M1 MBA - no video in standalone browser windows
 

Recently bought the Anker 563 USB-C, and installed it without challenge. It runs my M1 MBA native and two external Dell U2417H monitors.*One is HDMI, one Display Port

Video will not be visible running on YouTube TV, Netflx, Hulu, or Apple TV - you get video previews, full sound, but no video. I have these applications running in Chrome as stand-alone windows. None are 4k video.*

If I disconnect one Dell, video appears.*

YouTube itself runs perfectly, but running in a browser.*

Behavior is the same if I switch Display Port to a 2nd HDMI

Thoughts?*

thanks,*

I'm having the same issue. The problem is the new copyright protection rules. DiplayLink apparently doesn't support playing HDCP content. Here's where I found that information: https://kb.plugable.com/displaylink/...-based-product

Others within this forum have reported that:

A. Disabling the 'Use hardware acceleration when available' option within the Chrome browser's 'Settings' --> 'Advanced' --> 'System' menu

or


B. Using the Firefox browser

Can workaround the behavior described by the original poster.

Thanks! I've been working with Anker support on this in parallel. They identified the issue with the HDCP above, and I'll give the the two suggestions proposed above a shot.

Appreciate the help, and I'll let you know the results.

That was quick.

Disabling hardware acceleration in the browser worked perfectly on YTTV, Netflix, Hulu.

For the record, I didn't try the Firefox solution, as the first option worked, so haven't verified it. Will keep in my back pocket.

thanks again!
