The Best Monitor Mount for Desk

From the ErGear pole single to the Amazon Basics single: five monitor arms ranked on screen size limit and load rating, with who should skip each one.

By The PC Journal editorial team

12 min read5 products evaluated

A desk monitor mount frees the space under the screen and lets you set its height. Check the VESA pattern and weight limit first.

Our comparison rests on published figures for max screen size, max load per arm and monitors; nothing here was tested in-house, and where a maker leaves out tension, we say so.

Our Picks

ErGear Single Monitor Mount (13-32 in)

Lowest Price Here1 of 5

ErGear Single Monitor Mount (13-32 in) on Amazon (opens in a new tab)

ErGear's pole-mounted single arm holds 13 to 32 inch screens up to 17.6 lb.

Best for

Spending as little as possible.

Skip if

Choose another pick if you can't accept this: screen size limit of 32 in, behind the Amazon Basics single (38 in).

Why we like it

On screen size limit it sits mid-pack at 32 in: the Amazon Basics single comes in at 38 in, and the Amazon Basics gas single comes in at 27 in. On load rating it sits mid-pack at 17.6 lbs: the WALI single is rated for 26.4 lbs, and the Amazon Basics gas single comes in at 15.4 lbs. It also offers a 17.6 lb limit and the lowest price among the arms here.

Check the back of your monitor for a 75x75 or 100x100 VESA pattern before ordering the ErGear pole single; curved and some slim monitors need an adapter. Confirm your desk edge fits the ErGear pole single's clamp range and has no rear lip or drawer rail in the way. No other pick here cost less at our last price check, and the WALI single was closest.

How We Chose

Each pick was assessed across 4 criteria weighted for real-world use.

Adjustment
We noted gas, mechanical spring or pole-collar height adjustment.
Load rating
We recorded the per-arm weight range each listing states, including curved-screen limits where given.
Screen size
We noted the maximum screen size, including ultrawide figures.
Mounting
We checked clamp and grommet options and listed desk thickness ranges.

What to Look for in a Monitor Mount for Desk

Key buying criteria so you get the right fit the first time.

  1. How much load rating you need

    Among these picks, load rating runs from 15.4 lbs on the Amazon Basics gas single to 26.4 lbs on the WALI single. Match this to what you will actually do with it, then let price decide between the picks that qualify.

  2. Weigh the monitor without its stand

    Arm ratings are per arm and include a minimum as well as a maximum. Weigh the panel alone, since the stand is removed.

  3. Screen size limits are about leverage

    A 34 or 49-inch ultrawide puts more leverage on the joint. Use an arm listed for that size, not only that weight.

  4. Gas and mechanical springs

    Spring-assisted arms let you move the screen with one hand. Pole-mounted arms adjust height with a collar and a tool.

  5. Dual arms and desk depth

    Dual arms share one pole or clamp. Check the arm reach against your desk depth so both screens can sit at arm's length.

Frequently Asked Questions

How do these monitor arms compare on screen size limit?

The Amazon Basics single leads at 38 in, ahead of the WALI single at 34 in; the Amazon Basics gas single sits at the other end with 27 in.

Which is the cheapest pick in this guide?

Start with the ErGear pole single, the lowest-priced pick when we checked. The Amazon Basics single is the premium end, so the spread between them shows what extra money buys here.

Why does my monitor drift up or down?

The spring tension does not match the screen weight. Adjust the tension screw on the arm's elbow or base.

Do monitor arms work with curved screens?

Yes if the curved monitor has a VESA pattern. Some arms list a lower weight limit for curved panels.

How do I know if my monitor fits an arm?

Look for four screw holes on the back, 75mm or 100mm apart. If there are none, the monitor needs a VESA adapter or cannot be mounted.

Bottom Line

Our first pick is the ErGear pole single, chosen for a lower price than the WALI single and the rest when we checked. Look at the WALI single for the highest load rating here (26.4 lbs), the Amazon Basics gas single for a gas spring tension and the ErGear single for a 13 to 34 inch screen range if those matter more to you.

Clamp mounts need a desk edge of the thickness.
