    I’m having a minor problem with the video output, it’s a few pixels too far to the left and the leftmost pixels are obscured, if that makes sense. It’s not a huge problem but in the command line bit it’s a problem, especially with the controller configuration. Is there a way to fix this or is it my television at fault?

    It’s a Raspberry Pi 2 running the most recent Retro Pie version and it’s composite output

    Oh man, have you got an actual CRT?

    Anyways yeah, to add to what Floob has said, I believe you need to alter the various overscan values in /boot/config.txt

    overscan_left	number of pixels to skip on left
    
    overscan_right	number of pixels to skip on right
    
    overscan_top	number of pixels to skip on top
    
    overscan_bottom	number of pixels to skip on bottom

    Tweak the values until the video output fits comfortably inside your display.

    We’ve got a couple of CRTs, they still work fine and we see no reason to be rid of them, they’re late 80s/early 90s though so they don’t have all the fancy knobs the old ones have.

    And yeah, doing the overscan left to 32 pixels worked perfectly, it looks just fine now.
