SOLUTION:
Hey Guys! This is a problem with DRM. Websites that protect their content don't show when DisplayLink is on, because the way they emulate a screen is like "recording it". To get around this, download a web browser that is not safari, go into options and disable hardware acceleration, It should work fine :)

Hello im also having the same issue with device, not sure what's taking so long to get his issue resolved. Can something be done asap about this or I will be posting on amazon above this certain issue to allow others to know not to buy.

I would also like this issue to be resolved! When trying to use Hulu on any browser on my Macbook Pro and connected to a second screen via DisplayLink, video is only a black screen and all I get is audio. The moment I disconnect from DisplayLink, the video plays just fine. This is not ideal as I'd like to be able to use my connected larger monitor!

so dope

the same issue. As a video editor, it's crucial for me to film in various places throughout the globe. Due to financial restrictions, I take use of this possibility to obtain related films and animations https://depositphotos.com/stock-footage/horse-racing.html I can save time and money by doing this. Moreover, practice generosity.

Facing the same issue. If they don't resolve this, I am returning the device

Using MBA M1 running Ventura 13.2.1 and Displaylink Manager 1.8 Alpha Build 62.127. Please fix this issue.

Same problem:

If I have Displaylink disabled video from my streaming services works. When I enable Displaylink manager, the stream goes to audio-only... black video. I'm on an MBP M1 Max running macOS 13.1 and Displaylink Manager 1.7.1 Build 60.129

Yes, fix it!

Same with Amazon Prime and Netflix here on MB Air M1.
I only hear the sound but see no picture. I assume it has something to do with copyright and screen recording permissions.
