In the past, projection products were generally used only in commercial settings such as schools, business offices, and lectures. With the development of science and technology, now when people talk about projection, it is easier for people to think of the use in the home field. Indeed, many families now use projection as their primary entertainment terminal. So, what characteristics of projection are the most important in home situations? The author believes that in addition to the compact body, the more important is the performance of the screen. Today brings us a PX725HD projector from ViewSonic, which has 1080P HD resolution, 2000ANSI streaming brightness and cinema-level color standard 100% Rec.709 color gamut, and then take a look at my experience! 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
As a face value control, in the purchase of any product, the appearance must be the first condition, ViewSonic PX725HD projector uses a white body design, simple and reasonable layout design and avant-garde big eyes, the overall exudes young, stylish breath. In addition, the appearance of the PX725HD is also a wild type and can be used in various home environments.
The traditional projector believes that you have seen a lot of it. It is a big block and the machine is destined to keep it fixed in one place. From the perspective of size, the ViewSonic PX725HD projector is obviously a lot of small and exquisite, 348 × 234 × 107mm measurements plus only 2.94KG of weight, giving it more portability, the use of the scene can also be diversified .
The frontal design of the ViewSonic PX725HD is simple, with the three birdies logo of ViewSonic on the lens.
On the top of the lens is a manually adjustable focus knob. The two knobs control the size and focus.
The top of the ViewSonic PX725HD is designed with simple physical operation keys, even if the remote control is not around, it can also perform simple operation on the projector.
As we all know, the higher the brightness of the projection, the higher the requirements for heat dissipation, if the heat treatment design is not handled well, it is easy to cause damage to the machine. ViewSonic PX725HD has designed a large area of ​​exhaust vents on both sides of the fuselage, which has good heat dissipation performance. At the same time, noise control is also good.
In order to make the desktop more stable, ViewSonic PX725HD has designed three silicone mats on the bottom of the camera body. While it is firm and stable, the anti-slip effect is also very significant. Even if the desktop has a certain slope, it can be stable as before. Of course, if you have the need for lifting, the relevant screw holes are also reserved at the bottom, and you don't need to switch and install it.
In addition, on the floor mat of ViewSonic PX725HD, a mini bracket function is also designed. By simply turning the knob, the tilt angle of the machine can be easily adjusted. In combination with the trapezoidal correction function, it can be used in most scenes.
To expand the interface, HDMI, VGA, and tri-color line output should be available, basically can cover the output of traditional TVs, computers, notebooks, game consoles and other devices.
Here we take a look at what the ViewSonic PX725HD comes standard with, in addition to the host, remote control, power cord, manual, but also traditionally attached a color performance test report.
As for the remote control, the biggest surprise for me this time is that it is equipped with a backlight, which can be used in a dark environment. The remote control backlight can greatly improve the phenomenon of inadvertent touch. The remote control is full-featured but it is all in English, and it may be a bit obstructive to use.
What parameters are most concerned about buying a projection product? Needless to question, of course, is the brightness, due to the special nature of projection products, brightness directly affects the screen shot brightness, sharpness, color performance and a series of display-related elements. The simple explanation is that the higher the brightness parameter, the better the picture performance. There is usually enough 2000 ANSI lumens for home projectors, if they are dual-use. It is best to choose a machine with more than 3,000 lumens. So, how exactly does the ViewSonic PX726HD perform? Then use a series of real shot tests to tell everyone.
"See light dead" should be the biggest pain point of the projection product, the principle is very simple, we go to the cinema to see why the lights off to see that the projection is the same, only in the dark light environment can be used to achieve the best results, and Light interference has a certain degree of influence on the picture, especially those micro-projections with only a few hundred lumens that cannot be watched in the light or during the day. The author conducted a real shot test of the ViewSonic PX725HD in three scenarios: daytime, night light, and black. From the results, during the day and in the light, the overall picture of the picture is a little whiter, but it is difficult to see without contrast. , It is recommended to use the curtains during the day. As for the effect under the dark scene, the colors should be more pure, and the contrast is high and the effect is most ideal.
In addition to streaming brightness, another big selling point of the ViewSonic PX725HD is its good color performance. The 100% Rec.709 color gamut can be said to have reached the cinema display level. This is a simple introduction to the Rec.709 color space. The Rec.709 color standard is the international standard for high-definition television. All major TV stations follow the Rec. 709 color space standard when shooting, producing and playing HDTV programs. Rec.709 is also the hardware industry standard for shadow bars.
For the user, choosing a projector that supports the rec. 709 color gamut can bring the same color as the videographer saw. The intuitive change is more brilliant and clear color.
I use a few test monitors, TV professional test chart to make real test, color performance, red, yellow, blue, green and other color performance is pure and beautiful, brightness is also very high. There are grayscale tests, black and gray filter is clear and natural, especially black is very pure. The entire test feels like testing a TV without blurring and color cast.
More real shot pictures
â–²As you can see from the above real shots, the ViewSonic PX725HD performs very well in terms of screen brightness, contrast, saturation, etc., and the details of light and dark are layered, and the definition is also very high, even if it is an 80-inch large screen. It can also be extremely sharp.
ViewSonic PX725HD has a throw ratio of 1.5~1.65:1. It can project an 80-inch screen in only two meters. The conventional living room can easily shoot a hundred-inch screen, and as long as the space permits, it can be bigger. This point is that television can't compare. Can you remember before a certain celebrity sunned a 100-inch TV? The price is not expensive, and the handling fee is extremely high (the door cannot be moved in and can only be lifted from the balcony by a crane). The small and lightweight ViewSonic PX725HD is flexible enough to make any scene a giant movie theater.
In the living room, use the ViewSonic PX725HD to project a hundred inch movie screen to see "Chasing the Dragon."
Through the remote control, we can set some basic parameters of the projection, such as signal source selection, 3X rapid response switch, color mode, display band, etc., according to their own needs to control.
ViewSonic PX725HD provides the brightest, sports, standards, games, movies and other color modes. From the motion picture, we can see the picture performance under various modes. For the author to see the movie mode (Rec.709), the best color performance, Best for everyday use.
If you are a novice user, no matter how you place the projection position, you always feel that the screen shot is not positive enough, and the deformation is terrible. Then, trapezoidal correction is absolutely your life-saving straw. ViewSonic PX725HD supports +-40 degree trapezoidal correction technology, unfortunately does not support horizontal trapezoidal correction. , so I can't shoot sideways.
I remember that when I was young, I was playing in front of a small color TV that was 10-20 inches in size with the younger partner. Every time I didn’t fight for 300 rounds, I wouldn’t give up. Nowadays, it is no longer known how many generations have been updated, and on the rise, even the ViewSonic PX725HD is playing the latest live 2018. The election is still the favourite Milan, and the Champions League is not in a big fandom under the big screen. Another feature of this projector at this time is the "3X rapid response". This feature allows the projector to have three times the response time of a normal projector. The actual experience can make the picture more relevant.
The family members gathered together to drive the cars together and play together. They were chasing the goddess/goddess together to create an atmosphere based on the ViewSonic PX725HD.
To sum up, the ViewSonic PX725HD has a small and exquisite appearance, white body, looks very comfortable and able to HOLD live in a variety of home environment. Picture performance, thanks to 2000ANSI lumens, 1080P physical resolution, and 100% Rec.709 color space support. In addition, a wealth of expansion interfaces, good heat dissipation, remote control with backlight, etc., all add a lot of color to the projection. As for improvements, horizontal keystone correction is even better. If you have a need for projection quality, brightness, and color, the price of the ViewSonic PX725HD at 4000+ yuan is worth recommending.
