2.2 fixed the CPU overload issue for me
Finally, the 2.2 Driver fixed the CPU overload issue
I have three monitors connected to my MBP, two of which are connected using two Kingston USB 2.0 adapters -DisplayLink chip, the DisplayLinkManager process v2.1 on Mavericks was using at-least 56% of the CPU at all times slowing down the computer and keeping the fans running loudly. With the 2.2 driver it's operating normally now -with the other known issues of-course. Good job! |

I have sent in logs - still seeing CPU usage of unacceptable levels and only have one monitor connected via Dynadock. The other is connected via displayport - mainly so i can close the lid and not put the MBA to sleep.
I Hope you guys fix the CPU usage and other things. Makes we want to go back to windows - Mac just can't handle multiple monitors well - even Thunderbolt is not a good solution. |

The logs won't contain CPU usage. Can you please find out how much CPU do DisplayLinkManager and DisplayLinkUserAgent use in the following cases: - No DisplayLink devices connected - One DisplayLink device connected, monitor active but no updates on the monitor - One DisplayLink device connected, monitor active and full screen video running on the monitor (please state the resolution) Cheers, Carlo |

- No display link devices connected - i did this last 0.0% - One display link connected - nothing on monitor (menu icons only) 59.9% - one display link connected - full screen video on monitor - about 62.5% - monitor is 1080P, This is with VLC. With iTunes, Displaymanager is 60%, but Windowmanager is also 60%. VLC video is 636 x 480, Itunes video 853 x 354 Plugging display link back in - -one display with nothing on it other then menu bar. jumps back to 60% |

Displaylink was at 90% CPU and Distnoted was at 120% this AM - i plugged my MBA into the Dynadock and this was the result. I disconnected everything and removed power from Dynadock and plugged it all back in now Displaymanager is running between 8 and 10% with content on the DL screen and MBA lid closed.
I hope you figure out how to make it do this all the time. |

On occasion -after the fix, the displaylinkmanager process uses 50 to 60 CPU on idle. What I do is I kill the process then it automatically restarts, the screens reconnects and the usage goes back to normal.
2 monitors connected via Kingston adapters 1 monitor connected to the display port. 3 x 1080 resolution. |

Displaylink driver seems to trigger distnoted to use ~90% CPU. Problem will persist until i disconnect the displaylink adapter and connect it again. Same issue on my Displaylink at work and at home that are different models. I think i have a DL-195 at work and a DL-3700 at home. |
