Full-motion arms in rooms that look at Lake Ray Hubbard
Rowlett rooms that face the water have a glare problem no picture setting fully solves, and that is the most common reason a homeowner here asks for a full-motion arm instead of a flat bracket. An articulating mount changes the load math. A 75-inch panel at full extension puts a long lever on the wall, so a single stud is not enough: your installer uses a plate that spans two studs with four 1/4-inch lag bolts seated 2.5 inches deep, and on plaster-free drywall walls that is the whole strength of the install. The arm gets swept through its full travel before the TV goes on, checking that it clears window trim, a door casing and any lamp on the console. Cable is run with a service loop long enough for the full extension, because a taut HDMI at the end of the arm is what eventually fails. The full-motion add-on is $59-$79 on top of the size-based rate. Expect 70 to 95 minutes for the arm, the plate and the sweep test.
