Asuming you have Low Resolution display 1366x768, give this bootpack a try.
First download this, then add the attached into /EFI/Clover
I didn't include Apple or Microsoft folder, those should be there when you first install Clover, but don't delete them
Just add the contents of EFI replacing the files
If your resolution is higher, let me know
