[The 239th survey] portable business entertainment tool without screen entertainment - Z4

First of all, thanks to easy fast provides such a good opportunity, but also very grateful to the other pole meters to launch such a good product fit my needs - Z4 Jazz color

As a code farmer who started playing video games in 1989 , now I personally basically face screens every day that are mostly small screens such as monitors, tablets, mobile phones, and notebooks. They are only used when playing games. To TV, that is to say if it is just a home projector that can replace the ordinary TV function, it can't satisfy all kinds of usage scenarios for me. After all, TV has gradually lost its dominance in the screen confrontation and it is being used by various small players. Screen seizes the time of use

But ordinary home projectors that can bring larger display areas and visual effects simply because of the limitations of their display effects and environmental influences, in my opinion, performance is not as good as that of large-screen televisions. Since last year, microfinance has gradually opened up a part of the market, and this one of them should be regarded as an absolute first-line manufacturer (at least as far as I personally understand, it is no problem to say that it is the leading manufacturer in the front line). It is also the Z4 series of portable micro-projection (the series also includes Air and small files), and it is intelligent micro-projection, which is different from ordinary projectors and can be used completely independently without relying on external video sources.

Now I would like to play with a few articles. There are traditional assessments, brain holes and presentations. There will be some conclusions in the end. (The picture can be opened in a new window, and the details will be clearer.)

The packaging color matching matte black with champagne gold looks stable and luxurious, giving a very high specification feeling. Following the packaging of the Z4 micro-projection series is also a clear feature - three-stage packaging, personally open is also a very novel experience. In fact, only the left and right sides of the three sections are only connected. In the middle, they are protected by a thin film on the outer layer. I personally recommend putting a brief description outside these packages. Use a picture to indicate this three-stage opening, or simply print it on the back of the package. Because if you are anxious to open the person is very likely to use one hand holding the split film packaging, it will probably lead to accessories and even the local slip, to tell the truth, I almost slippery ... ...

There are some product features on the side of the box, such as 180 -inch super screenless TV, wireless protocol support such as Miracast , DLNA , Airplay , full HD support (output is 720P, but supports full HD input), using Texas Instruments DLP technology , LED 's more than 20'000 hours of life, but also supports 3D , using the active shutter 3d , just take a look with DLP-Client 's active shutter glasses can be used. At the same time, we can also see audio and video partners. Of course, Mango TV is more important because they have Internet video licenses.

The family portrait is as follows:

Ontology        ×1 : The official data is 113.5×214×23.9mm . If you pick up three things, it will be like a lunch box ...

Remote control ×1 : approximately 150×34×9mm

Power supply × 1 : The cable length is about 1.7m , which is convenient for long distance power outlet under any circumstances

HDMI ×1 : about 1m long, in fact due to the good support of wireless protocols, in most cases there is no use ...

miniUSB cable ×1 : very short, to charge the remote control, and HDMI cable, have a logo

Warranty     ×1

Manual × 1

Value of 360 Mango VIP Card ×1 : Content Provider, also a Video License Party, This is a VIP for the whole year

Ultra-concise instructions, and the same as the warranty, the material is very good, black with a similar gold foil effect of the dark gold text, so that the overall package of high-quality feeling of refinement continues, to convey even if this small details, but also elaborate. The value of 360RMB mango VIP card, well, after all, Guanghan , ah, no, radio and television request no license does not work, and Mango's achievements in variety shows for all to see, but also provides a wealth of video content, even if not VIP itself has enough content Can see

Wires have their own logo , the interface is neat, and the material feels good. The power supply adopts a two-stage structure and supports 100-240V at the same time. With wide voltage support and replaceable plugs, it is clear that the international market is at the forefront , and the surface3 at hand is also such a design. The output is 19.5V and 2.3A , it seems that the power is still relatively large, has already caught up with the low-voltage version of the notebook, of course, if compared to TV, ordinary home projector is much smaller

The remote control is champagne gold and has a rechargeable lithium battery. Exquisite and compact, even if it is a metal scrub, feel very comfortable, good feedback button, press a clear feedback. The distribution of buttons is relatively scattered, and even if you do not watch or blindly press at night, you may not accidentally press it. But one thing that makes me personally feel uncomfortable is the home button and the return button. Most people are right-handed. In these two buttons, the return button is generally used more frequently, but it is placed on the right side. At the time, the thumb must have a clear pull-back action. To be honest, it's a bit tired. Of course, changing to the left hand is actually quite comfortable. This is not sure what the concept of design is. It is Bluetooth 4 itself, which has a wider scope of application. At the same time, the standby time is still very good. At least 10 days of playing have not been charged.

In addition to the traditional buttons, this remote has some special features in it. The following is the first power supply voice button, the button on the left side while supporting edge is the microphone, that Z4 Jazz color support voice operations, while itself if the system supports it, the future is not it also have be ok the function? Of course, it is not now. At the bottom there are fn function toggle buttons, miniUSB charging port and Reset button. Above is a laser transmitter to demonstrate PPT is very good. By the way, the power supply has blue, green, and red color hints, corresponding to the connection + function prompts, key response + power enough, low battery power, ringing prompt moderate brightness, not dazzling at night, this point for a projection Remote controller is necessary, after all, most of the projector will make the environment dark, a brand of remote control that light pollution and the PS4 just can not turn off the handle lights an effect. At the same time, this remote control also has a gravity sensor and a flying squirrel pattern.

Finally came the body, the same champagne gold metal matte shell, but looks deeper than the remote control, 3D according to the official website is said to be 214 × 113.5 × 23.9mm , the front is only the slide switch and the main cooling outlet, slide at the same time With the lens dust cover and power switch function, so my different colleagues often have someone to get it to play and close it ...

On the right is the focus key and key, it should be the air inlet, focus key positioning is very accurate, feel fine when fine-tuning the focal length. The left side is empty, the left rear is the indicator, there are red and green colors, the meaning is clear

The back is very important: power connector, USB2.0 , USB3.0 , HDMI , headphones, mobile power switch and stereo. The two USB ports are of great significance. If only a single USB is used, many mobile hard disks cannot be used. The loudest sound volume is still very large, and at the same time the effect is good. It is worth noting that the Harman Kardon's sound is said to be officially spoken. At the maximum volume, there is still no broken sound. At the same time, the bass effect is done well.

The mobile power switch is very interesting, because the Z4 Jue directly built a 13600 mAh lithium battery, in addition to their own use, but also directly as a mobile power to charge other devices. Yes, with it even charging Podu province, when charging the voltage is basically 4.80-4.85V , USB3.0 mouth current is between 0.60-0.65 , while USB2.0 mouth current range is about 0.05 more

In terms of weight, the unit weighs 667g . If it is powered, it is 825g . If you add a remote controller, that's 882g . Actually, when I use it everyday, I only bring the body, and occasionally it will bring power. With the remote controller, the main unit can be used for almost three hours. (In the theater mode, there is still 10% left in about two and a half hours. It is estimated that the energy-saving mode should be able to easily reach three and a half hours.) A whole movie is enough, and it's already longer than my computer work. The remote control, you can use the phone instead of APP, APP done very well, enough to replace the remote control, although without the remote control so fast, after all, I can blind by remote control, according to APP blind unrealistic

The following boot (these are the night light only, the effect of hitting the wall), the first boot will have a picture + voice guide the user to boot, connect the Bluetooth remote control and other steps, simple and clear

The black box on the wall is a magic card. You can see the contrast below. The projection distance is about 2 meters, about 90 inches, and the default cinema is used. In the model, due to the influence of the photo equipment, the effect actually seen by the naked eye is much stronger than in the photo, especially in brightness and saturation. It can also be seen from the figure that the projection pixel is square, better than the diamond display edge

The system is based on GMUI developed by Mimi itself based on Android4.4.2 . The license plate is made of mango. The whole is similar to various smart boxes and smart TVs in the market, and anyone can easily get started. The included Mango TV VIP guarantees rich video content. The music channel is cooperating with Baidu music, but as a dead house, a lot of people often listen to ACG music or not, it's a pity, but the overall interaction is still very good, plus the sound effect of Harman Kardon itself, as a Mobile portable audio is also good. The system also has a game center and an application center. Of course, the General Administration of the People's Republic of China requires rigid requirements, and many things cannot be seen. Of course, there is a high degree of savvy, and there are still methods to be installed. The overall system feels very realistic and can meet the needs of the general living room. The system also has a desktop for business use. The default interface is based on office needs. At the same time, the hotspots are easy to demonstrate. (These diagrams are screen shots directly by the mobile phone assistant of Mimi and will be directly marked with a watermark and sent to the mobile phone. Very convenient)

Then set the page, after all, is not a simple box or television, in addition to traditional, but still have a lot of features in it. Divided into six modules in general, the network supports wired and wireless, while wireless supports 2.4G and 5G at the same time. You can set up an agent and do what you understand. You can set hotspots. If you want to use the environment without a network, you can open a hot spot in advance. At the same time, if you have a wired connection, it's OK to open a hotspot, but you're too talented. The wireless protocol supports both Miracast , AirPlay, and DNLA . The convenience brought by multiple protocols is in line with the ease with which micro-projections can be used in multiple scenarios. Bluetooth can be easily connected to a variety of devices, plus the use of USB , no remote control just find a mouse is enough, Bluetooth speakers, keyboard, handle what is also very easy to connect

There are many things in the projection settings to meet various needs, LED has four default + custom a total of five modes, the default is a cinema mode, the most balanced, the effect is relatively appropriate, is a universal mode. In both the power saving and energy saving modes, the latter has lower brightness. Another is the brighter mode than the cinema mode. In the customization, you can customize the brightness, and you can also configure the red, green, and blue, or you can let the machine automatically adjust the light, which is the ambient light. There are also four projection methods, which are suitable for different usage habits. However, I think that there are more right-handed shots and positive-fit rear-projection shots. After all, portable micro-casting must be fixed with the back-loading, and the total scope of use will be much smaller. The trapezoidal correction can only be vertical plus or minus 40 degrees, and the level is generally not what the micro-projection should do. Infinite zoom actually has the same overall projected size, but it looks like the viewing area has become smaller. The principle of digital zoom should be used, I guess. At the same time you can customize the wind speed, basically, the default is about 36 decibels, open to the limit is about 50 , compared to ordinary projection is still very quiet. There are other common settings android system and simple information, but the temperature should be the temperature of the cpu , generally still look very high

The default also provides a resource manager, Mango Internet TV, WPS and other popular APPs , as well as a one-click clear function. The system can be set to put some commonly used functions in the following shortcut bar, this design is very convenient

Press the menu button on the desktop will jump to the APP area, you can delete and other common operations, equivalent to the effect of long press the OK button on the APP icon

The long press the menu button can call out the bottom shortcut menu, common operation is quite a lot, but it is recommended to add a key to clear, although most of the time 1G memory is enough, but after all, a lot of APP is really not written, performance is too Not pay attention

Pressing the voice key will call Xunfei TV language points. You can directly interact with the voice by holding down the voice key. For example, if you want to search for a movie and listen to music, you can also directly open your own application, and this is not just for the desktop. Use, can press at any time, it is still very convenient to use

Speaking of voice, I have to talk about this remote control. I also said that this is not just an ordinary remote control. In addition to the laser pointer and voice function already demonstrated, it can be thrown into the flying mouse mode. With the air mouse, there is a slight delay, but the impact is not great. This mode is very useful when you encounter the inconvenience of the arrow keys or the application for the mobile phone. However, there are certain drawbacks, that is, sometimes throwing the remote control to the bed will trigger ...

At the same time there is gravity sensing function, you can simulate the tilt of the phone to play the corresponding game, it should be said that this game can play a lot more, I just find two gravity sensors, are ok , this is outside the rain Photographed on a cloudy day, you can clearly see the gravitational induction of the picture below, I was running to the wall, but also the end of the front ...

It can be said that this remote control does bring a lot of convenience to the entire entertainment and business operations. However, in light of the principle of carrying light and light on the outside, I also said that the power supply and the remote control can be used without the former. Because it has a 13600mAh battery, three hours of support has basically met the need for out use. The reason that the remote control can be left alone is that it provides a very nice non-screen assistant APP . In addition to direct video, audio and loading software, the best feature is to completely replace the excellent remote control. There are not only the traditional remote control mode, but also the air mouse and voice support. The best is that there are many quick settings. The realization of it is also used to open the projector to open the APP . Some quick settings are too convenient.

At the same time, this function of screenshots should be singled out and praised once, and screenshots can be taken at any time! Anytime screenshots! Anytime screenshots! Important things must be said three times, this is too cool, especially when the external game consoles play, when it comes to cool, cut a picture, you can directly share, do not have to rush like the original to unlock the phone, re-license Share, too convenient, is the size of the watermark can be set, ah, sometimes is blocked to the key ...

Direct mobile input also makes the operation a lot easier. After all, the remote control input has long been enough to play the game console. The other is the same screen function, you can synchronize the projector display directly to the phone, my child is very interested in this function, just like using a mobile phone, it is very convenient. So this is what I said, if you really go out, really can reduce the 60g weight of the remote control, although it did not reduce the number of it ...

Everyday use, common applications are ok , no caton, video playback is also very easy, 1080 and 2k are very smooth, given the ultimate projection effect of 720P , 4k what I did not try, it does not make sense

Then tried some simulators, basically to the era of PS is still ok , psp has been stuck, and actually ran under the points, it should be said is similar to thousands of mobile phones, daily use is completely without any problems, large games will be very difficult

External articles:

The above is all independently used. After all, Z4 is a smart micro projector that can be used without relying on any other external video sources. But it is still a projector, but still use an external video source

The first is a variety of wireless screen, first to say the conclusion, one word: cool

Audio and video projection and picture projection are not common, and are now supported by any smart TV and TV box. The Z4 Grand Color is no exception. What makes me most satisfied is that Z4 can achieve a variety of platform wireless projection

Android , the next music player screen app on the line, any operation is very real-time, visually measured up to nearly 100 ms delay, very comfortable

iOS is better, direct AirPlay screencast , is more convenient than Android , and the delay is even smaller

PC , regardless of win7 or win10 , the next meter with the same screen assistant can also be resolved, but the delay is basically more than a second, the following furnace can see that delay slag, playing a higher demanding game is not alright, but see The book, debugging code is very happy, my old display can also be laid off, this is bigger, for us yard farmers, the larger it means better for the cervical spine, after all, occupational disease ah ...

Now most of the time hdmi is useless, but consoles and other peripherals still cannot hide wired links. Fortunately, the Grandfather Z4 supports a very wide range of input resolutions. Wii 's 480P has been to me. The Remix Mini's default 1080P is perfectly supported. The 720P can also be used with a computer that is very comfortable to use. In the end, I'll put some photos of the contrast map, and now this one will serve on the small map. After all, there are too many photos. After playing games, I made a few hundred. Of course, I found that most of them were empty. It's not a human thing to play games while taking pictures ...

By the way, if you don't have a hdmi video source, you will see a familiar picture. If you feel very kind and feel like it was on Tuesday, then congratulations, you are old ...

Scene articles:

The above is a standard evaluation of a smart projector, whether it is used independently or externally, is very convenient, and its own weight and battery capacity ensure that it can be used in various scenarios. There is no problem at home as an ordinary smart projection, and taking out a business presentation also accounts for anytime, anywhere, and the business value is very large. What else is it? Of course, it is the scene that is projected everywhere. For example, if you come to a wall painting or a line drawing, even if it's based on my completely zero painting, you just need to find a picture. Ah, it's too simple, than the mysterious garden. It's also simple N times. And the most critical, the effect is really very deaf

At first, he was so timid, he described a slap-heavy Tauren on the wall, the left side is a map, the lower right corner is the size of a scooter, Lok'tar Ogar ! (Which takes 25 minutes)

After the courage, a direct 15 -inch wire rope + Hakata logo, is really super simple, is to put the projector frame, select the map, direct description ( 20 +15 minutes). The next step is to look at how to paint the walls, plan to build a bigger project, draw the entire 1-1 mario generation level, it should be a great sense of final achievement, and this is definitely the world's unique version

Then put the Z4 Grand Color behind the head and tilt it, plus my mobile notebook table can be tilted, which is very suitable for tracing paper. It is also super convenient (about 18 minutes, it takes more time to black). I am willing to use all the aspects to change the life of Gintama.

When drawing a note is that, 10 million, must use energy-saving mode or custom to adjust the brightness to very low, or too dazzling when the close-up projection, basically within 24 inches must use energy or even lower Brightness, solar day's balcony, 19 -inch energy-saving mode is such an effect. In the outdoor trial, the shadow of the cinema mode is basically the same effect, even if the sun, I can not see the phone .

From this effect, it can be seen that if you want to design T or similar flat things, you can use Z4 full-color projection to see the effect in advance, and then expand the point, it is suitable for the decoration of the projection of a roughly flat surface effect, which is also only intelligent Micro-capture Caixing, after all, holding an ordinary projection around the projection is not realistic, but with Z4 can be completed with one handful of color

It is estimated that if you want to buy a film, you should also be able to directly perform holographic projection at home. You can watch miku dancing at home. I haven’t bought it yet. Look at the renderings. It should be pretty good. It is more suitable for Halloween use. Interested ones can look up the holographic projection on the Internet. membrane

Of course, if the Z4 Grand Color requires a variety of positioning devices such as gyroscopes, there is more to play, such as direct navigation on the ground or on the wall. For example, you can directly cast a constellation on the ceiling. When you go out, you have to hit it in a tent. Then you can go out and look directly at the shadow of the constellation that is on the tent. It is also a very interesting thing to look for the real constellation. However, there are also workarounds. I am looking for someone to help me set a small shelf and bind my mobile phone to the Z4 Grand Color. Just like the picture below, plainly speaking, it is fixed in accordance with the T- shape, and the mobile phone itself is in various positions. , and then use the APP itself can be the same screen, so that you can meet my requirements, although it looks very strange, but the development of the brain hole is still very interesting ...

Another thing I think of is that Microsoft's Hololens is a glasses-type AR , in fact, can also be made into a projection AR ah, put it plainly from the projection to the glasses instead of projection to the real object, may not be flat or the effect will be much worse, The plane should be good. And one thing is that since the Z4 Orange supports 3D , that is, you can cast a 3D effect, the effect of that decoration will be more realistic. After thinking about the opening of the brain hole, I also thought about it. In fact, there is a simple realization plan. It is to replace the mobile phone that I want to bind with a camera in the middle, on the edge of the line ...

Well, open the hole, or to pull back, projectors generally have a problem is that after prolonged projection out of focus, the measured Z4 effect is much better than expected, basically did not see obvious defocus, should be attributed The program in Texas Instruments is excellent. Another is the temperature and noise, not to mention, look directly at the map, the temperature control is very good, much lower than the appearance of my mobile phone for fever. The noise was measured with a mobile phone. The default wind speed was basically 35dB+- , very quiet, and the manual adjustment to the maximum wind speed was basically at 50dB- , which was also not as quiet as the purifier that was born for fever. Good noise control is really important for people watching movies. No one wants to see what the engine of the off-road vehicle is next to.

The rest I want to focus on showing the screenshots and the actual results, are the theater mode, pull the curtain, the same, the photo effect is far less direct than the human eye. We should say that at home, effect is enough. The following pictures, in addition to the reduction and the puzzle, have not been optimized. Basically darker situations are very good, and the daytime effects are generally good. Looking at colors directly through the eyes feels cold

Then in the extreme darkness, the effect was surprisingly good, but the cold feeling was not there.

And I also made a big death directly against the sun and the lights are bright enough, I played in the highlight mode, well, the effect is OK, 250 lumens is not high, but in the moderate projection area there is still a good effect . By the way, you can also take a look at the square pixels, the edges will be sharper than the diamonds, and the discoloration will be better.

It can be said that after only 10 days, I decided that I really needed a smart micro-projection such as a Z4 Grand Prix. It had enough power for 3 hours, relatively light weight, and excellent results. Only meet these conditions in a variety of scenarios to better use

If you just want to have a particularly good display and use it at home more than 90% of the time, especially if you are sure to use it when there is plenty of sunshine (such as when using xb series kinect ), then Z4 may not be your Yes, but if you have a lot of usage scenarios like me, and you are pursuing anytime, anywhere usage and brain-drilling gameplay, Z4 should be a very suitable product.

By the way, I would like to ask if there is a matching carrying bag. Or interior bag is also OK, after all, unlike other home projectors, this Z4 Jue will be more out, it should be said that if there is a package, then the overall convenience will be further strengthened

Another is, if, I mean, if there is a projection of win10 or ubuntu, it would be more suitable for use by our coders, and I don’t know if it’s feasible.
