Choice of family projection

As a display device, projection can replace TV.

Using projection and TV at the same price has its advantages and disadvantages. I am a projector, so I will talk about projection. Common projection is divided into DLP, LCD and so on. And so-called commercial, educational and home computers. In my personal understanding, the business machine is characterized by portability, the education machine is characterized by good heat dissipation and dust prevention, and the home machine is characterized by high definition.

If you plan to use your home, you should choose home projector, but now the price in home projector is generally higher, and the cost of his consumables-light bulbs (which will be mentioned below) is higher, which is not easy for ordinary people to accept. The problems brought by the portable and compact business machine are poor heat dissipation and high price. Therefore, some people choose to buy educational machines. The price of the education machine is relatively moderate, but it is bigger than the business machine, and there is no high-definition picture. For the picture quality effect, you can go to the store to have a look. For non-professional customers, you generally can't see the difference between high-definition and ordinary projection.

Generally speaking, the life of the light-emitting device-light bulb in the projector is 2000-4000 hours. If well maintained, the light bulb will not break down during this time period, but the brightness will become darker than that of the new machine. You can calculate your usage time.

I hope you buy a projector just to watch movies, but watching TV is not cost-effective.

By the way, I recommend two models for you. The price of Hitachi HCP-900X (educational machine) is about 6000 yuan, and that of Sharp Z3 100A (home machine) is about 8000 yuan.

Finally, say a word or two more. If you buy a projection, you must go to a regular merchant to buy branded goods, otherwise the Brotherhood will regret it. I wish you a happy shopping.
