May I know which error are you facing when you want to change the screen resolution?
Are you able to change the screen to the recommended one?
To troubleshoot this issue, kindly do the steps below:
1-Go to Start > Settings > System > Display > Scroll down to Display Resolution and change it to the Recommended one.
2-Check for updates:
Start > Settings > Update and Security > Check for update.
3-Try to Update the graphics card driver:
Press Win + X > Device Manager > Navigate to your graphics card driver > Update it.
4-If the issue persists, instead of updating, uninstall it, download the latest driver from the manufacturer's website, and re-install it.
Please let me know if you need further assistance and keep me updated.
