With the improvement of housing conditions, everyone's living room is getting bigger and bigger, and a high-specification projector in the living room is the choice of more and more families. And the projector currently has a variety of brands and models, how to choose it. In fact, at present, there are only two large classifications of projectors, which are divided into traditional bulb light sources according to light sources, and new LED light sources in the past two years.
▼ The traditional bulb light source has the advantages of high brightness and good color, and in the early days, there was little attention paid to the intelligent system, many best-selling models did not have built-in intelligent systems, and the main force was basically the traditional old projector manufacturers. The current lamp service life has actually been greatly improved, generally 2-3 years of life, replacement is also very cheap.
▼ The LED is the main long life, generally defined as 10 years, small size, but relatively low brightness, has always been combined with the built-in intelligent system, as well as a better built-in audio as a selling point. More are the emerging Internet brands doing.
And high resolution has become the mainstream of this year, 4K resolution models, in the past in the past more than 10,000 yuan, or even tens of thousands of yuan, this year, whether it is a traditional brand, or an emerging brand, there are many million yuan within the 4K model launched, today got 2 of which are particularly representative of the product, Youpai K701-4k as a traditional light bulb machine, joined the intelligent system, the highest brightness reached 3700, Jimi RS Pro2 emerging brand launched flagship model, the same 4K resolution. What are the advantages and disadvantages of each of them, let's find out.
1. Parameters
From the parameters of the difference between the two mainly in brightness, projection ratio, and the configuration of the built-in system, there is also a difference of one thousand yuan in pricing. Ultra-high-pressure mercury lamps used by UPAI provide better brightness, as well as a larger projective ratio that can project a larger area at the same distance. At the same time, Youpai K701-4K also overcomes the problem of short bulb life of traditional light bulb machines, and the life of the bulb reaches 20,000 hours, which can be used for 13 years in 4 hours per day. Jimi has more memory and storage space in the built-in system, as well as a 20w higher power speaker. Specifically, we still have to look at the experience, we look at the actual experience.
Second, the appearance
Let's take a look at the contrast between the two appearances, the body shape is flat and a square, but the volume of the host pole meter is a little smaller. In terms of color, one black and one white have their own characteristics.
However, if you count the external power supply, there is no difference between the two in terms of volume, and Jimi adopts the design of external power supply, while Youpai is a built-in power supply.
The front of The View is a projection module, using a 4K optical lens composed of high-quality image glass, and the lower half of the lens is also obscured to avoid dust during hoisting, and can also protect the lens in daily use.
Jimi's lens adopts a hidden design, and the upper baffle will be lowered after booting, which has a good overall feeling and can also play a role in shielding dust.
The back interface part is basically the same, there are 2 HDMI interfaces, and 2 USB-A interfaces, as well as 3.5-inch headphone interfaces, Youpai also has AVGA interface, compatible with the needs of the office. Jimi also has a network cable and fiber optic interface.
In terms of heat dissipation, Youpai adopts the left air intake, right exhaust design, and the pole meter is the bottom air intake, rear exhaust, hoisting two there is no difference, if placed on the coffee table to use, the rear exhaust has the possibility of blowing legs, and the side exhaust does not have this problem. There is no difference in noise between the two, and the light bulb machine is equally quiet.
Both models at the top have physical buttons set.
Youpai also has a zoom and focus knob in the front, using a manual focus and zoom design, the projector generally does not move for a long time after placement, so manual adjustment is not troublesome.
In terms of buttons, Youpai is configured with full-featured buttons, which can complete the adjustment of various parameters and achieve the same functions as on the remote control.
The jimi buttons are mainly set for playing music, which can complete the adjustment of the volume and the rotation of the song.
The two settings of the remote control part are very similar in terms of volume and ergonomics, and the grip is very comfortable. Both are equipped with a speech recognition button, which can be pressed to send commands to the projector by voice.
The Remote Control button of Youpai also has a light source in it, which is particularly intimate in the projection environment suitable for use in dark light.
Third, the actual measurement
All comparison charts above [Youpai], below [Jimi]
3.1 Brightness
In the evening test of completely closing the curtains and turning off the ceiling lights, using the same ordinary white curtain, the brightness of both can meet the needs of the movie, which is also the best environment for the projector. There is still a certain difference between the two in color tuning, the warm side of the Excellent Pie, and the cool side of the extreme rice. There is no good or bad between the two.
In the environment of opening the curtains during the day, the difference between the two is relatively large, and the higher brightness of the Youpai can still see the picture, and the extreme rice in this environment, the whitening is more severe.
3.2 Projection ratio
At the same distance, the maximum size that the two can project also has a certain difference, youpai can project a larger picture, in my home this coffee table and the curtain more than 2 meters away, youpai can throw 84 inches of curtain, and jimi is not satisfied. For a limited area of the home, the smaller projection ratio is still better.
In addition to frontal projection, both machines also support the test and projection function, and Youpai can be manually adjusted between the left and right gradients ± 40°, the upper and lower gradients ± 40°, and the adjustable range is larger. It is also worth mentioning that K701-4K can realize the function of surface adjustment, and the projector can complete the creative interpretation of curved, spherical, cylindrical and other special-shaped screens, and calmly face a variety of different projection environments
3.3 Resolution
Using the resolution test chart, you can see that both resolutions can reach the standard of 4K, the projector has not been able to popularize 4K for so many years, 4K is not useless, but the price of 4K projection has been too expensive before, for most of the projection size is 100 inches to start the demand, 4K compared to 1080P image quality The improvement of fineness is visible to the naked eye. The Premium K701-4k maintains the cost-effective basis of the previous generation and also adds the intelligent system as well as WiF and Bluetooth, which further improves the cost performance.
From the details of the text, the Yopai K701-4k is also relatively more delicate, the text edge is sharper, and the effect is better when the projector projects PPT.
3.4 Contrast
In the contrast test, the contrast ratio of Youpai 25000:1, relatively speaking, the color transition is more natural, in the color map, the more obvious the mountain shape, the better the color transition, and the comparison of the two pictures, the mountain shape of the Youpai is more obvious.
In the transition of the sphere, from dark to bright, the level of youpai is also more. The sphere is also more rounded.
In terms of actual image display, in this picture with both highlights and shadows, the level of detail of Youpai will be more, the details of the shadows will be retained, and the highlights will not be overexposed, while the highlights of the extreme meter will be slightly overexposed.
In terms of color configuration tools and color optimization technology, Youpai has its own unique advantages, set up vColorTuner color grading technology, innovative color configuration tool software, users can run the tool program on the PC side, PC through USB and projector connection, color configuration, you can also call the technology god on the network to share the preset file, so that the color configuration is more convenient and diverse. And ViewSonic SuperColor technology, which provides a wider color gamut to ensure color performance and color saturation.
3.6 Game Performance
For csgo this kind of shooting game, it can be said that every second must be competed for, both of which support a high refresh rate of 240Hz, for games with 200 frames at every turn, it is really a perfect match, the screen is smooth at the same time, but also less vertigo. The high refresh rate is obviously improved in actual combat, when the opposite side jumps out or flashes out to hit you, you can see more details of his actions, not to have the feeling of "teleportation", and the picture will not have a sense of dragging and stagnation, at this time you are more likely to counterattack the opposite side.
Both models have good game performance under high refresh and low latency. The immersion of playing games on a large screen is unmatched on a small screen monitor.
K701-4K has HDR projection technology, support HDR10/HLG content display, through the picture quality processing engine can truly restore the rich bright color information in the HDR signal, automatically adjust the brightness of each area, perfectly present brighter white and deeper black, bring better contrast and restore natural reality; Compatible with REC.2020, it can project REC.2020 signal format normally. As can be seen from the above GIF, the details of the dark part of the game can also be displayed.
3.7 Built-in system
This time, the built-in system of Youpai K701-4K adopts tencent Aurora tv system, which has a rich film source, 4K resolution TV movies, and also has 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, computers, etc., and the support of 2.4g/5g dual-band wifi provides a guarantee for the stability of the screen projection. In terms of wireless connection, it still supports Bluetooth, and you can connect Bluetooth speakers and headphones. The system supports the installation of third-party apps, and various types of playback software can be installed to remotely play the content in our nas. The playback of 2+16g configuration 4k local film source is also not stuttering.
Jimi uses the system of Mango TV, which can also install various third-party apps, access Tencent, iQiyi, etc., and the overall system is not much different from Thatpipe's.
Of course, Jimi also has its own advantages, it has a set of built-in high-bit rate true 4k large-capacity film source download system, built-in more than 200 single-piece volume of about 20g of high-quality film source, these we usually have to use nas to download, their own to find the film source is more troublesome, but this set of film library is also to be charged separately, the annual fee of 500 yuan per year, the cost is still relatively high. This is also the reason why he configured 128g of storage space.
4. Summary
Well, it's time to summarize, Youpai K701-4k has better performance in brightness and projection ratio, as well as color performance, built-in intelligent system, but also to make up for the shortcomings of the previous generation, and Jimi has certain advantages in the hardware configuration of the system, high-quality film source and audio configuration, but the price is about a thousand yuan, overall is a very good product, how to choose or depends on everyone's focus.
