Update: Everything seems to stay fine as long as I leave everything at 100% (dimmer/button LED's). Even if I change the dimmer to a lower setting it freaks out and goes back to where it was. Shouldn't be a problem, i'll just leave it at 100% for now.. But it would be nice to figure out why it does this.

Keep in mind this is only w/ the display extender. I tried grounding the display, no luck. Could it be some sort of signal latency? I wouldn't think so considering the dimmer chip is on the display board itself, and the extension is only about 7".
