The standard resolution of the Sony VPL-U300WZ projector is 1280x800, combined with Sony's original signal processing error correction technology, the projection of the picture is clear and sharp. This product's LCD panel size increased from the conventional 0.59 inch to 0.76 inch, and the light resistance of the material has also been improved, which makes the machine's durability greatly enhanced. In addition Sony VPL-U300WZ projector equipped with a blue laser light source, theoretically can provide up to 20,000 hours of service life (actual time depending on the use of the environment and how to use the projector varies), can fully meet the education industry's high use intensity . Sony VPL-U300WZ projector has a light source brightness adjustment function, the machine brightness will automatically dim about 15% when the input signal does not change for 10 seconds. If no operation is performed after a predetermined period of time, the machine automatically detects the input signal and dims it to about 5% of the initial brightness, which can significantly reduce energy consumption and make it more energy-efficient and environmentally friendly. The above figure is the objective test result of the Sony VPL-U300WZ projector, you can use it to make a preliminary understanding of this product. However, if you want to thoroughly understand the advantages and disadvantages of a projection, it is certainly not enough to rely on only a few objective data, so I still recommend that you look at the entire evaluation. Well, here we enter the complete evaluation of the Sony VPL-U300WZ projector. Sony VPL-U300WZ projector's white body looks clean and elegant, the whole model is sleek and simple, it can be well integrated with the classroom environment. Behind the fuselage design HDMI, USB and LAN and other interface modes, users can simultaneously connect multiple devices. The Sony VPL-U300WZ projector has a double-layer electrostatic filter specially designed for the Chinese market, which effectively prevents dust and tiny fibers from entering the interior of the projector. In addition, the machine is also equipped with an efficient cooling system, while the exhaust outlet area of ​​the fuselage is also very large, which can ensure that the excess heat can be quickly distributed to the long-term use will not appear overheating of the machine. In the Sony VPL-U300WZ projector side of the fuselage has a physical button interface, the user can quickly operate the machine without the help of the remote control, daily use more convenient. In addition, an adjustment knob is installed next to the lens. After the camera is turned on, the user can quickly adjust the appropriate screen to effectively improve the classroom efficiency. 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 examine the following aspects: maximum brightness, peak brightness, and projector 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 of the picture can be achieved, this value is more valuable for reference. Eight gray levels and 13 illumination test points data analysis: Regarding the brightness of the projector, there are two data in the table, namely the maximum brightness and the peak 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 Sony VPL-U300WZ projector is 3955 lumens, a nominal 113%. The general maximum brightness is excellent even if it can reach the nominal 90%. The Sony VPL-U300WZ projector performs well at this link. 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. The actual test result shows that the peak brightness of the Sony VPL-U300WZ projector is 4285 lumens, which is 122.4% of the nominal brightness, and the performance is excellent. At the same time, it can also be found that Sony has no imaginary product brightness. What we are going to do next is a color test. In this link, we mainly understand the color reproduction ability of the machine through the difference between the color test proofs and the real shot figures. How does the Sony VPL-U300WZ projector with excellent measured brightness performance perform at this stage? Here is my answer to you. The left is the real sample for the right side of the test sample sheet (the mobile phone end browses the test sample sheet for the real shot) The left is the real sample for the right side of the test sample sheet (the mobile phone end browses the test sample sheet for the real shot) The left is the real sample for the right side of the test sample sheet (the mobile phone end browses the test sample sheet for the real shot) Through the above groups of real shot map we can see that Sony VPL-U300WZ projector focus is clear, the picture shows complete details, color reproduction is more accurate. The warm color in the first picture is better in color reproduction; the figure in the second picture is also delicate and shiny. As mentioned earlier, the Sony VPL-U300WZ projector is equipped with 3LCD projection technology, and color performance has always been an advantage of 3LCD technology. The left is the real sample for the right side of the test sample sheet (the mobile phone end browses the test sample sheet for the real shot) Can be seen in the comparison of four-color graphics, as a product using 3LCD projection technology, Sony VPL-U300WZ projector overall color reproduction is good, no color drift. The user can get a good color experience during daily use. As an educational product, Sony VPL-U300WZ projector in daily use may be the most projection PPT courseware, so after reading the color performance, the author brings you a few local PPT real shot map, Please come and enjoy it with me. PPT effect real shot Measuring PPT effect real shot PPT effect real shot From the above a few shots of the PPT, we can see that the PPT screen projected by the Sony VPL-U300WZ projector is accurate, clear and sharp, and can fully meet the daily needs of educational users. After watching the PPT real shot map, I also prepared for you some of the Sony VPL-U300WZ projector landscape shots, through which you can further understand the machine's color performance. Rich colors and overall saturation Focus is clear, the picture is layered Contrast high detail in place The details are precise and the bird feathers can clearly show The picture is delicate and the seals are clearly visible From the above real shots, we can see that the Sony VPL-U300WZ projector projected a clear color screen, the details of the precise description. From the user's point of view, you can get a good user experience. Editing summary Through the stress test of the day, the author had a very deep understanding of the Sony VPL-U300WZ projector. In general, I think this product has three characteristics. The first thing to say is the sharpness of the picture. Although the nominal resolution of this product is only 1280×800, in the actual evaluation, the author feels that the sharpness of the picture is obviously higher than that of other products with the same resolution. This is mainly due to Sony's "real creation" technology and larger size LCD panels, so the user does not have to worry about clarity. The second thing to say is the brightness of the product. Many of the projections reviewed by the author did not reach the nominal value, either the maximum brightness or the peak brightness. However, the maximum brightness and peak brightness of the Sony VPL-U300WZ projector have reached a nominal 113%, 122.4%, respectively, this brightness performance is no problem even in bright classrooms, and from the side you can see that Sony is not empty Standard. The last thing to say is the color performance of the product. Thanks to 3LCD technology, the Sony VPL-U300WZ projector has a higher degree of color reproduction and more precise detailing. Overall, I believe that in the field of education projection, Sony VPL-U300WZ projector will play an important role.
