Nice build. I also like the marque with the white border. I’m building a cabinet very similar to yours. I’ll post pics in 2-3 weeks when I’m finished. I’m using a Vizio tv for my cabinet and I believe I’m having the same timing issue. When they are both off and I turn everything on at once then the video never shows up. I have to reboot the pi in order for it to work. I’m a newbie so could you explain what you did exactly with the config.txt file?
