Optoma's HD290 home projector has a brightness of 3,000 lumens, a physical resolution of 1920*1080, and a contrast ratio of 20000:1, enabling a sharp, sharp high-definition viewing experience with a 1.3X optical lens with a throw ratio of 1.57 to 2.05: 1. The 100 inch 16:9 screen can be projected at distances of 3.48 meters to 4.54 meters, giving the user more freedom in the projection distance. At the same time, Optoma HD290 can also directly connect Blu-ray machines, TV boxes and game consoles and other common 3D devices to achieve 1080P 3D projection, to achieve more colorful viewing experience. The Optoma HD290 is equipped with TI's new generation of chips with the ability to double the frequency, allowing the display to be smoother and more stable, complete digital transmission without distortion, and complete 3D Blu-ray 1080P decoding.
Optoma HD290 uses a six-segment color wheel to achieve a brighter, brighter color. You can use the user's existing living room environment to enjoy the home theater fun, no need to worry about the ambient light source affecting the details of the experience, enjoy great movies, speed games and other large-screen entertainment Experience.

Quality experienceThen we entered the actual viewing of Optoma's HD290 home projectors. We used the currently used high-definition box to connect with the machine in the video performance, and tested it through the high-definition video content of the built-in Mango TV client. We chose the recent mango TV hit series “Special Service Elite†to test its image quality performance. We can see through the viewing effect that Optoma HD290 home projector is an entry-level 1080P model. Its image quality rendering ability is still quite good, regardless of the brightness of the screen, the sense of layering, the emotions of the characters in the play and other details can be captured, used as a general user to watch videos, can be competent. Of course, there are insufficient places, that is, the sense of smoothness of the screen is still not enough, some of the lack of jitter processing of the moving picture, the texture of the character skin is not particularly good.
In order to further reflect the picture quality of Optoma HD290, we also used it for a static screen display. It can be seen from the real shot effect chart that the overall picture is warm, the color of the gorgeous, the details of the restoration are basically in place, the screen looks It is very comfortable and the level of light and shade is also very clear.
In addition to watching videos and still images, we also conducted professional image performance tests on the Optoma HD290 home projectors, that is, testing its three primary colors, grayscale, and transparency. In the three primary colors test, Optoma HD290 home projector performance in general, full of colors but not enough gorgeous, while the overall color uniformity needs to be further improved, the three primary colors to restore the basic in place, the overall color display to meet the needs of entry-level users can still of. In the permeability test, the color transition fusion between Optoma HD290's neighbors is OK, and there is no strong rainbow effect. However, the same problem still remains. The overall color is not high, and the overall vision is not Silky natural feeling. In the grayscale test, Optoma HD290 home projector is also good, each gray block distinction is obvious, 256 gray scale only the left two columns are slightly blurred and indistinguishable, the rest can be clearly resolved, which is also a good reveal In the actual viewing time, when the light and dark scenes were switched, Optoma HD290 was a good reason.
As a whole, as an entry-level home projector with a price of only 3999 yuan, the Optoma HD290 has remarkable performance, 3000 lumens of brightness can be used in the general ambient light of the living room, 1080P mainstream resolution, 20000:1 Contrast, can give the user a clear, sharp image, 1.3X optical lens, 1.58 ~ 2.06:1 projection ratio, in a small space, you can also enjoy the uniqueness of the big picture.
The most important thing is that the price of Optoma's HD290 home projector is not high, which is affordable for the average user. Compared to the high-level range of 4K products, this product is very close to the people. Believe that the audio quality is not very demanding home projector entry-level users, buy such a product, not only to meet the picture quality experience brought by the big picture, but also appears to face the atmosphere trend.
