The LED video processor is the witness and key equipment for the birth, growth and maturity of the LED full-color display. Its advantages and disadvantages directly affect the display effect of the LED full-color display. The binding of the LED video processor and the display, It greatly facilitates the wide application of end users, and improves the depth of use of the LED full-color display. For users, in order to ensure efficient use, it is necessary to understand several common video processor failure solutions.

 The LED video processor is the witness and key equipment for the birth, growth and maturity of the LED full-color display. Its advantages and disadvantages directly affect the display effect of the LED full-color display. The binding of the LED video processor and the display, It greatly facilitates the wide application of end users, and improves the depth of use of the LED full-color display. Therefore, for LED full-color display technicians, it is necessary to understand several common video processor fault solutions.

  1. The problem that the LED full-color display cannot be displayed in full screen: the LED full-color display cannot display the entire image of the input signal source, but only part of the image.

  Solution: 1. Set the "Output Width" of the video processor to be the same as the LED screen width pixels, and the "Output Height" value to be the same as the LED screen height pixels. 2. When the input signal is a computer signal, it is necessary to set the video processor to the "full screen display" state.

 2. VGA input, screen offset problem phenomenon: When VGA input signal is selected, the LED screen displays screen offset. Solution: 1. Select VGA input and keep displaying VGA signal. 2. Ensure that the signal entering the VGA input port is not disturbed and the signal amplitude meets the requirements.

 3. The image of the LED full-color display screen is displayed in the center, and the screen is not satisfied. Problem phenomenon: 1. When selecting the computer input signal (VGA, DVI or HDMI, etc.), the processor setting is correct, but the computer desktop image is displayed in the center on the LED screen. 2. The output resolution of the computer graphics card is set to different values, and the input resolution of the processor LCD display is a fixed value. For example: 2048x1152_60Hz is always displayed. Reason analysis: VGA, DVI or HDMI receiving ports all contain EDID data, EDID data contains information such as all resolution formats that the interface can recognize and the best resolution format that can be recognized. After some computer graphics card is connected to the VGA, DVI or HDM port of the processor, the output resolution of the computer graphics card will default to the best resolution format recognized by the processor. The resolution set by the computer graphics card is only the resolution size of the effective image displayed, and it is displayed in the center.

 Solution: Change the graphics card VGA/DVI
