With the increasing popularity of high-definition concepts, high-definition TVs have gradually become mainstream, and the demand for large-screen visual enjoyment by home users has rapidly increased. For a time, the projector has become the best choice for large-screen display devices. A hot topic for many home theater enthusiasts. However, when I visited some users and dealers, I found that many consumers chose some low-cost commercial projectors on the market when considering the price factor when they set up a large-screen home theater. I don’t know. The choice has greatly violated the original intention of setting up a high-definition home theater, which is actually not desirable.
Home widescreen is king
First, the intuitive difference between a commercial projector and a home projector is the display ratio. Currently, commercial projectors still use 4:3 ratio output of traditional video signals, while home projectors use a 16:9 widescreen ratio to better match the 16:9 ratio of DVD sources. Of course, a general commercial projector can also project a 16:9 aspect ratio, but this ratio is subject to compression processing, and the projection effect is naturally not too good.
Epson, which has the core technology of LCD projectors, has three home projector products, both the entry-level 480p TW20, the mainstream 720p TW700 and the flagship 1080p TW1000, all with a 16:9 widescreen display ratio. . In terms of price, the entry-level TW20 is also very small compared to the cheapest commercial projectors on the market. Therefore, the display ratio is not suitable for home use, and it is one of the unreasonable reasons for selecting a commercial projector as a home.
Look at the contrast without looking at the brightness
Another reason why users choose a commercial projector as a home is because the brightness of the home projector is not high, and it is worried that the use of the home is not bright enough. At present, the brightness of mainstream home projectors is generally between 1200 lumens and 2000 lumens, while commercial projectors generally have brightness of more than 2000 lumens.
However, the reason why the brightness of the home projector is not high is mainly considered from the environment and projection effect of the home use, and the higher the brightness, the better. In fact, contrast is more important for home projectors than brightness. Because the higher the contrast, the richer the layering of the picture, the stronger the expressiveness of the details, in other words, it will give the user a stronger sense of presence and better visual enjoyment.
At present, the research and development around improving the contrast of home projectors has also become the focus of research and development of many powerful manufacturers. For example, Epson adopts automatic iris technology and combines new movie filter functions to greatly improve the contrast of products. For example, TW700 can achieve a contrast ratio of 10000:1. Epson recently introduced the TW1000, which uses a new crystal HD LCD panel with a contrast ratio of 12,000:1. At present, the contrast of most commercial projectors still stays at a few hundred to one.
There is no doubt that a home projector with high contrast can bring a better visual enjoyment to the user, truly making the home theater a real name. In summary, the lower contrast ratio is the second reason why choosing an entry-level commercial projector as a home is not desirable.
HD interface HD
In addition to the above reasons, the relatively scarce gap of commercial projectors can not meet the high-definition playback requirements of home users. After all, commercial projectors are mostly used for business presentations, so they are generally only equipped with interfaces such as D-sub and S-video.
In contrast, home projectors have a dedicated high-definition interface, such as Epson TW700 and TW1000 have high-definition multimedia interface HDMI (High Definition Multimedia Interface), TW1000 is the first interface equipped with HDMI 1.3 standard, can really Meet the user's high definition needs.
summary
In addition to the three points mentioned above, home projectors far exceed color commercial processing in commercial projectors. Therefore, choosing an entry-level commercial projector as a home is actually an unacceptable practice and does not achieve the home theater effect you want. For price-sensitive users, or if you want to buy a relatively cheap projector first, the Epson EMP-TW20 product is a good choice. If users want better results, There are also 720p and 1080p products such as EMP-TW700 and EMP-TW1000. All in all, when setting up a home theater, users should choose a special home projector to get better visual enjoyment.
