Have two Renegade devices one 4GB one 2GB. Neither work on my TV that uses 50FT HDMI to go from closet to TV. My previous Raspberry PI 3B worked just fine outputting to the HDMI, so I can't think that it being 50FT would be the issue but anything is possible.
Any thoughts or things I could try? Startup flags?
I'm on the latest stable release for 11.
