Choose a full-motion single arm if you need to reposition one reference screen while drawing; choose a dual arm if your drawing display and reference display must stay visible together. Check each monitor’s VESA fixing pattern and weight, along with the desk attachment, before comparing movement features. A heavier-duty arm is worth considering only when the exact display falls within its stated load and depth limits.
If one display shows your references, an adjustable arm lets you bring it closer, move it aside or change its orientation while keeping the desk available for drawing. Check that the monitor and desk suit the arm’s stated limits.
If you draw on one display while keeping references visible on another, a dual arm can position the screens separately. Check the capacity of each arm and the space needed for its desk attachment.
A heavy, deep or ultrawide display calls for checks beyond screen size. Compare its actual weight, fixing pattern and depth with the exact arm’s specifications before choosing a mount.
Choose it when: You reposition one reference display as your drawing task changes.
Trade-off: It does not provide a mount for a second screen.
Choose it when: Your drawing canvas and reference display need to remain visible at the same time.
Trade-off: Both screens need room to be positioned, and each arm has its own load limit.
Choose it when: A larger or heavier display exceeds the limits of a standard arm but fits a specific heavy-duty model.
Trade-off: The higher stated load limit may still depend on display depth or the tilt fitting.
| Concern | What to check | Who this matters to |
|---|---|---|
| Repositioning references | Compare the exact arm’s height range, reach and rotation with the positions you use for drawing and viewing references. | If I often pull a reference closer or turn it upright, I need the screen to move without shifting my drawing area; around 27% of consumers put repositioning first. |
| Monitor and desk compatibility | Check the display’s VESA pattern, actual weight and relevant depth limits, then confirm the mount fits the desk’s thickness and edge. | Before I mount a heavy or unfamiliar monitor, I want to know that both the display and desk attachment fit; for around 33% of consumers, compatibility is the primary concern. |
| Drawing space | Measure free desk-edge space and nearby obstructions; check how far the arm folds back and where its clamp sits. | When my tablet or sketchbook shares a small desk, I need room to work while keeping references in view; roughly 20% of consumers prioritise usable drawing space. |
| Two visible screens | For a dual arm, compare each monitor separately with its arm’s VESA, size and weight limits. | If I draw on one screen and keep references open on another, I need both visible without overloading either arm; around 20% of consumers make the two-screen setup their main priority. |
A monitor can fit an arm’s advertised size range yet fall outside its VESA or weight limits. Ergotron also notes that display depth can affect capacity on its HX arm.
Find your monitor’s fixing pattern, actual weight and depth, then compare them with the specifications for the exact arm variant.
A suitable monitor arm may still be difficult to install if the desktop is too thick or the underside and rear edge are obstructed.
Measure the desktop and inspect the area below and behind it. Choose a clamp or grommet mounting option only if its stated installation limits suit your desk.
A dual arm’s limit may apply to each display separately. One heavier drawing monitor can exceed its side’s limit even when the pair appears to fit.
Check the VESA pattern, weight and size of each monitor against the corresponding limits of the exact dual-arm model.
Moving the screen is only part of arranging a drawing desk. The Health and Safety Executive also advises attention to chair adjustment, input devices, lighting, glare and breaks.
After fitting the arm, adjust the screen and the rest of the workstation together, then check viewing distance and glare during your usual drawing tasks.
Its LX and HX desk-arm ranges cover different display loads, including heavier-monitor configurations.
Its monitor-arm range includes single-screen configurations and crossbar options for buyers considering how their screens will move together.
Its cited single and dual desk-mounted arms state model-specific VESA, load and clamp requirements.
Place the screen directly in front of you where your workflow allows. The Health and Safety Executive advises a viewing distance of about an arm’s length and a screen top around eye level for a standard display-screen workstation; adjust the rest of the workstation as well as the arm.
No. Check the exact arm’s VESA pattern and weight range against your monitor, and read any model-specific depth conditions for a large or deep display. Ergotron says a display deeper than 15 cm can affect capacity on the cited HX arm.
Measure desktop thickness, usable edge space and clearance below and behind the desk. StarTech.com specifies a 2–6 cm desk-clamp range for its cited single arm and a clamp limit of up to 60 mm for its cited dual model; other arms may have different requirements.
