[i'm stuck at the exit of hoenn's abandoned boat]

I went to the abandoned boat, I did the captain's quest, took the scanner in short, everything was fine until I got out of the boat when I get out I am stuck and my only option is to go back inside because of the fact that i can't use surfing.

 

Help me please

[I can't reset my base resolution]

Hello my game was previously 1680x1050, but since I inadvertently changed the resolution I can't go back to that resolution anymore and I'm stuck in 1280x1024, would you know how I could go back to the previous resolution?
