Thank you for that information.
Our TBT3-UDZ dual display docking station would be a great match for your Razer Blade Stealth laptop.
This docking station offers a choice between dual HDMI and DisplayPort displays via a single Thunderbolt 3 connection.
Our Thunderbolt 3 dock will have no issues driving both of your Dell S2721D monitors.
The product should also work in the same configuration with an M1 Mac as I could buy one later this year.
The M1 MacBook Pro and MacBook Air only support a single external display per Apple specifications due to limitations with the M1 graphics.
Unfortunately, two monitors will not be possible with any Thunderbolt 3 dock, such as our TBT3-UDZ docking station with these first-generation M1 systems.
Alternatively, we offer USB graphics solutions that use a technology called DisplayLink, which can get around this single native display limitation.
A great option for the M1 MacBook and Razer Blade laptop is our UD-ULTC4K triple display docking station.
This dock features 3 video outputs, including 1x HDMI 1.4 output capable of 4K 30Hz, and 2x DisplayPort 1.2 (DP++) outputs capable of 4K 60Hz.
This adapter would allow you to drive up to three displays via a single USB-C connection to your M1 Mac and Razer Blade laptop and function great for general office or productivity use.
However, one important detail to keep in mind is that you will need to install the adapter’s DisplayLink application manually. You can refer to the following blog post for installation instructions for Big Sur: https://plugable.com/2020/11/13/plugable-displaylink-products-and-macos-11-big-sur-macos-10-15-catalina-and-macos-10-4-mojave/.
We also have a blog post covering more details about adding monitors to M1 Macs if you’re interested: https://plugable.com/blogs/news/how-to-connect-more-external-displays-to-apple-silicon-m1-macs.
I buy to be able to use my 2 external display through this OWC dock ?
Lastly, our thunderbolt 3 docks are recommended to connect directly to the host system. This should work as expected via the OWC Thunderbolt Hub based on the specs. We cannot guarantee functionality since this is not a configuration that we have tested.
I hope I was able to answer your question!
Please reach out with any additional questions or concerns.
Thank you for considering Plugable!
