Vizio E390 A1 Settings
I have the same TV .Here are my settings Give them a try...
Picture Mode: Vivid (Don't adjust anything)
Color Temp:Cool (No adjustments)
Under advanced picture:
Noise reduction :High
Mpeg: High (for pictures)
Adaptive Luma :Strong
Film Mode :Auto
Backlight control : OPC (Optimal contrast)
Ambient light sensor :OFF!! This option will dim you picture if turned on..
I have found that these settings gave me the best picture after tooling around with quite a few times.
I hope this helps.....
