Before installing a monitor mount on a small desk, check three compatibility points: that of the monitor with the mount, that of the mount with the desktop, and that of the entire setup with the available space. The screen's diagonal measurement alone is not enough to make a decision.
A monitor arm can free up part of the desktop, but its base, clamp, and movements also require space. The goal is to gain truly usable surface area without creating a difficult-to-adjust setup.
1. Gather monitor and mount specifications
Note your monitor's model number, its weight without the stand, and its mounting system. If VESA mounting points are present, compare their spacing with that accepted by the mount. Also, check the required screws and the shape of the monitor's back.
The Modoja product page features a dual mount for a 13 to 27-inch monitor and a laptop. This size range alone does not confirm compatibility with your equipment. Maximum loads, accepted VESA patterns, and laptop tray dimensions must be checked before purchase.
Measure the laptop closed and then open. Identify the vents, side ports, and the space needed to plug in its power supply. A tray should neither prevent the device from resting properly nor obstruct the openings provided by its manufacturer.
Do not consider the laptop tray as a mount for a second screen; these are two different uses.

2. Check that the desk can accommodate the mounting mechanism
Inspect the edge of the desktop, both above and below. A crossbar, cable tray, drawer, or lip can prevent a clamp from installing correctly. Measure the thickness at the exact spot where it will be placed.
The material also matters. A hollow, very thin, fragile, or glass desktop should not be considered compatible without explicit indication. Follow the recommendations for both the desk and the mount; a large visible surface area is not a guarantee of local resistance.
Then check the space behind the desk. The arms and cables may require additional clearance. Also, simulate lateral movement to prevent a screen from hitting a shelf or window.
For a folding desk, include the folding mechanism in these checks. A permanently installed mount can hinder folding or alter the stresses on the furniture.

3. Assemble in the prescribed order and adjust gradually
Follow the mount's instructions for the order of parts, screws, tools, and tightening. This guide prepares for installation; it does not replace the specific instructions for the mechanism.
Protect the monitor during handling, turn off its power, and disconnect cables before mounting it. If the instructions suggest a two-person installation, prepare the space accordingly. Do not release the device until the necessary fixings are in place.
Make adjustments without exceeding the intended ranges of motion. An arm that descends, pivots on its own, or requires unusual force warrants a check of its assembly and load, rather than improvised tightening.
Route cables without hindering movement
First, set your desired working position, then organize the cables. Leave enough slack near joints and ports for permitted movements. A tightly stretched loop can pull on a connector when the screen pivots.
Keep connections accessible. Cable ties should group cables without crushing them. Check the entire setup in the various positions you actually use, especially if the laptop is regularly removed from the tray.
To work with a raised laptop, provide a separate keyboard and mouse adapted to your setup if necessary. The mount positions the device; it doesn't automatically transform the entire setup into an ergonomically adjusted workstation for you.

Frequently asked questions
Is a 24-inch monitor necessarily compatible?
No. You also need to check the weight, mounting points, the back of the monitor, and the screws.
Can the clamp be fixed to any desk?
No. Check the material, thickness, contact area, and manufacturer's limits. The desktop's characteristics take precedence over its appearance.
Does the mount always save depth?
Not necessarily. The clearance required for the arms can reduce the gain. Measure the complete installation, including the monitor and cables.
