Hello everyone, I am @Yong Wuzunjing . In fact, projectors are very common in life nowadays, but many people do not know what pitfalls the projector needs to be avoided when purchasing a projector. They often buy projectors that are not suitable or have low cost performance. This article is my summary of the purchasing experience, pit avoidance guide and cost-effective projector recommendations that I have summarized in recent years. I have summarized the key points of the purchasing of the projector in a simple and easy-to-understand manner, and they are full of practical information. Even a projector novice can understand it. I believe that everyone will gain something after reading it. The article is a bit long, so it is recommended to collect it first and read it slowly.

First, let’s briefly understand the advantages of the projector.

1. Why buy a projector?

(1) Improve the viewing experience

I am a nine-to-five office worker. I usually like to stay in my room after get off work or on weekends to watch my favorite movies or variety shows. Because I often watch dramas, I pay great attention to the viewing experience. Some people say that it is okay for us to watch on our mobile phones? Why buy a projector? As a projector enthusiast, I can tell you responsibly that the larger the screen of , the better the viewing experience . If you use a good projector to watch TV series or variety shows, the atmosphere and sense of substitution will be stronger. Just imagine, on a rainy weekend, I can’t go out, so I just pulled the curtains, closed the door of the room, took a drink from the refrigerator, bought a bucket of popcorn, chose a movie, and slept on the sofa to watch it. Isn’t it a great pleasure? This atmosphere is unfeelable when viewed on your phone.

(2) More applicability and flexibility

Sometimes we are not convenient for us to watch videos in the same place, for example, sometimes we want to watch TV while eating, such as I sometimes like to eat in the living room or kitchen, and sometimes I don’t want to be disturbed by others, I will be in the room directly; when I go out for a trip, I will also bring a smaller projector for easy viewing; I also like to follow the videos of fitness experts often. So at these times the benefits of projectors are revealed, which is more convenient for our daily needs. No matter which area of ​​my home I want to eat, no matter where I want to travel, no matter where I want to exercise, just move the projector to meet my needs, which is really convenient. Some projectors also have eye protection modes, which can better protect our eyes. Even if there are children at home who want to take online classes, you don’t have to worry about hurting your children’s eyes.

2. What cost-effective projectors can be purchased directly?

During the process of purchasing a projector, I have compiled several projector goodies after a lot of actual tests. If a friend is anxious to buy a projector and is worried about stepping on the mine, you can start directly from the following products according to your budget, which is very cost-effective.

1, Xiaoming Q1Pro:

Fans often ask me if there is any cheaper entry-level projector recommendation. This Xiaoming Q1Pro is just that, with a price of more than one thousand, and the trapezoidal correction + autofocus + automatic screen obstacle avoidance functions, lumen 00ANSI, 1080P physical resolution, although it cannot be compared with a few thousand, the price is there, worthy of this price, it also has a thoughtful voice control function. Although it is small, it can project 40-120 inches of pictures, which is very friendly to rental houses. I have also arranged one for my parents' home.

2, Big Eye Orange X11:

The biggest feature of this Big Eye Orange X11 is that it is equipped with an optical zoom lens, which can zoom in and reduce the projection screen without moving the machine to meet more apartment needs; 2300ANSI lumens +1080P resolution, basically the brightness that can only be achieved by 5k+ price projection on the market, the X11 configuration is directly full; it supports automatic keystone correction, sensorless focus, 3D projection, and you can easily watch 3D blockbusters at home. It has a high cost performance and can be earned.

3. Key points for purchasing projectors

When purchasing a projector, you must measure the cost-effectiveness of the projector. Not only should you consider the brand awareness of the projector, but you should also consider the use scenario, personal preferences, actual budget, parameter configuration and other factors. Next, I will give you a detailed explanation.

1. Confirm the demand (what is used to buy a projector?)

(1) If you are an office worker buying a projector, then you must be worry-free enough.

We buy projectors to relax during rest time. We must consider the running speed. The boot speed must be fast enough. Try to reserve more time for yourself to relax; the running memory and storage capacity must be large enough, and match flagship AI chips at the same time, so that the overall configuration can be hard-core, the running speed can naturally be increased, and the reaction speed will be very excellent; the adjustment should be simple enough, it is best to just turn on the computer by hand, and all other adjustments will be automatically completed. Since you choose to watch movies and games after get off work and relax yourself, you must All operations should be simple enough , and you don’t fill in the blockage for yourself. How to do it comfortably.

(2) If the projector is to be given to the elderly, the search operation must be simple.

Try to choose a projector that supports voice control . The elderly can express their needs and let the projector execute automatically, which is much more convenient. It can support large font large poster, so that the elderly can watch it more comfortable; of course, it is also necessary to automatically adjust . Although it is a technological product, the elderly can also get started quickly without manual operation, everything is automatically completed, and the operation is simple and convenient!

(3) If there are children at home, eye protection should be taken especially.

Choose a projector with low blue light mode more suitable, it can effectively filter out blue light protect children's eyes, and children can also better avoid eye fatigue when taking online classes for a long time; in addition, it should also ensure direct light, and support intelligent screen break . When the child is close to the light source, he can automatically recognize and screen break; it is also necessary to support voice control . When the child wants to watch cartoons, he can directly say it and play it. He doesn't have to let his family come to help every time he watches cartoons, and the child is more confident in solving problems by himself!

(4) Confirm personal preferences.

For friends who pursue sound effects, a good audio system is more important. Whether the sound is delicate or surging, it can reach the heart and feel the beautiful world brought by music; for friends who pursue fast running, the hard-core configuration of is more important, with larger running memory, larger storage space, and more powerful flagship chips. The overall performance of the projector is maximized, and the response speed is of course faster. Choose what you like directly, and you can skip the waiting process directly.

2. Confirm the budget

Generally, for projectors, entry-level products must at least have large screen projection, clear enough picture, and no lag in video playback. If you want to choose a smart projector, then the minimum budget should be about 2,000 yuan. This projector will not cause too much psychological gap when used. If conditions permit, you can choose a high-priced and cost-effective . Generally, this type of projector will be equipped with a more powerful system and configuration, which can meet the high needs of more people. However, when purchasing a projector, the more expensive it is, the better. Just clarify your needs and choose a cost-effective projector that can meet your needs within your budget.

3. Key points for projector purchase (including pit avoidance guide)

(1) Standard resolution

Projector projector's projection picture is mainly determined by the standard resolution parameter. Generally speaking, the clarity of the projection picture will be enhanced with the improvement of the standard resolution (4K1080P720P480P) . At present, projectors with standard resolution 480P are generally used as office teaching tools, because the main projection of work report PPT and courseware PPT during office teaching process. The elements that need to be displayed include text, graphics, etc., and the clarity of standard resolution 480P is basically sufficient.

Home projector, the standard resolution 1080P is the most common, which can meet the basic needs of home film and television entertainment. If the projection quality requirements are relatively high, you can choose a projector with a standard resolution 4K. This projection picture has richer details and clearer details, and can present ultra-clear image quality.

But! Pay special attention here. When the standard resolution is the same, if you want to compare the picture clarity, you must use display chip size as the benchmark. Some projectors on the market currently have projector resolution fictitious marks, so everyone must know how to distinguish the size of the display chip when purchasing: usually has a larger display chip size at the same standard resolution, the higher the picture clarity , 0.47”DMD0.33”DMD0.23”DMD ,If the standard resolution of the projector is 1080P, then the projector equipped with 0.47" DMD's picture clarity is higher than that of 0.33" DMD's projector.

(2) Luminity

Luminity This parameter indicator basically determines our viewing experience, so everyone must pay attention to luminity and luminity when purchasing. The higher the projector, the brighter the projected picture, the better the user experience. In the early years, I found that some projectors will have a serious problem when projecting: the picture brightness is too low, the image appears very blurred, and it is even more difficult to see clearly when used during the day. This kind of projector will have this situation mainly because the projector's lumen is too low.

You should also pay special attention here, You should pay attention to whether the merchant is marked with ANSI lumen or light Source lumen.

ANSI lumen is the international standard unit of projector lumen recognized by the world. It represents the brightness projected by the projector, which is the most intuitive feeling of our human eyes.

Light source lumen refers to the brightness of the optical machine in the projector. In fact, the brightness projected by the naked eye will be much lower than the brightness of the light source lumen. Therefore, the light source lumen is not of reference value.

Nowadays, most manufacturers will mark ANSI lumens on their products, but some small manufacturers will deliberately hide this unit, the lumens of virtual label projectors. If the merchant marks the light source lumens, it is best to ask the ANSI lumens of the projector.

(3) memory

The memory of the projector includes running memory and storage memory.

run memory is the temporary storage space of the projector's operating system and program, so the larger the running memory of the projector, the more programs can be run in the background, and the faster the running program can be run.

storage memory . When we buy mobile phones, we usually pay attention to their corresponding storage memory. The same is true for projectors. The storage memory size of the projector determines the software that the projector can install and the number of audio and videos downloaded. The same principle is the same as the mobile phone computer. The larger the storage memory, the more convenient it is to use.

(4) Transmission ratio

Transmission ratio is the ratio of the projection distance to the screen width. The smaller the transmission ratio, it means that the projector is projected with the same width. , the shorter the projection distance of required, the smaller the environment and occasions are restricted during projection, and it can adapt to more occasions. Therefore, if you buy a projector, you need to consider using the size of the environment to choose.
