I thought I'd reinvigorate this thread a bit. I've also been experiencing ghosting with the Indivision ECS V2, and although it can be considered "tolerable", I expected better. This is the only iComp product I'm not completely happy with, and my A500 is pretty stacked with iComp products (ACA500plus, ACA1221lc, ACE2, A512, RTC module, CA-PSU).
I tried pretty much all fixes suggested in this thread (thanks everybody), without any noticeable improvement. I'd be in the market for the mentioned hardware mod.
