10 Common TV Mounting Mistakes and How to Avoid Them
Learn the 10 most common TV mounting mistakes homeowners make and how to avoid them. From incorrect height to missing wall studs, this guide helps you get it right the first time.
Why TV Mounting Mistakes Are So Common
TV mounting looks simple in concept but involves more precision and technical knowledge than most homeowners expect. A survey of professional installers found that over 60 percent of service calls to fix mounting issues involve correcting DIY mistakes. These errors range from minor aesthetic problems like a slightly crooked mount to serious safety hazards like a TV anchored only to drywall without stud support. The good news is that every common mistake is completely avoidable with the right knowledge and preparation. Whether you plan to tackle the project yourself or hire a professional TV mounting service, understanding these pitfalls helps you achieve a perfect result and protect your investment.
Mistake 1: Mounting Too High on the Wall
The single most common TV mounting mistake is placing the TV too high. Many homeowners default to mounting the TV above the fireplace or at a height that looks good from a standing position, only to discover that watching from the couch requires them to crane their neck upward. The ideal TV position places the center of the screen at seated eye level, which is typically 42 to 48 inches from the floor for a living room and slightly higher for a bedroom. If you must mount above a fireplace, invest in a pull-down or tilting mount that brings the screen closer to eye level during viewing. Measure from your normal seated position before committing to a height.
Mistake 2: Not Finding Wall Studs Properly
Anchoring a TV mount to drywall alone is a recipe for disaster. Drywall anchors, even heavy-duty toggle bolts, are not designed to support the dynamic load of a mounted TV over time. A 65-inch TV with a full-motion mount can exert over 100 pounds of force on the wall when fully extended. This load must be transferred to wall studs, which are the vertical wooden framing members behind the drywall. Use a quality stud finder to locate studs and verify their position by driving a small nail into the wall at the marked location. Many inexpensive stud finders give false readings near electrical wires or plumbing, so always confirm with a physical check. Your mount should be secured into at least two studs with lag bolts for maximum safety.
Mistake 3: Choosing the Wrong Mount Type
Not all TV mounts are created equal, and choosing the wrong type for your situation leads to a suboptimal experience. Fixed mounts are the most affordable and hold the TV flat against the wall, but they offer no adjustability. Tilt mounts allow you to angle the screen downward, making them ideal for above-fireplace or bedroom installations where the TV is above eye level. Full-motion articulating mounts extend from the wall and swivel left, right, up, and down, providing maximum flexibility for corner installations or rooms where you watch from multiple seating areas. The mistake is choosing a fixed mount when a tilt or full-motion mount is needed, or selecting a mount that does not support your TV's weight and VESA pattern. Always check the mount's weight capacity and VESA compatibility before purchasing.
Mistake 4: Ignoring Cable Management
A beautifully mounted TV with a tangle of cables hanging below it defeats the purpose of a clean wall-mounted installation. Yet many homeowners focus entirely on getting the TV on the wall and leave cable management as an afterthought. Plan your cord concealment strategy before you start drilling. Options include in-wall cable routing for the cleanest look, external cord covers that can be painted to match your wall, and cable raceways that attach to the baseboard. For in-wall installations, you will need a low-voltage bracket behind the TV and another near your power source. Running power cables inside the wall requires either a code-compliant power relocation kit or a new outlet installed by a licensed electrician.

Mistake 5: Not Checking for Obstructions and Using Wrong Hardware
Before drilling into any wall, check for electrical wires, plumbing pipes, and HVAC ducts that may run behind the drywall. Drilling into a live electrical wire creates a serious electrocution and fire hazard. Hitting a water pipe causes immediate and expensive water damage. Use a stud finder with wire detection capability and inspect the wall area carefully before drilling. Check both sides of the wall if possible. Mistake number six is using the wrong hardware. Generic wood screws, nails, or undersized bolts cannot safely support a TV mount. Professional installations use lag bolts, typically 3 to 4 inches long with a 5/16 inch diameter, driven directly into wall studs. For concrete or brick walls, tapcon screws or sleeve anchors rated for the full weight of the TV and mount assembly are required. Never substitute hardware that is not specifically designed for the load.
Mistake 7: Poor Leveling and Forgetting About Viewing Angle
A TV mount that is even one or two degrees off level is immediately noticeable once the TV is hung and turned on. The horizon line in any landscape shot or the edge of a news ticker will appear slanted, creating a constant visual distraction. Always use a bubble level or laser level when positioning the bracket, and verify level again after tightening all bolts. Many mounts have post-installation adjustment screws that allow fine-tuning of the level after the TV is attached. The eighth common mistake is failing to consider viewing angle. If your couch is off to the side rather than directly in front of the TV, a fixed or tilt mount will result in a poor viewing angle with washed-out colors and reduced contrast. Full-motion mounts solve this problem by allowing you to angle the TV toward your primary seating position.
Mistakes 9 and 10: Skipping Planning and Doing It Alone
Mistake nine is failing to plan for future changes. If you might upgrade to a larger TV, consider mounting the bracket at a height and position that accommodates a bigger screen. If you plan to add a soundbar later, leave adequate space below the TV and consider running an extra HDMI cable through the wall while it is already open. Planning ahead saves the cost and hassle of a second installation. The tenth and final mistake is attempting to mount a large TV alone. TVs 55 inches and larger are unwieldy and difficult to lift, align, and attach to a wall bracket safely by yourself. The risk of dropping the TV, injuring yourself, or mounting it crooked increases dramatically when working alone. Either recruit a helper or hire a professional TV installation service to ensure the job is done safely and correctly. Get an exact price instantly with our online quote tool.
Frequently Asked Questions
What is the most common TV mounting mistake?
Mounting the TV too high is the single most common mistake. The center of the screen should be at seated eye level, typically 42 to 48 inches from the floor, not at standing eye level or above a fireplace without an adjustable mount.
Can I mount a TV without hitting a stud?
It is not recommended. Drywall alone cannot safely support the weight of a TV and mount over time. If studs are not available at your desired location, use a mounting plate that spans multiple studs, or consult a professional about concrete anchors or alternative solutions.
How do I know if my TV mount is level?
Use a bubble level or laser level when positioning the bracket before tightening the bolts. After hanging the TV, check level again and use the mount's built-in adjustment screws to fine-tune if needed.
What happens if I drill into a wire in the wall?
Drilling into a live electrical wire can cause electrocution, electrical shorts, or a fire. Always use a stud finder with wire detection capability and turn off power to nearby circuits before drilling. If you are unsure, consult a professional.
