I can wall mount just about any LCD, Plasma or OLED TV. The main thing to keep in mind is that TVs are heavy and must be mounted to the wooden studs in your walls with long and sturdy screws to be secure. I don’t recommend mounting large TVs over 50 lbs to the metal studs used in modern construction. Be sure to get the right mount for your TV or if you arrange it ahead of time I can supply one.
A popular place to mount TVs is above the fireplace. Before doing this it is important to make sure there are at least 2 solid studs back there. This is obviously not a load bearing wall so it may not have the proper studs. Before deciding to mount a TV above the fireplace it might be worth investing in a stud finder or drilling a few small test holes to be sure it has the proper studs.
