Flicking Screen #109

Before filing a bug report

Replicate your issue on Raspbian Lite Raspbian Lite is the preferred target OS for this system. I will not address bugs that can only be replicated on 'nix with a graphical user interface.

Ensure your operating system is up-to-date ...and that you can replicate the problem with an up-to-date (and rebooted) system. To ensure all is update, run the following in a terminal, sudo apt-get update && sudo apt-get dist-upgrade -y && sudo apt-get auto-remove -y && sudo apt-get autoclean

If you do the above two things and can still replicate the issue, then...

Describe the bug Running Rasbian Lite on a Raspberry Pi4 Displaying 6 800x600 cameras

Seems to lose HDMI sink with the monitor and the whole thing flickers black running at 1980x1024 @60Hz on a large TV

To Reproduce Steps to reproduce the behavior:

  1. Install per README.md
  2. Configure my feeds in layout.conf.default
  3. Run 'sudo displaycameras start'
  4. screen flickers

Raspberry Pi (please complete the following information):

Suggest running just one stream according to debug instructions late in the README.md. If flickering is present in that debug playback, the problem is in your display or cabling or RPi.

Thanks

Hi thanks for the response. After about an hour of fiddling with Config.txt settings.. Turning the HDMI_boost on and off (up and down). I manage to solve the problem by activating the HDMI_1 output and moving the cable there and rebooting.. I think this is either a hardware issue or a bad cable.

For some reason when I add the 5th camera to off screen, my screen just flickers like no other and cameras start overlapping. Any idea why? Sorry for being a noob
