Do you know the five major pain points of laser TV before buying it?

Laser TVs are gaining more and more attention, but many people don't know much about them. Although there are many articles on the Internet that explain the advantages and technical principles of laser TVs, those who have not come into contact with actual products, or have not actually purchased and used laser TVs, are still unsure about the pain points of this product. The author has summarized the five major pain points of laser TVs through communication with many brand manufacturers and collecting opinions from many netizens. Friends who want to buy laser TVs can learn about them first.

The product cannot be touched and installation is difficult

Laser TV is an ultra-short-throw product, which means that it can project a nearly 100-inch screen by placing it on a TV cabinet, so laser TV does not need to be hoisted. However, there is also a disadvantage of using it on a cabinet, that is, the machine is easy to move. Especially for friends with children at home, many children are full of curiosity, so they are likely to move products like laser TV. Once the laser TV is moved, it is difficult to return the picture to its original position.

The size of the laser TV screen, as well as the fit between the screen edge and the screen, are all determined by the laser TV position. Therefore, once the laser TV is moved, the user needs to readjust the screen edge and the screen position. This process is not as simple as imagined, especially for users who are not familiar with projectors. The reflective ultra-short-throw projection method causes the laser TV screen to not be a perfect rectangle. When adjusting the laser TV, it may be necessary to use functions such as keystone correction. Therefore, the adjustment process of the laser TV is relatively cumbersome.

How to solve this problem? Users can fix the laser TV with their own equipment. Some manufacturers also provide trays that can be fixed to the TV cabinet, and then the laser TV and tray are connected. This can solve the problem of the laser TV being easy to move.

There is no wireless screen projection function?

Many consumers tend to overlook such a function when buying laser TVs. This is the wireless screen projection function. Although the function of projecting the mobile phone desktop directly to the big screen is not yet mature, and many will experience delays or freezes, the screen projection function realized by video software such as APP is very reliable.

Screen duplication often lags and freezes

The difference between these two functions is that the former can project the entire screen of the mobile phone onto the large screen, and the process of the user operating the mobile phone can be displayed on the large screen; while the latter can only project the video resources in the APP, and cannot display the pictures, videos and other materials in the mobile phone. However, the latter is actually the most practical and reliable in daily applications. The "screen copy" function of the former is not only unstable, but the picture often has delays, and the user's mobile phone cannot turn off the screen after projecting the picture. The "APP projection" function is very stable, and after the projection is completed, the mobile phone can handle other things, and even turning off the screen will not affect the projection process.

With the APP projection function, if we purchase a membership of a specific video platform, we can directly use our mobile phone to watch resources on the big screen without having to purchase a VIP membership on the laser TV platform. This not only saves money, but also allows you to enjoy the super large screen and rich resources. Many laser TVs do not have this function now, which is actually very unwise. Therefore, when purchasing a laser TV, consumers must consider purchasing products that support wireless screen projection. In this way, the resources in the later stage will be rich enough.

What to do with laser highlighting of children's eyes

Some consumers have children at home, so they are worried about the safety of laser TV. Although the safety of laser TV has been tested, many national institutions have confirmed that normal viewing of laser TV will not cause physical damage to the user's eyes. However, many children do not follow the usual path. They are likely to look directly at the camera. As the saying goes, "curiosity kills the cat." What should we do if this happens?

There may be no problem watching the laser TV, but if you point your eyes directly at the lens of the laser TV, the energy of the laser will be much greater. Children's eye structures are not fully developed, so if they behave like this, it may cause some damage to their eyes. Many laser TVs do not deal with this problem.

However, some products have begun to consider this issue and provide a reliable solution, which is to install sensors on both sides of the lens. As long as an obstacle appears in front of the laser TV lens, the laser TV will automatically black out. In this way, even if a child curiously sticks his head in, there will be no problem of laser light hurting his eyes. Friends with children at home should pay more attention to this function when buying a laser TV.

The interface is too hidden and inconvenient to plug and unplug

The current laser TVs are basically the same in appearance, with the lens located on the top of the body and the interface located on the back of the body. In this way, when using the laser TV normally, the interface of the laser TV has to face the wall. The problem with this design is that when plugging in and out various data cables, users often cannot see where the interface is. If the laser TV is moved, the recalibration problem we mentioned at the beginning will occur.

Nowadays, people have more and more output devices, such as Blu-ray players, cable TV boxes, and game consoles. It is impossible to connect all these output devices to the laser TV. In many cases, people will only connect the cables when they need to use them, which requires frequent plugging and unplugging of the interface. Many netizens have reported that the interface of the laser TV is at the back, which is very troublesome to operate.

The author believes that frequently used interfaces, such as HDMI and USB interfaces, should be designed on the side of the machine body, so that it is convenient for users to operate the interfaces. Some interfaces that are not frequently operated can be designed on the back, such as movie interfaces, audio input and output interfaces, etc. This design is reasonable.

Manual focusing is inconvenient and troublesome

Another problem is the focus of laser TV. Many laser TV products provide manual focus, which is not very convenient. Users need to get close to the laser TV to focus. The current price of laser TV is not cheap. For a high-end product, it is reasonable to provide automatic focus. After all, it is not reasonable to make users run back and forth when operating the product with a price of tens of thousands of yuan.

In addition, due to the principle of the projector, the clarity of the picture will change after a long time, so the laser TV needs to be focused every once in a while. And when installing, it is more convenient to focus the picture from a distance, so that users can have a panoramic view of the whole picture and have a clearer understanding of the details of the picture. The author believes that the automatic focus function is still very necessary for products like laser TV.

Although laser TV is a new product, it is developing rapidly. Currently, many consumers are paying attention to this product. Many brands have also begun to enter this market. However, laser TV has only been around for a short time. Many manufacturers still consider this product from the perspective of traditional projectors and do not fully understand the demands of ordinary consumers. The author summarizes some of the pain points of using laser TVs, hoping to help manufacturers and ordinary consumers understand laser TVs.
