In order to verify the impact of the resolution on the viewing effect, I self-queried some information. The answer is that resolution is not the only factor that affects clarity:
For example, the 720P 3DLP InFocus SP777 projector can kill 2K home consoles in seconds, and the 8MP iphone camera is often better than a lot of 13MP camera. The final visual clarity of the projector is also related to the brightness, contrast, drive circuitry, optical resolution of the light engine, the environment in use, the screen shot, the viewing distance, and the like.
800p is not 1080p?
In this regard, I want to use a metaphor to describe. 1080p is like a beautifully printed (Full HD) book, 800p is like a general printing (HD) book, under the dimming effect, no matter which one will not see, brightness is enough, we can both books Clearly see. Assume that the use of a transparent matte film to prevent the surface of the book is definitely blurred, which in fact reduces the contrast. This means that for the current stage of smart LED projectors, the final visual clarity is determined by brightness and contrast. Increase the brightness and contrast to get a clearer picture.
720p source is still the mainstream:
At present, whether it is iQiyi, Youku, Leshi or Sohu, the general definition is divided into automatic, standard definition, high definition, super clear, and VIP1080p, while 720p is the default super clear source, and 1080p cannot be selected at any time. Even if you choose, you have to consider the smoothness of the video and the support of the network.
In fact, the final decision on whether or not you choose a projector is also a crucial factor, which is cost-effective. I took a look at the crowdfunding page and technical parameters of this projector in detail. Overall, the price/performance ratio of this projector is still very obvious. It is estimated that this is part of the reason why so many consumers support this product.
Finally, I would like to share with you, if it is you, you will choose a smart projection as a TV alternative?
