With the rise of DLP intelligent projection, there are many choices at the entry price. However, the industry is specialized, and enthusiasts still only recognize Epson, Sony JVC、 BenQ and other traditional projection manufacturers.
Epson has also started different attempts in recent years, producing the smallest 3LCD laser projector EF-10 in the market, and equipped with the intelligent system of Tencent Aurora. Although small and intelligent, EF-10 is still a laser projector focusing on image quality.
The reason why Amway is so simple and boring: The portable ones have better picture quality than the portable ones, and they are several circles larger than the portable ones. Of course, it's not because it costs 3999 yuan from time to time. Don't misunderstand it (the forehead is cold and sweating, and looks flustered).

Appearance and accessories
Epson EF-10 has many accessories. The body can be mounted on a VESA standard base or tripod after mounting a wall mounted/upside down bracket. All power adapters have brackets, which are Japanese factory flavor.
Heavy accessories, low-key and restrained workmanship, and inexplicable style can be perceived without looking at the quotation.
The size of the power adapter is close to the common 20000mAh mobile power supply, manufactured by Boyi, with a maximum output of 120W. The remote control is small and round, with all body frosting and soft silicone keys.
Epson EF-10 is solid and exquisite, which is the aesthetic feeling of industry. The main body is crocodile like skin texture, and the front is the surface treatment of "bright surface+dot".
It is all scratch free surface design, and its appearance will not be affected by rough growth and rough maintenance. This is not "easy to take care of", but no need to take care of it at all, I like it！
The tripod support and two nut type "rear feet" can also adjust the height and serve as the fixing holes of the support. The "front foot" under the lens is a traditional button locking type, with an adjustable height of about 3cm. The structure is nostalgic and can not be surpassed up to now, which is much easier to use than most of the telescopic feet of intelligent projection.
Perhaps considering that the projection ratio of the machine is 1:1, it can be used on the tea table. Epson EF-10 puts the speakers on the back and back of the bottom, and all the connectors are on the left. On the upper left side are earphones, nostalgic mini USB, USB-A and HDMI interfaces, and the anti-theft keyhole and power port are on the lower right corner.

Although there is a 0.62-inch 3LCD (larger than some 5000 yuan products, Surprise!) And 1000 lumens of laser light source, but Epson EF-10 is a moving projection of the body, is a textbook style small cannon.
Epson EF-10 3D is only 175 x 65 x 175 mm. What is this concept? Epson EF-10+adapter+remote control are not covered with a piece of A4 paper That's just too much. 1.2kg weight and 65mm thickness, complete It can be stuffed into your backpack to accompany you.
Simple LCD technology, popular science: distinctive advantages and disadvantages
Smart projection is accompanied by DLP technology, but now the public does not know much about 3LCD technology. Epson, the main manufacturer of the 3LCD camp, has almost become the synonym of 3LCD after it released the first 3LCD projector VJP-2000 in 1989.
3LCD and entry-level mainstream monolithic DLP are Two different technical routes have their own advantages and disadvantages , living in different price segments.
The core of DLP is to use the micro lens corresponding to the number of pixels to control the light, while the 3LCD uses three LCDs (the never slave LCD) to control the light split into RGB primary colors.
At the early stage of the two technical routes, the advantages of 3LCD are High light utilization, high sharpness, high color saturation, natural color scale change and good color accuracy , low power consumption, low heat generation, mainly due to the mechanical part, its mechanism is large, and the ventilation structure has the risk of ash feeding.
The advantages of monolithic DLP are High contrast, compact pixel arrangement, small size and low cost The disadvantages are poor color accuracy, loud noise, rainbow effect that may cause discomfort, stroboscopic and PWM dimming（ There is also a war between LCD and PWM in the projector, which is unexpected ）。
After years of evolution, the improvement of DLP has focused on the "cost" field, and even achieved low-cost 4K with dithering (Deyi can be called a time-domain money saver), while high-end products have improved the color gamut and used the speed doubling color wheel to reduce the color red effect. But the principle is limited, The picture effect of DLP still cannot win the 3LCD at the same price The rainbow effect and other problems affecting the appearance are still relatively obvious.
The improvement of 3LCD is mainly focused on the image quality field, successfully improving the opening rate, reducing pixel spacing, reducing the sand window effect and significantly improving the contrast. Like the Epson EF-10 we experienced this time, the contrast is as high as 2.5 million: 1, and the volume is unexpectedly small. Its saucy specifications and characteristics, coupled with the price of 4000 yuan, have a taste of dark magic.
Effect: another world
Epson EF-10 is equipped with automatic trapezoidal correction and manual focusing, but its nearest focusing distance can reach about 27cm. As long as you want, it can even be used as a 14 inch notebook, with huge brightness and no fear of sunshine.
The projection ratio of the projector is generally 1.2:1 to 1.4:1, and the laser TV (the laser projector placed on the TV cabinet) is generally about 0.2:1 to 0.3:1. The projection ratio of Epson EF-10 reaches 1.0:1 (the ratio of projection distance to image size), which is One of the projectors with the smallest projection ratio recently, which is extremely friendly to small family users 。
Epson EF-10 only needs 2.24 meters to throw 150 inch pictures, and it can also throw a giant screen in a small room. For Epson EF-10, it is not the length of the living room that limits the size of the projection picture, but the size and height of the wall, which further tests the "cash ability".

At the moment when the projection is lit, the most obvious difference between 3LCD and DLP is not color, but image sharpness. Epson EF-10 is extremely sharp, "the world has never been so clear". Not to mention DLP projection, I have never seen such a picture with fine pixels in DLP laser TV before.
Its clarity is so high that when you look closely, you can even vaguely see red, green and blue sub pixels like a monitor, Amazing！ In addition to sharpness, the image of Epson EF-10 is also clearer and less noisy than the common DLP projection. This part is difficult to express in words. If you have the opportunity to see these new 3LCD projectors offline, you can understand that seeing is better than hearing.
On the one hand, the light utilization rate of the 3LCD should be higher, and on the other hand, it may be related to the quality of the lens. However, there is no way to investigate the specific reasons. After all, Epson is different from many manufacturers. Some manufacturers will deliberately publicize their use of glass lens sets when they announce it. However, Epson EF-10 with glass lens is not mentioned at all on the official page. Maybe Epson thinks this is the basic requirement for projectors
In terms of brightness, the official standard of Epson EF-10 is 1000 lumens. 1000 ASNI lumens is approximately equal to 800 ISO lumens conversion, which is approximately equal to 1250 ASNI lumens. In the system, the light source brightness only supports the adjustment between 50% and 100%. The parameters sounded ordinary, but the fact hit my face mercilessly - there was a brightness called "1000 lumens of Epson 3LCD".
Accustomed to the 50% - 100% falsely labeled brightness labels in the DLP market (the specific range depends on the conscience of the manufacturer), we have a cognitive bias in the actual perception of the unit lumen.
Dark scene with only 1/4 light on in the living room ↑
In actual use, the brightness of Epson EF-10 is higher than many DLP projections with 2000 ASNI. When the light is turned on without a screen (the brightness of common office environments is 100 to 150 nits), Epson EF-10 can meet the basic viewing needs. If you want to use it in the living room during the day, you need to match the screen and control the picture at about 100 inches. When the projection size is below 150 inches, 80% of the brightness can be used in the darkroom environment, and then the brightness is really dazzling.
Projected to the white wall, the image is compressed to about 35 inches for testing, and its equivalent brightness is up to 4644 nit. In terms of color performance, 3LCD does have obvious advantages over DLP, and its color is really richer than DLP projection at the same price. When the color is not calibrated, the actual color gamut covers 95.8% of sRGB, the red part is obviously larger than sRGB, and the green and blue parts do not hit the standard color block, but still It is much better than the DLP with color bias to the Milky Way at the same price 。
The color temperature of the built-in theater mode is 7553K, the color temperature of the bright theater is 7855K, and the color temperature of the natural mode is 6779K. Except for the natural mode, the other modes are set to be slightly cold.
The following is Epson EF-10 in 100% brightness, 150 inch projection, live picture in cinema mode:

In the discrimination test chart, complex textures such as fonts are at full HD level. In the horizontal and vertical lines, we can recognize a level close to 4K, which is so exaggerated that I doubt whether Mr. Qian designed this picture according to DLP projection.

In terms of heating, the room temperature is 26.5 degrees, the highest brightness works for 1 hour, and the highest temperature appears at the lower right of the logo on the back, 49.8 degrees; The air inlet on the left side of the lens is the area with the lowest temperature of the whole machine, 35.9 degrees; The right air outlet is 48.4 degrees, and the heating control is good.
System and possibility of not playing cards according to routine
Application page
The system part of Epson EF-10 is Tencent Aurora, the bottom layer of Android 9.0. The power on is a little slow, but the power off is second after second, and OTA is very dense. After all, it is the work of an old brand manufacturer. Naturally, there is no advertisement on the machine.
But the most annoying thing is that I brought my own sofa butler (which is equivalent to giving you the whole world to understand), and did not play cards according to the routine. In addition, music broadcast, QQ music, ink weather, Wukong literacy, opera in Liyuan Keep、 Instant sports are all equipped with their own APP.
Application management page
In the performance part, AIDA 64 shows amlogic SoC, 4-core 1.8G A53 CPU+Mali-G31 MP1, 2G memory+8G storage. The smoothness of the system is OK, and the optimization of the goose factory is OK. The most impressive part of the system is actually remote control.
Epson EF-10 remote control has many shortcut keys, which is a typical "anti intelligent thinking". One button closing sound and picture, picture setting OSD, trapezoidal correction, user mode, and input source all have their own physical buttons, which are more practical than remote control for simplicity.
Now the so-called minimalist remote control is minimalist, but the operation becomes cumbersome. Every time the screen parameter adjustment, input source control and other high-frequency operations have to repeatedly enter the menu, so I want to greet the designer # ￥% @ ￥ #...... ￥ #% # @
Epson's traditional setting interface exists in the form of OSD, and calls out directly from remote control. In fact, this part is an independent complete projection system, in which HDMI connection mode, sleep mode time, power on connection mode, etc. can be customized. It can not only record multiple sets of settings like a computer BIOS, but also use a USB flash drive to migrate system settings between devices.
Brightness, contrast, and gamma settings
Gamma Detailed Settings
Saturation, hue, white balance, RGBCMY adjustment
Users who have never been exposed to traditional TV/projection may be shocked to see this part. But for users and enthusiasts who come from the traditional projection, this is what a professional device should look like.
There are many adjustable items in the picture part, which is more professional than many 10000 yuan smart laser TVs. This is the accumulation that old manufacturers can't hide. Color space (YCbCr444, YCbCr422, RGB), video range (16-235 and 0-255 output), white balance, definition, noise reduction, MPEG noise reduction, and detail enhancement can be adjusted.
In particular, the adjustable items of RGB shift and increase (50 levels each) for RGB (red, green, blue, yellow, cyan, magenta), three primary colors, and five level gamma (as well as user-defined 9-point mode) make it possible for software like HCFR to adjust colors. After all, the color space determines a projected ceiling and its possibilities.
Summary: Textbook style small steel cannon
DLP products are popular in the mainstream market, and most users have only used DLP projection and DLP laser TV. However, if you can see Epson's new batch of 3LCD laser projectors, you may have a new understanding of the practicality of projectors.
Epson EF-10 inherits the characteristics of high color sharpness, high color saturation and natural color scale change of the 3LCD projection, has rich picture adjustment items, and has a true brightness of 1000 lumens. At the same time, it also makes the 3LCD projection a portable device that can be stuffed into a backpack. The 1.0:1 projection ratio does not select the environment. Indoor and outdoor are suitable. Whether it is mobile office, family and friends gathering, or going out for play, as long as there is a white wall, it can give you a different night.
There are also disadvantages. For example, there is no default jump HDMI setting, the USB port is a bit picky about storage devices and video formats, and the audio system is not top of the line. However, this does not affect the Epson EF-10 becoming one of the top machines in the price range of 4000 yuan. If there is not too high demand for audio, more emphasis is placed on image quality, and there is a certain demand for portability. Don't ask, ask Epson EF-10.
