Hello Alex,
Which version of Windows are you using?
Netflix requires HDCP 2.2 with hardware encryption. This is a timely question as we're delivering it before Christmas on platforms it can work on.
You would need an Intel 7th Generation CPU and GPU.
Then, our driver 8.4 Alpha will make the film play at up to 1080p.
Strictly speaking, Netflix should work even if HDCP is not present, but at a lower quality than Full HD. This is up to the player to decide if they want to play or not.
You can download the 8.4 Alpha and feed back from the forum:

8.4 also includes mouse cursor speed improvements.
For more customised advice, please upload the machine logs gathered with the customer support tool. The last link of my forum signature explains how to use that tool. Only DisplayLink employees can download these from the forum.
IMPORTANT: do NOT update to Windows 10 FALL Creators Update (v1709) if you wish to use Netflix through indirect displays like DisplayLink. HDCP is broken on it for now and we're working with Microsoft to get it fixed and the fixed pushed to everyone.
Kind regards,
Alban
