Foreword: 
In recent years, smart micro-investment products have sprung up and broke the television-centered viewing mode. Although the development of television is also rapidly advancing, the volume is too large and the playback size is limited. The cost of the big screen is to spend high prices. The micro-projection product has made up for these drawbacks of TV products by virtue of its small size, large size, and low price. Cool LeTV, as a well-known projection manufacturer in China, has rich accomplishments in product research and development and innovation, and it is highly appreciated by consumers. Cool music as Q7 is its new product, known as the world's brightest handheld micro projection, as the 2017 opening, surely there will be more highlights worth us to look forward to, then follow me to find out about it.
Unpacking:
Let's take a look at the packaging of cool music as the Q7, using the carton packaging style, the overall style is very simple, white-based color matching and the cover of the color letters Q phase, add a lot of reiki. The side of the box is marked with the English logo, product serial number and so on.
On the back of the box, details about the Q7 Standard Edition are provided. Scan the two-dimensional code above, you can also pay attention to the official WeChat public number, in the above can not only focus on the latest product developments, but also when faced with problems, face-to-face communication with customer service, in order to better solve the problem.
The first time we opened the box, we could see a sponge pad covering the machine. This design reduces the friction between the lid and the top of the fuselage. After taking it off, you can see the protagonist who is going to introduce it today. It is embedded in a sponge pad and it is very tight. It is very well protected during transportation. The accessories are placed below and on the left side of the mainframe. The layout is reasonable and the space is well utilized.
Do not look cool music Q7 compact, accessories are very rich, except the host, comes with a HDMI HD cable, mainly used to connect televisions, TV boxes, or computers. Also comes with a clever folding stand, a modular power adapter, of course, the product manual is also indispensable, detailed description of the host interface name and use, as well as built-in system features and methods of use, as long as the user in detail Reading can be easily started. The attached power adapter is described in detail here. The specifications of the power adapter are: Input 100-240V ~ 50-60Hz 0.7A Output is 12V = 1.5A. According to the above information, the power adapter equipped has a wide range of application and can be used globally. The Chinese civil lighting power supply voltage is 220V, while in countries such as Japan, 110V, the switching power supply can work normally within the target range. The output power can be kept constant. And the plug of the power adapter adopts a combinable design. By changing the plug, the plug requirements of different countries can be met.
detail:
Cool music Q7 appearance as a square, four corners do circular processing, material used in the popular polycarbonate material, although it is a plastic material, but in the feel, hardness, pressure resistance is indeed very strong. At the top of the fuselage, a transparent acrylic material is also designed with a high face value. As cool music Q series, it has a compact and convenient features, the same size as a mobile phone, carrying no pressure.
The overall color of the body is white, which looks very elegant. The front of the fuselage, the left side of the projection lens, the right side of the bar-shaped hole for the heat outlet, through the hole, you can clearly see the inside of the copper and aluminum heat sink, the material is still very solid.
All interfaces are designed on the back of the fuselage, so that the appearance looks more tidy. The interfaces are not rich, but they are good enough. From left to right are the DC power jacks, hdmi HD sockets, USB 2.0 jacks and headset jacks. For a handheld projector, everyday use can't be avoided.
The physical buttons are focused on the left side of the fuselage, from left to right are the power button, the small round hole is the reset button, the two buttons next to the right are the focus keys, if the screen is not clear, you can focus Press to focus. The buttons adopt a long strip design, and they have also been chrome-plated. This is matched with the white body, which is very coordinated and has more texture. The key path of the buttons is shorter and the feedback is good.
The top of the fuselage covered with a layer of transparent acrylic material, 2.5D arc design, as white as crystal clear, in his hands, skin feel good. The centered location has been designed with a red circle, which is particularly noticeable on a white body, just like the red in the snow. In fact, this is a sign that is easy for the user to do. When the user needs to call out a virtual button or confirm the options, they need to click here. Because this cool music as the Q7 is the standard version, does not support the remote control, so all the menu operation buttons are designed here. Users can not only adjust the volume, but also set menu options and change programs. Compared to the remote control, it is cumbersome. On the right side of the red circle, there are 3 indicators in parallel, it is used to display the power, users can observe the current situation to understand the remaining power.
The bottom of the fuselage is still clearly laid out, the openings on the upper and lower ends are air inlets, and the centered ones are fixing holes. At the bottom of the corner is also designed with non-slip rubber mats, white color, and the fuselage is very good. In addition, the back of the fuselage is also affixed with a parameter label on the product. At the top of the label, a small stand is also designed, which can still be satisfied in a relatively simple environment.
Experience:
The minimalist features of Cool Music Q7 Standard Edition are not only reflected in the appearance, but also reflected in the built-in system. Built-in Linux operating system, unlike other projection products, Cool Music Q7 Standard Edition can only be used as a projection medium However, there is no independent UI, just provide such projection modes as EZcast, Android with screen, Apple Wired, HDMI and USB, which must be interconnected with external devices in order to exert its projection effect.
The contents of the setup menu are also relatively simple, providing only language settings, firmware versions, and firmware upgrades. In the advanced settings, it is very rich, and provides automatic keystone correction, digital zoom, brightness adjustment and other parameters, users can easily adjust their own viewing effects here.
Cool Music does not look at the Q7 standard version without a complete UI, but offers a variety of projection modes is still very practical, office or entertainment can play it very well, and supports IOS, windows and Android platforms, users Optional wired or wireless connection is available.
The system also has a built-in screen function, the entire process does not require the use of other APP software, generally in the mobile phone settings, select more connection methods, and then open the wireless display to scan the connection.
After completing the connection with the screen, the content displayed on the mobile phone will be automatically synchronized to the projection. It is really cool to watch the video game, and the data in the mobile phone can be projected on the large screen at work, which is very convenient.
When inserting USB and other external storage devices, the system has classified and classified the U disk files. Users can choose according to video, music and photos. This design greatly saves the time spent searching for files. ,Improve work efficiency. The author took photos as an example. After it was opened, all the photo thumbnails were clear at a glance, but the 4K resolution photos for high-definition quality could not be displayed, which was a bit difficult for it.
Cool music as Q7 Standard Edition using TV boxes, mobile phones and computer hardware like to use, it is also very powerful. When I interconnected the Q7 with the Xiaomi box, I discovered that the two products are perfectly matched and look very similar to each other. Like a pair of twin brothers, they have different tasks. The Xiaomi box is responsible for the output of video resources. Cool Music regards Q7 as responsible for projecting video.
Cool music as the Q7 Standard Edition has a wealth of video resources instantly, all kinds of massive blockbusters have everything, the author is currently chasing drama "Ode to joy", this can also be under the big screen brings fun. You also don't say that the feeling is really different, even if it is more than 100 inches, the quality is still clear through manual focusing, but the edges are slightly blurred.
In the foregoing, the mobile phone's wireless screen function was introduced, and the content of the mobile phone can be projected onto the screen. In addition, the user can also connect with CoolVideo Q7 Standard Edition through the data cable, and can also perform the same screen. In the absence of television boxes, computers and other peripherals, the mobile phone has become the best partner.
Quality:
To evaluate whether a projection is good or not, besides having a solid workmanship, it is more important to have enough brightness to present the display content, and Q7 as an entry-level palm projection also has this point. Cool LeQ Q7 brightness as 130 ANSI lumens or more, thanks to the use of 3A high-current package LED light source design and 0.3 "DMDRGB-LED display technology, standard resolution 854 * 480 support 1080p video decoding playback. Compared to other similar The power of the 1-1.5A light source in the handheld projector is doubled. What kind of effect does the imaging have? After that, I will experience it with me.
Through the comparison of the above groups of real shot proofs and original drawings, it is found that the colors are true and the overall picture is slightly bluish. In terms of sharpness, it becomes blurry at larger sizes, so there are discounts in details. However, if the size is between 50-20, there will be a significant improvement. For a handheld projection product, this performance is very good. These excellent performances benefit from the excellent configuration of the Q7, which not only has a high brightness of 130 ANSI lumens, but also employs up to 27 quality rendering enhancements and a new generation of exclusive patented "LED transient modulation" and "dynamic gamma correction". Technology allows Q7 with such a small size to have excellent picture performance. Then look at the projection performance under the light?
In the state of turning on the lights, the contents of the photos and the reproduction of the colors are very real. Light imaging is a major drawback for projection products. In the high-end projection products between 3000-5000 yuan, because the brightness is mostly above 700-1000 ANSI lumens, it will be a good improvement, but how many will still have Affected. But for the thousand or so cool music as Q7, this performance is not easy.
to sum up:
Cool music Q7 compact, is a handheld micro projection product, support IOS, windows and Android multi-platform use, although there is no built-in UI interface, but the utility is still strong. Relative to the same price, the same volume of other competing products, Q7, regardless of appearance, configuration or all aspects of winning the competition. It not only has a high brightness of 130 ANSI lumens, but also employs up to 27 image quality rendering enhancement technologies and cool music as a whole new generation of exclusive patented "LED transient modulation" "dynamic gamma correction" technology, imaging is very good. Even if it is used for office, entertainment, or video, it can be played with handyness. Even during the leisure time of parking, you can watch a fun movie with your loved one and experience the fun brought by the big screen.
