The large LED screen is displayed synchronously with the computer monitor

First of all, you have a conceptual mistake, LED screen is also LCD screen, the so-called LED screen only refers to the LED backlight screen, which has the characteristics of energy saving and high brightness. LED screen is better than the old-fashioned screen,Your comparison of the two display screens is not objective,This is like a 21-inch TV box and a movie screen**The same program,You will feel that the TV is clear at the same distance**,The movie screen is particles,This is about the same。

There are two ways to solve this problem:

1. Use LED studio**, there is a "background display" function in the settings, that is, it is not synchronized with your current desktop, but note that it is still synchronized with your computer, but the display is an extended desktop, if you want to change the content, switch to the foreground.

2. Just change to an asynchronous control card, anyway, you only display simple text, and the general card can meet your requirements, which is only a few hundred yuan.

The reasons why I help you analyze are:

2.The graphics card is not set up, but yours is always used, and the appearance may be small.

3.The graphics card is broken, take a look at it with a different one.

4.The signal connection cable is not connected well (the large screen will flash, indicating that there is power).

The steps are as follows: 1. Find your own LED subtitle software on your computer first, and then open the software.

2. Then double-click the display on the left to bring up a new window of the scumbag header box.

3. Then enter the text content on the display screen and set the font to know the size.

4. Select the text content, set the center alignment, and set the font to your favorite font.

5. Then you can click "Preview" to view the effect. If it doesn't fit, keep revising it until it's appropriate. Click "Send" to send to the right.

Alternate the two pieces you want to add instead of sections. It will move on to the next program after one content is finished, as long as you set the program dwell time in the program properties correctly.

The LED display is a display carrier composed of small lamp beads displayed one by one. LED display is divided into full-color, monochrome and two-color. Generally, there are more monochrome screens for door heads, and full-color screens are generally used for indoor and outdoor large-scale advertising screens, conference rooms, and stage performances.

LED display has the advantages of seamless splicing, long-distance communication, unlimited large screen customization, and realistic colors.

LED applications can be divided into two categories: one is LED single-tube applications, including backlight LEDs, infrared LEDs, etc.; In addition, LED display, at present, there is still a certain gap between China and the international in the manufacture of LED basic materials, but as far as LED display is concerned, China's design and production technology level is basically synchronized with the international.

The original text of LCD display is liquid crystal display, which is composed of the first letter of each word, and is mostly called LCD flat panel display or liquid crystal display in Chinese. Its working principle is to take advantage of the physical characteristics of liquid crystals: when energized, the arrangement becomes orderly, so that light can easily pass through; When there is no power, the arrangement is chaotic and blocks the passage of light, to put it simply, it is to let the liquid crystal block or let the light penetrate like a floodgate.

Signal response is very important for animation and mouse movement, and this phenomenon generally only occurs on LCD LCDs, unlike CRT conventional CRT displays. The faster the signal response time, the easier it is to process the job.

Procedure: BAI

As follows: 1. First, turn on the computer

Connect the inner data cable of the DAOLED display to the computer, and then find the LED in my Rong's computer, double click to open it as shown in the picture below, and then go to the next step.

2. Secondly, after opening the software, on the menu, click Settings - Communication Settings, as shown in the figure below, and then enter the next step.

3. Then, click Screen-Program-Subtitles on the left side of the pop-up window, after opening the subtitles, you can set the text, font and time, as shown in the figure below, and then enter the next step.

4. Finally, on the menu bar above, click [Send], the LED display and the computer are successfully connected, and the synchronization can be realized, as shown in the figure below. In this way, the problem is solved.

1. First find your own LED subtitle software on the dot brain, and then open the software.

2. Then double-click the inner display on the left to bring up a new concentrating dialog window.

3. Then enter the text content in the display and set the font size.

4. Select the content of Chinese characters, set center alignment, and set the font as your favorite font.

5. Then you can click to preview the effect, and continue to modify it if it is not suitable until it is appropriate, and then click the send button to send.

That doesn't support dynamic input in the first place. It's the kind that is generally placed at the door of the store.,You can only do it on the computer with special software internals to accommodate the U disk import.。

To support dynamic input, you need to card on the motherboard, there is a transfer interface at the back, and you have to install a bunch of special software. Like a bank, there is a special computer responsible for calling numbers and multiple screen displays, which is a set of systems and is not cheap.

LED screens have data sockets, which are the common sockets with fastening screws in the three rows of pinholes. If you are a desktop computer, buy a plug-and-drop computer to connect your usual display and LED, if it is a laptop, there will be a special socket for external screens next to or behind. It shouldn't have anything to do with the USB flash drive.

Just do a good job of data connection processing.

LED displays are generally divided into three types: single primary color, double primary color and color screen, and the connection methods of LED displays and computers are also different. Expert.

1 Once both monitors are connected, press the Windows P key on the keyboard at the same time, and four mode options will appear on one side or in the middle of the screen.

2 If both monitors display asynchronous content, simply select Extended mode.

Precautions: 1) Computer screen:

In this mode, an external second monitor or projector will turn off the image output and only show the computer's home screen.

2) Copy: In this mode, the image of the main display is copied to the second display, and the image output of the two displays is synchronized.

3) Expansion: Often referred to as the dual-screen expansion mode, where the primary screen and the second screen can be used for different image outputs. Move your mouse between different screens and switch between the primary and secondary screens.

4) Second screen (or projector mode):

In this mode, the computer's home screen is turned off and black, and the second screen becomes the home screen.

You can try to right-click on the desktop to enter the properties.,There's something similar to the balance of the left and right screens in the screen.,It's also related to the resolution or something, you can see it right away, it's two screens, one is 1, one is 2, just adjust that thing, go and see it, I'm not very clear, it's as much as you help, hehe, it's like the f7 of the keyboard is switching, go and try it.。

You're using Lingxinyu's LED control card

Use a cable to connect with DVI, and it's OK to connect it.
