1. I understand that you can't see video output now and you want boot in SAFE mode in order to set 60Hz refresh rate back?
2.  Boot from your Windows 10 installation USB. The Installation Media USB (if you don't have one), you may prepare using Microsoft Media Creation Tool
3. Select your language preferences and click/tap on Next.
4. Click/tap on Repair your computer at the bottom.
5.  Click/tap on Troubleshoot.
6. Click/tap on Advanced options.
7.  Click on Command Prompt
8. In the Command Prompt write the following command: bcdedit /set {default} safeboot minimal and press enter to execute this command
9. Close the Command Prompt window by clicking the X in the upper right corner of the Command Prompt window.
10.  Select Continue and sign in to Windows 
11. While in Windows, press Windows key + r. Run msconfig
12. Chose Boot tab and uncheck Safe boot. Reboot your system.
