How to Adjust Monitor Stand | Height, Tilt, and Tension Fixes

Adjusting a monitor stand means changing the height or tilt of a built-in stand, or tuning the tension on a monitor arm so the screen holds its position.

Whether you’re trying to fix a monitor that sags, or you just need it an inch higher to match your eye line, the right process depends on which stand you own. The steps are simple — but skipping the preparation is where most people go wrong. Here’s the short version of how to adjust monitor stand hardware safely, plus the fixes for sagging and stiff arms.

What Type Of Monitor Stand Do You Have?

Every monitor stand is one of three designs, and each adjusts differently. You can tell which you have in about ten seconds.

• Built-in stand: The monitor sits on a pedestal with a neck. Height and tilt adjust by sliding or pushing on the panel itself.
• Gas-spring arm: A mechanical arm with a cylinder. Tension screws keep the screen floating at your chosen height.
• Fixed arm: A rigid arm with locked joints. You loosen a lever or screw, move the monitor, and re-tighten.

Once you know the design, the adjustment process is straightforward. Before touching anything, check for a lock, lever, screw, or tension knob — forcing the screen without releasing the mechanism first is the most common mistake people make.

How To Adjust A Built-In Monitor Stand

Built-in stands adjust by hand. LG’s official guidance says to hold the monitor frame with both hands, keep the panel upright, and slide it up or down to your target height.

The method is simple, but the details matter. LG explicitly warns to always use both hands and keep the monitor upright during adjustment — using one hand can make the screen twist or slip out of position.

After you finish, re-tighten any locking levers or screws. That step prevents the monitor from drifting during use.

How To Adjust A Monitor Arm Or Clamp Mount

Monitor arms use a clamp base and tension screws. Clamp mounts need to be sitting correctly first: place the base on a stable desk edge, tighten the clamp until it doesn’t wobble, then install the arm and attach the VESA plate with the supplied screws.

Most arms support the two standard VESA patterns: 75 x 75 mm and 100 x 100 mm. Before buying or mounting, confirm your monitor matches the arm’s pattern and weight limit. Clamp desks have a thickness range too — many arms fit surfaces between 0.4 inches (1 cm) and 2.4 inches (6 cm).

If your monitor sags downward after setup, grab the supplied Allen key and turn the tension screw clockwise. If the arm is too stiff to move, turn it counter-clockwise. The same logic applies when a monitor drifts upward: turn toward the minus sign to reduce tension, or toward the plus sign to increase it.

Make small changes — about half a turn at a time — and test the motion after each adjustment. Overtightening is a common problem; the goal is smooth movement that holds position, not a locked joint.

When you’re happy with how the arm behaves, the right stand can make daily work far more comfortable. If you’re shopping for a replacement or a second screen, our tested picks for the best adjustable monitor stands cover the models worth buying.

FAQs

Why does my monitor drift down after I move it?

Your arm’s tension is set too low. Locate the tension screw near the joint, turn it clockwise with the supplied Allen key, and test after each half-turn. If the arm has a plus and minus indicator, turn toward the plus side to increase tension. Keep adjusting until the screen stays put without forcing it.

Can I adjust a monitor stand with one hand?

No. LG’s official guidance says to always use both hands on the monitor frame and keep the panel upright during adjustment. Using one hand can twist the screen or let it slip out of position. It takes two seconds longer to use both hands and it protects both the monitor and your setup.

What tools do I need to adjust a monitor arm?

Most monitor arms include the required tools in the box. A 4 mm hex key and a 2.5 mm hex key are common for tension screws, and a Philips screwdriver handles the VESA plate. Some arms use locking levers instead of screws. Check your manual before buying tools — you likely already have what you need.
