Can these mounts hold a 75-inch or larger TV?

Several picks are rated to 90 inches and 132–150 lbs, which covers most 75"+ panels. However, r/GeekSquad and r/hometheater commenters caution that on very large screens a full-motion arm gives you less usable swivel and more visible sag at full extension, so heavier buyers often prefer an advanced tilt or fixed mount over a long articulating arm.
