Chaoqing big screen to vote for you - Ethan D1 smart projection combat articles

In the first out of the box appearance of the Ethan D1 evaluation series, we saw the high value of D1 in the first article of the “Out of the box”. (Audio Entertainment Almighty Warrior - teach you to play Fundan D1 smart projection), we popularize the D1's UI interface, entertainment resources and some simple extension applications; in today's measured articles, we will focus on evaluating the most attention The hardware parameters, basic capabilities, audio and video decoding capabilities testing and projection applications and effects.

The CPU-Z measured hardware information is as follows.

D1 adopts Mstar 6A928 processor with Mali-760 MP4 GPU, 3GB DDR3 running memory, 16GB EMMC high speed flash memory, 1.2x optical zoom, high transmittance coated lens, projection ratio of 1.25-1.37:1, 16:10 aspect ratio , Three LCD display technology, resolution 1920X1200, brightness 1000 ANSI lumens, contrast 3001-5000:1.

The data measured by Nenamark2.4 is slightly lower.

For a variety of formats, audio decoding capability is strong, supporting a variety of mainstream formats including DTS audio decoding.

The TV professional chip solution Mstar 6A928 processor meets the 3G high-delivering video decoding capability. It supports the decoding of most video files in the market and supports video decoding in 3D, 4K, and H.265 formats, especially Most of the 4K video decoding capabilities on the market is commendable, playing smooth and clear. At present, D1 has insufficient support for HDR (high dynamic range) image frames. With the generalization of HDR technology in 4K video applications, D1 may subsequently solve this problem through firmware upgrades.

D1 adopts 3LCD display technology, and the picture quality will be significantly improved compared to common DLP display technology. The 3LCD method decomposes light emitted from a light bulb into light of R (red), G (green), and B (blue) (three primary colors of light) and transmits the light through the respective liquid crystal panels (HTPS method). Shapes and movements. Since these three primary colors are often projected, light can be used effectively and bright and clear images can be produced. The 3LCD projector has bright, natural and soft images. Since three LCDs are used to display colors, images that do not harm the eyes can be reproduced. The 3LCD method can also effectively solve the rainbow-like pattern known as "color decomposition", which can comfortably enjoy images for a long time.

Compared to the DLP display technology, the volume of the optical engine using the 3LCD technology is much larger, which is why the volume of the D1 is much larger than that of the smart micro-projection volume using the DLP technology. In order to sacrifice portability for more pure picture quality, the merits and demerits of this approach are seen as wisdom. For family audiophiles, such problems are not a problem at all. They will undoubtedly choose the latter in terms of volume and picture quality; For the average user, besides the special users who are considered for portability of travel on their own, most home projectors are relatively fixed in position, and even when they are decorated, the lifting positions are left. Concerns are ignored when it is actually used.

Brightness 1000ANSI lumens, can basically meet the needs of home viewing. In the dark environment, the picture quality and brightness of the D1 are excellent. The following are real shots of some 4K videos and pictures, using a 100-inch 16:10 fiberglass screen with a projection distance of about 2.5 meters. In addition to the picture below, it is convenient for uploading forums to do the picture size compression. For the picture, there is no post-modification processing.

With the use of a square pixel architecture, the Ethan dens D1 has a sharp reduction in image edge jaggies, which is particularly evident in text display. With WPS office system, you can easily play text, Excel, PowerPoint, PDF, TXT and other text image formats, users can get rid of the shackles of the computer , By directly connecting to the mobile storage for text presentations, meeting the needs of the conference lectures.

In addition to the video resources of Mango TV, D1 has also joined IQIYI's online video content, allowing users to choose from a richer selection of genuine online video resources.

In a bright environment with direct lighting, the color and picture quality performance will be weakened, details will be lost, but it can still meet the general viewing requirements. For home-level LED smart projection, the best viewing environment is still black, this is an indisputable fact, so to get a satisfactory viewing effect, users are advised to add a perfect blackout measure to the room where the projector is to be placed.

In addition to the curtain, the user can also choose a white wall to project according to local conditions. The effect is also good. The following is the author's projection effect in the dark environment of the pale pink diatom mud wall. If it is projected on the white wall, the effect will be better.

There is a lot of controversy about whether or not smart projection should have its own sound system. The solution that Miji had previously provided is to bring a Harman Kardon sound to the extreme, and to achieve the ultimate in sound with the smallest possible volume. It can also be selected via Bluetooth or Other interface external audio equipment. Although Kami Rice has done a very good job in this area, there are still enthusiasts who do not buy it. They think that their own sound effects are too poor, and that sound and pictures do not come from one direction, and people who are accustomed to watching movies and television Not adaptable.
