Wow - can't we get any official comment on this?
nVidia's new driver, the official 344.48 does not correctly work with the current displaylink drivers either.

The control panel is still not available after activating the auxiliary USB screens. Also it seems to have some problems with performance on the main display when haven nVidia Surround and SLI activated.

So - this is somewhat important to all people who would like to setup a simpit or at least some home cockpit.

Get it to work, please! And please get an estimate or at least some response here!

We cannot solve this without NVIDIA help to know why this is happening. So far we have had no joy in getting help from NVIDIA on this, so we are blocked trying to find a solution.

Wim - thank you for your answer! At least I see you guys are onto it.

driver #
 

Do you have a recommendation of driver version # to use where I could still use my 7" display with my nVidia video card?

OK - I tried and still have the issue with Displaylink's 7.7 M2 and nVidia 347.09. I even contaced nVidia support on the issue and after they have gotten a lot of system info from me, they never got back to me...

I measured with and without USB screens inserted and benchmarked the system with 3D Mark. There was no change in performance. So I guess you can use these screens without decrease in system performance.
Also it seemes that the driver is stable with connected USB screens.

You just need to plugin the USB screens, after booting Windows. If you want to change settings on your nVidia card, you need to unplug the USB screens first.

It is not a totally satisfactory result, because it remains inconvenient, but at least I can play my games the way I like to see them.
