Note that some audio links may still be present, and display or application rendering needs to be checked separately. This cannot be used to conclude that the system is completely normal.
Understand the essentials
Abnormalities may occur in application screens, remote desktops, and client video channels.
A practical example
Hypothetical example: only a certain application has a black screen, but the homepage can be displayed normally. You should also check the application compatibility or content restrictions.
What to check or try
- Return to safe homepage for observation.
- Change to a normal test application.
- Reconnect the same instance.
- Note whether it is related to landscape or image quality.
If the home page displays normally, you can limit the exception to the target application or content and provide a version and shortest recurrence. If the entire interface is not displayed, check the client video channel again. Separating these two situations can reduce unnecessary data cleaning.
An easy-to-miss detail
Do not clear application data first, exclude display links and compatibility ranges first.
