TV Not Level After Mounting? Troubleshooting Guide
Is your mounted TV crooked or not sitting level? Learn the common causes, DIY adjustment techniques, bracket re-leveling steps, and when it is time to call a professional.
Common Causes of an Unlevel Mounted TV
A crooked TV after mounting is one of the most common and frustrating issues homeowners face. There are several reasons why a TV may not sit perfectly level even after a careful installation. The most frequent cause is that the wall plate of the mount was not leveled precisely during installation. Even a small deviation of one or two degrees at the wall plate translates into a visible tilt when the TV is hanging several feet wide. A 65-inch TV that is off-level by just one degree will show a gap difference of about half an inch between the left and right sides, which is noticeable to most people. Uneven wall surfaces are another common culprit. Drywall can have subtle curves, bumps, or depressions caused by settling, moisture damage, or imperfect installation of the drywall itself. When a mount plate is bolted flat against an uneven wall, the plate conforms to the wall surface rather than hanging truly level. Additionally, some mounts have manufacturing tolerances that allow slight play in the connection between the wall plate and the TV brackets, which can cause the TV to hang at a slight angle even when the wall plate is level.
Checking and Adjusting the Wall Plate Level
The first step in troubleshooting a crooked TV is to check whether the wall plate is level. Remove the TV from the mount, which usually requires lifting it off the mounting hooks or loosening retention screws depending on your mount design. With the TV removed, place a level across the top edge of the wall plate. A long level of at least 24 inches provides better accuracy than a short torpedo level. If the wall plate is not level, you have two options depending on the mount design. Some mounts have slotted holes in the wall plate that allow you to loosen the mounting screws slightly, adjust the plate position, and retighten. This is the easiest fix because it does not require removing the plate from the wall or drilling new holes. Simply loosen each lag bolt or screw by one or two turns, tap the plate gently in the direction needed to level it, verify with the level, and tighten the screws firmly. If your mount uses round holes rather than slotted holes, or if the plate is significantly off-level, you may need to remove the plate entirely, fill the old screw holes with wooden dowels and wood glue, and reinstall the plate at the correct position. This is more involved but ensures a precise result.
Using Built-In Leveling Adjustments
Many modern TV mounts include built-in post-installation leveling adjustments that allow you to fine-tune the TV position without removing it from the wall. These adjustment mechanisms vary by manufacturer but typically fall into three categories. Hook-style adjustments use a set screw on one or both of the TV hooks that raise or lower that side of the TV relative to the wall plate. Turning the screw clockwise raises the hook, lifting that side of the TV. This is the most common adjustment type and can correct tilts of up to two or three degrees, which is sufficient for most situations. Bracket arm adjustments are found on articulating and full-motion mounts. These adjustable arms allow you to loosen a set screw or bolt at the pivot point and manually tilt the TV until level, then retighten. This adjustment is particularly useful because it corrects the level of the TV independent of the wall plate, meaning even if the wall plate has a slight tilt due to wall imperfections, you can compensate at the bracket arm level. Some premium mounts feature micro-adjustment systems with a dial or knob that provides precise, tool-free leveling with the TV in place. These systems allow adjustments as small as a fraction of a degree and are the easiest to use because you can see the result in real-time as you turn the adjustment mechanism.
Dealing with Uneven Wall Surfaces
If the wall plate reads level but the TV still appears crooked, the wall surface itself may be the problem. Old homes, walls that have experienced settling, and drywall over imperfect framing can all create surfaces that are not truly flat. To test for this, hold a long straightedge or level against the wall horizontally where the mount plate will attach. Look for gaps between the straightedge and the wall surface, which indicate high or low spots. Thin shims placed behind the mount plate can compensate for wall irregularities. Use metal or hard plastic shims rather than wood, as wood shims can compress over time and allow the mount to shift. Place shims at each mounting screw location as needed to create a level plane for the mount plate, then tighten the screws to compress the shims against the wall. For severe wall irregularities, a piece of three-quarter-inch plywood cut slightly larger than the mount plate and fastened to the studs creates a flat, level mounting surface. This approach is common in our basement home theater installations where concrete walls often have surface irregularities. The plywood can be painted to match the wall or will be hidden behind the TV.
When the TV Itself Causes the Tilt
In some cases, the issue is not with the mount or wall but with how the TV attaches to the mounting brackets. Modern TVs do not always have perfectly centered or perfectly symmetrical VESA mounting holes on their back panels. Manufacturing tolerances in the TV frame itself can result in the screen appearing slightly tilted even when the mounting brackets are perfectly level. Check that all four VESA bolts connecting the TV to the brackets are fully tightened. A loose bolt on one side allows the TV to sag on that corner, creating a visible tilt. Use the correct bolt length specified for your TV model. Bolts that are too long will bottom out before they are tight, and bolts that are too short may not engage enough threads for a secure hold. Spacers included with many mount kits are essential for TVs with curved back panels or recessed mounting holes. If spacers are required but missing, the brackets may not sit flush against the TV back, leading to uneven mounting. Verify that you are using all the hardware pieces included with your mount and that each bracket is pulled snugly against the TV surface.
When to Call a Professional
While many leveling issues can be resolved with the adjustment techniques described above, some situations benefit from professional intervention. If you have tightened all adjustments and the TV is still noticeably off-level, the problem may be structural. Walls in older homes, particularly those in historic neighborhoods, can have studs that are not plumb, meaning they lean to one side. Mounting to these studs pulls the bracket in the direction of the lean, and no amount of surface adjustment can fully compensate. A professional installer can identify structural issues and implement solutions such as blocking between studs or using a mounting board to create a true vertical mounting surface. If your mount screws have stripped the wood studs or pulled through the drywall, attempting further adjustments can make the situation worse. Stripped stud holes require proper repair with epoxy-filled dowels or relocation to fresh stud material, which is best handled by an experienced technician. For TVs over 65 inches or installations using full-motion mounts, the weight and leverage involved make adjustment more challenging and the consequences of an insecure mount more severe. Technicians carry professional-grade leveling tools, a full assortment of shims and hardware, and have the experience to diagnose and fix leveling issues efficiently, usually in a single visit.
Frequently Asked Questions
Why is my TV tilted after mounting?
The most common causes are an unlevel wall plate, uneven wall surfaces, loose VESA bolts connecting the TV to the brackets, or manufacturing tolerances in the TV itself. Check the wall plate with a level, tighten all connections, and use the mount built-in leveling adjustments to correct the tilt.
How do I level my TV mount without removing it?
Many mounts have built-in leveling adjustments such as hook-height set screws or pivot point adjustments. Look for Allen key or Phillips-head set screws on the TV hooks or bracket arms. Loosening these allows you to raise or lower one side of the TV until it sits level, then retighten.
Can an uneven wall cause a crooked TV?
Yes, walls that are not perfectly flat cause the mount plate to conform to the wall surface rather than sitting truly level. This is common in older homes and basement installations. Shims placed behind the mount plate at each screw point can correct the issue.
What if my TV mount screws are stripped?
Stripped screw holes in wall studs require repair before the mount can be re-secured. The standard fix is to remove the mount, drill out the stripped hole, insert a glued wooden dowel, let it cure, and then re-drill and remount. This restores the full holding strength of the connection.
Is it normal for a mounted TV to be slightly off-level?
A very slight deviation of less than half a degree is common and usually not noticeable. If the tilt is visible when viewing the TV from your normal seating position, it should be corrected. Most quality mounts include adjustment mechanisms that can correct tilts of one to three degrees without removing the mount.
