Simple steps to easily get the projector connected

Developed technology has driven the development of the computer industry, computers are available everywhere, and another device — projectors are also developing with the development of computers, and the computer is inseparable, how can two perfect devices be perfect? What's the combination? The article will give you a detailed introduction to how to connect your laptop to the projector, and easy steps to get it done.

Part 1

First, the projector RGB port has no input signal

Is the VGA cable normal? Does the notebook VGA output have no signal? These may cause the projector When switching to the RGB output, there is no signal input problem on the RGB port.

First of all, is the VGA port damaged? Generally, the probability of error in this link is relatively small, and can be excluded first.

Computer problems? There are three output modes in the general notebook computer:

1. The LCD screen output may cause the VGA port to have no output due to the power saving.

2, VGA port output, no output on the screen.

3, VGA port and screen have output. (The computer can only be connected if it is switched to the third output mode.)

Second, the projector has information input, no image input

In the case of normal laptop output, the computer Whether the resolution and refresh rate match the projector will cause the above faults to occur. Generally, the notebook computer has a higher hardware configuration, so its resolution and refresh rate are both high. Once the projector is set, the previous fault will occur. Understand the problem, the solution is very simple, generally refer to the projector manual, usually the resolution does not exceed 600 * 800, the refresh frequency is between 60 ~ 75 Hz, through the computer's display adapter down to these two parameter values ,that's it.

Third, the projection image color cast

The projection image is biased, the main problem is still on the VGA cable, it may be that the interface between the VGA cable and the computer and projector is loose. If this problem cannot be solved, you should pay attention to the model of the connection port and replace the VGA cable with a good quality.

Part 2

One: PC connected to projector, notebook external display

Using dual graphics or using video distributor is generally used when connecting a projector to a PC. Two ways.

Using dual graphics card mode: one PC is plugged into two graphics cards at the same time, one graphics card is connected to the monitor, and the other is connected to the projector;

Video splitter: is a video input signal Divided into multiple channels of the same video signal output.

Notebook connection monitor Note:

1 notebook open RGB interface

Method 1: Open in the BIOS Enter the BIOS settings when the computer starts, set the display properties of the notebook ( Display) is both.

Method 2: Setting the computer dual-screen display in the display properties can be divided into two modes: one is the mirror mode and the other is the extended mode.

When using mirror mode, the laptop LCD and projector screen display are identical.

When using the extended mode, the projector display is an extension of the main display (laptop LCD). When setting up dual screen, be sure to connect the projector or other display device in advance, otherwise it will not be set correctly. Bring up the Display Properties dialog box and select multiple monitors in the settings, ie Notebook + Projector.

Method 3: Use the function key Fn, which is the basic key of all laptops. Its function is to form a combination key with other keys to realize hardware adjustment and switching functions. The F8 is a button on the notebook screen, which is switched with Fn+F8.

Need to switch more times, generally the following conditions:

The first time you switch, the projector displays, the computer does not display;

The second switch, both display;

The third time, the projector does not display, 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 range accepted by the projector, generally at 1024*768— 75HZ between.

Second, notebook connection projector common problems and solutions

1 video screen can not play problems

Symptom: Notebook is a Windows system, connected to the projector with WMP, REALPALER and When Jinshan Shadowmaster plays a video file, the notebook displays normally, but when projected, the video frame is black and there is no image.

Cause: Display properties do not match projector performance

Solution 1: Modify: Display Properties — Settings — Advanced — Performance & mdash; Hardware Acceleration

Turn down the hardware acceleration, and the TV rear projection and projector video files will play without problems.

Solution 2: A slight modification in the software for playing the video file can easily solve the problem that the TV rear projection and the projector video file cannot be played normally. For several video playback softwares that are currently used, explain the solution separately:

1:RealonePlayer

Click the <quo;Tools/Preferences menu to enter the “Preferences” setting In the dialog box, select the “Hardware” item in the “Category” column, and tick [Enable Full Screen Video Control] in the “Playback Performance” column, and then the “Video Card Compatibility” column. Drag the slider to the leftmost [most reliable]

2:WindowsMediaPlayer

Click the “Tools/Options” menu to enter the “Options” dialog box and select “Performance" item, drag the slider to the middle in the "Video Acceleration" column below.

3: Super Jieba

Click on the “Video/Monitor Settings/Multi-Display Settings” menu, and the “Set Center” dialog box appears. Check [Start Multi-Display Points] Screen display function], at the same time in the "hardware acceleration" column, check [Use hardware YUV acceleration].

2The projector display resolution is incorrect

Symptoms: 1. The screen image display is incomplete, or up and down or left and right;

2. Open the opportunity to display the progress bar and splash screen After that, it will not be displayed.

Solution: Modify the notebook resolution, do not use widescreen resolution, you can change to 800*600 or lower.

3The projector cannot be displayed or displayed incomplete

Symptom: The projector's lamp and cooling fan are also normal when the projector's power cable and data signal cable are properly connected. It works, but no projection screen appears.

Cause: When the projector's lamp and cooling fan are working properly and the computer can be used normally, the problem may be in the signal cable or the settings of the projector and computer.

Solution: Unable to project may be caused by the external video port of the notebook being activated. Just press and hold the Fn button on the notebook and then press the corresponding function labeled LCD/CRT or monitor icon. key. When it is still unable to display after switching, it may be the problem of computer input resolution. Just adjust the display resolution and refresh rate of the computer to the range allowed by the projector, and also pay attention to the aspect ratio of the projector. setting.

Third, knowledge expansion

The function hotkey used by different notebooks to connect to the projector:

TOSHIBA→Fn+F5

IBM→Fn+F7

Compaq→Fn+F4

Gateway→Fn+F3

NEC→Fn+F3

Panasonic(Fn+F3

Fujitsu→Fn+F10

DEC→Fn+F4

Sharp→Fn+F5

Hitachi→Fn+F7

Dell→Fn+F8< Br>

Coloful→Fn+F2

Part III

After connecting the projector to the projector, press the Fn+F4 button on the keyboard. The projector can be displayed, but some After the notebook is connected to the projector, no matter what button is pressed, the projector does not display. What you need to do now is:

First, right click on the desktop - Properties - Settings - Advanced.

Second, click The title of the card to which the notebook belongs

3. Click on the notebook and monitor icon (the icon with two computer screens)

When the first icon (monitor) is clicked, the notebook will not be displayed and the projector will display

When the second icon (notebook) is clicked, the notebook is displayed and the projector is not displayed.

4. After clicking OK, the projector can be displayed.

The above detailed teaches everyone to connect the projector to the projector. The steps, do you understand, is it that the notebook is connected to the projector is also very simple. Quickly learn, there are still many places to use the notebook to connect the projector.
