The type of surge protector that is used at an outlet is type 3 SPD, and is marginally effective at best. You really want to stop surges before they enter your house, or at the main electrical panel, if you can. That will provide the most effective path to ground, and will prevent most of the surge from ever reaching your TV or your GDO and everything else in your house.
Your electric company may or may not allow a type 1 SPD on your meter. If they don't, then install a type 2 SPD on your main panel.
A type 3 SPD on individual devices can then handle any remaining surge that gets past the main panel.
None of these will protect you from a direct lightning strike. There's just too much power in a direct strike for them to handle.
