Unlike the previous two years, with the increase in the distribution of UHD discs and the listing of UHD Blu-ray Disc players, more and more people are beginning to pay attention to the application of 4K projectors in home theaters. The first time I saw a 4K home projector, it was a lot of years ago. However, at that time, it was totally fun to watch, and I didn't think it was related to my home theater.
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.
Optoma arranged for the media to stay at the Beijing Lanlan Hotel, and the conference was on the first floor of the hotel.
As a result of this conference, it was mainly the old friends of Optoma who participated in the event. The organizer hoped to turn the entire event into a Party. So, when I entered the door, I saw a living DIVA.
That's right, CosPlay has been interspersed with Blizzard's Watchman Pioneer, mainly to give everyone an active atmosphere.
And behind the living DIVA, is the three protagonists of today, this is the intermediate grade UHD6600
This is the flagship projector type UHZ880. What is the difference between them?
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.
There is a pair of McRae on the left who are demonstrating the pioneer game. The cheapest UHD620 is displayed here.
This is Mr. Wei Weizhong, General Manager of Optoma China. This product launch and introduction was personally completed by the Chinese district boss.
But the first point of view, I actually do not agree. 90 and 100 inches are still too small for home theater projections. Can really experience the pixel density advantage of 4k much higher than 1080p, I think it is a big picture above 133 inches.
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.
This is the development trend of Optoma, and I bought the Optoma H30 at the end of the DVD era. The color of early Optoma projectors is yellowish reddish, and of course the current Optoma is no longer young. I witnessed the brand's growth in the home theater field once a year.
This is the three protagonists of this conference. It is very gratifying that even the cheapest UHD620 is supporting HDR.
This is the three advantages that Optoma considers itself to be. The attention is paid to the composition of the pixel lattice of the main pixel of the projector.
The above picture is about the natural advantage of monolithic DLP. Because there is no pixel alignment problem, it will get better sharpness. However, this DLP chip size is only 0.67 inches, and the ultra-small size brings cost advantages. However, on such a small chip, there is a large phase density. Theoretically, this will have a certain impact on the sharpness of the projector screen.
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.
Currently, all three projectors support 3840x2160 in physical resolution, and they are already standard home theater 4K UHD display devices.
The advantages of DLP's inherently high ANSI contrast still exist. At the same time, HDR support also pulled the contrast parameters of Optoma's DLP projectors to an unprecedentedly high level.
And, finally, on the DLP projector, I could also see the darkness of the projected screens disappearing into the background.
In general, in the past, for projectors positioned in high-end home theater users, general manufacturers do not like to use short-focus lenses or large zoom lenses.
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.
The Optoma UHD620 is the cheapest projector of this time. He pulled the price of the 4k HDR projector to within 20,000 yuan, and at the same time gave 3200 lumens of light output configuration.
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.
As the backbone of this conference, UHD660's configuration is obviously for home theater enthusiasts. The six-segment color wheel is added to meet the 100% HDTV color gamut, and the light output is smaller than the entry-level UHD620. 2300 lumens.
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.
If you want the light output level of the entertainment UHD620, and you want the UHD660's color performance, then you can also consider this laser projector UHZ880.
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.
There are three product experiences on site, but due to the complexity of the on-site light environment, one can only look at a rough level and a rough reference.
The picture above is UHZ880. When testing the JVC I once said that the noise in the HDR mode is still a bit moving, so I would like to know this UHZ880, will not make noise in the high-power light bulb mode.
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.
These pictures are the screen shots of the UHZ880 that I captured at the scene, but the problem is that the environment always plays various colors of light on the screen, so it has a greater impact on the screen.
However, from the rough perspective of my scene, UHZ880's sharpness, three-dimensionality and color, including the performance of the black level, make me very much want to flee home and play well.
The UHD660 is much better paid, and its display is an independent, almost black home theater space.
However, the staff mistakenly set the player's proportions, so he pulled a horse face long. If we do not take into account the fact that there are many people at the press conference and the workload is really big, I really want to send a bad review.
However, in terms of the three-dimensional and black level of the screens I saw at the time, I think there are more surprises.
As for the third UHD620, the cheapest entertainment machine, this station has been watching the pioneer.
This game is more fun, but it can not reflect the 4K resolution and HDR technology of the projector. So, here is mainly for the active atmosphere of the scene. And, those four handsome CosPlay guys added this scene and they did achieve their goals.
Overall, I think the conference of Optoma was very successful. The main reason is that these three products all have a very clear positioning. They all gave me a strong interest in trying.
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.
On the way out of the press conference to the airport, a sign was seen at the entrance of the hotel.
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.
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.
