So how does the laptop connect to the projector? What if there is no signal when the laptop is connected to the projector? In fact, the process of connecting the projector and the notebook is very simple. Let's look at the introduction first. How to connect a laptop with a projector What if there is no signal on the laptop?

When you need to use a projector, it is really not a good thing that the projector is connected to the notebook without signal failure, and it will be very troublesome to delay business. Let's look at the solution, which can also be used in an emergency.

First, the projector connected to the notebook without signal solution

2. Connect the projector signal line to the notebook computer;

3. Turn on the projector;

4. If it cannot be displayed, press the following function keys according to different laptop models: Dell: fn+F8hp: fn+F4 ThinkPad: fn+F7 Toshiba: fn+F5 Acer: fn+F5 Fujitsu: fn+f 10 Samsung: fn+F4 Sony: fn+F7 Asustek: fn+F8;

5. If it can no longer be displayed, please adjust the display resolution (1024×768, 800×600, etc. ) in the display properties; Set the display refresh frequency (usually 75HZ) through Display → Settings → Advanced → Monitor.

Second, how to connect the notebook to the projector

1. First, you must connect the video input interface of the projector to the video output interface of the laptop, and then the picture on the current laptop will appear on the projector.

2. Then right-click to open the screen resolution option, and here we click "Connect projector".

3. 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.

4. If selecting "Only Computer" means that the image will not be displayed on the projector, 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.

Under normal circumstances, we use the 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.
