Screen casting – Why does the computer screen casting lag? How to solve it?

There are many reasons for computer screen mirroring lag, and the following are some possible reasons and corresponding solutions:

  1. Insufficient computer performance: The hardware performance of the computer, such as processor, memory, and graphics card, has a significant impact on the screen projection effect. If the computer’s performance is low, it may cause screen mirroring to lag. The solution is to replace a more powerful computer or close some unnecessary programs during screen mirroring to free up hardware resources.
  2. Screen casting software issues: The stability, compatibility, and improper settings of the screen casting software may also cause screen casting lag. The solution is to update the projection software, reinstall or adjust the software settings to improve the projection effect.
  3. Network issues: Unstable network, slow network speed, network congestion, and other issues can also cause screen mirroring lag. The solution is to check if the network connection is stable, try changing the network connection method, or use a more stable network environment.
  4. Router issues: Insufficient router bandwidth, signal interference, and other issues may also cause screen mirroring lag. The solution is to replace the router with a gigabit bandwidth, adjust the position of the router and the distance between signal interference sources to improve network transmission speed and stability.
  5. Device connection issues: Unstable device connections, signal interference, and other issues may also cause screen mirroring to lag. The solution is to check if the device connection is stable, try reconnecting the device, or use a stronger anti-interference cable.
  6. System issues: Operating system, driver, and application issues may also cause screen mirroring to lag. The solution is to update the operating system, drivers, and applications to fix vulnerabilities and improve performance.
  7. Other issues: There are also some other issues that may cause screen mirroring to lag, such as incorrect projector resolution settings, mismatched signal sources, etc. The solution is to check if the projector settings and signal source are correct to improve the screen projection effect.

In summary, there are many reasons for computer screen lag, which need to be investigated and dealt with according to specific circumstances. If none of the above methods can solve the problem, it is recommended to seek professional help.
