laptop to connect the projector steps
carrying a laptop to a meeting, they will use the projector, and this is now in the company to do a PPT presentation of the more common things So, the projector is often used, but what are the steps for connecting the laptop to the projector? Is it easy to connect? The following is a detailed tutorial:
a first portion, the projector RGB port
no input signal when the projector is switched to the RGB output, suggesting no RGB signal input port. First, check if the VGA cable is connected properly. If the normal description of the notebook VGA output port has no signal output, the problem is on the computer. Is the VGA port damaged? The general probability is relatively small. By consulting the data, it is found that there are generally three output modes for the notebook: 1. LCD screen output, no output on the VGA port. This is the default way, maybe consider the reasons for power saving! 2, VGA port output, no output on the screen. 3, VGA port and screen have output. Therefore, the computer must switch to the third output mode. Take Lenovo Zhaoyang notebook computer as an example, the switching mode is keyboard Fn ten. In the past, older notebooks such as Toshiba switched the hard switch on the side of the notebook.
Second, the projector information input, but no image
laptop in class certificate output mode is correct, the failure to occur should first check whether the computer's resolution and refresh rate Matches the projector. We know that laptops generally have a high hardware configuration, and the resolution and refresh rate that can be achieved are high. However, if the maximum resolution and refresh rate of the projector are exceeded, the above phenomenon will occur. The solution is very simple. Use the display adapter of the computer to lower the two parameters. The general resolution is no more than 600*800, and the refresh rate is between 60~75 Hz. Refer to the projector manual. In addition, there may be cases where the display adapter cannot be adjusted. Please re-install the original graphics driver and adjust it.
Third, the projected image cast
problem mainly VGA cable, to check whether the interface cable from the computer VGA projector tightening. If the problem still exists, then you can buy a good quality VGA cable, pay attention to the port model!
a second portion
: PC connect the projector, the PC notebook external display
machines generally used in two ways to connect the projector: the use of two graphics or video Dispenser.
dual graphics mode i.e. a PC card while the two inserted, then a display card, a card pick another projector; action video distributor is to the same video input signal into a video multiplexer Signal output.
Most laptops are designed RGB interface, an external monitor or projector.
connect the notebook display Two things to note: ①
laptop open a RGB interface
Method: turns on the display to enter BiOS provided when the computer starts, the BIOS is provided in the notebook The display (display) is both.
Method two: computer-screen display can be provided two modes in the display properties: one for the mirror mode, the other is the extension mode. When the mirror mode when using
laptop LCD screen and the projector 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 is shorthand Function (function) term, almost all of the notebook PC has a Fn key, its role is composed of keys and other key combinations, the regulation and switching hardware Features. Here you need another button. There is a notebook screen button on the keyboard button. Most notebooks are F8. Use Fn+F8 to switch.
turn require multiple switching times, generally:
first switch, a projector display, the computer is not displayed;
second switch, are displayed; < BR>
The third time, the projector does not display, the computer displays.
② resolution and refresh rate
notebook resolution and refresh rate resolution and refresh rate to confirm whether to accept the graphics settings within the range of the projector, do not know can range down a little, For example, 1024*768-75HZ.
Second, connect the notebook projector common problems and solutions
① can not play video solutions
symptoms: the notebook is Windows system, connecting the projector after use WMP, When REALPALER and Kingsoft Shadow Player play a video file, the notebook displays normally, but when projected, the video frame is black and there is no image.
reason: because of display attributes and performance do not match the projector
solutions resulting from a: Modify: Display Properties - Settings - Advanced - Performance - hardware acceleration to
hardware accelerated down on it easily solve projectors and rear-projection TV video file playback problems
solution two: slightly modified in software to play the video file can be easily resolved rear-projection TVs and projectors Video files do not play such problems properly. For the current we used several video player software, the method of introduction addressed as follows:
1: RealonePlayer
click "Tools /Preferences" menu, go to "Preferences" settings dialog box Select the "Hardware" item in the "Category" column, tick [Enable Full Screen Video Control] in the "Playback Performance" column, and then drag the slider in the "Video Card Compatibility" column to the leftmost [Most reliable] at
2: WindowsMediaPlayer
click the "tools /options" menu, go to "options" settings dialog box, select the "performance", and in the following "video acceleration" column intermediate can drag the slider, FIG setting is as follows:
3: super king
click "video /display settings /multi-display settings" menu, a "set center" In the dialog box, check [Enable multi-display split-screen display function], and check [Use hardware YUV acceleration] in the "Hardware acceleration" column.
② projector display resolution does not
symptoms: 1 screen picture is not displayed fully, or up and down or left and right, there is always room display incomplete;
2. open opportunity The progress bar and splash screen are displayed and are not displayed afterwards.
Solution: Modify the resolution of the notebook, for example, changed to 800 * 600 or less, do not use a widescreen resolution, and more. ③
projector can not display or display symptoms of incomplete
: ensuring power cable at the projector, a data signal line connected to the right circumstances, the projector lamp and the cooling fan are normal It works, but no screens in the computer are projected. Or sometimes the projection screen is not completely displayed.
reasons: because of the projector lamp and the cooling fan works properly, ruled out the possibility of failure of the projector, and the computer can be used normally, and therefore exclude the possibility of a computer failure. So, the problem may be in the signal cable or the settings of the projector and computer.
Solution: Most projectors user is using a laptop connected to it, it can not be projected may be external video port is not activated due to the notebook, then simply hold down the Fn key laptop, Then press the corresponding function key labeled LCD/CRT or display icon at the same time, and switch with the F7 key as shown below. When it is still unable to display after switching, it may be the problem of computer input resolution. In this case, just adjust the display resolution and refresh rate of the computer to the range allowed by the projector, and also pay attention to the width of the projector. High ratio setting.
Note: Although sometimes the projection screen can be displayed, but only shows a portion of the image on the computer, then the computer's output resolution may be caused by excessive, may be appropriate to reduce the resolution of your computer and then projected. If the problem persists after the above processing, 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 then it needs to be sent to the professional for maintenance.
three different projectors connected to the notebook using hotkey knowledge expansion
:
TOSHIBA → Fn + F5
