20,000 to buy 4K Optoma ultra HD flagship projector evaluation

There is a cover at the top of the Optoma UHD620 home projector. After the cover is opened, two knobs can be used to quickly adjust the picture size and displacement. The focus ring is at the periphery of the lens. The user can adjust the focus by rotating it. . It is very convenient for users to use daily. In addition there is a physical button interface on the side of the fuselage, switch and some simple controls can be completed here, but the button interface is relatively small, the user may not be easy to find the initial use.

Optoma UHD620 home projector remote control with a backlight, looks beautiful in the dark state, while allowing users to use in a darker environment, this design can be said to be very humane. In addition, four rotary adjustment brackets are installed on the bottom of the machine, which can reach a length of about 3cm, making it easy for users who are shooting to adjust the projection angle.

Projector Data Testing We mainly use the ANSI standard developed by the American National Standards Association. This standard is also recognized as an authoritative standard in the industry. And consider the following aspects: maximum brightness, peak brightness, optimized brightness, and projector contrast color. Next, I will briefly explain a few technical terms for everyone: The first is the peak brightness, especially in the brightest mode, the highest brightness can be achieved at a single point, generally appear in the center point; maximum brightness, refers to the brightest mode The average brightness that can be achieved on the screen is higher than the reference value of this value; the optimized brightness, also known as ANSI brightness, is the average brightness of the 9 test points in the case that the projector just can distinguish eight gray scales.

With regard to the brightness of the projector, there are three data in the table, namely the maximum brightness, the peak brightness, and the ANSI brightness. In simple terms, the maximum brightness is the average brightness of the screen in the brightest mode of the projector (brightness, contrast, and lamp mode are all adjusted to the maximum). From the results of our actual testing, the maximum brightness of the Optoma UHD620 home projection is 2067 lumens, which is a nominal 64.6%. In general, this value is 90%, which is very good. The OHD620 home projector's performance in this respect can be said to be quite satisfactory.

Peak brightness refers to the maximum value that can be reached at a certain point on the screen in the brightest mode. In general, peak brightness is best if it can approach 95% of the nominal value or even exceeds the nominal value. From the actual test data, Optoma UHD620 home projection peak brightness of 2806 lumens, up to a nominal 87.7%, and the best standard is not much difference.

ANSI brightness refers to the ANSI test standard. As such, the ANSI brightness reference is more significant. From the actual test data, according to the ANSI test standard, the ANSI brightness of the Optoma UHD620 home projector has reached 1175 ANSI lumens. It can be said that this brightness performance can meet the market viewing needs of home users.

Color testing has always played a very important role in projector testing, and is also a concern for most users. In this link, we mainly understand the color reproduction of the machine through the differences between color test proofs and real shot figures. ability. I think we must be very optimistic about the color performance of the OHD620 home projection projector. Do not worry, please continue to look down with me.

Through the above group of real shot map we can see that Optoma UHD620 household projector focus is clear, the color is structured. Compared with the style of the original image, the UHD620 home projection projection screen has a rich color. This color style is very appealing to the audience.

In the comparison of the four-color maps, we can see that the overall color reproduction degree of the Optoma UHD620 home projection is generally blue, the blue part is slightly purple, and the green part is a bit yellowish.

Optoma's UHD620 home projector looks elegant and elegant. The knobs behind the camera body and the focus ring on the outside of the lens allow users to quickly adjust the projection screen. It is very convenient. The interface behind the fuselage is rich, the spacing between holes is reasonable, and there is no pressure to connect multiple devices at the same time. In addition, the design of the remote controller is easy and the backlight is not only beautiful, but also convenient for users to use in the dark state.

Optoma UHD620 home projector measured brightness performance measured, the projection effect can meet the needs of home users. Another thing I have to say is the super clear picture of the machine. In the evaluation, we obviously felt the difference of the 4K picture. If users use the 4K HD picture at home to watch a large movie, it would be a different kind of experience than before.

Optoma UHD620 home projection color reproduction is high, wide color gamut, basically no color drift and other issues. The user's color experience during the viewing will be very good. Taken together, Optoma's UHD620 home projector performs well in all aspects. The 4K picture is very clear. If you are a user with high quality requirements, then this product is suitable for you.

Unconsciously, we have entered the era of 4K Full HD. Various 4K products have brought us high-definition screens that we could not even think of in the past. Naturally, the projectors are also indispensable. The Optoma UHD620 home projector that we want to evaluate today is a 4K product. How about the actual performance of this HD projector? Let's take a look with me.

Optoma's UHD620 Home Projector features HDR high dynamic range technology that delivers more vivid graphics and allows users to see more detail. Have to say, 4K HD picture with HDR high dynamic range technology, your viewing experience will be very different. In addition, the nominal brightness of the Optoma UHD620 home projection also reached 3200 lumens, which can also be watched safely during the day.

The projection ratio of Optoma's UHD620 home projection is 1.39-2.22. No matter what your home size, you can find a suitable installation location in the living room. The machine uses replaceable high-efficiency light bulbs, and its service life reaches 10,000 hours in the energy-saving mode. The cost for the home users is still relatively low.

These are the objective test results of Optoma's UHD620 home projection. Friends with limited time can understand this product through it. However, if you want to evaluate whether the projection is good or bad based on just a few objective values, it is not enough. Therefore, I still recommend that you make a judgment after looking at the entire evaluation.
