Default 8.6 Beta Details and How to Feedback

Hello,

I'm delighted to be able to distribute the 8.6 beta driver for Windows:

DisplayLink software release 8.6 will deliver the following:
- HDCP 1.x preview on DL-6950/DL-8020 HDMI output on Windows 10 Creators Update onwards (build 15063, v1703) with platforms (Intel 7th generation CPU + GPU) and players supporting protected content over indirect displays
- Alternate encoding 2nd developer preview (details on 8.6 Beta forum)
- Ethernet and Audio drivers will be upgraded after machine restart when upgrading from Setup.exe on Windows 7-8.1
- Bug fixes

Details on the "alternative encoder"
This feature is used to offload encoding from the CPU, and when released, will give at least the same performance as what is available in production today.
The feature is not ready for public release and that is why a manual action is required to enable it. Compared to 8.5, the performance was improved.

Current requirements of the alternative encoder
- Windows 10 Anniversary Update onwards
- USB adapter or docking station using the DisplayLink DL-6950 ASIC
- Intel GPU 4th generation and newer
- AlternativeEncoder registry = true (see below on how to do this)
Any other display connected through DisplayLink technology will still use be rendered the same way as before (DL-1x5, DL-3xxx, DL-4xxxx, DL-5xxx).

Limitations of the alternative encoder for the beta and 8.6 release
- Only DisplayLink DL-6950 ASIC currently going through alternative encoder.
- Intel GPU 4th generation and above are scoped to be supported.
- Other GPUs are not supported or even tested. Do not enable the registry key for them.
- Supported resolutions up to 4K, no tiled displays.
- No support for content protection.

How to force enable the alternative encoder
In Computer\HKEY_LOCAL_MACHINE\SOFTWARE\DisplayLink\C ore
Create new "string value" name=AlternativeEncoder data=true
If you are uncomfortable with Regedit, in an elevated command line, you can create that key by running the following:
REG ADD HKLM\SOFTWARE\DisplayLink\Core /f /v AlternativeEncoder /t REG_SZ /d true

The change will only take effect at the next connection of the USB device.

How to remove the alternative encoder
In Computer\HKEY_LOCAL_MACHINE\SOFTWARE\DisplayLink\C ore
Delete the "AlternativeEncoder" entry.
If you are uncomfortable with Regedit, in an elevated command line, you can create that key by running the following:
REG DELETE HKLM\SOFTWARE\DisplayLink\Core /v AlternativeEncoder
Confirm by typing Y, then ENTER.

The change will only take effect at the next connection of the USB device.

How to give feedback
For this to be manageable, please create a new thread with each piece of feedback you have.
Any type of feedback is useful to us, not only linked to the alternative encoder which is only developed here because it is new! For instance, we have corrected bugs in the Ethernet link negotiation area and feedback on behaviour there is encouraged.
