Hello Dual-Displays.

Now on your M1, M2 & M3 Mac.

Oh and BTW… it works with USB-C and Thunderbolt Macs & PCs too 😉

When the first generation of Apple Silicon Macs were introduced, we immediately fell in love with the M1's ability to rival – and even go faster and run cooler than - higher-end, more expensive machines. The launch of the M2 and M3 with their performance and power efficiency improvements made us as giddy as any geek unboxing a new gadget. However, our excitement and praise about Apple's latest innovation once again waned considerably when we discovered the base M3 model (meaning not M3 Pro or M3 Max) shares the same single external display limitation as the previous M1 and M2.

Say hello to the OWC USB-C Dual HDMI 4K Adapter. It’s the DisplayLink powered solution for expanding your M1, M2, and M3 machine’s digital window for easier video editing, seeing more of your workflow simultaneously, or even creating eye-catching digital signage. For the ultimate in convenience, we gave this compact, bus-powered adapter a USB-C power pass-thru port so you can charge/power your laptop.2 Being the leading dock innovator for Macs, we know you love having ports freed up on your machine!

From working all-at-once in multiple programs like Photoshop, Final Cut, DaVinci Resolve, Logic Pro, Sketch, and Affinity Photo, to viewing all your Internet “research” – Calvin and Hobbes micro-breaks are part of well-balanced workflow, right? – you’ll be project-hopping, app-swapping, and producing with greater ease than any single-display workflow can achieve.

And when it comes time to share all your awesomeness, what better way to collab with your team than having a vast digital window to showcase it all? You'll have room-a-plenty to riff ideas, travel multiple paths, and expand on your concepts with ease.


Expand your followers with more digital space to edit, find, and respond to content, comments, mega fans, and if you must… trolls. Not the ones that live under bridges and in caves, the much-much worse online variety. 😀

Keep tabs on ever-important social media vitals to keep the posts, reposts, views, and likes flowing. All that extra display space expands a new world of content creation workflows so nothing will hold you back from enrapturing your audience with stunning videos, photos, and content.
