitation on the 4k resolution transmission due to the DP-HDMI transfer and the HDMI version.
The screenshot shows a very domineering, the left is the notebook's own 1080p screen, this resolution, already "shadowed".
Using this TV as a large screen to read books is very cool, and at a viewing distance of about 60cm, the pixels of the screen are completely invisible, and the display is also perceived to be exceptionally clear and stable.
However, if you look closely at the screen, you'll notice that each black text has a white line around it, like a sharpen filter in the PS, but it's clearly too harsh because of the contrast.
In fact, the solution is very simple, that is, I use a custom image mode, manually clear the parameters down, this white box is gone. It's estimated that engineers want the TV to turn on and let everyone get a brighter feeling. The result accidentally brightened me...
Well, connecting the notebook found 4k signal connection is normal, and can point to point display, it seems this cargo 4K RGB screen is genuine, simple connection test is here. Compare the test below.
Comparison Test with Sony HW40ES Projector
The front is just the warm-up of this TV. Here's the real comparison test. The first thing that came out was the Sony HW40ES projector. Although television and projectors are not directly scientific, and because of the limitations of their lighting principles, they have many limitations. But now many families have a question. Do I watch movies in the end to buy a projector or a TV? For this question, I will first explain this comparison test. All the following screens are shot on a D600+24mm lens on a watching couch. The screen is a 119-inch sound-sensing picture frame with a viewing distance of about 3.2 meters. Please pay attention to the relationship between the angle of view when watching. In addition, in order to make up for the huge difference in brightness between the projector and the TV, I have turned the HW40ES projector bulb output to "high", which means that there is at most 1700 lumens of brightness output; at the same time, the brightness of the TV is "47". More comfortable values. However, everyone can still feel the difference in the brightness of the projector and the TV in the photo.
At the same time play "beauty eat roast duck" 4k source, because the projector is a 2k model, so the picture details defeated. For example, in this scene, the green indicator of the safety exit that the beauty enters at the door, the 4k TV at a close distance can clearly see the above word, and through the projector, we can only see the outline of this indicator, and through the approximate position and blur The image "brain" makes the word "safe exit." However, this kind of detail is not so strong in dynamic images, and due to the small size of the 4K TV, this difference in detail is not noticeable on the sofa.
For scenes that rely on depth of field perspective, due to the larger screen, the difference between blur and clearness can be made obvious. On the contrary, if you look at this blurry level of 4k TV, it seems that the depth of field is not enough...
This scene is a scene with extremely high requirements for the texture of the picture. Here we have to say one thing. Because of the projector's huge screen size advantage, this texture is evident on the 119-inch screen. The extreme sharpness of the cloth in the vicinity and the blurring out of the focus form a very strong contrast, allowing the whole cloth to appear three-dimensional. Although the 4k TV wins in the details of the vicinity, the blur and the entire color reproduction in the distance are still surpassed by the projector.
Close up details of the eye. Everyone can see that the 4k TV shows extremely clear pixel particles, and indeed every pixel is clear. However, the following projector effects on the 119-inch screen, although the definition is not so extreme, but the exaggerated contrast and excellent color reproduction, with a very real reduction, makes people more convinced.
Slightly sum up, if you are a real cinema lover, like the large screen and the so-called movie texture, then the projector is your dish. At present, it is impossible for a television to physically meet your requirements. Therefore, it is not possible to place too much demands on microwhales because he is just a TV.
Comparing with Sony 70W850B TV
After watching the contrast test with the projector, we moved the TV back to the living room. After the test, the two TVs were connected simultaneously through the HDMI splitter to achieve the purpose of picture synchronization.
The test here is completed in the second floor of the empty hall, the lens focal length of 35mm, sight distance of about 5.5 meters, or please pay attention to the size of the perspective in order to buy a TV at home as a reference.
It can be seen that under this line of sight and application, the 70-inch TV is not big enough, and the 55-inch micro whale is relatively small. Because it takes care of Sony's 2k TV, the signal output from the laptop is a 1080p resolution signal. Looking at the distance between the two TVs at this distance does not seem to have much difference.
However, at a closer look, it will be discovered that under the blue solid color screen of the micro whale 4k TV, there is no Sony TV so clean, with such distorted color patches. And this situation did not occur when directly outputting a 4k signal. What is certain is that this kind of impurity is actually generated when the 1080p signal is upgraded and the 4k signal is played out. In other words, the conversion circuit of the micro-whale TV may have a little problem, and it will output such an impurity block, hoping that this bug can be repaired later.
Then, use a notebook computer to output the classic monitor test program displayx. When it was all black, the entire display of the micro-whale TV showed such a deep purple, and the behind-the-scenes Sony TV was actually a dark one... (In this case, shouting loudly: Sony Dafa is good!)
We can also see that the top Sony TV can also distinguish all the color blocks except the 1, 17 and 2 color blocks. The difference between the micro whale and the black whale is obvious, and the overall black color does not come down. , causing many dark color blocks to be indistinguishable.
Then, continue to detect whether the backlight modulation of the whale TV flickers. In the 1/2000 second shutter continuous shooting, we can clearly find that the pwm modulation method used by the micro-whale TV has obvious large-area black screen phenomenon, and the phenomenon of the Sony 70w850b is significantly reduced, only the middle of the last picture. Dark stripes appear. In other words, the pwm frequency of the Sony 70w850b is significantly higher than that of the small whale TV. This may be dissatisfied with many parameters of the party.
Now let's take a look at the micro-whale TV in the case of actually playing a movie.
The color of the whale TV is more vivid, and the overall picture is brighter. But looking at it alone, the picture is also very seductive. Compared with the 70w850b, it is only slightly worse in the dark details.
To sum up, in the large living room scene with a viewing distance of 5.5 meters, the size of the small whale TV 55 is slightly smaller. Although its black level and pwm modulation method have certain flaws, this gap is not large for actual viewing, and it may only cause you psychological discomfort.
Comparing with Sony 40R480B TV
The TV was originally used in the bedroom. It was not suitable to measure it in the living room. However, considering it as a representative Sony low-end machine, it is still necessary to compare it. After booting, we can obviously feel that, although it is Sony's low-end models, but its color tuning is still somewhat similar to the 70w850b, both of which are relatively soft and slightly yellowish feeling.
It also plays 256 grayscale signals.
Above is 40R480B, the following is a small whale TV. A close-up of the top left corner shows that even the low-end Sony 40R480B is still stronger than the micro-whale in the performance of the black level.
To sum up, the black level that Sony's low-end TV can display means that most TVs can perform such black level performance. However, micro-whale TV still loses here, indicating that it has a certain amount of screen or processing circuit. The lack of. However, back to watch the video, the micro-whale TV does not feel bad, because the screen size difference, the overall feeling of a small whale TV is stronger than the 40-inch Sony TV.
Comparison Test with Sony 60R520A TV
In order to compare the complete test of the micro-whale TV, I also fight. In the smaller living room of another house, we came to contrast the old low-end machine N years ago, the Sony 60R520A. The viewing distance of this living room is about 3 meters. The previous 60-inch TV has already felt relatively large. After so many years passed, the landlord still feels that the size of this TV is just enough. This time, putting two big guys on top of the TV cabinet is also very spectacular.
Or to test 256 gray scales. Above the old Sony's grayscale actually performed quite normal, but still lost more than a small whale.
The same applies to 1/2000 second shutter continuous shooting, found that Sony 60R520A with the same micro whale has a large black screen phenomenon. And by the way, it can be found that the backlight uniformity of the bottom edge of the 60R520A screen is very poor, but after looking at it for so many years, I haven’t found it yet...
By comparing the same movie clips, we can find that the color of this Sony TV does not have the “film sense†of the two previous ones, but there is a sense of overwhelming defeat.
Watching television at the same time, we can see that in the cable TV programs that are much smaller than the movie color and information volume, we did not see the obvious difference in the color of the two TVs. Or rather, this difference does not affect the viewer's mood.
Some people say that 4k TV is not as good as 2k TV. I'll give a detailed picture here, which is the "front" word of the front knife. It can be seen that although the 4k TV is able to satisfy the resolution of the 4k screen by interpolation calculation, its font edge is clear and smooth, and it is definitely not worse than 2k.
What deserves recognition is the signal source selection interface of the Little Whale TV. There is a thumbnail image of the current source, which provides many conveniences for the elderly in the home.
Finally put a picture, two TVs watching different programs at the same time, so cool! I like to watch TV so much since the 2008 Beijing Olympics.
To sum up, the small whale TV compared to the old Sony 60R520A TV, although the pure objective test has its own outcome, and its color, brightness, and size are not exactly the same. But for such a living room environment, the gap between the actual viewing effects between the two can be ignored. In addition, the richness and ease of use of the resources of the micro-whale TV network are not comparable to those of traditional TV manufacturers. This also adds a lot to it.
Full text summary
This article compares and tests 4 Sony devices including projectors. For friends who like Dafa and superstition, they can refer to it. Although micro-whale TV shows some limitations when comparing different devices, there are no bugs that can affect the viewing mood.
1. In the connection to the computer test, we can see the real 4k resolution of the micro whale TV, and the huge sense of wideness when watching still pictures and documents makes people feel better than 4 1080p screen splicing practices. Therefore, users with such needs can use it as a computer monitor and hang it on the wall behind the desk.
2. In comparison with the HW40ES projector, we can see that its 4k resolution is still one of the advantages, although this advantage does not look obvious when the viewing distance is more than 3 meters. However, the huge size gap with the projector, destined for this TV is not suitable for pure cinema applications.
3. Compared with the 70W850B, the black position and backlight problem of the microwhale TV may be seen by the sharp-eyed friend in one second, but in general in the larger living room, this size TV is "see Bright, listen to a ring, the actual experience is not so ok, visible TV's main parameter is the size! size! ! size! ! ! (Important things say three times) is the so-called "a big cover hundred ugly", the other parameters are now not a big gap between the various manufacturers, this time the cup theory is very important.
4. Compared with the 40R480B, the small whale TV's larger size, of course, surpasses the 40R480B's sense of experience. In other words, in the larger living room, we must choose a large enough TV. When the size is too small, we can say that the TV is meaningless.
5. Compared with 60R520A, the objective performance of the two is not big. And when watching cable TV programs, they did not find the theory that the big gods alleged that 4k is worse than 2k. Of course, whether or not the 4k resolution does not come out much in the sight distance of 3 meters... With a lot of sources, connecting to the wireless network will allow you to watch many programs. This is a great advantage in comparison. After all, we are watching TV programs, not the TV itself.
Last words
The micro-whale TV also showed great sincerity in this survey, specifically called to inquire about the assessment situation, whether there is a problem that needs feedback, which fully explains the importance of manufacturers on the product, such manufacturers are worth our looking forward to. For the various television sets of the various gods, I just put forward my own point of view here. The size of the TV is always one of the most important indicators. It is not necessary to search for an inventory by selecting an old flagship machine to break through the iron shoes, and reluctantly cut the size of the 5-inch TV. Because of the TVs bought back, we rarely have the opportunity to compare the 1vs1 tests. There is no gap in the so-called comparison. The TV was originally a pleasure to watch, as long as the quality is reliable, easy to operate, just like my Sony 60R520A, after reading for so many years, I discovered that his backlight was so uneven...
