Draw both footprints on the same desk
Trace the current stand and mark the front of the screen. Draw the position of the keyboard and mouse. For a riser, draw the shelf and all its feet. Mark how far forward it must sit for plugs and skirting. For a clamp arm, mark the base, the lower jaw and the elbow in the folded and extended positions. The arm can clear the area where the stand sat and still need extra space behind the desk.
On a 50 cm top, a 24 cm shelf and a 4 cm rear gap leave about 22 cm in front. Check your keyboard and hand position in that space. An arm might bring the screen farther forward if its joints cannot fold at the back. Use the desk-depth guide to compare the actual screen face position.
Choose an arm for movement and surface clearance
The Invision MX200 is listed for 19–32 inch screens at 2–9 kg with 75 × 75 or 100 × 100 mm mounting holes. Check the exact model, monitor weight without its stand and any adapter. Use the fitting drawing to measure the clamp and elbow against your desk. Make sure the worktop maker approves the clamp location and load.
An everyday adjustable screen
Invision MX200
The gas-assisted arm suits a single compatible screen you move between tasks. It frees the desk from a broad stand and gives you a choice of edge clamp or through-desk fixing.
A centred clamp can leave the elbow in the way of the wall. Check whether the clamp can sit to one side while keeping the screen centred. Match the fitting diagram to the base supplied.
- 19–32″
- 2–9 kg
- VESA 75 × 75 or 100 × 100 mm
If you regularly turn a screen for calls or move it closer to read, test the positions you actually need. Allow for the moving cable loop and any nearby shelf. A useful range is the distance the arm can travel with everything connected and clear.
Choose a riser for a modest lift on the original base
The Duronic DM052-2 has a 56 × 24 cm platform and a published lift of 9–10.5 cm. It retains the screen’s original stand, so weigh the complete monitor and base against its 20 kg limit. Trace the full stand and confirm that every contact point sits on the usable platform.
For a shallower platform
Duronic DM052-2 glass riser
A 24 cm-deep glass platform with adjustable feet to set a small range of screen lift.
Check the entire base and the glass platform’s instructions, including the weight of the screen with its stand.
- 56 × 24 cm platform
- 9–10.5 cm height
- 20 kg listed load
If the original stand already raises the screen, set that first and measure the extra lift you need. A 9 cm riser may suit a low pedestal and be too high for an adjustable monitor at its upper setting. Measure the open space beneath the platform separately if you plan to store a keyboard there.
Choose by the problem that remains
Try the original stand at a different height or depth before buying. If it already gives you the screen position and work area you want, leave it in place. If you just need more height and have room under the monitor, a riser keeps the change simple. If the stand is taking up working depth or the screen needs to move often, shortlist an arm after checking the desk and display. Use your normal work task to confirm the result rather than judging from the room doorway.
Common questions
Which option saves more desktop space?
A clamp arm usually removes the original base from the top. Compare the clamp and sweep, and check what you can actually use beneath a riser.
Can I use a riser without VESA holes?
Yes, if the original base fits the riser and both the surface and riser support the total load.
Will an arm make my screen sit farther back?
Check the arm’s folded geometry and the space behind the desk. Some joints push a screen forward near a wall.
How much height should a riser add?
Measure your preferred screen position and subtract the height you can reach on the original stand.
What if the desk cannot take a clamp?
Consider the original stand, a suitable riser or an approved freestanding mount with a stable base.
