the one response you did get pretty much covered it:
"There's always some quick screen adjustment period while it searches / adapts to the signal presence or absence. What matters is what it does when it finds it ."
Almost all tvs these days do some weird things during boot-up or when changing signal sources etc. Some even lose HDMI handshake while the menu loads on a BD. As long as these anomalies don't get any worse or start to show up in the middle of normal viewing there just isn't enough to worry about to spend the time trying to find out the specific cause. If a split second of green halo only at initial startup is a deal breaker, return the set.
If you'd bought a Sony HX929 you'd have found that you couldn't access the menu for as much as 30-45 seconds after a picture appeared on the screen, it takes that long for them to fully boot-up.
