20 cm shot hundred ViewSonic ultra short focal home projector evaluation

Traditional projector products generally adopt positive projection and require a certain projection distance. Therefore, it is very inconvenient for small-sized friends. Although laser television can solve this problem, but the expensive price will deter other users. Today, the ViewSonic PX800HD projector we want to evaluate is an ultra-short-focus product that uses a traditional bulb light source and is suitable for small-sized users. Compared to the price of about 30,000 laser TVs, this product requires only about 15,000 yuan. , very affordable. Please follow me with a look. ViewSonic PX800HD home projector standard resolution of 1920 × 1080, contrast ratio of 10000:1, projection effect is still very secure, the machine uses a 240W Philips bulb, brightness reached 2000 lumens. It is worth mentioning that the projection ratio of the ViewSonic PX800HD is only 0.22, which means that it can project a large 100-inch screen at a distance of about 20 centimeters, which is very suitable for small-sized friends. After measurement, the power consumption of the ViewSonic PX800HD is about 283w, which is still more environmentally friendly than similar products.
ViewSonic PX800HD home projector uses 6x speed RGBRGB color wheel, and is equipped with the exclusive ViewSonic Cinema SuperColorTM movie color technology, which can achieve the true color rendering of movies. Really? Please follow me and continue to look down.
The figure above is the objective test result of the ViewSonic PX800HD. If your time is limited, you can use it to understand the product. However, if you want to understand the data, it is definitely not acceptable, so I suggest you review the complete evaluation, savor, and make judgments. Here we enter the evaluation of ViewSonic PX800HD.
Gray and stylish with dynamic appearance ViewSonic PX800HD projector appearance of the main color is white, supplemented with gray in the front, gray and white make the machine look clean and elegant but without losing the sense of fashion. The appearance size of the whole machine is 434×388×153mm, and the net weight is 6.075kg. When it is used at home, it is more convenient to move it.

ViewSonic PX800HD projector on both sides of the outlet area is relatively large, you can quickly send out the excess heat. In the back of the machine is designed with a wealth of interfaces, a reasonable layout. It is convenient for you to connect multiple devices. The operation interface is on the left side of the machine, and the key functions are very rich, so it is very convenient to use.

According to our test, the noise of the ViewSonic PX800HD projector is 67 decibels. This value is slightly higher in similar products, but it will not affect the daily viewing. In addition, the remote control interface of this machine is all in English. , may bring some inconvenience to the use of old friends.

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 where the projector can just distinguish eight gray scales.

Eight gray levels and 13 illumination test points

Two different contrast test methods

data analysis:
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 tests, the maximum brightness of the ViewSonic PX800HD is 1655 lumens, which is a nominal 82%. Generally speaking, this value can reach 90% and it can be said that it is very good. Although 82% of the ViewSonic PX800HD has a certain gap with excellence, there is not much difference.
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 data actually tested, the peak brightness of the ViewSonic PX800HD is 1824 lumens, which is a nominal 91.2%, a little bit away from the best.
ANSI brightness refers to the ANSI test standard. As such, the ANSI brightness reference is more significant. From the actual test data, according to ANSI test standards, ViewSonic PX800HD ANSI brightness reached 1211ANSI lumens, from a digital point of view, ViewSonic PX800HD ANSI brightness is not so outstanding, but for our daily viewing needs, should say enough Now.
Contrast:
In the contrast test, we brought you two data, one is ANSI contrast and the other is FOFO contrast. The ANSI contrast is closer to our daily viewing experience. We used 16 black and white color patches for testing. In the daily video, if there are some very bright or dark pictures, the FOFO contrast level will affect the viewing experience, and the value will be tested by the picture is completely white and the picture is completely black.
Judging from our measured data, the ViewSonic PX800HD has an ANSI contrast ratio of 230:1 and a FOFO contrast ratio of 7125:1. This performance can be said to be very good. There will be strong color contrast and a good picture level in the released pictures. In a place where the color difference is obvious, you will get a good viewing experience.
High color reproduction but overall darkness For the projector, color testing is an indispensable item in routine testing. This project is mainly to understand the color reproduction of the machine through the differences between color test proofs and real shots. ability. Especially when the ViewSonic PX800HD projector is advertised, it is the real color reproduction effect. So how does this model perform in color? Let's take a look at it.
Through the above group of real shot map we can see, the ColorPilot of the ViewSonic PX800HD is more accurate, the color is clear, the focus is clear, basically maintaining the color style of the original picture, but compared with the original picture, the color of the ViewSonic PX800HD slightly Dark, but this will not affect your daily viewing.
In the comparison of the four-color diagrams, it can be seen that the picture color projected by the ViewSonic PX800HD is very positive, and the overall reduction of the four colors is high, and the user does not need to worry about color shift. However, the overall brightness of the color is still a bit dark.
Excellent color pursuit of high-quality user preferences ViewSonic PX800HD this product appearance of gray with the design, looks very stylish and dynamic, can be a good blend with your home environment. The interface design behind the machine is rich, and multiple devices are connected without pressure to facilitate your daily use. However, the remote control interface of this machine is all in English. For those who are not proficient in English, it takes a little time to learn.
ViewSonic PX800HD1080P's clear and sharp picture, and the measured contrast is very outstanding, allowing you to feel a layered viewing experience. However, the measured ANSI brightness of this machine is only 1211 lumens, which is slightly lower than the price of the same product.
ViewSonic PX800HD performs well in color, with a wide color gamut and a high degree of color reproduction. In the ointment is the overall picture is slightly dark, but for the average family viewing, it is already very good. Taken together, the outstanding performance of the ViewSonic PX800HD, especially the characteristics of both ultra-short focus and relatively affordable price, for small-sized users, this machine is a good choice for you.
