3/4 Ply is fine, at any grade. Forget NAILS. Screw into the studs, every stud, and no less than 2 inch screws. The width and height of the panel can be determined by the size of the wall space, and the TV, and the bracketing set up.

You can obviously paint the panel the color of the wall to hide any offensive appearance, though it sounds like you'll be pretty tight in spacing, then mount your bracket appropriately.

It seems that aesthetics isn't a major issue, and your cables can be gathered, hidden, in various ways.

Most of what you'll be dealing with, with a flat panel TV, is "Shear" weight"

Just my two "sense"

Not uncommon to surface mount a backing plate to hang monitors though it is cleaner looking to open the wall & fix plywood or timber blocking to the studs.

If you intend to go on the surface , 3/4''plywood would be

best to carry the weight of the TV , wallmount & cable box etc. since it will not split & takes screws well

Would make the plywood overhang the outside studs by an inch or two & the height an inch or two above & below the mounting holes of the bracket.

Would use lag screws ( or heavy duty deck screws) rather than nails to attach the plywood to the each stud in 3 or 4 places on centerlines & lag screws to hold the bracket to the plywood.

you'll need boards at least 3/4 inch thick,,,what i would do is buy 2 sheets of 3/4 plywood,,BC grade,,use 1 sheet mounted to wall,,with 2/1/2 inch dry wall screws ,,place them bout 2 feet apart in the studs,,, mount the T V bracket to this as instructions says to, make sure there is a 110 volt outlet under the T V,, and the cord is long enough to reach it,,,,,, then with 2 nd sheet,,,build some shelves under the T V,, 12 inches wide,,and bout 12 or 16 inches between the shelves,,, doing it this way it will not look like a patch job,,,but will look like a built -in cabinet,,,add trim as necessary,,prime and paint same color as trim in the room,, lightly sand between coats,,, shelves can be used for T V accessories ,,pictures,,books,, C D player,,etc,,,,

you should use at least 1x4's which measure 3/4" by 3 1/2" then use 2 1/2" screws to screw it to the studs use two screws per stud and screw into all three studs, which means the boards have to be 50 inches long. good luck. follow instuctions that came with the mounting bracket to install to the new boards. note: paint the boards to match the wall. good luck
