Shulou(Shulou.com)11/24 Report--

In May last year, Hisense Vidda released the world's first 4K tricolor laser projection C1, which not only took the lead in carrying the industry-leading tricolor laser technology at the price of 6999 yuan, but also had excellent ultra-high color gamut, color accuracy and high brightness performance. I was extremely impressed.

In less than a year, the Vidda projector family once again ushered in a new product-Vidda C1S. As an upgrade to C1, Vidda C1S has brought a full range of upgrades, including eight key upgrades, including an increase in brightness to 1600ANSI lumen, a gamut increase to 110% BT.2020, a contrast increase to 1600 BT.2020, and speckle elimination technology, while the initial price remains below 10,000 yuan-7299 yuan.

Vidda C1S next, CTOnews.com will bring readers the actual experience of this product.

Before evaluating Vidda C1S, it is still necessary for CTOnews.com to share with readers about several mainstream "projection" technology routes, so as to better help readers choose and purchase projector products.

The core of projector products is the light source, and the current home projector light source is divided into three major routes: traditional light bulb machine, LED light source and laser light source.

The advantages of the traditional light bulb machine are low cost, high brightness, but short service life, need to change the light bulb regularly, and the later use cost is high. This kind of projector is commonly used in our classroom when we were young.

LED light source technology now occupies the absolute market mainstream, compared with the traditional light bulb machine, LED light source has a long life, compact size and better color. However, there are also some problems, such as low brightness, high thermal power consumption, high noise and so on.

So, by comparison, the advantages of laser light source are very obvious-longer service life, slower light decay, pure picture color, higher picture brightness and low power consumption. It can be said that laser light source combines the advantages of light bulb and LED lamp.

The only disadvantage is that the cost is high and the price is high.

Of course, the author will not come to a conclusion about which of the three projection techniques is good or bad. after all, there are no inappropriate products, only inappropriate prices.

If you have a large budget and have more stringent requirements for the color, brightness, and display of the projector, then the laser projector is perfect for you.

However, laser projectors are also divided into two technical routes-monochromatic laser and tricolor laser.

The monochromatic laser has only one blue laser light source, and the red, green and blue tricolor is realized by "bombarding" the color wheel phosphor. After projected on the DMD chip, the projection display image is finally formed.

Of course, the disadvantages of monochromatic laser are also obvious. as a relative "compromise" between "high cost and practicality", red and green in monochromatic laser technology have not reached the ideal state in terms of color purity. there is still room for improvement in picture quality.

The tricolor laser uses red, green and blue laser as the light source, and the fluorescent color wheel component is cancelled in the structure, so the color performance is more excellent.

Trichromatic laser because the laser is the light source with the highest color purity in the world, the tricolor laser can restore the color closest to the real world after mixing and blending. This is also the biggest advantage of trichromatic laser technology over existing display technologies such as LED.

As a projector product of tricolor laser technology, Hisense Vidda C1S is equipped with Hisense LPU tricolor laser engine, which greatly improves the color performance of the image, with a color gamut of 110 BT.2020 and a color accuracy of Δ E ≈ 0.9.

Not only that, Hisense LPU trichromatic laser engine contains four "cool techs", in which the microcrystal anti-noise algorithm deeply optimizes the flip timing of DLP micromirror, which can effectively suppress noise up to 99.9%; while the achromatic effect of OPT super achromatic technology can reach 98%, realizing no ghosting of the picture; and integral chain smoothing integration technology can improve the brightness uniformity of the picture to 97%. In terms of speckle elimination technology, Hisense has the largest number of 102patents in the world, so the new multi-dimensional dynamic speckle solution carried by Vidda C1S takes the lead in realizing the "human eye weakness" of speckles in the industry.

First, the measured brightness is a very important parameter of the projector. Only with enough brightness can the rich and delicate colors be displayed.

Vidda C1S claims to have measured brightness of 1600 ANSI lumens, and the brightness measured by the new standard is also 1600CVIA lumens.

It needs to be emphasized that the brightness here is the "measured" brightness.

You know, in the whole projector industry, due to the lack of strict brightness measurement standards, and even a variety of nominal methods, many users have bought some projector products with the nominal "high brightness". However, when using it, it is found that it is not as bright as imagined, such as this kind of logo confusion or even false mark phenomenon is very common.

However, with the implementation of the new CVIA standard, the illusion of projector brightness in the future may become a thing of the past.

In fact, last year's release of Vidda C1 emphasized that it was true, and the measured results were indeed the same-the official nominal brightness was 1350 ANSI,CTOnews.com and measured 1454 ANSI, even more than 100 ANSI higher than the official standard.

Next, CTOnews.com measured the brightness of Vidda C1S.

It's the same old way:

In accordance with the national standard 32028 document issued in 2015.

With the help of illuminance meter, the brightness of 9 white spots of 9 grid was tested, added and divided by 9, and the average value was obtained and multiplied by the projected area.

Need to note that different environments, different walls, the test results are different, CTOnews.com here as much as possible to restore the use of ordinary consumers, the measured data is only for verification and reference.

The screenshot of GB 32028 file we chose the distance of 2.7m. At this time, the projection size is just 100in (diagonal) and the projection area is 2.76m ². The luminance data of these 9 points are tested respectively, as follows:

Note: due to ultra-high color gamut, photos taken by mobile phone will be red. The above picture is for reference only. It does not represent the average brightness of Vidda C1S: (604 "644" 592 "620" 647 "611" 619 "645" 603) / 9 ≈ 620.5

Measured brightness = 620.5 × 2.76 ≈ 1712.73

After measurement, the Vidda C1S has a measured brightness of 1712.73 ANSI lumens, which exceeds the official claimed brightness of 1600 ANSI.

Obviously, the Vidda C1S inherits the glorious tradition of its predecessors, and its brightness is not false, and even the measured data exceed the official data, which can be said to be absolutely conscientious.

According to the industry consensus, in a pure dark environment, 1600 ANSI lumens is enough to meet the projection of 150 inches; from this point of view, the 1712 ANSI of Vidda C1S is sufficient to meet the needs of users.

Some people may ask, does it mean that with Vidda C1S, you can watch at home without curtains during the day?

Here I need to give a clear reply, including Vidda C1S, any current home projector products, in fact, can not be used to watch scenes without curtains during the day, want to use projection instead of TV watching during the day, in fact, it will not work.

For example, at noon, when the sun shines directly on the living room, when the curtains are opened, the projected picture will still "fade", the contrast will decrease significantly, and the picture seems to be splashed with a layer of white paint, and no projector can understand it in this scene. Therefore, we want the projector to have a better display effect and create a dark environment as much as possible.

Friends who have the idea of "watching projection without drawing curtains during the day" actually hope to completely replace LCD TV with projection. But the author believes that this idea is actually a misunderstanding, projection and television are actually complementary, the two provide a completely different viewing experience and atmosphere. We buy projector products because we want to experience the cinema-like atmosphere as much as possible, but the cinema also provides a pure dark environment, right?

Second, the picture quality measured Vidda C1S is equipped with Hisense LPU tricolor laser engine and 0.47 "DMD micromirror chip with 4K ultra high definition resolution. Vidda C1S is upgraded in multi-dimensional areas such as speckle suppression and color aberration control, including color gamut of 110 BT.2020 and color accuracy of Δ E ≈ 0.9.

It should also be emphasized that the Vidda C1S color gamut standard is BT.2020,BT.2020 gamut range far beyond our common Adobe RGB, SRGB, closer to the maximum color range that the human eye can recognize.

Through conversion, the color gamut of 110% BT.2020 is equivalent to 152% DCI P3 and 149% NTSC, which has far exceeded that of mainstream LCD TVs and OLED TVs.

Next, let's take a look at the picture quality of Vidda C1S through 4K video.

CTOnews.com Note:

Once again, it should be noted that due to the ultra-high color gamut of Vidda C1S, the pictures taken directly with digital cameras and mobile phones are obviously red (the actual look and feel is normal), so the picture below is for reference only.

In terms of actual experience, the color of the picture presented by Vidda C1S is quite excellent, the look and feel is very full, pure, and does not turn gray.

With the help of dimensional dynamic speckle elimination solution, Vidda C1S also avoids the "speckle" problem caused by laser coherence as much as possible, and the picture looks more transparent and clear.

Even, in a sufficiently dark environment, the picture presented by the Vidda C1S will feel like a professional color display hanging on the wall, rather than a "projection". This effect can really be said to be "unforgettable".

Then through the 4K test chart to see the basic picture quality performance of Vidda C1S.

As shown in the following figure, in the 4K resolution test, the smallest text in the left English area can also be displayed clearly, and the areas pointed to by the blue arrow (1080p) and the red arrow (4K) can be fully displayed, and the text is not blurred, indicating that Vidda C1 has reached the 4K resolution standard.

It should be noted that the 4K resolution of Vidda C1S is also achieved by XPR jitter technology, which is commonly known as "dithering 4K".

Of course, do not complain, the physical resolution of the projector depends on the resolution of the core imaging chip, pure physical output of 4K, then the area of the DMD chip is larger, and the price is "sky-high".

So, "shake 4K" itself is also a choice of both effect and low cost, and in terms of practical experience, the 4K display effect of Vidda C1S is already quite outstanding.

In terms of grayscale display, Vidda C1S shows 256grayscale images. The transition from black to white grayscale is very delicate and natural.

In the color performance test, Vidda C1S has a very good color treatment for dark areas such as gray, brown and black, showing a uniform and soft transition.

At the same time, Vidda C1S is quite in place in the reduction and treatment of red, blue, green, white, black and other colors, after all, it is a tricolor laser, and the technical advantage lies here.

Generally speaking, if you have high requirements for picture quality, then Vidda C1S will definitely meet your needs, and its color display will definitely give you a thumbs up.

Third, the appearance design compared with the previous generation C1, the appearance of Vidda C1S does not change too much, still uses a relatively "square" shape, the fuselage is dark gray, without too much line modification, and the shape of the integrated metal fuselage is quite simple, with a strong versatile attribute.

The front of the Vidda C1S is treated by a metal wire drawing process and a circular treatment is done around the projection lens, while at the bottom is a large strip heat dissipation hole.

There is also a camera and ToF sensor on both sides of the projection lens for auto-focus, automatic obstacle avoidance, screen entry, and so on.

At the top of the equipment are the buttons for turning on the product, volume, and so on.

A large area of hollowed-out design is used on the side to ensure better heat dissipation and sound release of the product, with a Vidda carving logo on the back and a row of concave interfaces below.

The interface includes DC*1,HDMI2.0*2,USB2.0*2, optical fiber * 1, headset * 1, network port * 1.

In addition, in the installation mode, Vidda C1S is supporting table forward projection, hoisting forward projection, hoisting rear projection, table rear projection and so on, which can meet the needs of different scenarios.

The weight of Vidda C1S is 4.8kg, although it is heavy, adults can still move it, it has certain portable properties, and the length of the power cord is up to 3m, which meets the needs of different indoor environments and outdoor camping scenarios.

4. In terms of measured sound effects, Vidda and audio brand JBL have customized a HiFi sound system for C1s, including 2x10W speakers, MAX sound pressure up to 90+dB, and carefully trained by Harman Acoustics team, it also supports Dolby + DTS double decoding, DTS Virtual X 360 °surround sound effects + Dolby DAP sound effects + Viper sound effects.

Playing teacher Cai Qin's "Ferry" simple experience, Vidda C1S low frequency performance is very strong and flexible, in the middle and high frequency strings and vocal parts, Vidda C1S performance is also in place, the voice is round, instrumental music is delicate, the overall performance is comparable to this price.

And, because the shape of the projector itself is very different from the TV, the TV is often fixed in a certain area, and the sound is facing a fixed direction, while the projector itself is more like a speaker, the sound is wide in all directions, so in the experience, Vidda C1S has a very obvious sense of presence, which adds a lot to the experience.

Second, the Vidda C1S can indeed be turned into an intelligent speaker, which supports the function of listening to music on the screen and can enjoy music without throwing the screen.

Fifth, the comprehensive experience system, Vidda C1S is based on Android deeply customized JUUI7.0, system UI design, interaction logic is basically the same as Hisense TV, UI design uses the common UI design language of large screen TV, the home page provides my, cable TV, VIP, TV series, movies, variety, children, time flow, education, music and so on, basically covering all aspects of life and entertainment.

In the basic hardware, Vidda C1S is equipped with MTK9669 high-end chip, 4GB running memory, 64GB storage, support WiFi5 and Bluetooth 5.0, support near-field + far-field voice commands, and use the new iFLYTEK algorithm to accurately pick up sound. For gamers, the Vidda C1S also supports ultra-high refresh rates for full-channel 240Hz in 1080p full HD mode, with latency as low as 12ms.

Like Vidda C1, Vidda C1S also supports global autofocus, intelligent trapezoidal correction, automatic obstacle avoidance and automatic screen entry. In AI picture correction, Vidda C1S also adds a dToF to achieve non-inductive focus and make the correction experience more comfortable.

Vidda C1S also adds a bilateral entry function, which is different from the traditional projector which needs to identify the upper and lower left and right sides to enter the screen, Vidda C1S only needs to identify the upper and lower sides to enter the screen, which is more intelligent.

After all, the projection line has a relatively "portable" attribute, which may be used in the living room today, in the bedroom tomorrow, or even occasionally camping and having a picnic.

In the face of these different projection environments, the traditional projector always takes a long time to place a reasonable position, either high or low, left or right, which is time-consuming and laborious, and even discourages the enthusiasm of use.

With Vidda C1S, a series of intelligent functions such as non-inductive focus, intelligent trapezoid correction, automatic obstacle avoidance, automatic screen entry and so on, give great points to the experience.

Take automatic obstacle avoidance as an example, when there are obstacles in the area where we cast the screen, Vidda C1S can automatically identify obstacles and put the picture in a complete and unblocked area.

For example, intelligent trapezoid correction, in many scenes, the projector needs to be placed obliquely on the desktop, and Vidda C1S has a correction range of ±40 degrees, so even if the projector is not square, you can easily enjoy the large screen without manual adjustment.

Vidda C1S also has multiple advantages in eye protection experience, including TUV low blue eye protection certification, "0" harmful blue light, avoiding harmful blue light bands, supporting large screen diffuse reflection eye protection, and global eye protection, when the ToF sensor on the front of the device detects human activity, it will automatically reduce the light and further reduce the irritation of the projection light source to the human eye.

Written in the end: after a period of experience, the Vidda C1S 4K tricolor laser projector gives the author the most profound item, two words to describe the most specific-professional.

In fact, the previous generation of Vidda C1 picture quality performance and comprehensive experience is excellent enough, but Vidda is obviously not satisfied, this advantage in the new Vidda C1S further magnified, whether it is the color presentation, or audio tuning, Vidda C1S 4K tricolor laser projector is worthy of the word "professional", and even compared with high-end OLED TV, Vidda C1S also has full competitiveness.

With the blessing of tricolor projection technology, Vidda C1S has an extremely strong color picture quality performance, which is unforgettable, so if you need a projector product that is comparable to the laser cinema experience, Vidda C1S must be your choice.
