Troubleshooting • Subject: HDMI Output Issue on Raspberry Pi 3B+ with Retropie

Hello

I'm currently working on an Arcade1Up mod project using a Raspberry Pi 3B+ running Retropie. I'm using the original Arcade1Up monitor.
Unfortunately, I'm encountering an issue with the HDMI output, and I'm hoping someone here can help me troubleshoot.

Issue Overview:

I'm not getting any HDMI output on my Raspberry Pi 3B+ with Retropie. The monitor I'm using has previously worked successfully with an older Raspberry Pi 3B+.
The same Retropie SD card works flawlessly on other Raspberry Pi 3B+ units, and a Pi OS card works without issues on this specific Raspberry Pi 3B+.
I've copied the config.txt and commandline.txt from a working Raspberry Pi OS copy, but the problem persists.

I assume it's a confiugration setting?

This my config.txt:
# 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=0

# 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=2
hdmi_mode=16

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
hdmi_drive=1

# 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 the lirc-rpi module
#dtoverlay=lirc-rpi

# Additional overlays and parameters are documented /boot/overlays/README

disable_splash=1

# Enable audio (loads snd_bcm2835)
dtparam=audio=on
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=256
#overscan_scale=1
dtoverlay=gpio-shutdown


Thanks in advance !!
Matt
