Default SyncMaster S27A850 & USB3 to DP adapter - Win8

I've been using a Samsung SMS27A850 monitor, connected via its displayport to a USB3 port on my laptop for some time now (running win 7).
Adapter used: http://www.lindy.co.uk/usb-3-to-disp...ter/43171.html
Although there was some minor lag visible and video playback was choppy it was perfectly usable for office applications.

However, I upgraded to Win 8 and the lag has increased quite severely (GPU heavy rendering on Win 8?) to the point that it has become quite annoying to work on this display.

As a temporary solution, I figured I could just lower the resolution to standard HD instead of quad but that option is not availabe (I can pick either 2560 x 1440 or 1280 x 1024)...

Any suggestions? Is DisplayLink working on drivers to improve Win 8 performance?

Can you let us have the system information from here:

http://kb.displaylink.com/269

Our automated performance tests tell us that there should be no difference between Win 7 or Win 8, however there do seem to be some users that are finding a performance degradation and we need to try and understand why this is.

As a temporary solution: is it possible to force the monitor to 1920*1080 resolution?

FYI to the moderator(s):

Updating to v7.1M0 has drastically improved lag on my Displaylink monitor (at 2560*1600 resolution) on win8. There's still an occasional "hang" but that also happened when I was running win7.

I had to install it manually though, I didn't receive a new version notification and forcing a check did not find the update.

Interesting... There were a number of bug fixes in here, but nothing off the top of my head that would have changed this. Glad it is working better though!

7.1 is not on Windows update yet. We leave it a few weeks to make sure there are no major issues before pushing it out to all users.
