Graphics and mouse pointer LAG still unresolved!

Where do I post the log file? And I guess you don't need the "display link logging" since no actual error/crash occurs?

Youtube jerks at the exact same time as the mouse pointer does. When something is drawn on the screen (well except for the youtube video itself) the video jerks and the mouse pointer lags. All I'm doing is dragging the mouse pointer back and forth over the toolbar buttons on top of this message box (they turn blue).

Researched some more... if I drag the mouse around where there is nothing changing (nothing under the mouse pointer) the video and the pointer actually also jerks, but less. BUT if I drag the mouse around OUTSIDE the IE/youtube window everything is totally fine. It has to have something to do with how windows draws different elements, windows, animations with GPU/3D-planes...? Aero is enabled but windows aren't transparent since it's win 8 but I guess it's still drawing windows as "textures"? (Not my expertise this)

You can post the log file here or PM it to me. I'm interested in the machine details and the resolutions and desktop layout of your displays.

I sent it to you yesterday in PM. Any news?

Any news?

The behaviour is totally different if using extended screen och only laptop screen or only secondary screen. And actually different when only one screen is being used but laptop lid open och closed. Just look into it.

I've had a look at the logs and don't see any obvious problem. Are you saying this only happens on mirror mode and usually happens when you move over links on a web page?

I assume if it is happening in mirror mode, the jerky mouse is only seen on the DL screen and not both screens?

The problem exists only when using "second screen only" - with the lid closed! This is really strange because the laptop screen is turned off anyway. The difference is that when you close the lid, windows makes the "second screen" into the "pc screen".

Works perfectly - no lag:
When screen is extended or mirrored.

And it's not links on web pages, it's most graphics that is being drawn. Scrolling a window, elements on web pages changing color etc. BUT strangely enough some graphic changes does NOT create lag. For example the taskbar buttons, ribbon menu buttons or taskswitch thumbnails. It's like it's affected by graphics that is drawn "the old way".

The problem is also affected by network traffic. When something uses the ethernet everything lags. When downloading something everything basically comes to a stand still.

Basically it doesn't work when windows is using only one screen and that screen is the usb 3.0 dock.

Hi all

Same Problem here.

I have a Surface Pro with Windows 8.1 on it, and i have a HP 3005 PR docking station for work.

I use the latest DisplayLink Software (7.4M2)

On my docking station i have two screens connected, one with a cable HDMI/DVI and the other with a DisplayPort/DVI.

At work i don't use the surface screen.

Mouse Lag are noticeable particularly with my browser (Chrome) and less with windows in general.
