Hi, Yesterday I started using Hyperion with my rgb strip after cutting the strips the right length for my monitor and soldering them together I can use effects just fine, however when I am trying to set a solid color it just shows random colors all over the strip. Did I forget to do something because I cannot find out why this happens. Also side question do I need to solder the end of the strip to the beginning? I followed a video on YouTube and he did this but i don't understand why. Hardware: raspberry pi 2 model b ws2812b rgb strip (3,5M) 5v 8amps power adapter
