The traditional bulb light source has the advantages of high brightness and good color. In the early days, it didn't pay much attention to intelligent systems. Many best-selling models do not have built-in intelligent systems, and the main force is basically traditional old projector manufacturers. At present, the service life of light bulbs has been greatly improved, generally 2-3 years, and replacement is also very cheap.
On the other hand, LED focuses on long life, generally defined as 10 years, which is small in size but relatively low in brightness. It has always been a combination of built-in intelligent system and better built-in audio as a selling point. More are emerging Internet brands.
And high resolution has become the mainstream this year. In the past, the models with 4K resolution were more than 10,000 yuan, or even tens of thousands. This year, both traditional brands and emerging brands have launched many 4K models within 10,000 yuan. Today, they got two particularly representative products. As a traditional light bulb machine, Youpai K70 1-4k has added an intelligent system, with the highest brightness reaching 3700 and the polar meter RS Pro2. What are their advantages and disadvantages? Let's find out.
From the parameter point of view, the difference between the two is mainly in brightness, projection ratio, and the configuration of the built-in system, and there is also a difference of 1000 yuan in pricing. Ultra-high-pressure mercury lamp used by Youpai can provide better brightness and larger projection ratio, and can project a larger area at the same distance. At the same time, Youpai K70 1-4K also overcomes the problem of short bulb life of the traditional bulb machine. The bulb life reaches 20,000 hours, and it can be used for 13 years according to the calculation of 4 hours per day. On the other hand, Jimi has more memory and storage space on the built-in system, and also has 20w high-power audio. The details still depend on the experience. Look at the actual experience.
Let's take a look at the appearance contrast between the two. In terms of the shape of the fuselage, one is flat and the other is square, but the size of the main engine is a little small. In terms of color, one black and one white have their own characteristics.
But if you count the external power supply, there is no difference in volume between the two. Extreme rice adopts the design of external power supply, while Youpai is the internal power supply.
The front of Uniview is a projection module, which is made of high-quality image glass. The lower part of the lens is covered to avoid dust during hoisting, and it can also protect the lens in daily use.
The ultra-meter lens adopts hidden design, and the upper baffle will be lowered after starting, which has a good overall feeling and can also play a role in shielding dust.
The back interface is basically the same, with two HDMI interfaces, two USB-A interfaces and a 3.5-inch headphone interface. Youpai also has VGA interface, which is compatible with office needs. The polar coordinate meter has another network cable and optical fiber interface.
In terms of heat dissipation, Youpai has adopted the design of "left in and right out", while the polar rice has no difference between bottom air intake, rear exhaust and hoisting. If it is used on the coffee table, the exhaust air at the back may blow to the legs, but the exhaust air at the side does not have this problem. There is no difference in noise between the two, and the light bulb machine is also very quiet.
At the top, both models have physical buttons.
Youpai also has a zoom and focus knob at the front end, which adopts manual focus and zoom design. Generally, the projector will not move for a long time after being placed, so manual adjustment is not troublesome.
In terms of buttons, Youpai is equipped with full-function buttons, which can complete the adjustment of various parameters and realize the same functions as those on the remote control.
The keys of the instrument are mainly set to play music, which can adjust the volume and rotate songs.
The two remote controls are very similar in size and ergonomics, and the grip is very comfortable. There is a button with voice recognition, which can send commands to the projector by voice after being pressed.
Youpai's remote control button also has a light source, which is particularly intimate in a projection environment suitable for dark light.
All the comparison charts are excellent, and the next shot is rice.
3. 1 brightness
At night, the curtains are completely closed and the ceiling lamp is turned off. Using the same ordinary white curtains, the brightness of both can meet the needs of watching movies, which is also the best use environment for projectors. There are still some differences in color adjustment between them. yomi is warmer, and the extreme meters are colder. There is no difference between the two.
In the environment of opening curtains during the day, there is a big difference between the two. You can still see the picture clearly with higher brightness, but in this environment, the rice is whiter.
3.2 Projection ratio
At the same distance, there are some differences in the maximum size that they can project. Youpai can project a bigger picture. In my family, when the distance from the coffee table to the curtain is more than 2 meters, Youpai can cast 84-inch curtains, but the meters are not enough. For a limited family area, the smaller the projection ratio, the better.
In addition to front projection, the two machines also support measurement and projection functions. Youpai can manually adjust between the left and right gradient of 40 degrees and the upper and lower gradient of 40 degrees, with a wide adjustment range. In addition, it is worth mentioning that K70 1-4K can realize the function of surface adjustment, and the projector can perform the creative deduction of special-shaped screens such as surfaces, spheres and cylinders, and calmly face various projection environments.
3.3 resolution
Using the resolution test chart, we can see that the resolution of both projectors can reach the standard of 4K. It is not that 4K is useless because projectors have not been popularized for so many years, but that the price of 4K projection has always been too expensive. For most requirements that the projection size starts from 100 inch, the image quality improvement of 4K relative to 1080P is visible to the naked eye. On the other hand, Youpai K70 1-4k maintains the high cost performance of the previous generation, and also adds intelligent systems, wif and Bluetooth to further improve the cost performance.
From the text details, Youpai K70 1-4k is also relatively more delicate, and the edges of the text are sharper. The effect is better when projecting PPT with projector.
3.4 Comparison
In the contrast test, the contrast of Youpai 25000: 1 is relatively more natural. Chromatographically, the more obvious the mountain shape, the better the color transition, while comparing the two pictures, the mountain shape of Youpai is more obvious.
In the transition of spherical surface, from dark to bright, there are more levels of excellent calibration. The spherical surface is also smoother.
In terms of actual image display, in this picture with both highlights and dark parts, there will be more details of the excellent shot, the details of the dark parts will be preserved, the bright parts will not be overexposed, and the bright parts of the meter will be slightly overexposed.
Youpai has its own unique advantages in color configuration tools and color optimization technology. It is equipped with vColorTuner color matching technology and innovative color configuration tool software. The user can run the tool program on the PC, and the PC is connected with the projector through USB to configure the color. You can also call the preset files shared by the technical gods on the network to make the color configuration more convenient and diversified. The excellent SuperColor technology can provide a wider color gamut and ensure color performance and color saturation.
3.6 Game performance
For csgo, a shooting game, it can be said that every minute counts. Both support a high refresh rate of 240Hz. For a 200-frame game, it is really a perfect match, with smooth pictures and less dizziness. The high refresh rate is obviously improved in actual combat. When the opposite person jumps out or flashes out to hit you, you can see more details of his movements, so that you won't feel "teleport" and the picture will not be dragged and stagnant. At this time, you will be more likely to bump into the opposite person.
Both models have good game performance under high refresh and low latency. The immersion of playing games on a big screen is incomparable to that of a small screen monitor.
K70 1-4K has HDR projection technology and supports HDR 10/HLG content display. Through the image quality processing engine, the rich bright color information in HDR signals can be truly restored, and the brightness of each area can be automatically adjusted to perfectly present brighter white and deeper black, bringing better contrast and restoring nature and truth; Compatible with REC.2020, and can project REC.2020 signal format normally. As can be seen from the above animation, the dark details of the game can also be displayed.
The Uniview K70 1-4k built-in system adopts Tencent Aurora TV system, with rich film sources, 4k resolution TV movies and various children's animation resources, so there is no need to buy a TV box separately.
The system also supports wireless screen projection of mobile phones and computers, and the support of 2.4g/5g dual-band wifi ensures the stability of screen projection. Bluetooth is still supported in wireless connection, and Bluetooth audio and headphones can be connected. The system supports the installation of third-party apps, and can install all kinds of playback software to remotely play the content in our nas. The configuration of 2+ 16g is not stuck in the playback of 4k local film sources.
Extreme rice adopts mango tv system, and can also install various third-party apps to access Tencent and iQiyi. There is little difference between the overall system and the excellent school.
Of course, Jimmy also has his own advantages. It has a set of built-in download system with high bit rate and true 4k large-capacity film source, and more than 200 high-quality film sources with a single volume of about 20g are built in. We usually download these films with nas, so it's more troublesome to find their own source. But this movie library is also charged separately. The annual fee is still relatively high in 500 yuan. That's why he allocated 128g storage space.
All right, it's time to wrap it up. Youpai K70 1-4k has better performance in brightness, projection ratio and color performance, and its built-in intelligent system also makes up for the shortcomings of the previous generation. However, Jimi has certain advantages in system hardware configuration, high-quality film source and audio configuration, but the price is around 1,000 yuan, and it is an excellent product as a whole. How to choose is up to everyone.
