I'm pretty picky about things but others notice it as well so not just me. Any idea?
You're definitely NOT being picky! Such a problem with my panel would TOTALLY RUIN my viewing experience!!
At no cost but time ................Try dis-connecting / waiting at least 15 minutes / re-connecting ALL cables AND power between the LED TV panel, one connect mini & your source player(s) / Amp.
An easy "1st" to try may be
......powering your TV temporarily from a DIFFERENT 110 volt CIRCUIT
from the "Panamax power conditioner" source cited and compare results using just one 'best' App for consistency. Be sure to pick & remain consistent using ONE picture setting; Movie / CalDay / CalNight throughout comparative 'testing'. If video behavior fluctuates between different 'circuits', then try your primary circuit's behavior WITH & WITHOUT Panamax. [BTW, it's assummed your "primary" TV power circuit is NOT overloaded with any HD 110 volt appliances like a freezer etc on say a 15 amp line.]
[BTW, dis-connection, prolonged shut-downs \ reboots ....while retaining all existing cables
...will sometimes ""cure"" mysterious glitches. Such has been the case for me & others.]
Let us know the result(s) of your systematic sleuthing.
