Hi all, Lost Beginner here. So below is my setup: - RPI3B - Adafruit RGB Matrix HAT + RTC - P2.5-2121-128x64-32S LED Panel (using IC SM16380) when i run the ./demo -D 0 and regardless of what Options i’d used, I’m just seeing lines on the LED Screen. [![Imgur](https://global.discourse-cdn.com/free1/uploads/rpi_rgb_led_matrix/original/1X/7947da81bf669d6d1275ded16b7af58de5a5e7d5.jpeg "imgur.com") ](https://imgur.com/0BweMO6) I’m kinda lost in how should i troubleshoot this. Can I get some guidance/help from the gurus? Thank You. ---

Hi there, Thanks for the update. Looks like I’d need to reinvest in older model Boards.
