How can I fix the subtle pattern I'm seeing on white backgrounds on my TV?

Episode 1328 (1:06:52)

Lori from Napa Valley, CA
Vizio TV

Lori has a budget Vizio TV and she sees a subtle diagonal pattern when there's a bright background. It's distracting. Scott says to go into the menu and look under 16:9 to see if overscanning is enabled. Overscanning can cause scaling and artifacting, too. Scott doesn't see any way to turn that off, so she may want to contact Vizio about it.
