With the continuous development of projection technology, more and more brands are involved in the projection market. Projectors are widely used in homes, offices, schools and entertainment venues. Most people may not know how to use the projector. So how to use the projector correctly? Then let's get to know it together.
Step one: Connect the projector and laptop
1. Connect the laptop to the projector, press the power key to turn on the projector, and switch the computer screen to the projector.
2. It should be noted here that it is better to use the original cable when the projector is used. The length of the signal cable is generally not more than 15 meters. If it is too long, it will cause signal attenuation.
3. For the Windows XP laptop, open the laptop and press the keyboard combination (Fn+F7) to switch the computer screen to the projector. Fn is a function key, and F7 is a computer screen output key. Due to the differences in the brand notebook computers, the output keys vary, so depending on the specific laptop.
Step 2: Switch Projector and Monitor Screens
1. The output button is normally one of F1 to F12 and has a small computer icon above it. The output key of most brands of laptops on the market is F7.
2, for the windows 7 system laptop, the screen switch key combination: Windows + P, press the key combination after the emergence of rapid projection management, so press the left and right arrow keys to select.
3. At this time, you can see four options: "Computer only," "Copy," "Extended," and "Projector only." "Computer only" does not switch to an external monitor or projector. "Copy" shows the same content on both the computer and the projector. "Extension" means to increase the display space of your notebook display and make the notebook display larger. You can put more windows on the desktop. The "projector only" screen is not displayed on the laptop itself.
Step 3: Adjust the screen of the projector
1. When using the projector, you can adjust the size of the screen by moving the “size key†left and right according to actual needs. If the screen is distorted, you can raise (or lower) the height of the projection properly or press the “keystone adjustment key†to adjust the screen. .
2. After the projector is used, press the projector power “ON†key, the prompt on the screen whether to turn off the projector appears, choose to close, and press “Confirm†to confirm.
3. At this time, please note that the power cord must not be unplugged immediately. When the projector is turned off, it will take some time to dissipate heat. At this time, the cooling fan will run quickly until the fan stops running. .
4. If the projector is turned off immediately after the projector is turned off, the projector will not be able to dissipate heat in time, which will seriously damage the hardware and its service life. Therefore, it is necessary to pay more attention to this during the use of the projector.
Having said so much, everyone knows about the projector. It is very important to choose a projector with good quality. It is recommended that you go to the Kelipu Mall under Chenguang, and the factory outlets are of good quality.
