I am using a 16x32 RGB led matrix by Adafruit. When I tested it at my desk with short 6 inch jumper wires it worked just as I wanted. However, for my actual project the screen cannot by right next to the pi itself so I got 50cm jumper wires. When I tried extending the wires the display did not show correctly. Pixels not in the code started lighting up and areas of the screen flickered. What is causing this and is there a physical solution (or software) that would solve this? Thanks!
