Interior wall for mounting tv - nails vs screws

Hi everyone
I am building an interior wall to hold a 40" tv, which combined with the weight of the mount itself, we're looking at approx. 80lbs.

In framing the wall, should I be using nails or screws in it's construction?

In reading a few other posts, someone else recommended putting sheets of plywood under the drywall on the side that the TV will be mounted on for additional support...can anyone also weigh in on that suggestion? If this is a good idea, would i be going with 1/4" or 1/2" ply? 1/2" seems a little excessive to me but I'm sure someone here would have much better insight.

Any advice or tips would be greatly appreciated.
Thanks everyone.

Anytime you frame you Should use nails but if you want to screw them you should use a 3" deck type screw. NOT a Sheetrock type screw. Instead of plywood I would block where the tv is going so that you can screw in anywhere you need to. Make sure you secure the top and bottom well

I agrees with robs660. I don't see how plywood is going to help much, and you would have to do the entire wall so the drywall will be even.

You want your mount to go into studs/blocking, not plywood, so the cross-blocking is a good idea, especially if you can figure out the level where you will be placing the mount. In fact, since it is only for the TV, you can mount the blocking so the broad face of the lumber is against the drywall, as that will be stronger in a vertical direction and has the added advantage of giving a larger surface to fasten the mount.

80 pounds is not all that much. A large mirror will weigh that much, and people mount those on walls every day.

Heck, they sell picture hangers that hold 100 pounds in drywall alone.
