Key takeaways
- VESA pattern: Most monitors have four screw holes on the back in a square pattern, commonly 75 by 75 mm or 100 by 100 mm. The monitor’s spec sheet will say whether it supports VESA mounting. Some thin or curved monitors have unusual layouts or recessed holes and may need an adapter or extension kit.
- Weight: Check the weight of the monitor without its stand against the arm’s stated capacity range. Arms with gas springs also have a minimum weight, so a very light monitor may droop or float.
- Screen size: Makers list a maximum screen size. Ultrawide monitors are wide and may exceed an arm’s stated width even if the weight is within range.
- Number of monitors: Dual arms double the load on the clamp. Make sure the desk can take it.
The best monitor stand for a desk depends on whether you need height, flexibility or space: a simple riser such as the Rain Design mStand style suits people who only want to lift a screen to eye level and gain storage underneath, a single arm such as the Ergotron LX suits one monitor that needs to move, a heavy-duty arm such as the Ergotron HX suits large or ultrawide screens, and budget dual arms from HUANUO and VIVO suit people who want two screens on a tight budget. This guide compares them by the specifications makers state and explains VESA mounting, weight limits and desk checks.

At a glance: monitor stands compared
| Option | Best for | Key points the maker lists | Limits to know |
|---|---|---|---|
| Desktop riser (Rain Design mStand style, VIVO risers) | Raising one screen or a laptop to eye level, adding storage underneath | Fixed height platform, no VESA mounting needed, holds the stated monitor weight | Height is fixed; cannot tilt or swivel |
| Ergotron LX | One monitor, full movement | Single arm with a stated weight range of about 7.5 to 25 pounds, VESA 75 and 100 mounting, height, tilt, swivel and rotation | Does not suit very large or heavy displays |
| Ergotron HX | Large or ultrawide monitors | Heavy-duty single arm with a stated capacity up to about 42 pounds, VESA mounting, wide range of motion | Higher tier; the desk must be sturdy |
| HUANUO dual arm | Two monitors on a smaller budget | Dual gas-spring arms, VESA 75 and 100, clamp or grommet mounting, stated weight per arm | Spring tension may need adjusting; fewer finish details |
| VIVO dual or single arm | Budget flexibility and simple setup | Clamp or grommet mount, VESA compatibility, stated weight range | Check stated weight and screen size limits |
Makers update models and sometimes keep earlier versions on sale. Confirm the stated weight capacity, VESA pattern and screen size range for the exact model before buying, because small differences decide whether a monitor fits.
Riser or arm? Pick the right type
A riser sits on the desk and lifts the monitor. It is simple, needs no tools and does not require a VESA mount. It also gives you a shelf underneath for a keyboard, notebooks or a hub. It suits people who want better posture with minimal effort. The trade-off is that the height is fixed, so you adjust by adding or removing a book or a riser.
An arm holds the monitor on a pole or a clamp and lets you move it. A good arm lets you set height, tilt, swivel and sometimes rotate to portrait. It frees the desk surface, helps with multi-monitor layouts and lets you move the screen aside when not in use. The trade-off is installation and the need for a sturdy desk edge.

Desk checks before buying an arm
Clamp mounts grip the desk edge, and grommet mounts pass through a hole. Both need a solid desk thickness within the maker’s stated range. Thin glass tops, hollow-core desks, desks with a lip or a rounded edge, or those with a rear panel or drawers can make clamping tricky. Corner desks and standing desks may need a longer pole or a different clamp. Do not use a clamp on a desk that flexes under pressure, and follow the maker’s tightening instructions. If you are not sure the desk can take the load, ask a professional or choose a freestanding riser.
Ergotron LX: the dependable single arm
The LX is a well-known single arm that Ergotron lists with a weight range of roughly 7.5 to 25 pounds and VESA 75 and 100 mounting. Reviewers praise the smooth movement and the sturdy build, and note that the arm can be adjusted without tools once set. It suits one standard monitor in the 24 to 32 inch class, where the monitor weight sits within range. It is a good fit for a long-term desk setup.
Ergotron HX: for large and ultrawide displays
The HX is the heavier-duty version. Ergotron lists a higher capacity, up to roughly 42 pounds, and support for larger and ultrawide screens. It suits 34 inch ultrawides and heavier panels. It is in the premium tier, and the desk has to be strong enough to hold it.
HUANUO and VIVO: dual arms on a budget
HUANUO and VIVO make clamp-on and grommet-mount arms at a lower tier. Their dual arms let you place two monitors side by side or stack one above the other. Reviewers say these arms handle standard monitors well, but the gas springs may need tension adjustment, and the finish is simpler than premium brands. They suit home offices and student desks where a reliable, simple setup matters more than top-tier smoothness.
Desktop risers
Rain Design’s stand family and similar risers from other makers support a monitor or laptop at a fixed height. They suit people who do not want to drill, clamp or adjust and who value a clean look. Risers state their own load limit, and a heavy monitor must stay within it. A riser also works well under an arm-mounted display as a keyboard or laptop shelf.
Ergonomic positioning tips
Many ergonomic guides suggest placing the top of the screen at or slightly below eye level, with the screen about an arm’s length away. Tilt the screen slightly back so glare is reduced. If you use two monitors, place the main one in front and the second beside it at the same height. Take regular breaks and look into the distance, and speak to a healthcare professional if you have persistent neck, eye or back problems.
Pick X if…
| If you… | Pick | Why |
|---|---|---|
| Want a no-tools height boost | Desktop riser | Simple and adds shelf space |
| Have one standard monitor and want full movement | Ergotron LX | Smooth single arm with stated range of about 7.5 to 25 pounds |
| Own a large or ultrawide display | Ergotron HX | Higher stated capacity |
| Need two monitors on a budget | HUANUO or VIVO dual arm | Lower tier dual mounting |
| Have a monitor with no VESA holes | Desktop riser | No mounting pattern needed |
| Use a thin glass or hollow desk | Riser instead of clamp | Avoids clamp pressure on the desk |
Alternatives
- Wall mounts: Good if the desk is unsuitable for clamping, but they require a solid wall and correct anchors.
- Monitors with height-adjustable bases: Many modern monitors include their own adjustable stand, which may remove the need for a separate one.
- Stacked books or a box: A temporary option, though it lacks stability and is not suited to heavy screens.
Frequently Asked Questions
How do I know if my monitor has VESA mounting?
Look at the spec sheet or the back of the monitor for four screw holes in a square pattern, usually marked 75 by 75 or 100 by 100. If your monitor has none, use a riser or ask the maker about an adapter.
What is the ideal monitor height?
Many ergonomic guides suggest the top of the screen at or slightly below eye level. Adjust to what feels comfortable, and consult a professional for persistent discomfort.
Will an arm damage my desk?
A clamp can mark the surface if over-tightened or used on soft materials. Use the pads supplied by the maker and follow the instructions. On delicate desks, use a riser.
Can one arm hold an ultrawide monitor?
Only if the arm’s stated weight and size limits cover it. Many ultrawide monitors need a heavy-duty arm or a dual-arm setup designed for them.
Why does my monitor drift down on an arm?
The tension may need adjusting, or the monitor may be outside the arm’s stated weight range. Follow the maker’s instructions for adjusting the gas-spring tension.
Are monitor risers worth it?
Yes for people who want a simple height lift and extra storage. They do not allow tilt or swivel, so those who want flexibility may prefer an arm.
