The first step is to consider your own environment. The biggest advantage of laser TV is that the screen size is large enough, so the application environment of laser TV is generally in the living room, or it can be in an independent video room. We mainly analyze the living room environment. After all, there are not many people who own an independent Dapingmi video room.
The location and orientation of the living room are more important. Most people's living rooms are sunny, and the video wall is generally located on a 90-degree wall of the window. In this kind of house design, the living room sunshine is actually more abundant. This also means that if you watch a laser TV at noon, the sun will affect the picture.
Content and interface should pay attention
What to look for after buying a laser TV? If you like to watch TV programs, then you must ensure that your home is equipped with a digital set-top box, because these set-top boxes are generally equipped with HDMI output interface, and laser television products also have HDMI input interface, the two docking is not difficult. And if you are still using the AV interface or RF interface at home, you should pay attention to buying laser TVs in this case.
Many laser televisions do not support the direct reception of television signals. There are no modules within the machine that handle the television signals. For homes without HDMI interface equipment, when buying a laser TV, pay attention to whether the product supports AV interface or RF interface, and if laser TV does not have such an interface, you are willing to buy the corresponding interface (the transfer interface may be Affects clarity).
Size and material screen issues sloppy Next we have to consider the screen size and material. In general, if it is a small apartment, such as a two-bedroom apartment with more than 80 square meters, a 100-inch laser television projection will suffice. Because the large size needs a certain distance to watch, it has the best visual effect. If the distance is too close, the eyes are tired, and it is also not good for the viewer to maintain the correct viewing posture.
According to the visual principle, the clearest and easiest distance to observe the image is a 20 degree angle of view and a 35 degree angle of view. Calculated by height, the optimal distance is 4.2373 meters. Calculated according to width, the optimal distance is 4.21 meters, and 4.22 meters is selected considering the best distance. Of course, this is only a theoretical distance. In fact, the viewing distance is also related to the resolution. If it is 4K, then it can be closer. I believe that between 3.5 and 4.2 meters is possible. If it is 1080P, it can be designed according to the standard of 4.2 meters.
Finally, the price 1080P is more practical After considering the above issues, we consider the issue of price again. Laser TV currently starts from 10,000 yuan and has a product distribution of more than 100,000 yuan. Among them, the price of 4K resolution laser TV is relatively high, basically all above 50,000 yuan. For the average family, 4K laser TV is not very practical.
Million dollar laser TV price is actually good. Why do you say that? With a budget of 10,000 yuan, a 100-inch or even 120-inch screen size is available in the home. At present, only products such as laser televisions are satisfactory. At the same time, the color, the fineness of the screen, and the system performance of the laser television are no worse than those of the LCD TV.
