    How to change retroarch.cfg resolution and ratio?

    what is the line? the screen is below the bottom of the screen by several pixels and its ratio is 1:1 and not 4:3

    thanks for your help


    I think you need to add this line to retroarch.cfg:

    video_aspect_ratio_auto = false

    According to the retroarch.cfg config file:

    If this is true and video_aspect_ratio is not set,
    aspect ratio is decided by libretro implementation.
    If this is false, 1:1 PAR will always be assumed if video_aspect_ratio is not set.

    Here is the rest of the config options for retroarch.cfg for reference:


    how would I force a 4:3?

    video_aspect_ratio = 4:3


    The person in this thread: https://www.petrockblock.com/forums/topic/force-43-screen/ said setting video_aspect_ratio = 1.175 gave good results. Or you can change it in the emulator (if it’s a Retroarch core) by accessing the GUI, think it’s f1 if you’re using a keyboard or you can map it to your gamepad/joystick in retroarch.cfg with:

    input_enable_hotkey_btn = "**" 
    input_menu_toggle_btn = "**"

    (the stars are where you specify the buttons on your controller)


    I just wanted to share settings for others, an easy searchable post with ratios

    video_aspect_ratio = 
    #1.333333 (4:3) Traditional SDTV
    #1.56 (14:9) 4:3/16:9 Compromise aspect ratio
    #1.6667 (5:3 Super 16mm)
    #1.77 (16:9) HDTV US standard 
    #1.78 (16:9) HDTV US standard alternate
    #1.6 (16:10) Common computer screen ratio
    #1.6667 (5:3) Common European widescreen standard
    #1.85 Common US widescreen cinema
    #2.39 Current widescreen cinema alternate
    #2.40 Current widescreen cinema alternate
