      Hello, I tried searching for this but I simply cannot find it. I know I found the answer to this before somehow, but where would I find the latest default boot config.txt file? In case I mess something up?

        Depends on your Pi model. Just back it up before you make edits? If you've already messed it up, you can use 7zip on a PC to view the contents of the official install image for your model of Pi and copy the file out of that.

          @greenhawk84 Download the latest image and open it with 7zip to look in the boot partition and read it. This is what it looks like, extracted from the PI4 image:

          # For more options and information see
          # http://rpf.io/configtxt
          # Some settings may impact device functionality. See link above for details
          
          # uncomment if you get no picture on HDMI for a default "safe" mode
          #hdmi_safe=1
          
          # uncomment this if your display has a black border of unused pixels visible
          # and your display can output without overscan
          #disable_overscan=1
          
          # uncomment the following to adjust overscan. Use positive numbers if console
          # goes off screen, and negative if there is too much border
          #overscan_left=16
          #overscan_right=16
          #overscan_top=16
          #overscan_bottom=16
          
          # uncomment to force a console size. By default it will be display's size minus
          # overscan.
          #framebuffer_width=1280
          #framebuffer_height=720
          
          # uncomment if hdmi display is not detected and composite is being output
          #hdmi_force_hotplug=1
          
          # uncomment to force a specific HDMI mode (this will force VGA)
          #hdmi_group=1
          #hdmi_mode=1
          
          # uncomment to force a HDMI mode rather than DVI. This can make audio work in
          # DMT (computer monitor) modes
          #hdmi_drive=2
          
          # uncomment to increase signal to HDMI, if you have interference, blanking, or
          # no display
          #config_hdmi_boost=4
          
          # uncomment for composite PAL
          #sdtv_mode=2
          
          #uncomment to overclock the arm. 700 MHz is the default.
          #arm_freq=800
          
          # Uncomment some or all of these to enable the optional hardware interfaces
          #dtparam=i2c_arm=on
          #dtparam=i2s=on
          #dtparam=spi=on
          
          # Uncomment this to enable infrared communication.
          #dtoverlay=gpio-ir,gpio_pin=17
          #dtoverlay=gpio-ir-tx,gpio_pin=18
          
          # Additional overlays and parameters are documented /boot/overlays/README
          
          # Enable audio (loads snd_bcm2835)
          dtparam=audio=on
          
          [pi4]
          # Enable DRM VC4 V3D driver on top of the dispmanx display stack
          dtoverlay=vc4-fkms-v3d
          max_framebuffers=2
          
          [all]
          #dtoverlay=vc4-fkms-v3d
          overscan_scale=1
          

          For the PI2/3 models, I think there's a memory setting added that's extra, the rest should be identical.
