Troubleshooting HDMI Output on BeagleBone Black: No Signal Issue
Hello guys, I'm developing a digital signage project using the BeagleBone Black (BBB) running a custom Embedded Linux image. The project requires displaying dynamic content on an HDMI monitor. However, the HDMI display is not working, and I am unable to get any output on the screen. I did configure the HDMI output by ensuring that the BBB is set to output in the HDMI port 
sudo nano /boot/uEnv.txt
sudo nano /boot/uEnv.txt
In uEnv.txt, I ensured that the needed lines are uncommented or added 
optargs="video=HDMI-A-1:1024x768@60e"
optargs="video=HDMI-A-1:1024x768@60e"
I then reboot the system 
sudo reboot
sudo reboot
After rebooting, the HDMI monitor still shows no signal, and the screen remains blank.
