Thank you so much for all the feedback guys. This is all very useful information here. I am running the latest RaspberryOS and the latest Hyperion.NG
All the garbage from eBay and Amazon was counterfeit/different chipset than advertised, and ended up ultimately being my problem. The HDMI grabber I ordered from a link in this thread did the trick. Also the LEDs linked in this thread are a much much much higher quality than what I got from eBay.
With COVID stuff going on, shipping from China takes forever. So after a couple of months, I’m finally a successful Hyperion user.
tl;dr The entire time I’m watching, my mouth is hanging open in awe. Do you guys have that problem?? :omg::omg::omg::omg:
