When multiple displays are used on a single support, they cannot be effectively adjusted relative to each other about a vertical axis. When multiple displays are used on independent arms, they can be difficult to align in a smooth and precise way due to inconsistent counterbalancing and arm lengths. These individual stands or arms unnecessarily take up large spaces, are often aesthetically unpleasing, overcomplicated, and have inefficient redundant mechanisms. When users use multiple displays in a workspace, the displays are generally supported by multiple different individual stands or by independently-movable arms that extend from a single support point. The filing explains why the Dual Display Stand solution may be better than existing third-party stand solutions such as independently-movable VESA-mount arms: The patent also stresses that the shuttles on the continuous rail provide 'smooth, consistent contact' with the rails despite adjustments to the support bar using wheels.

The patent notes that the entire bar is lifted regardless of the angle of the support bar or which handle is turned. The stand has handles on each side that can be twisted to easily adjust the height of the support bar for exact vertical adjustment. A central joint on the support bar allows the stand to adjust the angle between the displays. The stand seems to use the same moveable joints as the existing Pro Stand for the Studio Display and Pro Display XDR, but places them on rail shuttles for horizontal adjustment.

The display stand provides improved smoothness, rigidity, and comfort for the user to support and use multiple displays on a single stand. Apple offers a brief description of the improvements offered by the stand in the patent: The stand allows for a high level of precise adjustment and control, with vertical, horizontal, and center pivot degrees of freedom. The filing outlines a large display stand with two spaced-apart legs, connected by a horizontal support bar that allows two displays to be mounted. The granted patent, spotted by Patently Apple, is simply titled ' Dual Display Stand,' and details a mechanical design that seeks to address the shortcomings of existing multi-display solutions, offering easy and precise adjustment for up to two external displays.

The patent filing first surfaced in 2020, but now the United States Patent and Trademark Office has officially granted Apple the patent. Apple has won a patent for a dual monitor stand that appears to be based on the ' Pro Stand' design option for the Studio Display and Pro Display XDR.
