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

[Simon]

Hi

The lagging also seems to be gone for me with the new driver..
I have a Lenovo X1 carbon and Lenovo dock..

A thing I have noticed that may be a help to others, is that the minimum processor speed in advanced Power options need to be at least 30% when the computer is plugged in, for the dock to work properly.

You fin the option by going to:
Control Panel->Power options->Choose when to turn off the display->Change advanced power settings->Processor power management->Minimum processor state->Plugget in

My theory is that the minimum speed must be set because the most low power processors have a variable processor speed, to ensure that there is always enough processor time for the Displaylink to be serviced the minimum speed must be set.

Regards.
Simon

This is the same kind of solution that I found using my Samsung Series 9 notebook. Everybody with this kind of problem should investigate the Power Options!

The new drivers + increasing the minimum processor speed in power options have seemed to have mostly solved my issues. I still see occasional mouse lag. Perhaps the displaylink driver should set these power options by default? Or prevent the processor from going into that deep of sleep to begin with?

I have, however, noticed an issue with Windows 8, when a metro app is mounted to the side of the screen, I see the monitors flashing black occasionally. Seems to be a driver issue as this doesn't occur when using built in monitor, and haven't noticed it when plugged into the monitors through displayport.

Scratch that. Lag is still prominent, especially when switching between windows ie (alt-tab). Additionally when copying larger files over ethernet the device will appear to reset (screens go black for a second, ethernet connection is lost).

Having the same issue with my Lenovo Yoga 13.

Screen keeps disconnecting, and usb ports freeze as well as the screen freezing and going blurry.
