Win8 Lenovo X1 Carbon with USB 3 Dock: Display Artifacts

[mskovrinskie]

The odd pixellation thing seems to work itself out but a fix would be nice. The mouse lag and pauses is another thing. Is this on the radar for a fix too?

I think the mouse pausing is for the same reason as the pixelation... we're working on changes to improve this.

Thanks

so happy to hear this is being worked on. i am experiencing the exact same issues with monitor resolution and the mouse pausing; i'm using the S230u (twist) with the Thinkpad 3.0 dock and win8 64 bit installed.

also have no issues when my monitors and mouse adapter are plugged directly into the laptop.

looking forward to an update as the mouse pausing is highly frustrating.

thanks.

I'm using a Samsung Series 9 and an i-Tec USB 3.0 Dock with Win8 x64 and i'm experiencing the same problems. Screen compression artifacts (blockiness, sudden color changes because of this, halting mouse) while moving the mouse or loading a webpage in a full screen Chrome. Please fix this, i don't like to downgrade to Windows 7 just because of this.

If there's any beta drivers available for testing please let us know. I would gladly try them and report for you.

As i experienced the Win8 DisplayLink driver currently sends the whole screen and not just the changes as a delta when a screen update occurs. This introduces the artifacts because the USB bus runs out of bandwidth. When this occurs it reduces the image quality to meet the restrictions but for me it seems that this is decided from frame to frame and this is what creates the flashing effect.

My question is: is it possible to override the default picture quality? Maybe a hidden registry key or something like that. I wouldn't mind some image artifacts if they stay constant. At least until the driver fix cames out.

I posted another thread on the same issue, I too am willing to help beta test drivers.

Here is the thread I posted w/ my attached diagnostic information:

DisplayLink: Where did the three posts go that describe the registry keys that improve the display performance? They were the only thing that has been prescribed so far that improved the symptoms while we wait for a driver fix.

Were these posts deleted without notifying the authors? I know that I, for one, put in a fair amount of effort to try to determine a setting that would help other users. To see that effort wiped out is frustrating, to say the least!
