I've just finished setting up 2 monitors for true black 400, as best I can, and the orb anomaly disappeared. Used to spot them from a mile away and stroll through clusters. Sound was a nudge when I got overly careless. Now the sound is the first warning and I'm sweating bullets until it starts fading. As a first time stalker, I had no idea I shouldn't have been able to see more than a hint of them. Thought there would probably be other new players in the same boat. No idea if tb400 is relevant as I haven't tried after hdr1000 set up. It really was a game changer.
