Pay attention to this tv mine came from vizio itself and the top center 1/6th of the screen greys out when there is a temporary popup on the screen. This area is black so colors being grey makes it look washed out every time!
If this happens to you, i would send the tv back!!!
Vizio are you giving an update to fix this problem? If so, email me at firstname.lastname@example.org to let me know! thanks!
