Internet Explorer 11 – HTML5 Black Screen

Issue

You are unable to play HTML5 videos in Internet Explorer 11, the HTML5 player displays a black screen only.

Fix

A post on the MSDN Blog states: In order to play HTML5 videos in the Internet Zone, you need to use the default settings or make sure the following registry key value 2701 under HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3 is set to 0.

However, when setting the value of 2701 to 0 in this location the value does not stick and reverts back to 3. Process Monitor showed that Group Policy was setting the value to 0, and then back to 3. Despite putting this policy last, and trying various other tactics I was unable to change this behaviour.

To apply this setting, you can also use the following key location: HKCU\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3.

When set here, the value of 2701 will not revert back to 3 (disabled), and HTML5 video playback will be enabled.

You can set this via GPP as below.

  1. Hey,

    We’re trying to implement this fix, but our users don’t have local admin (and hence can’t write to HKCU\Software\Policies).

    What suggestion would you have to try next?

    Thanks,

    Ken

      Hi Ken, if you use the GPP example above (User Configuration), it’ll run under NT AUTHORITY\SYSTEM which has sufficient rights. Tried and tested!

  2. Tom,
