All million contrasts start! Optoma 4K HDR home ultra high-definition projector interpretation
After all, in the era of Sony VW1000ES, very few people will buy 150,000 yuan to buy a projector that has no source at all.
However, since last year, the situation has changed - the price of 4K projectors is no longer so high, and new standards such as HDR technology and BT2020 color gamut have begun to be supported.
A few days ago, I went to Beijing and participated in the conference of the latest 4K projector from Optoma.
I didn't want to do business on business trips. After two days of rest, I would like to chat with you briefly today.






I do not know either. Because as the old oil stick in the circle, I never preview the conference content. Just like when you were studying in the same year, you never read your homework. On the day of the conference, it was the college entrance examination. As a school slag, I would like to have a snack.




Especially when it is more than 180 inches, the perception of the 1080p Blu-ray is just as rough as the 90-inch screen in the DVD era. The 4k is a must-have for home theaters.




However, the theory goes back to the theory and how it looks and feels, and it really needs more experience to answer it later. After all, the technology in all aspects of home theater projectors is improving.


And, finally, on the DLP projector, I could also see the darkness of the projected screens disappearing into the background.

However, after 4k arrives, even if you watch a 150-inch screen at 4 meters, you will not feel that the screen is not enough. As a result, Optoma's products, even the most high-end laser light source machine, are equipped with a 1.6x zoom lens. This configuration is scientific and reasonable.

Its goal is simple - let you use a minimum of money, give you a high-brightness projector that can support a larger picture. At the same time, the Optoma UHD620 also achieved a contrast ratio of 1,000,000:1.
However, please note that if the light output is too high, then the color gamut will shrink, so the wide color gamut visit given by this product is 97% coverage.
At the same time, this projector does not use a six-segment color wheel. This must be said to be the drawback of the entry-level machine.

However, the light output of 2300 lumens still has advantages compared with rivals whose LCD camp is about 2,000 lumens in the same price range. At the same time, the price of 26,990 yuan is indeed the most lethal.
And, the contrast of this product is over a million levels, and the official parameter is 1,200,000:1.

The UHZ880's light output is 3,000 lumens and the contrast ratio is as high as 2,000,000:1. In terms of parameters, this has exceeded the 2000 lumen output of the JVC DLA-X9900BC projector and a contrast ratio of 1,600,000:1.
UHZ880 is quoted by the media as 60,000 yuan, while the JVC DLA-X9900BC is 79,000 yuan.
UHZ880 also has the life advantages of laser sources, while JVC DLA-X9900BC can provide color performance far exceeding 100% HDTV color gamut with the support of three-chip LCD technology. To know that under the BT2020 standard, this is also very valuable.
For me, both products are the machines I want to buy. Before the purchase, I will try to borrow it and try it out.


However, because the site is too noisy, I have no way to experience the UHZ880's noise control level.
However, when I was at dinner, I inquired about the general manager. He vaguely remembered that the high-power UHZ880 only had a noise level of 23dB. He said that this has a certain relationship with the application of laser light sources.
What is the concept of 23dB? Simply put, you can think that there is no noise at all.
However, I am a bit skeptical about the accuracy of this data. After I get the test machine, I must try it out.
For users who purchased the UHZ880, the noise of the projector must be a big enemy—because the sound of this type of user is mostly not a bargain. If it is affected by the noise of the projector or amplifier, it is more upsetting.





However, in terms of the three-dimensional and black level of the screens I saw at the time, I think there are more surprises.




I have participated in countless projector conferences, and many times except for flagship products, most of the time I have little interest in entry-level products.
This time, among the three products, there was no model with a particularly shrinking performance. This made me wonder how the performance difference between them and the price difference was actually higher.

Suddenly remembered, even the most expensive UHZ880 among the products is actually nothing. The biggest pain in playing home theater is that you have to provide them with a space that is really not cheap now.
