I. Product Introduction
Lami is a brand that is mainly sold online. As a new force in the projector market, the development of the poles is quite rapid. This year's 618 sales in Jingdong have surpassed that of the oldest projectors. According to statistics, in recent years, the projection prices that consumers are paying attention to are more concentrated in the 5,000-yuan or less, and micro-casting is the main method. The ordinary people are eager to install, easy to use, and easy to use. A market pain point is expanding and does not pursue the most professional performance, but it can provide the most convenient and quick experience

Second, Z5 out of the box
The projection of the rice cooker itself is called “non-screen TVâ€. As a brand logo, it is easier for people to remember it. Compared with other professional projections, it is also a differentiated competition. The point is that the apparent use scenario of TV is definitely a family. Office.



Easy to open seals.

The shape of the Z5 is a short cube. Compared with the Z4 series flat shape, the Z5 is quite compact and has a smaller footprint and is easier to find.

The front of the Z5 is the projection lens and speaker section.

There are four physical keys and volume adjustment touch keys on the top. The combination of drawing and mirror design has a good visual effect.

The interface and power are concentrated behind and we can see that the Z5 provides us with two HDMI, one USB2.0, one USB3.0, a 3.5mm audio port, a LAN and a fiber interface, the type can meet all the daily home demand. The distance between them is relatively large, and there will be no case where B cannot be inserted when A is inserted. The interface grid grid is the outlet for heat dissipation.

The air inlet is at the bottom.

Accessories include a power adapter, remote control, and projection adapter.


From the adapter, it can be seen that it supports AC voltage in different regions of the world. The output power of 19V-6.32A is equivalent to 120W.

The remote control is small and powered by two AA batteries.


The Z5's included docking station is useful. It's not easy to find a highly suitable location for the projector at home. We only need a tripod with a standard screw after installing this transfer tray.

At the time of installation, we first screw off the pad screws on the bottom of the original Z5;

Then add spacers between the adapter plate and the projection and tighten the fixing screws. A certain height is set in the middle to make room for the air inlet.

However, look at the bottom of the adapter plate, I guess this is dedicated to their own projection of meters, square tripod quick loading plate is not very suitable after loading up, but after tightening down is still very stable.

Third, the projection effect
After the installation is in place, we look at the specific effect. Under dark conditions, the color and brightness of the Z5 are satisfactory, and the brightness is even a bit too high, causing me to specialize in the settings to lower it a bit, but not during the day. Pull the curtain or turn on the lights, the brightness of the Z5 is certainly not enough, if you want to use during the day or need to pull the curtains that indoor environment is a little dark.

Or in order to ensure the brightness of the screen, we can reduce the distance between the projection and the wall / curtain, so that the screen will be more bright, after all, the smaller the area illuminated by the same light source, the greater the amount of light per unit area. But this will cause the screen to shrink, the advantages of projection will be gone, so it is still honest to turn off the curtains

Keystone correction is a standard feature of most recent generations of meters. It can correct trapezoidal images caused by projected light that is not perpendicular to the projection surface. It is mainly used in the following scenarios.

Z5 can be corrected up to 45° in up, down, left and right directions. If the home is not enough or there are obstacles blocking light, it is really useful to put the Z5 on the side and correct it.

However, the correction process is not a pure optical principle. Instead, the width of the picture is directly changed inside the machine. This results in a reduction in the resolution of the picture side and loss of definition. The following figure shows the Z5 projected from the right side and the corrected fullness. It can be seen that the brightness on the right side of the picture is higher than the left side. Because the width of the right side is originally small, the light is more concentrated. This is also one of the problems caused by the correction.

Then compare the details of the picture, the following is the left side of the corrected picture, it is easy to see that the corrected side of the picture quality will be worse, mainly due to reduced resolution.

The following is the right side of the screen. It can be seen that the trapezoidal correction has both advantages and disadvantages, but since I am full of correction levels when testing, it is an extreme situation, we generally do not need to tune so much in life, when I actually use the Z5 viewing, the picture The inequality of brightness and resolution on the left and right is basically invisible.

In terms of sharpness, the resolution of a pole meter is 1280*800. When watching a movie and TV series, it is equivalent to 720P. This resolution is projected on a 1.5m-2m wall, which ensures that the picture is relatively clear and the projected picture is again Although some of the larger ones do not affect the viewing, the jaggies of the picture are larger and become “not so clearâ€. Therefore, it is recommended that if you want to pursue a bigger picture, you still have to choose a higher-end machine. Suitable for use in a bedroom that is not as large as a wall.
The following is a partial enlarged view of the two groups, the first group is my own 1080P source, the second group of iQIYI's 720P source, I feel it is quite clear.




Just talking about serrations, it made me somewhat confused

Z5's pixel arrangement does not seem to be arranged side by side with rectangular pixels, but rather “arranged diagonallyâ€. Therefore, the more obvious sawtooth can be seen at the edges of the screen. The more straight lines are, the more obvious the lines are; No, because there is no straight line, so the impact is not great (but why is it so arranged?)

Fourth, functional experience
Z5 as a home projector, the main demand is to watch video, so you can enter the user interface to see the navigation bar is directly classified according to the type of video, movies, TV series, variety, etc.; modular interface with the TV box, easy to use the remote control . One of the video resources comes from major video sites and has been integrated, such as "film" resources are both iQiyi, but also mango TV.

Although these data are all integrated by Mango TV, most of the resources come from iQiyi, whether it is movies or TV series. In addition, most movies are required to purchase members to watch. After all, the best way to manage a membership system is to love iQiyi.


However, TV shows can be watched for free. This is China’s national conditions. Of course, TV dramas will be charged as abroad as they are in a few years.


As for the members of the iQIYI, the number of cards for the year is 30. If you love watching the drama and you love watching HD, I feel it is acceptable.

3D content is not much, mostly old movies, but also need to buy members.


This time we need to find a film for ourselves. With the bt that has not been subjected to poisonous hands, as long as it is about 3D format, then we can engage in a generic 3D glasses, of course, we can also buy a very Mi brand of their own set.

Variety Well, the strength of Hunan Satellite TV, so the resources of Mango TV have finally appeared here, but I feel that the current variety shows and reality shows are really meaningless. When I'm free, I just watch TV. If I miss it, I won’t go. Watch Replay on the Internet (I’m very embarrassed by the new song and fans don’t spray me)


Their own resources, in addition to insert U disk, mobile hard disk is also possible, it seems that there is no problem with the expansion of the capacity limit.

Mobile hard disk looks like it can only be placed on the top and there is a risk of falling.

With respect to video format support, the Z5 can basically play all common formats. I tried the ts-format Blu-ray large file to play smoothly.

In addition can also be Z5 into HDMI input connected to the computer, so it is no different from the traditional projection, and sometimes too lazy to copy out the computer's film, directly to the Z5 can even look at the computer (HDMI line to bring their own)

It should be noted that the projection lens is the same as the camera. Every time you move the camera, the focal plane will move, which will cause the screen to become blurred. It is best to adjust the focal length after moving.

Focusing switch at the bottom of the remote control, dial to the "FOCUS" side and then use the volume plus or minus keys to adjust, the entire process does not open the Z5 system's internal settings menu, it is convenient.

The Z5 is an Android system like a TV box, so it is possible to install APPs and provide some games, but it is estimated that no one will play. I only use the “no screen assistant†in the APP. This is a remote control for the mobile phone. And the same screen display application.

There is a certain delay with the screen, and it doesn't matter if you watch videos, but if you want to use a mobile phone as a handle to play gravity sensing games, it's not a good idea.

In addition to the projection, the Z5 can be used as a speaker alone. Pressing the top music key in the off state directly turns on the wireless network radio to play music at random. The rear row of touch keys is used to adjust the volume, the advantage is good-looking, the disadvantage is that it is easier to touch than physical keys.

Z5 can also use Bluetooth to play music on the phone, with Harman Kardon's help so the sound quality is pretty good, and the Bluetooth speaker below a thousand dollars is almost a standard. Z5's speaker function is very convenient to open, Bluetooth is automatically connected, so usually as a speaker to use no problem

Fifth, the advantages and disadvantages
Z5 is easy to install, easy to use, and less demanding on the venue. It can be used even when connected to WiFi. The resolution is good, but 1280*800 resolution cannot be used in large areas. The interface is rich in external mobile hard disks and computers; trapezoidal correction function is reduced. Using the site's environmental restrictions, you can also cast a normal screen obliquely, but it will lose a certain degree of clarity; online video resources are rich but many need to open a membership, and the members of several video sites have opened a small one hundred Block, only if I love Qiyi, then 30 yuan is still acceptable. In addition Z5 can be used alone as a Bluetooth speaker, sound quality and easy operation. The price I think is still reasonable, new products will be reduced prices after a period of time, it is estimated that when the double 11 will be below 2899, this price to buy I feel is quite worth, after all, is equivalent to sending a Bluetooth speaker
Disadvantages: too much advertising, boot animation and hibernating screensavers are all advertisements. Others have already bought your product and have to keep watching advertisements. It seems that the settings cannot be switched off.


There is also a problem of the lens falling to the gray, the lens looks like the seal is not doing well, the cooling fan will pull the wind from here, causing the lens to fall quickly. Below I took a long exposure photo to see dust in it.

In order to be more intuitive, I shot while shaking the towel to make small particles. The dust in the normal air is not so much, but the naked eye can still see the process of being sucked in, so this sealing problem needs to be improved.
