You mentioned the issue of your company's LED screen being divided into two parts. This situation is usually caused by hardware or signal settings. We can troubleshoot and resolve this from several angles. Below, I'll systematically outline the possible causes and solutions:
1. Check the Signal Source and Resolution
The most common reason for an LED screen displaying in two parts is a mismatch in resolution or signal source settings.
Troubleshooting steps:
Check the resolution output from your computer/player and ensure it matches the native resolution of the LED screen.
For example, if the screen is 3840×1080, and the output is set to 1920×1080, it may result in the screen being split horizontally or vertically.
If you are using video splicing software or an LED control system, check that the splicing settings are correct, ensuring it's in "single screen" mode, not two independent screen modes.
Solution:
Adjust the output device resolution to match the LED screen resolution.
In the LED control software, reset the screen to be a single, integrated display, not a split mode.
2. Check the LED Control Card or Wiring
LED screens generally receive signals through a control card (such as NovaStar, Linsn, etc.). If the control card settings are incorrect, it can also cause the screen to be split into two parts.
Troubleshooting steps:
Open the LED control card software and check if the screen is divided into two areas.
Check that each control card output port is correctly connected to the corresponding screen area.
Confirm that the module numbers and scanning methods are consistent for each module.
Solution:
Modify the control card configuration to combine the two parts into a single screen.
Check and adjust the wiring to ensure the signal is output from the control card to the entire screen.
3. Software/Playback Device Issues
If you are playing content through a player, the player's output mode may also cause the screen to split.
Troubleshooting steps:
Check if the player has "dual-screen mode" or "picture splitting mode" enabled.
Test playing a video with a standard resolution to see if the screen is still split.
Solution:
Adjust the player output to single-screen mode.
Or use the playback software provided with the LED control system, ensuring it is compatible with the control card.
4. Hardware Failure
In rare cases, if there is a problem with the LED module or control card, the screen may also appear to be split in two, for example:
Unstable signal reception from the module.
Damage to a control card output port.
Solution:
Replace the test module or control card port. Confirm that there are no hardware malfunctions before adjusting the software settings.
Tip:
First, use the computer to directly output a test signal to the screen to see if it still displays in two parts. This will help determine whether the problem is hardware or software related.
Record the parameters and connections for each adjustment to prevent repeated actions from causing further confusion.
