Glare is conditional
If the TV would face Lake Ray Hubbard, take the photo at the hour you watch. Bright water can erase the picture even when the mount is perfect. A different wall, shades, or a modest change of angle may beat a moving bracket. If the moving bracket is still what you want, show the side clearance so it does not hit a window frame or a cabinet. Inland Rockwall rooms should skip this and talk about the fireplace instead. Stone and drywall are both possible. Show the one you have.
