Therefore, Xiaobian made a comprehensive comparison between 4K home projectors and 1080P laser projectors using traditional light bulb sources in terms of brightness, color, and total cost. We use facts to tell everyone who is the current home user at this stage. The first choice.
Resolution PK
Users may not see much difference in a few tens of inches of screen. But once you project more than one hundred screens, the difference between the sharpness of 4K and 1080P can be reflected. At 4K resolution, users can see every detail of the picture, even the tiny parts of bird feathers and falling drops can be seen at a glance. This is something that 1080P does not have. If you want to enjoy the immersive viewing of the big screen, 4K is naturally the first choice. 
Total cost PK
The price of the 1080P laser projector is about 12,000. We all know that the laser light source has a service life of around 20,000 hours, which means that during this 20,000-hour service life, the cost of the 1080P laser projector is only the price of the whole machine. We Can be calculated according to 12,000 yuan. 
The 4K home projector with traditional light source, the whole price is about 8,000 yuan, and their lamp life is 5000 hours. In other words, if the 4K home projector wants to reach the service life of 20,000 hours, the user needs to replace the light bulb three times. The market price of the 4K home projector light bulb is about 500 yuan, which means that if the 4K home projector uses 20,000 hours, Users need to pay the price of the whole machine plus the price of three light bulbs, which is 9,500 yuan. 9500 yuan compared to 12,000 yuan, the overall cost of 4K home projector within 20,000 hours is about 20% lower than 1080P laser projection. 
Brightness PK
We all think that the price of 4K home projectors is too low, and the brightness of products will naturally drop significantly. The measured data shows that the ANSI brightness of these several million-grade 4K home projectors currently on the market is mostly around 1500 ANSI lumens. This kind of brightness performance shows that there are no problems with casting 100-inch screens in a dark environment, but if it is used in a bright living room, I am afraid. It is hard to find a solution. 
So although the brightness performance of the 4K home projector is lacking, the 1080P laser projector will not have much advantage, and the effect of projecting the 100-inch screen in the bright living room will not be very good either. Therefore, in this link, Xiao Bian thinks that the two should be between Zhong Zhong, it is hard to say who is better.
Summary: Through these rounds of PK I believe we have seen that 4K home projectors burst 1080P laser projection in terms of picture clarity. At the same time, the use cost of 4K home projectors in 20,000 hours is also about 20% lower than that of 1080P laser projectors, so there is no doubt that 4K home projectors using traditional light bulbs are more suitable for home users than 1080P laser projectors. Another point worth paying attention to is that the 4K source is also increasing. We will not feel that 4K is useless.

Since the end of last year, 4K home projectors have fallen below 10,000 yuan, there are already several 4K household products that are priced at around 8,000 yuan and adopt traditional bulb light sources. Such a low price drastically reduces the cost for users to experience ultra-high definition images, and accelerates the popularity of 4K in the home area. But many users hesitate at this time, worrying that such a low price will lead to the product quality is not guaranteed. There are also users who believe that this price is not as good as buying a 1080P laser projection because the laser source has better quality, longer life, and lower maintenance costs.
