Win 8.1 update --> black display

[Carousel]

I had a hellish time two weeks back (black and blinking screens) after updating to Windows 8.1 without first getting the DisplayLink 7.4 update. Only solved this by going back to Windows 8.0 via a refresh.

But I just received an "important" Nvidia GeForce GT 750M update from the Windows 8.1 update center... And it took my screens black again. I wish this update had been flagged "optional". I would have missed it.

I got the screens working again by disabling the Nvidia device. To try this, open the device manager on the control panel, go down to the display adapter section, right-click the Nvidia driver an select disable.

I suppose this means that I do not have all the graphics capability of my PC now. Though, having an Intel 4th Gen Haswell chip, and not being a gamer, I cannot tell the difference so far.

But I hope that someone can provide a proper solution / driver or software updates.
