Blank screen in yosemite

And here's my second try for log upload below:

Hi Sean,

So for the hub issue:
The logs show the device being briefly recognised but no longer being reachable at some point. It could still be a problem with the hub or maybe you have some virtualisation software running that is set up to capture the device? I'd check the settings for VirtualBox for example.
Unfortunately I can't tell from the logs the silicon manufacturer for the hub. One experiment to try is using a USB 2 cable between hub and device. Another using the hub with no other devices connected to it.

For the corruption issue:
Could not find specific errors in the logs. A picture of the display (not a screenshot) showing the corruption would give a pretty good idea if it's SW or HW.

Cheers,
Carlo

Hi - just wondering if there's any update on the HDCP problem when trying to play iTunes purchased movies with the DisplayLink driver installed?

Mac OSX 10.11.2
Using StarTEch USB3 - HDMI - model USB32HD4K
DELL U2515H as second screen to iMac

Even if I run in the iMac screen, same problem.

"This movie can be played only on displays that support HDCP (High-bandwidth Digital Content Protection).

Try moving the iTunes window to a different display. Make sure the entire window is on the supported display."

No updates I'm afraid.

Apple has told us this is the intended behaviour while using the interfaces we have to use (yes, even playing on the internal screen...).We don't expect any changes to this outside of major OS upgrades.
