Traditional CRT TVs are difficult to make larger because of the limitation of the imaging principle. No matter how large, they can only be achieved by collage. It is relatively easy to increase the size of LCD TVs. Looking at the larger and larger TVs, do you think the bigger the better? In the process of buying a TV, you may have a similar idea. Let's take a look at the following five mistakes in buying a TV.
The bigger the TV, the better?
The choice of TV size is based on a certain basis, generally based on the viewing distance. At present, most consumers have a living room area with a viewing distance of 2.5-3 meters, and the corresponding TV size is more suitable for mainstream 40-inch and 42-inch specifications. If you choose a large-size TV with a size of more than 50 inches, you may need a viewing distance of 4-5 meters. Otherwise, not only the best viewing effect will be achieved, but long-term viewing may also cause visual fatigue, and may even cause dizziness and myopia.
In addition, most of the large-scale flat-screen TVs in the store are heavily promoted as early transition products, whether in terms of performance, function or design, compared with the new flat-screen TVs, they are all inferior. . Therefore, it is better to choose a large-size flat-screen TV with a large promotion force than a mainstream mainstream flat-screen TV suitable for you.
In addition to the mainstream living room requirements, for the second TV in the bedroom or study, a smaller 32-inch TV may be more suitable, so the size is determined according to the size of the space used.
Buy a TV as a monitor?
TVs are getting cheaper, LCD TVs are flicker-free, and it is also good to buy a large-screen TV as a computer monitor. If you have such an idea, it is best to experience the feeling of watching text on TV firsthand.
Since monitors and TVs are products of different classifications, the emphasis is of course different: monitors emphasize true reproduction, and TVs emphasize pleasing eyes. The brightness of the TV will be higher, and it will hurt the eyes more after watching for a long time.
Of course, this is not to say that the TV set must not be suitable for use as a monitor. In certain situations, such as watching movies and playing games, it is good to use a TV set as a monitor.
Is flashless 3D the best?
Speaking of TV flickering, the CRT TV of the previous generation may immediately appear in your mind. At that time, due to technical reasons, many TVs could only reach the screen refresh rate of 50Hz, so it seems to have some sense of flickering. So everyone will have some aversion to the word flashing.
However, due to the different principles of LCD TVs, there is no such obvious flicker. LCD TVs do not have the concept of flickering and flickering, while the 3D display technology of some models has the concept of flickering.
Flicker-free 3D is actually polarized light 3D display technology, corresponding to shutter-type 3D display technology. Polarization 3D technology does not change the refresh rate of the screen when watching 3D movies; shutter 3D technology needs to quickly switch the display screen of the left and right eyes, so the refresh frequency will drop by 50%, which is the reason for the so-called flash . However, the current refresh rate of shutter-type 3D TVs are all above 120Hz, and there will be no obvious flicker. And relative to polarized 3D, shutter 3D will not have a loss of resolution.
Don't buy if it's not 1080p?
Judging from the current trend, 4K seems to be popular, but the first thing to say here is not that high-resolution TVs are bad, but a problem between the price and the satisfaction of demand. The difference between the current 32-inch 1080p TV and 768p is more than 1,000 yuan.
Apart from the price, unlike the monitor, the resolution of the TV is not so important, the monitor tends to restore the reality, and the TV will more or less modify the picture to please the eye, more attention is Picture quality, specific items include viewing angle, number of colors, dynamic picture response speed, light leakage, etc. In this process, it needs to involve the liquid crystal panel, the backlight, the bit number of the processing circuit, the dynamic picture compensation / optimization technology, the reception and processing capabilities of the TV signal, and so on. Therefore, resolution is only one of the factors but not the most important. Don't just look at the resolution.
The price of 1080p is higher for LCD TVs of the same size, which is inevitable. It is a waste to buy it but not to enjoy much improvement.
Can Smart TV install many applications?
What is often seen in the slogans of smart TVs is the in-depth development based on the Android system, so many users will take it for granted that Android applications can be installed directly. If that is the case, it is still very beautiful. How about it?
In order to ensure good compatibility of applications, many manufacturers use their own application stores. Although it is a good thing, it also limits the diversity of applications. The number and quality of apps can only depend on the later support of manufacturers, but not every one. Have enough strength to maintain.
On the other hand, even some smart TVs can support three-party applications, because the resolution may not be adapted, or because the use of the TV is different from the touch screen of most mobile phones and tablets, it can only be operated by the remote control. Some better TVs can use a mouse or somatosensory remote control. These two characteristics make the application of smart TVs on the market greatly restricted.

Suggestions:
1.Clean the dust inside every 6 months to ensure the good heat dissipation and long life time.
2.Don`t keep too short distance to the plant canopy to avert leaves bleaching.
3.Highly hang the lamp will weaken the energy and affect the growth cycle of the plants, so the lamp should not be hang too high.
4.While taking care of the plants, please spray the leaves and branches 2-3 times everyday, to ensure the plants do not wrinkle a wither, and have no phenomenon of few fruit, and hard pericarp.
