Connect the projector

Can a mobile phone be connected to a projector?

First of all, we need to power on the wireless projection collaboration system and connect the host of the wireless projection collaboration system with the HDMI interface of the LCD screen (projector) through HDMI wiring. 2. After the connection, we find the access channel in the setting interface of the display screen and select the channel we want to connect; Third, connect the mobile phone Android machine: After the wireless projection system is successfully set up, we can find the equipment being used in the wireless projection setting bar of the mobile phone and select the connection.

Mac: Because Mac doesn't support miracast on-screen protocol, we can't link directly like using Android, but we can link WiFi the signal sent by wireless projection collaboration system through AirPlay on-screen protocol. Fourth, play what you want to play, and the wireless projection of the mobile phone is completed.

Extended data:

A projector is an optical instrument, which uses optical elements to enlarge the outline of a workpiece and project it onto a screen. The profile can be measured by transmitted light, and the surface shape of blind holes and the surface of parts can also be measured by reflected light.

The projector is especially suitable for measuring complex contours and small workpieces, such as clock parts, stamping parts, electronic components, templates, molds, threads, gears and molding tools, with high detection efficiency and convenient use. Widely used in measuring rooms and production workshops, especially for instruments and watches. References:

How to connect the mobile phone with the projector? There are several ways.

The first type: wireless screen projection

The requirement of wireless screen projection is that the display device must support the wireless screen projection function and the wireless network should be stable enough.

1. Turn on the projector, find the wireless projection screen, and turn on the Wi-Fi display function. Different projectors have different settings, but they are all the same.

2. Turn on the mobile phone's wifi, search for the wifi signal sent by the TV/projector, find and click on wifi to establish a connection. After the connection is successfully established, the picture on the mobile phone can be directly projected on the TV/projector.

The second type: screen projection through Type-c to HDMI line.

It has gradually become a popular trend for mobile phones to adopt the latest Type-c interface. Now all new mobile phones are basically Type-c interfaces.

Yes Therefore, it is a convenient and quick method to convert Type-c into HDMI and directly project the screen one line.

However, the mobile phones supported by this scheme are limited. As far as we know, only Huawei Mate 10 released earlier can support the screen projection function.

1. Insert the Type-c terminal directly into Mate 10 mobile phone, and the HDMI port directly into the TV/projector.

2. After the connection is successful, the mobile phone will automatically pop up a prompt, which can simulate the keyboard, mouse and computer modes.

3. Pull down directly, click the corresponding mode, and the screen projection is successful directly, without setting anything.

Turn on your mobile phone WIFI and connect the same WIFI as the projector. 6. Then click to open the AirPlay mirror function of the mobile phone.

7. Select "Letou E6" to connect in this way. Extended data:

Tips for choosing a projector 1. Make clear the nature of the signal source to be displayed, that is, what is its line frequency and what graphics card is output by.

According to the nature of the display source, projectors can be mainly divided into ordinary video machines and digital machines. When only a complete TV signal is displayed, such as playing a video tape in a karaoke hall, you can choose an ordinary video player; To display the signal output by VGA card, you can choose a digital machine.

2. Confirm the installation method The projector installation method is divided into desktop orthographic projection, ceiling orthographic projection, desktop rear projection and ceiling rear projection. The front projection is that the projector and the audience are on one side; The rear projection is that the projector and the audience are at the two ends of the screen respectively.

If it is temporary use, you can choose the countertop ceiling method. If the space is large and the civil works are arranged as a whole, the overall effect of choosing the rear projection method is the best. If the space is small, you can choose the method of back projection refraction.

3. Understand the display environment, such as indoor area, lighting, etc. If the indoor area is within 100 square meter, the exhibition area is moderate, there is no sunlight, and the lights are dim, you can choose a projector with a brightness of about 2000-3500 lumens. When the ambient light is bright and used in a spacious place with a large display area, you need to choose a projector with high display resolution and high brightness, and you can choose a high brightness projector with 3000-6000 lumens.

4. On-site projector purchase skills 1). Check the horizontal scanning tracking frequency range. According to the horizontal scanning frequency range given in the technical index, select high, medium and low frequencies, and calculate the image resolution corresponding to the three frequencies. Check whether the projector can display normally under these three resolutions.

If the lines are not synchronized, that is, the picture is distorted or dithered, it indicates that the horizontal scanning tracking is poor. 2) Check the focusing performance of the test grid generated in the projector or the test grid generated by the signal generator or computer, adjust the focus to the best position, change the image contrast from low to high, and observe whether the horizontal and vertical lines of the grid are out of focus.

If so, the focusing performance is poor. 3), check the video bandwidth video bandwidth directly affects the details of the video.

Use a computer or signal generator to generate a white background graphic signal with the highest resolution that the projector can achieve, and observe whether the smallest character graphic on the screen is clear. For example, when the video bandwidth of the projector is insufficient, the horizontal lines displayed on the screen are solid, while the vertical lines are weak and the image details are blurred.

How to connect a mobile phone to a projector

How do you connect your mobile phone? Can the conditions be more detailed? This is too general, because even if the projector can be connected to the mobile phone, it depends on the model of the mobile phone. Because the projector is connected to the mobile phone, the mobile phone needs to have HDMI interface or MHL interface. You need to know whether your mobile phone has these interfaces. However, ordinary smart phones have this function, but when you buy a projector, make sure you have it, otherwise it will be very troublesome. There are many projectors that can be connected to mobile phones, but if you say you have used them, I have only used Weijie DL-S80. It's simple. Handheld projectors require mobile phones to have HDMI interface or MHL interface. The operation is simple, just connect the data cable and you can use it. The square white projector looks good. I think the projection effect is good. In fact, if there are conditions, I still hope to go directly to the physical store to see the effect, so there is definitely no problem.

If you are satisfied, please accept it.

How does the computer connect to the projector?

How to connect the projector to the computer? There are several ways: First, there are generally two ways to connect a PC and a projector: using dual graphics cards or using a video distributor.

Use dual graphics cards, that is, a PC is plugged with two graphics cards at the same time, one graphics card is connected to the monitor and the other is connected to the projector; The function of video distributor is to divide a video input signal into multiple identical video signals for output. Most laptops are designed with RGB interface, which can be connected to a monitor or projector.

Notebook should pay attention to two points when connecting to the monitor: ① Open RGB interface for notebook ② Method 1: Open it in BIOS, enter BIOS settings when the computer starts, and set the display properties of notebook to both. ③ Method 2: Set the computer dual-screen display in the display properties and divide it into two modes: one is mirror mode and the other is extended mode.

When using mirror mode, the laptop LCD and projector screen display are exactly the same. When using the extended mode, the projector display is an extension of the main display (laptop LCD).

When setting up dual screens, be sure to connect the projector or other display equipment in advance, otherwise it will not be set up correctly. Bring up the display properties dialog box, and select multiple monitors in the settings, namely notebook+projector.

④ Method 3: Using the Function key Fn is the abbreviation of the word function. Almost all notebook computers have Fn keys, which are used to combine with other keys to realize hardware adjustment and switching functions. We need another key here. There is a notebook screen button on the keyboard button, and Lenovo notebook is F4. Switch with Fn+F4.

⑤ Generally, it needs to be switched several times :⑤The projector displays for the first time, but the computer does not display; All landowners switch for the second time, all display; ⑧ Switch on for the third time, the projector does not display, and the computer displays. 2 Resolution and refresh rate The resolution and refresh rate of the notebook confirm whether the resolution and refresh rate set by the graphics card are within the acceptable range of the projector. I wonder if the range can be reduced, such as 1024 * 768-75hz.

Second, the notebook is connected to the projector. Common problems and solutions ① Solutions that cannot play videos Symptoms: The notebook is a Windows system. After the projector is connected, when the video file is played by WMP, REALPALER and kingplayer, it will be displayed normally in the notebook, but the video picture is black when projected, and there is no image. Reason: Scheme 1: Modification: Display Properties-Settings-Advanced-Performance-Hardware Acceleration. Easily solve the video file playing problem of TV rear projection and projector. Solution 2: It is easy to solve the problem that the video files of TV rear projection and projector can not be played normally by slightly modifying the software for playing video files.

Aiming at several commonly used video playback software, this paper introduces the following solutions: 1. Realone Player clicks the "Tools/Preferences" menu, enters the "Preferences" setting dialog box, selects the "Hardware" item in the "Category" column, unchecks the "Playback Performance" column, and enables full-screen video control. Then drag the slider in the "Graphics Card Compatibility" column to the most reliable position on the left. 2.Windows Media Player clicks the "Tools/Options" menu, enters the "Options" setting dialog box, selects the "Performance" item, and drags the slider to the middle of the "Video Acceleration" column below. The specific settings are as follows: 3. Click the "Video/Monitor Settings/Multi-Monitor Settings" menu of Super Street Fighter. ② Symptoms of incorrect projector display resolution: 1. The screen display is incomplete, or up and down or left and right, and in some places it is always incomplete; 2. The progress bar and the startup screen will be displayed at the first time, and then they will not be displayed.

Solution: modify the notebook resolution, such as 800*600 or lower, do not use widescreen resolution and so on. ③ The projector can't display or display incomplete symptoms: When the power cord and data signal line of the projector are connected correctly, the light bulb and cooling fan of the projector also work normally, but there is no picture projected from the computer.

Or sometimes the projection screen display is incomplete. Reason: Because the light bulb and cooling fan of the projector can work normally, the possibility of projector failure is ruled out, and the computer can also be used normally, so the possibility of computer failure is also ruled out.

Then, the problem may be in the signal connection line, or in the settings of the projector and computer. Solution: Most projector users are connected with laptops, so the external video port of the laptop may not be activated. At this time, just press and hold the Fn key of the notebook computer, and then press the corresponding function key labeled LCD/CRT or display icon at the same time, as shown in the figure below, to switch.

If it still can't be displayed after switching, there may be something wrong with the input resolution of the computer. At this time, just adjust the display resolution and refresh rate of the computer to the range allowed by the projector, and pay attention to the setting of the height-width ratio of the projector. Note: Sometimes, although the projection screen can be displayed, only a part of the image is displayed on the computer. At this time, it may be caused by the high output resolution of the computer, so the resolution of the computer can be reduced appropriately before projection.

If the problem still exists after the above treatment, it may be that the LCD panel of the LCD projector has been damaged or the DMD chip in the DLP projector has been damaged and needs professional maintenance. Third, expand knowledge. Function hotkeys used by different notebooks to connect to the projector: paq→Fn+F4 DEC→Fn+F4 Sharp →Fn+F5 After the notebook is connected to the projector, press the Fn+F4 key on the keyboard (depending on the notebook model, note that F4 or other keys have a small box on them). However, no matter what key is pressed, some notebooks are connected to the projector, and the projector will not display. Now take Sony notebook as an example to explain the solution.

1. Right-click the desktop-Properties-Settings-Advanced-Mobile GMA Driver-Graphics Properties. (Set after connecting the projector) 2. Click the title of the graphics card to which the notebook belongs; 3. Click on the notebook and monitor chart.

How does the computer connect to the projector?

1, there is a VGA with an external interface in general notebooks. Connect it here. See if FN+F is used on the computer? Just change it. (f(k & amp； Y6 g4 F, for example']

2. If it is not displayed, it may be that the resolution of the computer is too high. It is suggested to set it to 1024*768 or 800*600 first, which will generally work.

FN+F？ Generally, it is FN+F7, and there are FN+F3, FN+F2, etc. It varies from book to book.

Dual-screen display: notebook/bbyy/htm2009/20090518 _ 626788 _ 2.shtml.

1. Connect with VGA data cable: the output port of the notebook is VGA, which is a trapezoidal socket with 15 hole; The input port of the projector is also 15 hole, which means input. Don't plug it into the OUT, and then select the information input of the projector menu: VGA 1, computer 1, RGB 1.

2. If the projection is not displayed, please press the switch key. Fn+ function key F 1-F 10 (LCD/CRT, or an icon of a small TV), the projection mode can be switched separately for three times. Notebook display alone/notebook+projector dual-screen display/projection should be displayed separately in three modes.

It is useless for some notebooks to press the switch combination key. Then right-click on the computer desktop to see if there is "graphics card settings" (such as NVIDIA control panel). There are three projection modes. Select one of them: PC/PC+monitor/monitor or LCD/LCD+CRT/CRT.

4. Don't set the resolution of notebook graphics card too high. The projection is set to 1024*768, which is the standard projection mode of 4:3. After using the projection, set it back to the optimal resolution of the laptop.

Doing the above four points will basically solve the problem. If not, please continue reading:

5. Right-click on the computer desktop and click Properties-Device-Advanced to find the graphics card settings, including external display and notebook display modes. Select what you want (here: general, color management, adapter, monitor, troubleshooting, etc. ) and graphics card settings. The above must be done under the condition that the graphics card driver is correct and safe. Many people have your questions. Go to the official download driver, choose full installation, and find someone who understands the computer.

6. Frequently asked questions about projectors and laptops

(1.) After connection, the projection screen flashes and the font flashes. Solution: change the cable, the computer and projector power share the ground wire, or do not use notes when charging.

(2) During the screening, the movie will be played. There is only a player in the projector screen, so you can't play movies? Solution: Right-click on the computer desktop and click Properties-Device-Advanced to find the graphics card settings, which include the modes of external display and notebook display. Choose what you want. (Here: General, Color Management, Adapter, Monitor, Troubleshooting, etc. ) Just turn on Troubleshooting to speed up and turn down the hardware.

(3) When projecting, there is no desktop icon on the projector screen, only desktop background? Solution: Right-click the blank space of the desktop, select "Properties" to enter, click the "Settings" tab, select the monitor 1 at the top, and check "Extend the Windows desktop to this monitor" at the bottom.

How to connect the mobile phone with the projector?

The popularity of smart phones has also promoted the development of mini-projector. Can a mobile phone be connected to a projector? How to connect the projector? Xiaoshuai Cinema summarized the following connection methods of portable projectors: 1. 1. The output functions of some mobile phones are summarized as follows: AV output, MHL output function (HD audio-visual standard interface of mobile terminal is a standard audio-visual interface developed at present, which is convenient for connecting portable consumer electronic devices. MHL only uses one signal line, and the picture can be clearly presented on the TV through the standard HDMI input interface.

It uses the existing Micro USB interface, whether it is a mobile phone, a digital camera, a digital video camera or a portable multimedia player. It can transmit the complete media content directly to TV through MHL line without destroying the effect of the film itself. You can connect all our projection products with AV video input and HDMI input through data cables.

Apple mobile phone has the function of HDMI video output, so you can directly connect the HDMI interface output of mini projector DL-S09 with an HDMI patch cord, and you can find the corresponding data cable connection or the corresponding patch cord pair according to what kind of interface your mobile phone has. Samsung mobile phones have HDMI video output, or MHL. You can also use the HDMI patch cord to connect the output of the projector DL-S80 to project the picture.

2. Wireless connection conditions through Mirrorop software: the projector must be an Android smart projector, such as JX-105; Or the projector has built-in wireless connection software, such as DL-S09. Neither of the above situations is correct. If you can't connect to the network without your own system, you can buy a smart stick to connect to the mini projector, because to connect wirelessly, both parties must be able to connect to the network. At present, smartphone version 2.3 and above can be installed by searching for the appropriate mirrorop sender mirrorop receiver client on the Internet: WindowsMac (Apple Computer System), Android phone/ipad blackberry mirror op receiver application system: Windows Receiver downloads these two kinds of software on mobile phone and mini-projector respectively, the blue one is installed on mobile phone hill to send software, and the red one is installed on mini-projector to receive software.

After installing these two softwares respectively, you can connect the mobile phone and mini-projector wirelessly. Of course, there is also an environmental condition that must be carried out under the condition of WIFI. This is a mobile phone wirelessly connected to the projector, and data can be transmitted wirelessly.

Very convenient and free. PS: 1。 Apple phone must be a jailbreak phone to download this software. Add the mirrorop/reop address in CYDIA's "software source" and download it. After the installation is completed, the phone will be restarted, and then the mirrorop transmitter icon will be displayed on the phone, and then it will run simultaneously with the machine with the mirrorop receiver installed.

2. you need to register the mirrorop sender software. You don't need to register, and you can connect wirelessly for five minutes for free. The above are several ways to connect the mobile phone to the projector at present. You can choose the connection method you need according to your actual situation.

How to connect the projector to the computer, please give an example, thank you.

The connection steps are as follows: 1. First, connect the video input interface of the projector to the video output interface of the notebook computer.

2. The video input interface of the projector must be connected to the video output interface of the notebook computer, and then the picture on the current notebook computer will appear on the projector. 3. Open the computer desktop and right-click to open the screen resolution option.

4. Enter the interface for changing the appearance of the monitor, and click "Connect projector". 5. Then, we open the related setting options.

What needs our attention is that you can use shortcut keys, press the Microsoft logo key and the P key to quickly open the relevant settings displayed by the projector. 6. Selecting "Computer Only" means that the image will not be displayed on the projector, and the computer will not output the image to the projector; If we choose "projector only", the computer will turn off the image output on its monitor, which is beneficial to energy saving in some cases.

As for copying, the resolution display output on the projector and computer is exactly the same; There is also an extended function. We can put the image output by one monitor on two monitors, or we can adjust the resolutions of these two different monitors differently, which needs to be adjusted according to actual needs. 7. In general, we use a projector to show PPT or some video manuscripts. For specific settings, we can make different display adjustments on the screen resolution. Here you can refer to the setup process of your own monitor.

Precautions for connecting the extended data computer to the projector: 1. Before connecting the projector and the notebook, be sure to turn off the projector and the notebook, otherwise it may cause serious consequences, and the interface between the notebook and the projector may burn out. 2. Insert the blue plug (APG) on the chassis into the corresponding APG interface on the notebook and tighten it.

If you need a notebook computer with sound output, plug the audio cable on the chassis into the corresponding interface. Green is the audio interface and red is the microphone interface. 3. After all interfaces are connected, turn on the power.

Turn on the projector first, click the button on the control panel of the notebook after turning on the projector, and then turn on the computer to let the projector receive the computer signal. After use, you can turn off the computer and projector together, then unplug the connector and turn off the power.

4. If there is still no signal after the computer is turned on, switch the signal. Many users connect the projector to the laptop and turn it on, but the projector can't display the notebook picture. This may be whether the laptop is connected to a projector or needs to be switched. At this time, just press and hold the Fn (function key) of the notebook computer, and then press the corresponding function key marked LCD/CRT or display icon at the same time to switch.

How to connect computers and projectors, and how to connect different computers.

In order to connect the projector correctly, let's first understand the various interfaces on the laptop:

1, HDMI interface and connecting cable:
