    Frequently Asked Questions

    What screen sizes does this arm support?

    It is designed for screens from 17 to 57 inches, including large curved and ultrawide panels. It holds one screen at a time and fits both flat and curved displays.

    What is the maximum weight it can carry?

    Up to 27 kg with a flat screen and up to 22 kg with a curved screen. Weigh your monitor without its stand before ordering, and leave some headroom rather than running at the limit.

    Will it fit my desk?

    The desk clamp suits desktops from 10 to 45 mm thick and the grommet mount suits 10 to 40 mm. Both are installed from above the desk, so there is no need to reach underneath.

    Does it fit a large curved display such as the Samsung Odyssey Ark?

    Yes. VESA adaptor plates are included, so the arm covers the wider mounting patterns these displays use, from 75 x 75 up to 200 x 200 mm. Some G9-series Samsung models that recess their mounting points need a different adaptor, available separately as EA-XMA1401.

    What are the USB ports for?

    The base carries USB-A and USB-C ports for connecting devices at the desk, so your phone or accessories can be plugged in at the arm rather than behind the computer.
