Hand-held projection does not fly? Cool music as Q7 extreme brightness test



There are many styles and brands in the hand-held projection market, which has led to the mixed hand-held projection market. The inferior products are everywhere, and the market is in desperate need of a product as a benchmark. However, due to the limitations of compact size, brightness performance is often not good, basically only a few dozen lumens, resulting in the actual effect of such products is not ideal. Recently, Cool LeTV has just released a new hand-held projector - Q7 or will become a clear flow of this market, this handheld projection and other products What is the difference? In the next evaluation process, the editors will reveal to you one by one.


Cool Music sees the Q7's brightness of 130 ANSI lumens, which is much higher than dozens of lumens of other mainstream handheld projectors. The reason is that Cool LeQi Q7 realizes a high current encapsulated Led Light source design of 3A, and the light source energy is 2-3 times higher than similar models. Compared to the previous generation Q6, the brightness increase is also very large. This kind of light source design is how much the brightness is improved. We will tell you through actual tests later.
Cool music as Q7 equipped with a 0.3 DMDRGB-LED display technology, the standard resolution of 854 × 480, supports 1080p video decoding playback, bring more detailed projection effect. The Cool Music Q7 has a short throw ratio of 0.9. It only takes 1.9 meters to project 100 inches. At the same time, Cool Music considers the Q7's "inside" to be equipped with a 5000mAh battery.
Small and compact, it's easy to carry. The Q7's shell is made of high-strength polycarbonate. After being polished, it looks like a crystal. Unlike Cool Qon Q series products, Cool LeQ Q7 looks more simple and stylish atmosphere. It is worth mentioning that its compact size, only a 270cc/280g fuselage can easily hold a palm, put it in the pocket is not significantly bulky.


Q7 thickness is only one dollar coin size



Q7 and bracket are more suitable

Next to tell you that the difference between the cool music Q7 is that it is not equipped with a remote control. Yes, you did not misunderstand, Cool Music Q7 does not have a remote control, all operations must be done on the top touch-control panel. Something doesn't apply when you just touch it, but it's more convenient to use it in your hands.

Cool music as the Q7's right side of the fuselage to set 3 physical buttons, respectively, is the key to open, focusing F + key, focus F-key, the fuselage has a cooling hole on the front and bottom design, the entire cooling system will automatically according to the internal temperature of the machine Adjust the wind speed. In the actual test process, cool music as the Q7's cooling effect is still good, but also in the processing of noise has also worked hard, noise is much lower than similar products.

Interface close-up

Cool music as the back of the Q7 set up 4 interfaces, including DC power interface, a USB2.0 interface, a high-definition HDMI interface and a 3.5mm headphone jack, although the interface is not as complete as the traditional projector, but the current projector In terms of use, Cool Music regards Q7 as having all the functions of the interface, and there is no problem in daily use.
Functional System Externally Expanding Performance The Cool Lexus Q7 has also undergone major surgery on the system, giving up the Android Android smart system, which also means that all Q7 resources and content can only come from external devices (HDMI, USB, wireless/wired Same screen). This approach has both advantages and disadvantages. The advantage is that the system itself is more concise and stable; of course, the disadvantage is that users who are used to Android will not adapt.


Cool music as Q7 system interface



After booting, it is not difficult to find, Cool LeQi Q7's system interface is very clean and simple, the interface has "EZCAST-IOS wireless screen" "EZmirror-Android wireless screen" "EZWire-USB cable with the screen" "HDMI-in" " Meadia-U disk entrance "Setting-Settings" six entrances. The settings also include some detail settings, including brightness, contrast, and color fine-tuning, which are not available in typical hand-held projections.


The same screen operation mobile phone interface and the same screen effect

Android screen method

Although not equipped with an intelligent system, but the cool music as Q7's same screen function is quite good. In addition to being equipped with a common PC on the projector and miracast/Airplay/EZCAST wireless screen, it is also possible to connect a mobile phone to a screen via USB. This function still gives people a feeling of light up, and no matter what the way the screen is, the whole operation is relatively simple and easy to use.
Limit testing is naturally afraid of fire gold people generally believe that the projector is only used in the dark room to get the desired effect. Whether or not the projector can be used in the daytime or in the lighting environment has become a focus for consumers. Although the brightness of hand-held projectors is much lower than the brightness of traditional projectors, this limit test of different sizes in different environments must be treated equally. After all, real gold is not afraid of fire, so that it can give consumers a projection. Machine real performance.


Test the environment of the conference room



(The left size is about 80 inches, right is about 100 inches)



The best effect of the conference room during the day is 30-40 inches (the right picture shows the left picture face length of 86 cm)

We first selected a conference room around 2 pm as a test environment. From the figure we can see that in the daytime environment, cool music Q7 in the projection of 80-inch screen is fairly clear, but after zooming to about 100 inches, the screen is basically difficult to see. In the same environment, we found that the best size of Q7 in the daytime environment is between 30 inches and 40 inches.


Turn on the conference room lights



Projection effects under the lights can be completely ignored



After reducing the size, the effect of turning on the lights is still good (the picture on the right shows the length of the left picture face 56cm)

Next we turn on all the lighting in the conference room and see how the Q7 will perform under the lights. After turning on the lights, we discovered that the picture was blurred. At this time, we invited our colleagues to hold the Q7 with cool music to gradually reduce the size, and found that when the size is reduced to about 20 inches, the screen effect is the best.


Or the effect of the full black mode is the best



Xiaobian forcibly photographed and compared the dimensions for everyone (right picture shows the left picture face length 140 cm)

Finally, we returned to the darkroom of the evaluation to see how Cool Music looks under the Q7 all-black environment. Through real shots, we can easily find that the effect is still the best in the all black environment. Both the brightness of the screen and the performance of the color are much better than those of the previous two environments. Of course, Cool Music regards the Q7 as a handy projector with a very small size. It can have such a picture performance in the daytime environment and the lighting environment. It can be seen that the performance of this projector is still good.
The real shot of the picture is clear and detailed. For an entertainment hand-held projector, the quality of the viewing effect is a concern for the user during the purchase process. Cool music as the Q7 is not equipped with a smart system, we connect through an external device to test the cool music as the Q7 on the performance of different styles of movie screen performance? Let's take a look at some of the following movie shots.












Through the above a few real shot map we can find, cool music as the Q7 as a hand-held projection, such a projection effect is quite satisfactory. Many details in the picture have been well preserved, the picture is clear, and the overall degree of reduction is high. Although there is still a certain gap between the details and colors compared to the conventional home projectors, in the field of handheld projectors, such picture effects are still worthy of recognition.
Color test reproduction and sharpness performance is good Color testing is a common test project for our evaluation projector, the main purpose is to examine the color reproduction capability of the projector, that is, projection, by comparing the color test sample and the real shot figure. The ability to accurately restore the true colors, there is no color cast, color brightness, saturation, warm and cold tone and so on. (Because of the equipment, there is a certain error in the real shot chart)

We can see through the above a few color contrast charts, cool music as Q7's color reproduction capability is still possible. The images presented are cool colors, and the color saturation is not as high as the original image. From the figure close-up comparison chart, we can see that many details in the picture are still well preserved, and the picture sharpness is excellent.


The left is the real sample of the test sample right

In the comparison of the four-color maps, it can be seen that the reduction of the yellow and green colors can be achieved without significant differences, but due to the problem of insufficient brightness, the red block is significantly darker than the original image. The blue block appeared purple, which is also a common problem of micro projectors. Overall, Cool Music regards the Q7 as relatively close to the original in color rendering.
The focus test is slightly out of focus. The focus test focuses on the focus of the projector. We examine the focus of the projector through a fixed PPT test file. For the pico projector, it is prone to poor heat dissipation due to its small size. , resulting in thermal defocus phenomenon. So how does QC's focusing effect look? Here we look at the test shots actually taken.

Judging from the actual PPT files we have taken, Cool Q7 can still focus on Q7. Most of the text, English, and numbers on the screen can be clearly projected. However, some parts of the picture may not be visible. Cool music as Q7 focus is still some problems, need to improve later.
The brightness of the hand-held projector

Finally conclude that two sentences:

Advantage:

1, small form factor, not burdensome to carry

2, measured brightness is good, high brightness in handheld projection

3, equipped with 5000mAh battery, good battery life

4, interactive function with the screen, strong expansion

Disadvantages:

1, not equipped with intelligent systems, their own resources are insufficient

2, does not carry the remote control, control operations need to adapt

Cool music as the Q7 in brightness compared to other similar products has made a great improvement, the measured brightness is also a hand-held projector in a very good performance model. At the same time, Cool Music regards the Q7 with a projection ratio of 0.9, and the larger screen requires only a smaller distance, and the same can be seen in a small space. In the presentation of the screen also reflects a very high degree of reduction.





Cool music as Q7

In general, Cool Music regards the Q7 as a well-performing micro projector that is carried around. Whether it is appearance or performance is a good choice. Although it does not have an intelligent system, it is not competitive in its own resources. But good external expansion has made it regain one resource in terms of resources. And the price of 1,699 yuan will not make consumers have too much burden. In summary, the Cool Music Q7 is a good handheld micro projector.
