The main reasons for black edges appearing during gaming can be summarized as follows:
1. Resolution mismatch: Black edges may appear when the resolution setting of the game does not match the actual resolution of the LED display or monitor. This is because the game screen cannot completely fill the entire screen area, leaving black blanks at the edges.
2. Game setting issues: Some games may have specific display setting options, such as window mode or full-screen mode. If the window mode is set and the window size is not adjusted correctly, or the resolution in full-screen mode is set improperly, black edges may occur.
3. Monitor setting issues: Improper display scaling settings or display mode selection of the monitor may also cause the game screen to not be fully displayed, resulting in black edges. For example, if the display scaling ratio is set too high or too low, the game screen may not fit the screen.
4. Driver issues: Outdated or unstable graphics card drivers may also cause abnormal display of game screens, including black edges. Ensuring that the graphics card driver is updated to the latest version can help resolve such issues.
To sum up, to solve the black edge problem during the game, you can try to adjust the resolution settings of the game and monitor, check the display mode of the game and monitor, and update the graphics card driver.
