[Projection TV]How about home projection TV, which is better, projector or TV
Comparison of screen size ratio:
Nowadays, the size of LCD TVs in many households is between 30-60 inches, while the projection size of current mainstream projectors Can reach about 80 inches. Regardless of other performance comparisons, projectors have a wider field of view than TVs in terms of screen size.
Comparison on space usage:
In this indicator, projectors have a smaller footprint than TVs. The projector size is smaller than that of the TV, and the space usage is more economical. Even if the projection screen is used, it can also be set to be retractable. However, TVs, especially large-sized TVs, must be placed in a suitable position in a certain space, and the space usage is poor.
Resolution:
On the issue of resolution, I think both projectors and TVs are tied. The current mainstream TV and projector resolution can reach 1080p or 4K picture quality.
Image quality comparison:
When the TV shows the close-up of the face, it is very delicate at first glance. There will be a sense of painting, and the color will be warmer. The color tone of the picture projected by the projector is relatively cold, but the stereo effect is good. In terms of the facial expressions of the characters, both the TV and the projector are equally detailed. Although the brightness of the TV is very high, it is obvious that the edges of the objects on the projector screen are sharp, and the pores and wrinkles on the face are better displayed. It is also more real, without the cold and illusory feeling. Especially when watching a movie, the projector can fully express the texture of the movie picture, so that people can feel the joys, sorrows and sorrows of the characters in the play at first glance. This playback effect can make the audience quickly integrate into the movie, and There is no sense of alienation.
Among the three major factors that affect image quality, black level capability is particularly important. Because this indicator directly determines the quality of the contrast, it also has a direct impact on the saturation of the color. The projector’s black level performance is very good, the picture has layers, and the details of dark scenes such as clothes and hair are rich, and it will not interfere with the color performance in a bright environment and cause the saturation to drop. It is understandable that the contrast and black level of the projector are higher than that of the TV, especially when watching European and American blockbusters.
In terms of color performance, both are very good, but due to the color tone, there are still differences in color expression, and from the overall point of view, the color of the projector is very soft. A must-have for big-screen video.
3DComparison of effects, advantages and disadvantages:
From the perspective of imaging effects, TV The imaging effect of the TV should be clearer, because the TV plays the picture in small pixel blocks one by one. The more such blocks, the better the imaging effect and the more realistic the picture effect. At the same time, the brightness of the 3D TV can be effectively adjusted, and the corresponding transformation can be carried out according to the needs.
For now, the performance of 3D TV is getting better and better, and the more additional functions it has, the network cable can be connected separately to enjoy online videos. At the same time, the multimedia playback function has gradually matured, and some videos can be played easily, and the playback of pictures and audios is not a problem. Another point is that 3D TVs can easily and freely convert between 2D and 3D, making appreciation flexible and natural.
The advantages and disadvantages of TV 3D effect: strong stereoscopic realism, shocking visual impact; high brightness, high contrast, high-definition picture, no ghosting, natural and realistic; compatible to play 2D/3D content, the picture is free convert. However, watching 3D effects on TVs can easily lead to “eye fatigue”; its price is too expensive
Current projectors, from a single function to the current one that can play multimedia functions, and can increase the sound function by real-time voice, This greatly enhances the optionality of projectors. At the same time, some projectors can also be connected to the Internet to enjoy high-definition videos and pictures on the Internet at any time.
The brightness of the 3D projector has also improved with the requirements of use, ranging from 1000 lumens to more than 100 million lumens. The increase in brightness enhances the clarity of the picture, but because the projector is based on the light source The projected picture is not the same as the TV, so the projection of the light source will be subject to some external interference. Thereby affecting the display effect of the screen. The lumen is proportional to the electrical power. The higher the brightness (lumen), the greater the power consumption, the greater the heat dissipation, the greater the exhaust air volume, the greater the noise, and the higher the cost.
3D projector advantages: low cost; good image quality and does not require much additional equipment; the most stable technology
content comparison:
In terms of viewing content, the TV can be expanded through WiFi, boxes, etc., to increase the depth of viewing video content. The projector requires external content to play, which is inferior in content selection. But now some smart projectors also have built-in video resources, WiFi connection and other functions, which also greatly expands the choice of content viewing.
Summary:
As for the question of choosing a projector or a TV, the author thinks that the wise man sees the wise and the beholder. Although the projection size of the projector and the performance of some pictures exceeds that of the TV, the TV still completely suppresses the projector in terms of content and so on. Moreover, many families have been accustomed to the practice of buying a TV for a long time. Maybe the phone is just another entertainment tool besides the TV. However, it is still impractical to completely replace the status of TVs in terms of the current performance of home projectors.
