Advanced Solutions for Persistent USB-C to HDMI Problems
If you’re still having trouble with your Samsung USB-C to HDMI connection, it’s time to try more advanced fixes. Sometimes, the issue is in the device’s settings or software.
Force Alternative Display Modes on Samsung Devices
One solution is to force alternative display modes on your Samsung device. This can fix issues with certain HDMI displays. To do this, go to your device’s settings, then to “Developer options.” Look for “Force full screen activities to be resizable” or similar options.
Clear Cache and Reset App Preferences
Clearing the cache and resetting app preferences can also help. This removes any corrupted data that might be causing problems.
To clear cache, go to “Settings” > “Storage” > “Cached data,” and then confirm the action. Resetting app preferences can be done by going to “Settings” > “Apps” > “Menu” (three dots) > “Reset app preferences.”
Disable Battery Optimization for Display Services
Battery optimization can sometimes cause issues with display services. Disabling this optimization for display services can help maintain a stable connection.
To do this, go to “Settings” > “Battery” > “Battery optimization,” and then find the relevant services to disable optimization.
Test in Safe Mode to Identify Third-Party App Interference
Booting your Samsung device in safe mode can help find if a third-party app is causing the problem. In safe mode, all third-party apps are disabled. If the connection works in safe mode, it means a third-party app is likely the cause.
Factory Reset Considerations and Procedure
As a last resort, a factory reset can solve deep-seated software issues. But, this will erase all data on your device. So, it’s crucial to back up your important files and data before proceeding.
To factory reset your Samsung device, go to “Settings” > “General management” > “Reset” > “Factory data reset,” and then follow the prompts.
