Hello all, I am using Raspian that comes with Noobs.
I want the monitor full screen, read the instructions, unquoted the lines required and tried to save. The save changes to 'config.txt'? appears, I press yes. I select the config.txt from the list and press save. I get the message that 'config.txt' already exists Overwrite?. I select yes then the error message pops up and says, Can't open file to write. How do I save changes to this file please?
