When the laser hits 4K UHD! Optoma UHZ880 super detailed comparison report
The first time I saw the UHZ880 was at the Optoma 4K conference earlier this year.
At that time, the perception of this machine remained on the UHD660's light source upgrade product.
The scene is a project sample, the projection screen is not large, I just think the color looks okay.
In terms of the parameters announced at the press conference at that time, my understanding of him was more focused on the application of laser light sources and the support of 3D (at the time the 4k DLP machines did not have any support for 3D).
In fact, this is a very abstract thing - it's like someone told you that a dish is made of rare ingredients, but based on these you can hardly imagine what the dish is like into the mouth.
Optoma UHZ880 was not listed after the conference, but UHD660 went public.
The projectors I got at that time were really rich. However, compared with the products at the time, the JVC DLA-x6900 was significantly better than the OHD660.
Regardless of the brightness, contrast, color, three-dimensional feeling, the fluency of the picture, Optoma UHD660 completely unable to compete with the JVC 6900.
But think about this as normal, JVC DLA-x6900 is much more expensive than UHD660. The UHD660 is not entirely without advantages - cheaper, and basically sitting next to the projector watching movies, can not hear any running noise.
In fact, after trying out a few machines, I had a very strong interest in JVC's higher level DLA-X9900. At the same time, in the subconscious I want to know how much the Optoma UHZ880 is worse than the JVC DLA-X9900?
As a result, when I had two projectors at the same time and distributed good color corrections and then watched for ten minutes, I had the feeling of opening this article. I once again realized that I didn't use random guessing in my probationary career.
In fact, if you look at the Optoma UHZ880 and JVC DLA-X9900 at the same time, you will understand what is actually available HDR and just let your technology take a look at the difference between HDR. Optoma UHZ880 is too strong.
The gap between Optoma UHZ880 and JVC DLA-X9900 is far greater than the gap between the JVC DLA-X6900 and Optoma UHD660...
Looking at the JVC DLA-X9900 alone, you will feel that this product film is very good, the color is not bad. But if you compare it with Optoma UHZ880, you will find that in addition to JVC's natural fluency in addition to Lcos's technology, the others lose and lose badly...
Well, let's start with the details of this experience.
Optoma UHZ880
The old rules, take a look at some of the official information.
In fact, after I tried this machine, I noticed that the official has suggested that the new light source will improve the color performance, and the contrast of this product has actually reached the level of 2 million:1.
Above I have marked out some of the main features of this projector, the official price of Optoma UHZ880 is 59999.
The appearance of the Optoma UHZ880 is basically the same as that of the UHD660.
No keys around the body
The VGA interface behind me is totally incomprehensible, as a high-end projector will actually be equipped with a VGA interface that home-use projectors have given up. It is difficult to find a PC or laptop with a VGA port.
And if you want to watch UHD Blu-ray Disc, please remember to connect only to HDMI2 interface, because only the 2nd interface supports HDCP2.2 standard.
Fingerprint collector, but fortunately the general projector will not touch it.
All the buttons and controls are hidden inside this cover.
The Optoma UHD660's buttons are on the side.
The adjustment button on the body surface is actually very simple.
UHZ880 lens up and down translation range, very small. However, it is better to have this function than nothing!
The focus ring is on the lens
Monolithic DLP is easier to identify when focusing, and with UHZ880's screen debug auxiliary display, the debugging screen is still relatively easy.
Experience the Optoma UHZ880
All projector experience starts from the moment you press the remote control. The high-end machine is not equipped with a backlight remote control. But before the Optoma's dazzling blue backlight, almost all media spit.
Happily, Optoma finally changed this light to white. However, I think it is still too bright.
I would like to ask Optoma engineers to use their brains to think carefully. Who would like to use a small torch in their eyes in an all-black dark room?
Let's take a look at Optoma's menu first, this is the show settings page
This is the setting of the built-in speaker. At the time of the last deployment, I asked why this grade positioning machine will have a built-in speaker.
According to official officials, this is because some people will always pick faults. Why do people think that projectors have built-in speakers and Optoma does not?
The person I want to talk about is, does Otto Code really think that the “total person†who asks this question is to purchase your flagship projector user?
At least in the JVC, Sony, SIM, Epson brands, I really did not see which flagship product to install this sound bad, and users will not use the speaker.
Here are some settings about the projector hardware itself
Here is the function for accessing intelligent control
This page is the basic information of the signal being played, including the resolution, refresh rate and so on.
Well, start the highlights and show the settings. The first item in the display settings of almost all projectors is the display mode.
In the 1080p era, only one theater mode is often required. Basically, it can correspond to all usage requirements. But in the era of UHD, this is not the case.
Because the UHD era uses a new HDR high dynamic range source, the UHD source must correspond to the HDR mode. However, if you are not playing UHD sources, the HDR mode of the UHZ880 will not be activated.
Previous UHD projectors, whether it be JVC, ACER, BenQ, or Optoma, we have found this problem - when you play HDR-capable UHD sources, turn off the HDR mode, and the screen is distorted by the color of the candle. It will become very strange and totally impossible to watch. This is because BT2020 and HDR are played incorrectly.
However, when I tried the UHZ880, I found that the problem was solved by the UHZ880. How to do it? To understand this, first of all know how UHZ880 open HDR display mode.
To open the HDR mode of Optoma UHZ880, you have to meet two conditions:
First: Play source is UHD player, play UHD source, and UHZ880 is connected to it using HDMI2
Second: In the dynamic range setting in the UHZ880 display setting, the HDR mode is set to ON
After HDR is set to on, there are four modes that can be switched. We will wait for this.
Everyone notices that when the HDR display mode of the projector is enabled, the projector's information bar will show the source color format of BT.2020 and HDR.
If at this time, HDR in the dynamic range is turned off, other projectors will use the SDR color format to reproduce the HDR source, so the color is naturally distorted.
However, I have to say UHZ880 is smart.
UHZ880 will tell the video player - buddy, I switched to SDR mode, and the trouble you give the signal also switched to BT.709 and SDR mode.
At this time, the screen will change colors in a mess, and then you can see the normal color SDR screen.
The display code continues to pull down, and the second page will come out. The adjustment of Gamma and color are all here.
Gamma has six options and cannot be customized
PureEngine is a trick for Optoma, but I usually get the machine. The first action is to enter the menu and turn off the PureMotion responsible for motion compensation.
Because I really can't accept the projector to generate a picture that was not originally in the film source, to make the motion picture more smooth.
My eyes will accurately confirm those pictures and make me feel good...
On the other hand, with the current dynamic compensation of projectors, error frames have become less and less. Some people can not accept the source of the original trail, you can open up and try it.
Color temperature and advanced color management, under the color settings menu.
Before the fans who purchased UHZ880 responded, the picture of this projector was a bit bluish. After I corrected it with the instrument, his perception was accurate anyway.
Well, here I would like to give the manufacturer a response to the small problems of the Optoma UHZ880 and the UHD660 and 620 - brightness, contrast, and the stepping of each option in the RGB adjustment is really too great.
For example, to adjust the brightness, for example, we open a picture of Hivicast. The ideal course is that the levels are clearly separated and can be as dark as possible.
If it is a JVC or Sony, you can adjust the brightness value little by little, and then observe the slow change of the picture.
The brightness adjustment of an Optoma is that if he adjusts to exactly 1, then it is very likely that the picture will turn grey as a whole when it is tuned to 2, and it is all dark and it will not be able to see anything.
That's right, the Ottoman's brightness, contrast, and RGB adjustments all have this problem. His adjustments for each level change too much, even if the step is not 1, but it is 0.5, which will be fine. Use a lot.
This is not a problem with the hardware performance of the product. However, this setting has a huge impact on the user's ultimate experience in the product.
Screen capture and characteristics analysis
In fact, in the process of debugging the machine with a color tone meter, I discovered that the UHZ880 has a rare advantage in UHD projectors within 100,000 yuan.
This machine was still able to measure 43 ftl (100 ire) under the screen on my perforated screen with a 120-inch 1.4-inch screen after debugging.
For the same level of opponents, he provided a full level of brightness, nearly doubled.
This is not really important for 1080p SDR video, but it is just too important for UHD HDR video.
The picture above is a fragment of the HDR performance that I often use to test the projector, from "Billy Lynn's intermission," and this section shows the sunlight in the Middle East at noon.
Why must it be noon? Everyone pays attention to the shadow of this fragment to make sure that the sun is basically on top of the head.
Everyone recalls that in the most ferocious period of summer sunshine, the sun is not basking on the ground.
The focus of this paragraph is to restore this tanned scene.
The HDR's high dynamic performance is very good at the ultra-high UHZ880 and contrast ratio of 2 million:1. And, the screen shot of this scene has no way to truly restore my true feelings.
The problem is that in the big sun you use the SLR to shoot objects outdoors - if you set the metering point on the front hood of the Hummer, the hood can be photographed clearly, but the overall picture will be darker than it actually is. ;
However, if the photo of the photometry spot is surrounded by a shadow or on the ground, the hood must be overexposed.
Therefore, the screen shot above cannot actually reflect my perception. In terms of actual perception, the contrast between the video and the video will be more intense.
For the UHD projectors I reviewed before, I proposed that when they responded to this HDR video presentation, they could barely feel the difference between HDR and SDR.
The brightness of the UHZ880 is really HDR.
The figure above shows the SDR and HDR video formats. Everyone can see that the SDR video actually only reflects a small amount of real-world color.
While HDR has a greater dynamic range, he is capable of developing objects that are very bright and very dark, but at the same time it imposes requirements on the brightness and contrast of the display device.
Simply put, although HDR allows you to see colors in very bright and very dark scenes, the prerequisite is that your monitor can reproduce that level of brightness.
Because this UHZ880 uses a laser light source, he controls the light source power more precisely. He can adjust from 50% to 100% in 5 steps.
The figure above is a comparison chart of 100% power and 55% power.
Obviously, when the brightness of the light source is only enabled at 55%, it is not enough to reflect the scene of the exposure, so the weather of the big sun has become cloudy.
Even in HDR mode, Optoma offers four options for the dynamic range of HDR: movie, standard, bright and detail enhancement.
However, after I took a picture and looked at the whole picture, I did not find any difference between these modes.
Zooming in on the picture to compare the details under the 100% mode is a bit of a difference, but I think it's really a bit of a difference. Which is better to use, I think it is still to see everyone's own taste.
The overall picture is bright and transparent, and the details and texture of the weapon are very real. At the same time, the dark place can still be black.
This M4 is completely dealt with under the backlight, still can see the texture and details above. If you have recently played around the world's "eat chicken" game, you will be able to recognize that this is an all-inclusive M4, Class II helmet, and Class II body armor.
In addition to the performance of ultra-high-brightness scenes, HDR's shading in dark scenes has a very strong advantage over SDR.
Like the map above, it can go black but it is clearly structured. Regardless of whether the scene is bright or dark, there are still true colors.
The front and back scenes are very rich in color, and everyone notices that Billy's face is over-colored.
In this scene, the color and details of Billy's eyeball really surpass any machine at this price point.
After the UHD disc was tested, the next was a 4k SDR video downloaded from the Internet.
If you watch SDR video and still use 100% of the light source power on my 120-inch screen, then the look and feel is very similar to that in the TV market. The picture is bright and sharp, but it is too dazzling.
This is completely different from HDR mode. SDR mode is basically no way to consume this powerful light output, and this is not the projector's perception.
After reducing the power of the laser source to 50%, I got a more structured and better viewing experience.
This is the sense of watching movies brought by the projector, not the glare of the LCD TV.
In fact, the projector is suitable for viewing in an all-black environment, and the television is an active light source display device. As long as you are in a dark environment, even if the brightness is very low, but the eye fatigue program will still be much higher than the projection screen.
Three-dimensional, sharp, colorful and over-colored.
This is a 4k video from Changhong TV, shot by friends West Feng in Chengdu.
At the time, Xi Feng also said that this model is not pretty enough
The routines of the 4K TV promos are all large color contrasts, and the rich texture and texture reflect the texture of the object itself.
The last test was "Avatar," which everyone is familiar with. Officially stated that this product is to support 3D, and then I put a magical scene into the 3D Blu-ray disc.
If the projector does not support 3D, the disc will pop up at the very beginning, telling you to update your device that supports 3D, and try again.
And if the projector supports 3D, then you will see the menu and appear as a ghost.
However, the UHZ880 did start playing in 3D, but the menu was not ghosted.
Later, I challenged the manufacturer's technical staff. The answer given by Optoma is that this product supports PC 3D and does not support Blu-ray 3D, so this magical situation will occur.
In other words, UHZ880's 3D does not have much practicality, but it's no wonder that Optoma.
Because of this, TI has no 4k chip that can support Blu-ray 3D.
If your display device has high contrast and strong color reproduction, then the CG characters in this movie will have the feeling of a real doll and their skin will have a strong sense of solidity.
However, the source of this SDR will still be very dazzling if the light source is used at 100%.
Using the light source power to 60%, the overall impression is more movie-like
At the lowest 50%, the picture shows a better sense of film. For my 120-inch 1.4-inch screen, this brightness is the most appropriate.
The color saturation is still high, some drop down, full of sense of the film.
If it is not for personal use, I can hardly imagine the UHZ880 and UHD660 have such a big difference in color and brightness. The difference in quality displayed by them is far greater than the price gap.
Written at the end:
Well, the advantage of this machine is in the brightness, quality, color and life of the light source, and in the end I also talk about his shortcomings.
In addition to the previously mentioned brightness, contrast, and other adjustment step settings are too rough, UHZ880 itself is still some monolithic DLP projector born flaws - this includes still has a very slight rainbow effect, and JVC and Sony In contrast, the smoothness of the dynamic picture is still a little bit different.
But I have to say that UHZ880 has no rival among the home UHD projectors within 100,000 yuan, in terms of quality performance itself.
In fact, I think that the price of 59,990 yuan for the actual performance of the UHZ880, this is obviously low pricing. If this machine is SIM2, selling 15W I think it should be very easy.
And the most important thing is that you really have to cast 150 or 180-inch large screens, UHZ880 is also the tens of thousands of dollars UHD home machine, the most worth considering products.
However, the problem has arisen, if the Optoma price 80,000 yuan, then the brand Optoma can not afford this price. Now with a price of 59,990 yuan, he has a very high price/performance ratio, but I also don't think this product is easy to sell.
Because people who do not understand will always know more than others, there will always be people who buy something for the brand. However, I came to hope that if your budget is to buy a UHD projector within 100,000 yuan, then it is best to look at the UHZ880's real machine, which is good for you.
