Primers
At the end of the year, major companies will hold a variety of annual events, and the prizes at the annual meeting are also varied. This year, the author had a chance to burst his luck. He was angry at an acer V7500 home theater. However, as an ordinary working class, the house is not so big. Can a home theater such a tall thing really be built at home? With this question, the author started a journey of home theater construction.
Product research
In the impression that the projector should be a big device, and the installation and debugging are complicated, but from the moment I see the box and take out the host, I think this simple and stylish appearance may really become a member of the home appliances.
What features of such a home theater-class projector can achieve, but also how to achieve high-definition results? Then the author inquired about the relevant parameters of the acer V7500.
The acer V7500 projector is designed for home theaters and supports 100% sRGB standard color gamut for precise color projection. Color purity technology can reproduce richer and purer colors. With RGBRGB 6-color segment color wheel and unique light source control technology, a wider color gamut can be obtained while reducing the rainbow effect. At the same time, acer's latest LumiSense+ technology has also been added to automatically adjust better output results based on the projected content and ambient light. The cable storage box is built into the machine, and the lens design is easier to install and use in the middle position.
The main parameters are as follows:
1. The acer V7500 uses a wide format mainstream configuration with a mainstream 1080p (1920 x 1080) 16:9 ratio.
2. Ambient light sensor: With the ambient light sensor, the V7500 can automatically detect the ambient light conditions. LumiSense+ computer chip will automatically adjust the output brightness and effect according to the detection situation.
3. Content-aware system: In addition to adjusting according to the ambient light, the actual projected content will be analyzed and the most suitable projection scheme will be adjusted.
4. Optimized 6-segment color wheel design, equipped with RGBRGB 6-segment color wheel, combined with red, green, blue, red, green and blue color wheel, multi-waveform and unique software engine light control technology, colorpurity produces a wider range of 72% NTSC color area. Produces a purer, richer color without compression.
5. Advanced Light Source Technology: Provides a high contrast dark field effect of up to 20,000:1. With acer's exclusive ColorSafe II technology, dynamic RGB gains are used to enhance color display and extend the life of light sources. Lamp life is up to 7000 hours.
6. Extended features: wireless projection technology, quarter-screen projection, mirroring, and WIHD HD module wireless connectivity support.
After understanding the detailed features of the acer V7500, I even increased my love for this projector, thinking about how cool it is to watch a movie at home. Let's play with it carefully.
The front of the projector gives an elegant feeling. The lens is placed in the middle. The built-in 10W speakers are on both sides of the lens. This high-powered speaker can provide external speakers without external speakers, but it may be for audiophiles. This kind of sound quality can not be met, but for emergency and light audio and video enthusiasts, this design is certainly better than nothing, especially in the absence of speakers, the speaker can also be concentrated in the body, it is also a good idea . However, I will use other external speakers to improve the sound quality in the later construction process.
After opening the lens cap, you can see that the lens is indeed a big eye.
The outside of the machine adopts a picket fence design. The figure below is the left part. The appearance of the projector is similar to the cooling part of the projector. The replacement of the light bulb is also performed from here.
The right part of the projector, you can vaguely see the inside of a variety of interfaces, this design is different from the projector I have seen before, I feel that this makes the overall sense of the whole stronger.
At the rear of the projector, there is an anti-theft lock and a removable cable port that can be accessed from there if the cable is placed horizontally.
It can be seen that the keys of the machine are mainly concentrated in the rear.
The key part, which is also a simple style, adopts a nine-grid typesetting design, which focuses on all the operations of the body. There are status indicators above the keys.
You can see a large row of technology logos on the right front of the machine, including Nvidia 3DTV PLAY technology (outside of stereoscopic images), as well as Full HD 1080, HDMI, and DLP.
In the lens part, the function of each part can be known through the English logo next to it. The manual focus and zoom design is adopted. The Lens Shift vertical shift function is supported. The point provides great convenience when placing the projector, even if the machine can be placed. The height can not be precisely aligned with the center of the screen, Lens Shift can also be used for vertical movement of the lens, so that the projection screen can be aligned with the center of the screen to get the largest size of the projection screen, personally think this is very useful for home, after all, sometimes at home It is impossible to be perfectly perpendicular to the wall.
The bottom of the machine is equipped with three adjustable foot seats. After the lower right corner is removed, the housing of the interface part on the right side of the machine can be detached, and the wires can be conveniently accommodated in the wire.
The V7500 has many interfaces, including two sets of HDMI, one of which also supports the mobile device's MHL function, which allows MHL-enabled mobile phones or tablet devices to transmit video and audio information to this projector via wire, and project large-size images. For those who like to enjoy video games on their mobile phones or often use mobile phones to take pictures and videos, this feature is very convenient. At any time, you can watch images stored on your mobile phone on a large screen. You can also instantly double the chance to play games. At the same time there are analog signal input and output, 3.5 audio input and output, 5V DC output, 12V DC output, VGA signal input, RS232 and mini USB interface, although some interfaces may not be used, but it is better than nothing If you need to use it on any day.
At the same time, it should be mentioned that the V7500 can use the wireless projector module provided by acer to easily achieve wireless projection. Unfortunately, this accessory is not configured, or it can simplify the cable. Seeing the HDMI interface, I checked that the V7500 can also achieve high-definition wireless connectivity through the WiHD HD wireless transmitter.
lens cap.
You may find that there are two small dots on the right side of the lens. The ambient light sensor described in this official introduction, the VV7500 can automatically detect the ambient light conditions. LumiSense+ computer chip will automatically adjust the output brightness and effect according to the detection conditions. I will also test this feature during the build process, which is very important for home projectors, and no one will always turn off the projection of the lights at home.
Of course, the V7500 is also equipped with a very compact remote control for ease of use.
Design of the plan
The author's home is not large, because the living room has already placed the television, so can only build the home theater in the study room. Since it is the first time to set up a home theater system, we first need to use existing computers and speakers. The computer uses the T450, and the speaker is the newly purchased BOSE SoundLink Mini speaker II Bluetooth speaker.
The layout of the author's study is as follows:
In order to create an area for projection, a wall of bookcases was moved to other rooms. The hard work added a small table for the placement of projections. The layout after migration was as follows:
Put a place behind the projected table so that you can move the computer chair over in the future. You may also consider adding a sofa in the study later.
The connection of the equipment is relatively simple. The notebook is connected to the V7500 projector via a VGA cable and the speakers are connected via Bluetooth.
Construction process
With the previous program design, the connection is very easy, as shown below the device can be placed on the commissioning.
After the power is on, there is light coming out of the lens.
On the left side you can see the internal light bulbs and hot air blowing out.
Power on light is red.
Turns blue when turned on.
The initial boot lens is not on the focus, with the front focus knob is very simple to adjust it, the rear zoom knob can adjust the screen size, roughly looked down, you can zoom 1.36 times the look.
After debugging, ready to turn off the light test.
Testing process
The first step is to adjust the resolution to 1080p, and the image will be projected onto the wall.
Then the static image is used to test the quality of the image. You can see that the color purity is high, the color is more real and rich, and there is no problem of color deviation. In any case, the screen color of the T450 is better.
The static picture effect is very satisfactory. How about the effect of playing the movie? The author chose several films for testing. From the test results, the color aspects are consistent with static displays without any problems. There are no issues such as any streaks in the dynamic aspect, and the screen response is quick and accurate.
In order to increase the difficulty, I chose the 1080p version of "TimeScapes", high-definition picture and high light difference picture of the general display are difficult to competent.
In the sky, the V7500's DynamicBlack technology has a powerful role. The high contrast dark field effect capability of up to 20,000:1 makes every picture perfect.
Through the remote control to enter the operating menu, you can see the adjustment options are very rich, but the interface is very simple, basically hands will. You can see the first option, LumiSense (default is "Automatic Bright" mode), which is the automatic adjustment of the output brightness and effect through the ambient light sensor detection environment mentioned earlier. Below are the adjustment options for color mode, wall color, brightness, contrast, color temperature, and more.
The following two pictures are taken with the room lights on and off respectively. Basically, the difference is not visible (I don't say that we certainly don't know which one is the case). LumiSense technology has played very well on this. Big role.
Note: The first one is off and the second one is on.
The second page is the adjustment page of the screen position, and the options are quite rich.

The V7500 also supports 3D images, and 3D projection effects can be easily achieved through 3D eyes. The 3D mode can be switched on the menu, and the 3D refresh rate can be adjusted. The 3D Blu-ray source can be used to easily achieve 24p 3D cinema effects.
The last one is the operation menu language selection page.

end
At this point, using acer V7500 to simply build a home theater is complete, the first feeling is a little excited, so simple to enjoy the feeling of cinema at home, this is called life! Through the initial use of the acer V7500, it also has a certain understanding of its performance, 1080p resolution is sufficient to provide a clear picture quality, ambient light sensor can provide the greatest environmental adaptability, RGBRGB 6 color segment color wheel can provide pure rich The color and dynamic black level of DynamicBlack provide the possibility of rendering high-contrast dark-field image quality. At the same time, technologies such as wireless extension and mirror display provide more playable space. In short, individuals think that this projector performs well in a balanced manner. The performance is also strong enough, and later watching movies at home has finally fallen. In the end, I remind everyone that audio-visual fever is a complete bottomless pit. It has a huge investment and a lot of gimmicks. When you indulge in a world of sensuality, you must not confuse your mind or return to the real world! Real life is the king! I wish everyone in the home theater fever on the road can take detours to buy their own audio and video equipment.
