To stop a monitor shaking during gaming, first find where the movement starts: the stand, arm joint, desk clamp, desktop, desk frame, or floor. Gently press the desk and watch each part in turn. Tightening or replacing the monitor mount will not fix a desk that rocks, and a new desk arm can make movement more noticeable if the desk or clamp area flexes.
Find the source of the movement first
- Watch the floor and desk: Gently press the desktop and look for rocking at the feet, movement in the frame, or flex in the desktop. On a height-adjustable desk, observe it while using its controls.
- Watch the monitor support: If the desk stays still, check whether movement begins at the stand-to-display connection, the stand base, an arm joint, or the clamp or grommet.
- Check the cables: Make sure they have enough slack across the desk’s full height range and do not pull on the display or arm.
If the whole desk rocks, check that it sits level and that its floor contact, frame, and fasteners are secure. Address that movement before changing monitor hardware.
Fix a wobbly monitor stand
Inspect the connection between the display and stand, then the stand column and base. Tighten only the fasteners intended for those connections, following the instructions for your exact monitor. LG notes that its hand-tightened stand screws may not be fully secured and recommends a hand screwdriver or coin for its stand fasteners; do not force screws or substitute hardware by guesswork. See LG’s stand assembly guidance.

Stand designs vary. LG’s instructions distinguish screw-mounted, one-click, and clamp-mounted Ergo stands. On the described one-click design, seat the top of the stand body in the upper slot, then press the lower part until it clicks. For the described clamp-style Ergo stand, fit the clamp to the desktop thickness and tighten the handle underneath. These steps apply to those LG designs, not every monitor; consult your model’s manual. See LG’s stand installation and adjustment guide.

Stabilize a monitor arm or desk clamp
Check that the clamp or grommet is seated securely and that the arm joints and VESA fasteners are tight. If the arm uses a gas spring, set its tension according to the manufacturer’s instructions for the screen’s weight. Before installation or adjustment, confirm the desk’s thickness and strength, mount fit, and screen weight; loose fittings and joints can contribute to instability and screen shake. Fellowes covers these checks in its monitor arm installation guidance.
If the mount’s base shifts, the clamp or grommet may be insufficiently tightened, or the desk material may be compressing or slipping under load. Retighten as instructed and inspect the mounting surface. If the desk flexes or lacks structural support where the mount attaches, an adjustable reinforcement plate may help spread the clamp load; otherwise, move the mount to a stronger part of the desk or use a more suitable support surface. A plate will not correct movement elsewhere in a weak desk. See SIIG’s mount troubleshooting and clamp guidance.

Choose a mounting method that suits the desk
| Mounting option | What it changes | Trade-off to consider |
|---|---|---|
| Fixed stand | Keeps the display closer to the desktop, with less leverage than an extended desk arm. | Uses desk space, and the screen can still move if the desktop bounces. |
| Desk arm | Allows screen positioning and frees desktop space. | An extended arm can amplify movement from a flexible desk or clamp area. |
| Grommet-mounted arm | Attaches through a suitable desk hole when the mount supports that method. | Requires a suitable hole and a desk surface that can support the attachment. |
| Wall mount | Can isolate the screen from desk vibration. | Stays fixed in place, so it is less suitable if the screen needs to travel with a sit-stand desk. |
These are qualitative trade-offs, not a guarantee that a particular mounting method will eliminate movement. KTC discusses them in its monitor mounting comparison.

Before buying an arm or other mount, compare its supported range with the monitor’s weight and VESA mounting pattern. Also check desk thickness, the mount’s clamp range, clearance underneath the desk, and whether the desk material and structure can support the attachment. Consider whether the screen needs to move with a height-adjustable desk. A compatible mount still cannot cure movement caused by a rocking frame or unstable floor contact.
