Good catch! This is certainly multi-system not one pc stretched across multiple monitors. I tried some more troubleshooting following @Frank suggestions and I'm still where @mmerelles is. At best, 20% chance of a decent sync. In part the blame is on LR for forcing us down the multi PC path. Lots of 3rd party aircraft have systems sync issues too (777, x737, etc) Support for SLI and mutli-monitors (on one system) would really really help!!!
