Appearance: Significant difference in "personality"
The first impression is very important, the projector is no exception, the appearance of the fashion makes the user more eager to understand, placed in the home will not be unexpected. However, due to the different priorities of various manufacturers, the performance is too homogeneous today, the appearance is still a great look, from the appearance we can also feel the "personality" of the manufacturers behind them.
Polar Rice T1 early impression: excellent material exquisite workmanship
Polar meters T1 is a new product released by Rami Technology in July this year, positioning "life winner", as the name implies is created by high-end users, so the appearance of a great deal of effort. A guqin-style design was adopted. The overall material was metal and black walnut. The addition of black walnut from North America weakened the cold metal feel. The overall shape is different from the traditional square-shaped design concept of the projector. The top is designed in an arc shape to neutralize the spirit of the metal. It is said that due to the use of natural black walnut, almost no two identical T1s can be found. Weight: 23.5 kg, three-dimensional: 836 x 396 x 174.5 mm.
First impression of Acer VL7860: The lightest and smallest 4K projector
The Acer VL7860 debuted at IFA 2017 in Berlin, Germany, and was hailed as "the lightest 4K projector." The overall use of silver and white colors, fashion is simple, lightweight is the bright spot. Weight 8.5kg, three-dimensional: 458 × 289 × 157 mm.
BenQ W11000 early impression: tough guy
The BenQ W11000 is a product released by BenQ last year and is one of the earliest 4K projectors. BenQ has always been the main brand of technology, so it is still a bit too monotonous in its shape design, and the traditional projector has a strong atmosphere. Weight: 14.8 kg, three-dimensional: 470.7×224.9×564.7 mm.
Summary: From an aesthetic point of view, the Titanium T1 is slightly better than either material or workmanship. However, just as we have just mentioned that the manufacturers behind the appearance reaction products, manufacturers such as Acer and BenQ, whose main technologies are weakened to a certain extent, are understandable.
Brightness, contrast test
Projector basics: brightness, contrastDue to the imaging principle, the image quality of the projector is affected by the actual attributes, and must reach a balance. The prominentness of a single attribute does not represent a good image quality performance. In the following, we will conduct an objective comparison of the products to the participating products, find out the slight differences between products, and re-analyze the positioning. Allows users to intuitively understand the properties of new products, technology applications and market overview.
Our test of the projector is mainly conducted through multiple angles such as brightness measurement. Due to different environments, users should take into account their own playback environment and factors such as the influence of external light. Our tests will also minimize the error. You provide objective data for reference only. Brightness, fofo contrast, brightness uniformity.
ANSI brightness is the optimized brightness, which is the brightness of the projector with the best expression of the screen. The reference value is very high. Here also to explain, we do not do the maximum brightness test in this Hengping, because in the normal use when the brightness is turned to the maximum when the screen cast color can not be seriously watched, practical use, few people will use the maximum brightness to watch, There is no reference value.
ANSI contrast is also optimized for black and white contrast when the picture performance is the best. Similarly to brightness, the maximum black and white contrast is also of little practical significance. This is also why we often say that the selection of projectors should not be confused by a single attribute. Only when each attribute is more prominent and balanced, can it bring the gain effect to the actual picture, otherwise it is just a gimmick.
Working status: power consumption, noise and temperature testAt present, 4K projector prices are generally high in the market, and the majority of purchase users use professional enthusiasts to play home. Such users are very concerned about product details. Noise and heat dissipation during the use of the projector are inevitable and can only be controlled through technical means. Try to reduce it. In this Hengping we tested the noise, working temperature, and power consumption of this product.
From the test results, the three machines are customized for professional users, and the noise index is about 55 decibels, which is basically negligible and will not affect normal viewing. The operating temperature is around 45°C, and the extremely good T1 performance is particularly excellent, reaching a staggering 39.5°C. The power consumption of all three machines is more than 300W, and the average power consumption is 335W/hour.
Tricolor testThe first step of our color test is to simply look at the projector's recognition of the color transition and the general accuracy of the color. We will also compare the different colors again in the later tests.
In fact, in all colors and sample tests, we must consider the color accuracy of the output and the output. There must be errors in the color of the sample, which will be affected by the camera and the color of the reader's display. At the same time, each person understands the color accurately. Different, there is no objective standard, so our comparison test is only for the user's reference, and gives the smallest error.

Summary: In terms of color, we have selected RGB three-color samples and color oversample test, only for comparison. The three machines have excellent color reproduction in color testing, and the colors are overly smooth.
4 quality contrast
Comparison of actual qualityWe used a human skin color test chart for performance to compare HDR's nebula and 4K video. The sample was taken using the same device and we shot in the same environment. Through the actual shooting samples, we can clearly feel the quality of the machine between the style. Here we would like to thank Extreme Technology for its 4K test video.

Summary: The actual test results of the three machines are surprising. The outstanding brightness advantages of the T1 meter are obvious, the colors are gorgeous, the picture is clean, and the layers are rich. Acer VL7860 color display accuracy, rich layers, clear details. BenQ W11000 insists on color-based, full-color picture, high degree of reduction, is the brightness is low, the whole picture is a bit dark.
Hengping summary
4K brought the projector into a brand-new era. The quality of the picture has been improved by more than one grade. The actual measurement results of the three machines have fully proved this point. One of the biggest obstacles to the popularity of 4K today is price, and the retail price of tens of thousands of people scares away many users who come and see. However, it is surprising that user attention is getting higher and higher, which also indicates that in the background of TV stagnation, users are based on finding new visual stimuli points, so the 4K projection screen will inevitably become the core of home display. After the price optimization, the market is about to usher in an outbreak.
