Key points for purchasing projectors
Here is a summary of the key points for purchasing projectors. You can save it and choose it according to the key points.
light source, brightness, contrast ratio, color, resolution, CPU, RAM/ROM, intelligence, voice control, sound
It should be emphasized that you should never blindly place an order just because the picture parameters of the projector are excellent, or buy it directly just because the system is turned on without advertisements. In the process of purchasing a projector, the most important aspects such as picture, system and sound are indispensable. As long as there is a problem with the experience of sound, picture or system, the final result is that the projector effect is not good.
In-depth evaluation of AOC EliteVision laser projector
Appearance: the collision of retro and technological sense
The AOC EliteVision laser projector adopts a dark gray double splicing design as a whole. The upper part is made of aviation aluminum, and the lower part is made of high-end audio cloth. The lens has a large gold ring design and a TOF+CMOS sensor camera, a CD texture effect on the side audio, dual 12W large-caliber strong magnetic speakers + dual wide-body passive diaphragms, and the overall structure is similar to HIFI audio. The entire body design language is in the overall modern technological beauty, revealing a sense of retro beauty.
The back interface of the body is complete. 1 HDMI2.1 interface and 1 HDMI2.0 interface, the transmission bandwidth has been greatly increased from 18GBps to 48Gbps. It is precisely because of the use of the HDMI2.1 interface that the AOC smart projector EliteVision can support 240Hz transmission, which is better than the 120Hz transmission of most other projectors at the same price. In addition, in addition to the two HDMI interfaces, there are 2 USB, 1 S/PDIF and 1 network cable interface on the back of the fuselage, which also meets other types of usage needs.
- Picture: Brightness, color, and technology are excellent
Light source and brightness
First of all, let’s talk about the light source. The current mainstream light sources are LED light sources and laser light sources. LED light sources are relatively pure in color and small in size, but the brightness is low. Compared with traditional LED light sources, laser light sources have the advantages of beautiful colors, high brightness, and longer life. ALPD laser display technology is the leader among current laser light sources. It belongs to the theater laser light source. It not only has the traditional advantages of high brightness, high efficiency, long life, good color, and contrast of laser light sources, but also solves a major problem of laser light sources-speckle.
There were not many laser light source projector products before, and the most important reason was the speckle problem. Speckle refers to the light spots caused by coherent light reflected from a rough surface. In fact, it looks like there will be bright and dark spots on the screen, which makes the eyes uncomfortable. The use of ALPD technology allows an additional nano-luminescent rare earth material to be added to the optical system, which can effectively control the scattering of light and thus solve the speckle problem. The AOC EliteVision laser projector uses ALPD laser display technology, which optimizes the display effect from the light source, making the picture more vivid.
In terms of brightness, the AOC EliteVision laser projector has a high brightness of 2500CVIA lumens. CVIA lumens is the new unit of brightness in the current projector industry. According to the ANSI test method, the brightness is about 4500ANSI.
High-brightness projectors have an advantage in displaying many scenes. For example, the high brightness of the AOC EliteVision laser projector of 2500CVIA lumens can make the light of the picture more transparent, and the picture clarity is higher and more realistic. At the same time, it can also improve the color effect to a certain extent, making the picture bright and vivid, not affected by external light, and can be used during the day and at night, with more outstanding effects.
- Color performance
AOC EliteVision laser projector uses D65 color temperature (i.e. 6500K color temperature). D65 color temperature is one of the recognized standards in the current projector industry. Using it as a standard is both persuasive and a reflection of AOC’s professionalism. In fact, projectors with D65 color temperature have more natural colors, and the display effects and details are more delicate.
In addition, thanks to AOC’s 80 years of technical accumulation in the video field, AOC EliteVision laser projector is particularly outstanding after precise color adjustment: 10-bit color depth, 1.07 billion color display, smoother color transition without fault phenomenon; high color accuracy of ΔE＜1 means almost no color deviation, close to standard color. The high native contrast of 2000:1 has richer light and dark levels, more prominent dark details, and the courage to use native contrast really reflects AOC’s confidence in EliteVision laser projector, which is much more real than many manufacturers with nominal dynamic contrast.
- Screen technology and expansion
The high-speed interface of HDMI2.1 enables the projector to transmit at 240Hz. 240Hz transmission means that the projector can have stronger expandability. Many traditional projectors have average compatibility and cannot be connected to next-generation consoles in most cases. It is really cool to play games after connecting the AOC EliteVision laser projector to Xbox and PS5! The high refresh rate brought by 240Hz transmission makes the control of console games stronger, and it is easier for people to get an “immersive” experience when playing, so as to immerse themselves in it.
The addition of MEMC motion interpolation is a further sublimation of the projector’s screen effect from a technical perspective, making the AOC EliteVision laser projector more fluid in scenes such as fast-moving sports games and games, and the screen effect is more unified without any sense of fragmentation.
- Excellent chip
Excellent images are inseparable from excellent CPU and DMD chips. The CPU used by AOC EliteVision laser projector is MT9669, quad-core Cortex-A73 architecture, main frequency is 1.3GHz; GPU adopts Mali-G52 DDR3 architecture, and integrates an independent AI processor APU with a computing power of up to 1.0TOPS, which is the current mainstream flagship chip. Due to the improvement of overall computing power, the combination of 0.47DMD display chip can make the overall picture effect of the projector have advantages in brightness, picture color, dark field noise, which can be said to be all-round.
Sound: Sound quality restoration, unique low frequency
The speakers on the AOC EliteVision laser projector are jointly tuned with Devialet. Devialet is a French high-end audio brand and also the exclusive brand of the Paris Opera House. In the folk HiFi circle, Devialet is famous for its high-fidelity sound quality and shocking bass, and has won high recognition from many audiophiles.
I personally like Devialet, so I focused on the overall listening experience of the AOC EliteVision laser projector.
After a trial listening, I found that the sound quality of the AOC EliteVision laser projector is relatively restored. No matter what type of song it is, it can be heard. There are indeed many details in the sound. Some songs can even hear people’s deep emotions through potential details. From the perspective of the three frequencies, the low frequency is more distinctive, the sound is particularly powerful and wide, and compared with other projectors, there is a little more elasticity and full vibration of the sound, and the sound effect is unique; the effect of the mid-high frequency is also excellent enough, the mid-frequency sounds very thick, and the high frequency is slender and penetrating, but not sharp. In terms of overall listening, I like the AOC EliteVision laser projector very much.
Smart adjustment function: “Smart” and easy-to-use automatic adjustment
1. Omnidirectional non-sensing automatic correction: fully automatic trapezoidal correction, real-time correction, free placement. This function of AOC EliteVision laser projector is different from ordinary automatic correction. Sensing automatic correction mainly uses camera to achieve the effect of positioning the projector and the wall, while non-sensing generally uses laser focus sensor to achieve the effect of positioning the projector and the wall. It is faster and the non-sensing automatic correction has a better physical experience. It also makes the placement of the projector easier. Now, with AOC EliteVision laser projector, it can be said that a perfect trapezoidal screen is always displayed.
2. Ambient light adaptation: Many projectors keep the screen brightness unchanged regardless of the ambient brightness. However, in some cases, such as late at night, it does not need to be too bright. AOC smart projector EliteVision can automatically adjust the brightness according to the ambient light brightness, making the eyes more comfortable and not causing visual fatigue due to excessive or low brightness.
3. Laser non-sensing autofocus: Compared with the traditional camera focusing method using the focus map, the AOC EliteVision laser projector uses multi-point laser TOF non-sensing autofocus, which is faster and more efficient. During the focusing process, there will be no series of poor focusing effects. The focusing speed and focusing effect have been greatly improved.
In addition to the above three cores, the AOC EliteVision laser projector can also be optimized through AI algorithms combined with TOF+CMOS modules to automatically identify obstacles for intelligent obstacle avoidance. The automatic screen alignment function that automatically identifies the screen and automatically enters the screen with one click is also a very useful intelligent function. The above functions can effectively improve the experience in daily use. The projection area can also be adjusted between 30 and 300 inches, which can adapt to use in more scenarios.
Other technologies: details show more care
WiFi6 technology
AOC EliteVision laser projector is equipped with WiFi6 technology. Compared with the previous generation of WiFi5, WiFi6 technology has a much larger bandwidth, a more stable connection, and more frequency bands. In fact, I have not experienced interruptions, crashes, or sudden drastic speed drops when using it. The overall signal speed is also much faster than before, and there will be no frequent “circling” when watching high-definition movies with 4K picture quality.
Low noise and good heat dissipation
In fact, if the level of the projector is average, then it is likely to have a certain amount of excessive noise during daily use. Imagine watching a movie with a projector buzzing next to it. How can you achieve an immersive effect?
However, the AOC EliteVision laser projector has only 26 decibels during daily operation, and almost no obvious sound can be heard. Only when high-power heat dissipation is occasionally required, the slight rotation of the fan can be heard. This shows that AOC’s self-developed high-efficiency ice cooling system is indeed very powerful and has outstanding heat dissipation effect.
Summary
Finally, I think that when buying a projector, you must not only look at the brand or only look at a certain parameter, but you need to combine the picture, sound, system and other aspects to finally determine all the parameters of the projector and choose a truly comprehensive and balanced projector.
Of course, if you want to directly buy a suitable projector, then according to most customers’ selections, AOC EliteVision laser projector will be a very good choice, suitable for people in Generation Z who have a sufficient budget (more than $700) and pursue quality life; if the budget is not so sufficient, only 5K, the basic version of EliteVision LED projector AstroRay is also an excellent choice. Except that the light source is LED light source and the memory is slightly lower, the other configurations are basically the same as EliteVision. Recently, AstroRay and EliteVision new products will have a large discount on the market, so you can also pay attention to it!
