TV mount is 16.5" wide but stud centers are 17" apart. Is it still safe to mount?
Last time I encountered that, I put two 2x4's across the stud span, chamfered the edges too a 45 angle and painted it to match the wall. Mounted the bracket onto that, if it's a rental or you just don't want to wreck the walls, put a thin piece of cardboard between the 2x4 and wall before you mount it to make sure it doesn't pull up any paint when you remove it. You might be able to get away with one on stud one with anchor, but if it fails......
