How to use the LED display screen when it is connected to the computer?
'One' After the computer is projected onto the LED large screen, there is a small screen at the top corner of the screen. How to turn it off?
After the computer is projected onto the LED screen, if the top-left corner of the screen has a small screen that needs to be turned off, simply turn it off directly.
The reason for the "2nd" LED screen's image display being different from the normal screen
The solution steps are as follows:
If it's referring to a TV set, this is a problem with the program channels. If it's a computer monitor, it's an issue with the incorrect settings of the monitor.
2. When selecting the input signal for the computer (such as VGA, DVI or HDMI, etc.), the processor settings are correct, but the computer desktop image is centered and displayed on the LED screen.
3. The output resolution setting of the computer graphics card varies, while the input resolution displayed on the processor LCD remains a fixed value. For example, it always shows 2048x1152_60Hz.
4. Change the scaling options for the VGA/DVI/HDMI output of the graphics card, and set it to scale so that the output is full screen. During work, it was found that for different graphics cards, different operating systems, and even different versions of the operating system, the location of this setting in the system is also different. We have summarized the detailed steps for graphics card settings in common XP and WIN7 systems as follows:
5. For a notebook with NVIDIA and INTEL dual graphics cards running Windows 7, right-click on the blank area of the desktop. In the pop-up menu, select "Graphics Options" → "Screen Adaptation" → "Digital Television" → "Full Screen Zoom". Then, the DVI signal will be set to full-screen output.
6. Right-click on the blank area of the desktop. From the pop-up menu, select "Graphics Properties". Then, go to the Intel Graphics and Media Control Panel. Under the "Display" → "General Settings" menu, select the digital display of the monitor. Set the zoom option to Custom Aspect Ratio, and set both the width and height to 100%.
7. For the ATI graphics card in the WinXP system, right-click on the blank area of the desktop. From the pop-up menu, select "ATI Control Panel". Then, in the ATI Control Panel, choose "Digital Panel [DVI]" → "Zoom Options", and set it to "Over-scan 0%". In this way, the DVI signal will be set to full-screen output.
8. For the ATI graphics card in the WIN7 system, right-click on the blank area of the desktop. From the pop-up menu, select "ATI Control Panel". Then, in the ATI Control Panel, choose "My Digital Plane Panel" → "Zoom Options (Digital Plane Panel)". Set it to "Over Scan 0%", and the DVI signal will be set to full-screen output.

How to project the 'Lu' LED screen
LED cannot be projected onto a screen.
The so-called screen projection refers to the projection of a mobile phone onto a screen. This means on a network TV, you find the application, enter it, then find the option for mobile phone projection, and then project the mobile phone onto the TV that is connected to it. LED cannot be projected onto a screen because it relies on signals sent by a computer. It can also use signals from a USB drive.
Why can't the image on the 'QI' LED display be adjusted to the same size as that on the computer screen?
Abstract: Dear user, the resolution of the computer display is different from that of the LED display, resulting in variations in screen size. Please follow the steps below to make the adjustment.
"How to use the 'EIGHT' computer LED projection screen software"
How to project the mobile phone screen onto a computer? What screen projection software is used for mobile phone live streaming? In daily life, many people like to project their mobile phones onto computers, either because the phone screen is too small, or because they want to conduct live streaming by projecting the phone screen onto a computer. In fact, there are far more than one way to project a mobile phone onto a computer. Today, I will share with you the four most commonly used ways of projecting a mobile phone onto a computer.
1. Using the built-in screen projection function of the mobile phone
With the gradual enrichment of mobile phone functions, there have been mobile phone models with built-in screen projection functions on the market. Apple's AirPlay is very familiar to everyone. This mirror projection method has been available in the iOS system for a long time and can project to televisions, computers, LED, etc. It can simultaneously transmit the phone sound and picture to the computer.
In addition, there are some mobile phone models with built-in screen projection functions, such as the Black Shark phone with Black Shark Projection. However, the supported mobile phone models are limited, and the operation is relatively more complex:
2. Utilizing the built-in screen projection function of the Windows 10 system on the computer
By using the built-in screen projection function of Windows 10 and the multi-screen interaction function of the Android phone, the sound and picture of the phone can also be transmitted to the computer. The specific operation is as follows:
Computer Windows 10 system side:
1) Click "Start" - "Settings" - "System" - "Projection" - "Connect to a wireless display"
2) In "When you agree", in the "Project to this computer" option, select "Available anywhere on a secure network", and it is recommended to change the network configuration file of the connected wireless network to "Private" at this time (method: Open "Network and Internet", "Change connection properties").
Android phone side:
Search for "Multi-screen Interaction" in the settings or global search bar. Open Multi-screen Interaction for device search, and click the searched device. The projection can be run in this way. Note: This projection method requires both the mobile phone and the computer to be in the same network Wi-Fi. Also, I would like to mention that this projection method of Windows 10 is personally felt to have an average effect, and the sound is not very stable.
3. Connecting with a Type-C to HDMI data cable for projection
In addition to the mobile phone and computer, you also need a Type-C to HDMI cable with dual USB interfaces (universal for Android and iOS) and a transmission interface for audio and video data. There is such a cable on Taobao. Connect the two ends to the mobile phone and the computer respectively, and project through a wired connection. You can also project the sound and picture of the mobile phone simultaneously to the computer:
4. Downloading screen projection software
As the name suggests, it is necessary to install a screen projection software on your computer. This is the simplest and most common way for Android phones. There are many Android screen projection software available on the network. The two most popular ones for personal live streaming games are Android Screen Projection Master and TC Games Projection.
One is because these two projection methods can be combined with a speaker plug in the ear hole of the mobile phone to transmit the mobile phone sound to the computer and are more stable than wireless transmission. While using TC Games Projection, you can also choose whether to need to operate the game with keyboard and mouse while projecting, and it can be matched with the mobile phone player, which is more suitable for game rebuying.
Generally, screen projection software will simultaneously support Wi-Fi (the mobile phone and computer need to be in the same local area network) and USB connection. For users without an ear hole in the mobile phone, Wi-Fi connection is relatively more convenient. However, personally, I think USB connection is relatively more stable and will not be affected by the network environment.
The 'Jiu' computer screen has been expanded to an LED display screen.
The method to connect the notebook to the LED display:
Right-click on the "Properties" in the system desktop with the mouse.
Enter the "Display Properties".
Then select the "Options" tab.
In the "Display Devices" section, choose the model of your LCD TV and select the corresponding resolution, such as 1280×720 or 1920×1080, and check the option "Extend Windows desktop to this display" to prevent the image from distorting when displaying the content from the notebook.
Also, if you want to simultaneously transfer the audio from the notebook to the LCD TV, you need to activate the "HDMI Audio" device in the "Device Manager". This way, you can use HDMI for both audio and video transmission.
If the notebook does not have an HDMI interface, then you need to use the traditional CRT video cable and AUX audio cable to connect the notebook and the LCD TV. These interfaces are easy to find. There is a blue 15-pin D-type interface on the notebook for CRT output, and the LCD TV will also have the same interface. Connect them with special cables; for audio, use two 3.5mm audio transmission cables. The video settings are the same as for HDMI, while for audio, select the "Normal Sound Card" in the "Device Manager" and do not need to activate the HDMI sound card.
