      A config.txt file I've used in the past that worked perfectly is now not working at all.

      The most annoying part is that my Pi 4 was booting just fine but then I went to change some display settings to remove the black borders and now my Pi 4 won't boot into emulation station at all. It just ends up on a "no signal" screen after the boot up terminal.

      I've had troubles with my Pi in the past and I've been able to solve the solution by looking up my problem online but I feel like I've hit a dead end here.

      Any help would be much appreciated.

      This is the config.txt I've used.

      overscan_left=10
      overscan_right=-18
      overscan_top=-14
      overscan_bottom=-7

      hdmi_ignore_edid=0xa5000080

      hdmi_force_hotplug=1

      hdmi_group=1
      hdmi_mode=20

      hdmi_drive=2

      config_hdmi_boost=7

      dtparam=audio=on

      dtoverlay=vc4-fkms-v3d
      max_framebuffers=2

      gpu_mem=320

        This should probably be left on default but in any case the maximum value is 256.

        https://retropie.org.uk/docs/Pi4/#memory-split

        https://retropie.org.uk/docs/Memory-Split/#raspberry-pi-4

        https://www.raspberrypi.com/documentation/computers/config_txt.html#gpu_mem

        I don't know if that would prevent boot though, or just fallback to a supported value such as the default 76 or maximum 256.

        Besides that I'm not sure. I suppose all the hdmi_ settings are necessary because you use a non-standard display/monitor that does not work without them?

          To add upon @sleve_mcdichael:

          1st.: Please provide some more Info (as mentioned here).

          Then how (th) did you came up with that config.txt? As you mentioned, you only wanted to get rid of the black borders and for that AFAIK the only option you most propably need is disable-overscan, if that is expanding the screen beyond its borders or is still coming with black-border(s) the overscan offsets are the only parameter that (again IIRC) are needed - the no signal most propably is just due to the fact that your display ain't supporting the output your raspi is sending to it due to that config.txt (hdmi_mode 20, or even hdmi_group 1 not supported? Some of the other options adding up to it? As said, too less information offered on your behalf).

          Edit: By the way... hdmi_boost is ignored on the Pi4. It is never a good idea to blindly copy&paste without rtfm'ng the basics.

            Replace the current config.txt with a fresh one and try again:

            # 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

            My English isn't at a good level.

              Thanks for the suggestions you three. I appreciate the help.

              I managed to solve my problem by writing Retropie on my Pi 4 SD card again. I then plugged my Pi 4 back into the TV that wasn't working after enabling the settings I'll mention below, It still came up with no signal after boot up so I used another TV around the house and after my Pi 4 did the first boot up in the terminal and loaded into emulation station on the old TV, I plugged my Pi 4 back into the new TV and it works like nothing happened? If anyone knows how the hell that worked please let me know.

              It has black borders and I'm going to attempt to fix that, lets hope I don't break anything again xD

                  I'm sorry, I was very tired and frustrated at the time.

                  I used hdmi_boost to allow my TV to show display at one point and it worked I'm pretty sure. I don't need it now for some unknown reason.
