2x 64x64 adafruit panels

Hi. I have two 64x64 adafruit panels. (64x64 RGB LED Matrix - 2.5mm Pitch [1/32 Scan] : ID 3649 : $54.95 : Adafruit Industries, Unique & fun DIY electronics and kits). These ones to be exact I am completely lost with them. I was wondering if someone could help me. I want to mirror the HDMI from my raspberry pi using rasping with the desktop. I have tried following the tutorial on aduidfruits website and the image looked terrible and you can not see anything on it. From a Fresh install can Somme please help me. id hate to let these go to waste I have tried multiple times over and over again.

Thanks James
