How to connect the projector to the desktop?

The desktop should be connected with a projector! So what method should be used to connect? Let me give you a detailed introduction on how to connect the desktop and projector! I hope it helps you!

How to connect the desktop to the projector 1:

Through the iphone? Personal? Hotspots can be shared with computers through wireless, Bluetooth or USB, so that computers can surf the Internet through mobile phones.

Open it? Establish a cellular mobile network? , open? Cellular mobile data? And then what? Enable 3G? ;

Open it? Set personal hotspots? , open? Personal hotspot? In the pop-up dialog box, select * * * sharing mode. If wireless and Bluetooth * * * sharing are enabled, what can I set? Wireless LAN? Password;

If wireless mode is used, what is the wireless signal sent by iphone? An overview of the setup of this machine? Put it in. The computer needs a wireless network card. If you search for your iphone signal, you can enter the correct password to connect.

Method 2 for connecting a desktop to a projector:

1. Confirm the connector between the connecting cable and the projector? Settings? Video input? Whether it is consistent, such as using VGA interface, video input settings must also be VGA. Projectors generally have input settings such as HDMI, S-terminal, DVI and AV input. If the projector doesn't have intelligent recognition ability and is set incorrectly, it won't produce an image anyway.

2. Confirm the maximum resolution supported by the projector. If the projector supports 1280*720 or 640*480 or 1024*768 at maximum, and the resolution set by your desktop computer is 1980* 1080, then the projector is generally unresponsive, so adjust the resolution to 800 *. If an image appears, this is the problem.

Third, speaking of which, if the problem has not been solved, I think the latter problem is more complicated. That depends on what the desktop graphics card is. Different graphics cards have different settings, and different operating systems have different settings. Therefore, the graphics card settings need to match the function settings of the graphics card driver. I haven't set how to play these settings for a long time. Basically speaking, is XP or WIN7 in the control panel? Show? This is done in the scene.

Method 3 for connecting a desktop to a projector:

1. Press and hold the Windows icon key +p on the keyboard.

2. Select the display mode in the above figure:

Computers only, which means turning off the projector.

Only the projector means turning off the computer monitor.

Copying means that the computer monitor and projector display the same content.

Expansion means that computer monitors and projectors display different contents.

Projector classification

1, home theater type: it is characterized by a brightness of about 2000 lumens (this number is increasing with the development of projection, and the contrast is high), and the aspect ratio of the projected picture is mostly 16: 9, and various video ports are complete, which is suitable for playing movies and HDTV, and suitable for home users.

2. Portable business projector: Generally, a projector weighing less than 2kg is defined as a business portable projector, which is comparable to a thin notebook computer. Business portable projector has the advantages of small size, light weight and strong mobility, and is a substitute for traditional slide projectors and large and medium-sized projectors. The combination of thin notebook computer and business portable projector is the first choice for mobile business users to demonstrate mobile business.

3. Educational conference projector: generally used in schools and enterprises, with mainstream resolution and brightness of about 2000-3000 lumens, moderate weight, good heat dissipation and dust prevention, suitable for installation and short-distance movement, rich functional interfaces, easy maintenance, relatively high cost performance, and suitable for public purchase and promotion.

4. Mainstream engineering projector: Compared with mainstream ordinary projectors, engineering projectors have larger projection area, longer distance and higher brightness, generally support multi-bulb mode, and can better cope with large and changeable installation environment, which is very suitable for education, media and government.

5. Professional cinema projectors: This kind of projectors pay more attention to stability and low failure rate, and have strong heat dissipation performance, network function and ease of use. Of course, in order to adapt to various professional applications, the most important feature of film instrument is high brightness, which can generally reach more than 5000 lumens, and the highest can exceed 10000 lumens. Because of its huge size and heavy weight, it is usually used for special purposes, such as theaters, museums, great halls and public areas, and can also be used for traffic monitoring, public security command centers, fire fighting and air traffic control centers.

6. Measuring projector: This projector is different from the above projector. It was called contour projector in the early days. With the popularization of grating ruler, projectors are equipped with high-precision grating ruler, so people call it measuring projector (or projector, such as CPJ-30 15 produced by Gaocheng Company). In order to distinguish it from traditional projectors, this kind of projector is called measuring projector. Its main function is to form an enlarged projector through the transmission of light, and then determine the size of the product with standard film or grating ruler. Due to the development of industrialization, this measuring projector has become one of the most commonly used detection instruments in manufacturing industry. Punctual projection is divided into vertical projector and horizontal projector. According to different contrast standards, it can be divided into contour projector and digital projector.
