I remember that in the previous years, the unit bought a Sony projector, which was expensive, and it was large and heavy, had complicated controls, and the fan also emitted a lot of noise during operation. It was not friendly at all. However, with the development of projection technology, there is a miniature projector with a smaller body on the market. Compared with ordinary projection, the biggest advantage lies in a more portable body design, and the price is more affordable than ordinary projection. , so it has been welcomed by many ordinary users. Cool LeTV as a long-term focus on the field of projection display company, has launched a miniature projection are popular, especially in 2017, after the launch of Cool Le Q7 ** months, once again launched its upgraded version of Q7S, with 170 ANSI lumens brightness, autofocus, 32GB body storage, touch panel features, HDMI input, all-glass lens and many other useful features, then this micro-projection how exactly?

Packaging, simple and fresh, the overall white as the bottom, the middle of the Q, represents the series model of the product.


Uncover the lid with a thin sponge to protect it from damage.


Each accessory has a separate box, and at this point it is still very hard. Separated into categories, it can fully protect the parts from damage due to bumps in transit.


Cool music Q7S as a whole is white, using a high-strength material, poly **, the surface of the piano paint process, polished by a number of processes, as the same crystal, grip will feel very smooth, moist and jade, the design is very simple , only positive LOGO as cool music. However, the cool music as the top of the Q7S also touch the special panel for notebooks, only need to move the finger on the panel, you can manipulate like a mouse, very convenient.


On the back, there are cooling holes, brackets, and standard ** tripod screw holes. Each corner has a round bulge, which is more conducive to heat dissipation and non-slip when laid flat.


Cool music as Q7S interface is still very rich, from left to right distribution of power, HDMI, infrared remote control, USB, 3.5mm headphone jack and so on. USB port can be connected to various U disk, hard disk, used to play local high-definition video, you can also connect a keyboard, mouse, used for some light work. The HDMI port can be connected to other input devices, such as notebooks, game consoles, etc., to serve as a large-screen display device.


Buttons are distributed on the right side of the fuselage, which are the power button, Focus+, and Focus-keys respectively. Although the Cool LeQi Q7S supports autofocus, there are times when the bracket moves slightly, or you need to manually fine-tune it, so that the focus is more accurate.


On the lens, Cool LeQi Q7S uses five full-glass precision aspheric high-definition lenses, its high refractive index, can present a more excellent clear picture, reduce the phenomenon of running out of focus, and the hardness of the glass is higher, can effectively prevent the lens from being scratched . Light source, the use of 3A high-current LED green light source, light source life of up to 30,000 hours. Cool Music regards the Q7S as having a brightness of 170 ANSI lumens, which is considered to be high brightness in micro projections.


Cool music as Q7S supports 0.9 short focal length machine, even a small space can project a big world. Support double trapezoidal correction, support horizontal ± 30 ° manual correction, vertical ± 40 ° automatic correction, which means that the placement is not centered but also can project a square screen. Cool music Q7S also uses OFFSET off-axis technology, so that even if the Q7S is placed on a horizontal desktop, it can be corrected with a small angle on the desktop support, thus presenting a complete picture.


Cool Q7S brightness as 170ANSI lumens, in the daytime indoors, what kind of performance will it? For this reason, I chose a sunny, semi-permeable curtain room to test how cool Le Q7S brightness performance.


I use a camera ** tripod, cool music as Q7S can be installed smoothly. After the cool music Q7S, press the power button to turn on, cool music as the Q7S will automatically focus after start, and the focus speed is still very fast, generally flash 2-3 times to clear focus. From the time you can see, at 4 o'clock in the afternoon, it is during the strongest day of the day when the cool music sees the Q7S display effect as shown in the figure, it is still very clear, of course, the camera's tolerance is compared with the human eye, There is still a big gap. The human eye feels high brightness and is clear enough. The camera may not be able to shoot it.


As for the contrast between the daytime and nighttime effects, you can look at the above picture. You must know that the time of day is 4 o'clock in the afternoon. It is the time when the sun is strongest. Although there are curtains, the curtains are semi-permeable, and the shading effect is not Too good, cool music as Q7S can have such a projection effect has been very tough.



Cool music as Q7S the actual resolution is 854 * 480, but support 1080P resolution, the actual projection effect is also very good, the specific can be seen in the above two maps, the model's hair is still clearly visible.


Cool music as Q7S is equipped with a large screen OS based on Android 4.4 custom projection OS cool OS, the interface is very simple, large icons more conducive to remote control remote operation, the first screen interface for online video, file browser, wireless with screen, all applications and Settings, the secondary screen is App Store, OTA, HDMI, User Manual and For AirPlay. On the left side of both interfaces are cool music ads.


Cool music as the Q7S uses a 4-core smart processor, accompanied by 1G+32G RAM/ROM, support for dual-band WIFI, network transmission speed faster and smoother, H.265 intelligent decoding, support for full-format decoding playback. In terms of content, Cool Music regards Q7S as one of the seven national licensed licensees, such as Galaxy, GITV, iQiyi, and other content providers. Online video content is very rich.


Of course, other video applications can also be installed through online stores. For example, it is now possible to broadcast a live broadcast so that you can install a betta to watch live broadcasts.


The recent glory of the Champions League of the Kings' Glory has been smashed. With the Q7S, Cool Music can shoot a 51-inch wide screen at a distance of one meter to watch the fierce battle between the teams.


In addition to online video, USB flash drives can also be used to play local videos.
