Why is only one external display working with my Apple M1 or M2 Mac? - StarTech.com IT Pro Community
<main> <article class="userContent"> <p>Late 2020 models of MacBook Air, MacBook Pro 13-inch, and Mac Mini systems using the original Apple M1 or 2022 models of MacBook Air, and MacBook Pro using the Apple M2 chip support only a single external display over the Thunderbolt 3 ports, even when connected to a Thunderbolt 3 docking station or adapter with more than one video output. This limitation also applies to using multiple Thunderbolt or USB Type-C display adapters on both Thunderbolt/USB Type-C ports.</p><p>This is not a limitation of StarTech.com products specifically, and Apple lists support for only one external display in the Tech Specs for <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.apple.com%2Fmacbook-pro-13%2Fspecs%2F" rel="nofollow noreferrer ugc"><strong>Video Support on the M1 MacBook Pro 13”</strong></a> [external link to apple.com]. Turning off the laptop display or using clamshell mode does not change this.</p><p>One option that allows for more than one external display with an Apple M1 or M2 silicon is to use a USB-C DisplayLink-based docking station or video adapter that requires a driver install. One dual monitor example is our DK30CHDDPPD, but please contact StarTech.com support for a recommendation based on your specific setup.</p><p><em>Please note: this single monitor limitation does not affect Intel-based Macs with Thunderbolt 3, or later M1 models that ship with M1 Max, M1 Pro, or M1 Ultra processors.</em></p><p><strong>For more information on this topic, please check out our blog post: </strong><a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fblog%2Fapple-m1-m2-multi-monitor" rel="nofollow noreferrer ugc"><strong>Multi-Monitor Solutions for Apple M1 / M2 System Deployments</strong></a></p><p><br></p><div class="blockquote"><div class="blockquote-content"><p class="blockquote-line">This FAQ applies to these products:</p><p class="blockquote-line"><a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Faudio-video-products%2Ftb32dp14" rel="nofollow noreferrer ugc">TB32DP14</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Faudio-video-products%2Ftb32dp2t" rel="nofollow noreferrer ugc">TB32DP2T</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Faudio-video-products%2Ftb32hd24k60" rel="nofollow noreferrer ugc">TB32HD24K60</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3cdk2dh" rel="nofollow noreferrer ugc">TB3CDK2DH</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3cdk2dp" rel="nofollow noreferrer ugc">TB3CDK2DP</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3cdockdp" rel="nofollow noreferrer ugc">TB3CDOCKDP</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3dk2dhv" rel="nofollow noreferrer ugc">TB3DK2DHV</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3dk2dpm2" rel="nofollow noreferrer ugc">TB3DK2DPM2</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3dk2dppd" rel="nofollow noreferrer ugc">TB3DK2DPPD</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3dkdpmaw" rel="nofollow noreferrer ugc">TB3DKDPMAW</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3dkm2dp" rel="nofollow noreferrer ugc">TB3DKM2DP</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3dkm2dpl" rel="nofollow noreferrer ugc">TB3DKM2DPL</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3dkm2hd" rel="nofollow noreferrer ugc">TB3DKM2HD</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3dkm2hdl" rel="nofollow noreferrer ugc">TB3DKM2HDL</a> <a href="https://community.startech.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.startech.com%2Fen-us%2Fcards-adapters%2Ftb3dock2dppd" rel="nofollow noreferrer ugc">TB3DOCK2DPPD</a> TB3DKDPMAWUE TB3CDK2DHUE TB3CDK2DPUE TB3DK2DHVUE TB3DK2DPPDUE TB3DOCK2DPPU</p></div></div> </article> </main>
