Overview:
I believe that for many Acer fans, Acer is no stranger to this projector. I had the privilege of getting a good Acer H7550ST projector on the it168 tester platform. After a few days of experience, I will place a comprehensive evaluation of the product's experience on the top of the article, hoping to do it for you. A reference. Evaluation feelings only represent personal views and are not directly related to the test platform.
Advantages: The first is the brand, the quality of the big brand is trustworthy. Acer is a product that is biased toward commercialization and is still guaranteed as a quality home. The projection distance of 1.5m has made a good progress for Acer. It can achieve a 100-inch projection screen with 1.5m. Perhaps the biggest enemy of the projector is not itself, but the problem of light. Perhaps increasing brightness is the best way to fight light. The brightness of 3,000 lumens is obviously stronger than other projection products. 2D is equipped with 3D images. Although it is not new technology, it is better than nothing. It supports multiple 3D formats to meet users' needs. Built-in 20W speakers, although there are still gaps and professional-grade audio, Acer is also considered a good idea to take DTS Sound? With Acer TrueHarmony theater sound effects. Supports Wireless HD and Chromecast wireless projection functions.
Inadequate: The price may be a pain point that many netizens think. In the past few days of experience, in addition to the advantages, there are still some shortcomings and deficiencies. The first is that the focus needs to be manual, after all, there is now an auto-focus projection product coming out. So manual is still a little tedious. In terms of heat, the huge projector, at 20 degrees Celsius at room temperature, has a maximum temperature of 60+ and stabilizes at about 56 degrees Celsius. Of course this temperature is only in the heat sink near the bulb. The temperature performance of the side auxiliary cooling vents is still very perfect. Although support WirelessHD and Chromecast wireless projection capabilities, but need to buy plug-ins to achieve it, it is obviously a pit stop money. Million machines Do these plug-ins cannot be directly integrated into the machine? Compared to domestic smart projectors, the Acer H7550ST projector is not smart. There is no dust-proof device on the heat-dissipation hole, and it will take a long time for the aperture to feel the dust on the fan's blades.
Comments: Although the Acer H7550ST projector has some deficiencies, but the projection device, after all, is a visual device, after all, then the projection of the degree of reduction is the projector should have the quality. 3000 lumens can be watched normally even indoors, and the color reproduction of the Acer H7550ST projector is very good. Simply evaluating the Acer H7550ST projector can be described as very good. Of course, today's devices are all about smart times. If the acer H7550ST projector can integrate some smart modules, it will attract more home users to choose. Even integrating a TV box is very good. If you are a pure movie talent, then the acer H7550ST projector is a good choice for you. I believe that the display will not disappoint you. If you have a veritable Acer powder, then this projector will not disappoint you. If you are pursuing the combination of intelligent network and projector, it is clear that Acer H7550ST has not yet reached your needs.

Unpacking:
When it comes to the product, the packaging of the acer H7550ST projector is also unique, revealing a strong commercial flavor. Inside the box, you can see the two 3D glasses that you sent at first glance. The glasses are covered with a "computer bag" with bubbles, which is the protagonist of today. In fact, the author and most of the netizens are the first to learn that Acer’s product is a computer. There is not much understanding of the projector. Then there is no more information on the history of projectors on its website. It is clear that Acer has laid the foundation for the last stable international brand in the minds of users after many transformations.
Come back to us to talk about the product out of the box, receive the courier found no external box, we can see that the macro (acer) H7550ST projector is full of compressive and anti-lost information on the packaging. Sure enough, inside the outer packaging there is a computer-like package in it, in the computer bag on two 3D glasses, it is said to be sent. The two apparently are the time for the young couple to spend time together.
The packaging design of the "computer bag" is obviously the ideal effect obtained through repeated practice by Acer. From a different perspective, this design is very practical. The business person has an important meeting to ensure that the projection equipment is perfectly safe and generally carries reliable equipment. It happens to be such a package, so that the bulky Acer H7550ST projector has a portable experience. Yes, this bag is compressive and dustproof and portable. This design is still worthy of many manufacturers to learn.
Acer H7550ST projector accessories are not too many, but the paper is indeed a lot, mostly in English, the instructions are also very thick, in fact, only two pages are the instructions and the like. Accessories include: power cord, VGA cable, CD-ROM, remote control, battery, manual, 3d glasses, etc., HDMI cable is not seen in many accessories, of course, Wireless HD and Chromecast wireless projector modules are not... Sex testing has a big obstacle.
product details:
Get Acer (acer) H7550ST projector first evaluation of the appearance, is able to hit a perfect score of 9.5 points, lightweight body, three super large heat network design or people feel that the heat should have a good performance. Silver imitation metal texture, milky white panel, is also breaking the style of Acer's solid color design.
Two built-in 20W speaker units can be seen through the heat from both sides of the acer H7550ST projector. The interface extension of H7550ST may be the first impression of seeing Acer H7550ST projector, a lot of interface expansion. Designed in the entire back of the machine, according to the picture below, we can see that the machine provides rich HDMI, VGA, S-Video, Video, Audio, Video, Mini-USB, RS-232 and 5V-SUB power supply Port resources can be easily connected to a variety of different devices at the same time, simply switching signal sources to meet the needs of multiple applications for home and business users.
Acer H7550ST projector in addition to the fuselage with a button is also equipped with a remote control, remote control and projector tone is still quite collocation, the button is not designed to be very simple, but the design is a lot of buttons represent a different signal source Switch between. From a simple point of view, the keystrokes are a bit more tedious. From a practical point of view, this kind of design is much faster. There are advantages and disadvantages. The H7550ST projector is a relatively short-focus product in the Acer series, so most of the time we can place it on the coffee table in the living room. But what is interesting is that from a single contact pin, only two can be adjusted and the other one is fixed. This design, how can I also think of no advantage. Maybe just fine-tune it.
Perhaps Acer has long smelled the future market will be combined with the intelligent module, H7550ST supports plug-in expansion, there is a special piece of paper in the manual of the paper, although it is in English, but there are certain basic users through the pictures are Can understand this is a disassemble diagram. There are three Phillips screws above the expansion interface that can be opened to open the top cover of the machine.
When opening the top cover, it is necessary to note that after loosening the screws, it is necessary to use a certain external force to open the top cover. After opening, you can see the position of the light head marked with a yellow warning word, and the part that prompts you to remove the card privately is Can not be guaranteed. So curious users still don't want to open it in private. There is a small slot in the upper left. There is a USB connector and an HDMI interface. This is the expansion port. At present, this interface can not only directly connect the MHL cable. It is convenient for users of Android system to implement mobile phone projection, and can also connect wireless modules to achieve wireless projection operation. Do not know if the future is able to develop more plug-ins to support the expansion?
One year later, at the end of 2014, Acer released a home theater projector model: H7550ST. This is full of Acer's latest understanding of home audio and video since 2014, the new concept of putting together all the latest technologies, all infused into the Acer H7550ST this product, a new interpretation, a new innovation. The real projector is popular among domestic families this year. The combination of intelligent and traditional projectors really set off the climax of this home theater. Obviously, the Acer H7550ST projector is a bit of a rainy one. Perhaps because the design a year ago did not combine the Acer H7550ST projector with an intelligent network, but the acer H7550ST projector has a cleverly designed wireless plug-in to solve this problem. Unfortunately, I didn't get the wireless module. I wasn't able to combine the TV box and the projector together to realize the network intelligence. Since there is no such module, there is no way to test it. After the inquiry through the Internet, it seems that the wireless module also only supports the wireless projection function. And not too smart design in it.
Performance Testing:
The projector is first seen as a projection effect, and the author is also considered to have used several projectors. The first high-end projector like the Acer H7550ST projector is still the first time to experience it. The first thing to turn on the projector is shock. . The built-in exclusive Acer ColorSafe II next-generation imaging technology, which provides dynamic RGB color correction, effectively reduces the color deviation of images after prolonged use, presents high color accuracy and color space, and has stable projection quality; built-in Acer ColorBoost 3D imaging technology , The use of 6 color wheel with exclusive coating and color segment control to enhance the color saturation of up to 30%, to ensure that users can get a clearer and more realistic and bright saturated color visual effects. H7550ST projector supports Blu-ray 3D projection, can display 144Hz/24p high image quality, also supports 2D to 3D image technology, through 3D glasses that is a three-dimensional plane, real-time enjoy dynamic visual effects. No matter what the official said, we might as well test the H7550ST with the standard of the test monitor.
The display through the test chart H7550ST is great, but because the camera takes a second shot, it is somewhat visually misleading. Through the author's observation of the scene is: the color components gradually become brighter from left to right, the color is clear. The third author in the notebook is difficult to see the 10 lines of "SK Gaming" words (of course, the author of the book is more general friends.), H7550ST can see 10 lines, indicating that the display is very good. If you are willing to download this map to try your own computer or projector.
Real shot color reproduction proof:
Real shot color reproduction proofs;
Since as a home projector, watching a 3d power supply is bound to have a lot of needs. Acer's exclusive Acer ColorBoost3D technology restores more details for 3D color reproduction. In actual experience, the glasses feel good after watching a movie (about 2 hours). There is no great feeling of pain. The degree of picture reproduction is relatively good. Although it supports 2D to 3D source, it is recommended to download the Blu-ray 3D source to be able to experience the shock of the large screen.
Acer H7550ST projector has a hard and soft support, and after the adjustment of the color, performed very well, there is a large screen clear sense of the cinema. I have to say that I have a built-in sound system. I have really good sound performance. I wanted to record a sound, but the recording equipment is not ideal. But what is certain is that this performance is good for the built-in speakers. Acer H7550ST projector can get 95 points out of 100 points from the playback and audio effects alone. It's perfect as a commercial, but as a home you need an external playback device. This obviously has to add extra cost.
In the last test, the temperature was tested after 4 hours of playback. The temperature of the heat radiation network of the spotlight was about 55 degrees Celsius, and there was no abnormality in the temperatures on both sides. After the Acer H7550ST projector starts up, the temperature will quickly rise to 50+ and then stabilize at about 55 degrees Celsius. If this and the cooling effect of the projector and the author of the book with 50 minutes to close the cooling of the traditional products, the Acer (HX5050 projector) performance is much better. The issue of not stopping at all appears. However, at room temperature at 25 degrees Celsius, the temperature reached 55 degrees Celsius, then the temperature of 30 + summer will not exceed 60 degrees Celsius? Is there a thermal alarm? This can only be tested during the summer. However, the heat sink of the Acer H7550ST should be able to survive. After all, brightness is 3,000 lumens. This is many times the traditional projector. Basically, you can feel the effect of a movie theater without deliberately hiding all the outside light.
Maybe you can't directly feel the effect of 3000 lumens through the above evaluation content, then you can see the effect very clearly through the above diagram. Explaining the above picture shows the effect of two projectors simultaneously. One projector has only about 800 lumens. It is the projection effect of Acer H7550ST. The small lumen projector is actually playing a war film. Basically not very clear. It can be seen that high lumens can effectively solve the dilemma of daytime projector watching movies.
Adapt to the scene:
It may be that traditional commercial projectors have certain restrictions on the focal length, while the Acer H7550ST projector supports 1.5-inch projection of 100-inch display, which is obviously a short-range focal point. This also just shows that the Acer H7550ST projector is positioned home. For the users of the big screen shock effect, the Acer H7550ST projector is the natural choice. Support 2D to 3D and MHL transfer function, although 2D to 3D can solve the problem of 3D film source shortage, which can provide a good solution for 3D fans, but for most users, it is not currently the main projector. Features. The MHL transmission can be easily connected to an Android phone and a projector to realize integrated information sharing between a small screen and a large screen. This point is to make up for the lack of an integrated TV box module and is a relatively new attempt for home users. Although the H7550ST has a built-in 20W stereo speaker, it is recommended to external speakers for the perfect home theater experience to meet the extreme needs. Of course, a good playback device is also in demand. After all, the H7550ST offers high-quality projection. To achieve top-level results, every aspect needs to be considered.
