Windows 8, Lenvo USB 3.0 dock = lag + fuzzy image

jonlove · 04-05-2013, 07:48 PM

Just wanted to echo that I also have the same problem... Windows 7 (64 bit) with the latest Displaylink drivers for the Lenovo USB 3.0 dock.

Very frustrating - it does feel a lot like operating through a remote connection. I have one VGA monitor and one DVI, and it is noticeably worse on the DVI connection (which is higher resolution).

Happy to help debug at all but would be great to find a solution, otherwise having 2 external monitors is not going to last long.

thanks for the update!
i've tested a bit with the new driver but i think the performance is nearly as slow as before.
if you need some information or can build a beta/debug driver i'm happy to help!

My impressions for 7.2 driver update.

Still running Lenovo X1 carbon and Lenovo USB 3.0 dock with 2 x external monitors and nothing else. Both running DVI @ 1920x1200.

- Blurry image seems to have gone. Moving my mouse pointer over the task bar now does not produce blurry icons.
- Mouse lag still present and even worse than before. Mouse pointer freeze for about one second every few minutes.
- CPU usage still high from the DisplayLinkManager Application 5-30% constant.

So one step forward - one and half back.

Ignore me - it's still the DVI monitor/highesr res that seems to be worse for me

I am running a 2560x1440 monitor through the HP3005pr USB3.0 dock. I have also had pixelation issues, but after 7.2M0 this is completely gone!

I still have minor lag on the mouse from time to time.

It is a Samsung series 9 laptop.

PS: In the "Samsung Settings" application, there is a tab called "General - Silent Mode". If I select anything else than "off", the display becomes terribly choppy! This might be a tips for anyone with choppy displays. Check your power saving options!

So - I swapped out my VGA cable for a DVI. Even though previously the higher res monitor on the DVI cable was slower (and I swapped the other cable), that seems to have helped fix it.

e.g., before I had:
- Monitor 1: DVI -> VGA adapter, VGA cable - running fine
- Monitor 2: DVI cable - running slow

Replaced monitor 1's cable for a straight DVI, and monitor 2 seems to be running normally now.

Not sure if that's helpful or not.
