Contact us with your monitor models and weights to confirm compatibility before ordering.\u003c\/p\u003e\n\n\u003ch4\u003eCan I use this with different sized monitors?\u003c\/h4\u003e\n\u003cp\u003eYes! The independent counterbalance adjustment allows each monitor to be positioned perfectly regardless of size or weight differences. Each arm adjusts independently to support its specific monitor.\u003c\/p\u003e\n\n\u003ch4\u003eHow do I know if my monitors are VESA compatible?\u003c\/h4\u003e\n\u003cp\u003eCheck the back of your monitors for a square mounting pattern with 4 screw holes. Measure the distance between holes—75mm × 75mm or 100mm × 100mm patterns are VESA standard. Most modern monitors are VESA compatible.\u003c\/p\u003e\n\n\u003ch4\u003eDoes this require tools to adjust monitor position?\u003c\/h4\u003e\n\u003cp\u003eNo! Humanscale's counterbalance technology allows effortless adjustment with just a fingertip touch. No knobs, levers, or tools required for daily positioning changes. Initial tension adjustment may require an Allen wrench (included).\u003c\/p\u003e\n\n\u003ch4\u003eWill this work with my standing desk?\u003c\/h4\u003e\n\u003cp\u003eYes! The M8.1 works perfectly with standing desks. The monitors move with the desk as it raises and lowers, maintaining optimal positioning in both sitting and standing positions.\u003c\/p\u003e\n\n\u003ch4\u003eHow much desk space does the crossbar mount require?\u003c\/h4\u003e\n\u003cp\u003eThe single mounting point requires minimal desk space compared to dual separate arms. The desk clamp attaches to desk edges up to 2.5\" thick. The grommet mount requires a 0.375\"–0.5\" hole drilled through the desk surface.\u003c\/p\u003e\n\n\u003ch4\u003eCan I install this myself or do I need professional installation?\u003c\/h4\u003e\n\u003cp\u003eMost users install the M8.1 themselves in under 30 minutes using basic tools.

Feed cables through the channels before connecting monitors, or use the access points to add cables after installation. The channels accommodate multiple cables per monitor (power, display, USB).\u003c\/p\u003e\n\n\u003ch4\u003eWhat's the difference between the M8.1 and M8.1 with Handle?\u003c\/h4\u003e\n\u003cp\u003eThe M8.1 with Handle includes an integrated handle on the crossbar for easy repositioning of both monitors simultaneously. The standard M8.1 (this product) adjusts each monitor independently. Choose based on whether you want synchronized movement capability.\u003c\/p\u003e\n\n\u003ch4\u003eCan I add a third monitor later?\u003c\/h4\u003e\n\u003cp\u003eThe M8.1 crossbar supports two monitors. For three monitors, consider combining the M8.1 with a separate single monitor arm, or explore Humanscale's triple monitor arm solutions.\u003c\/p\u003e\n\n\u003ch4\u003eWhat colors are available?\u003c\/h4\u003e\n\u003cp\u003eThe M8.1 is available in Silver with Gray Trim, Polished Aluminum with White Trim, and Black with Black Trim.
