Video Adapter - sudden slow performance

I bought the adapter a couple of months ago and it's been working like a charm ever since but suddenly for some reason it stopped working properly. The screen rendering has gotten so slow that it lags when I type anything. Browsing is a nightmare (on all browsers) and obviously playing any videos is not even an option with that kind of rendering speed (it used to work just fine).

The only thing that I did which started all of this is that I installed a windows update that led to a computer restart. From there, the adapter became insanely slow when it renders anything on the screen.

model Plugable adapter:
UGA-2K-A USB 2.0 to VGA/DVI/HDMI Adapter

O.S:
Windows 7

    Hi Moayad,

    Thanks for posting here! We've had a flood of tickets yesterday because a Windows update deployed by Microsoft on 2/27/2013 is leaving Windows systems in Basic mode, which then causes problems because the most stable drivers for Windows 7 depend on Aero to work well.

    All the cases got resolved by doing a system restore. If you are unfamiliar with it, here is a link to a post which explains how to do it: http://pcsupport.about.com/od/fixthep... .

    Could you please give it a try and let us know if your issue gets fixed by doing a system restore?

    If the issue does not get fixed with a system restore, could you please run the DisplayLink Support Tool (instructions here:http://plugable.com/support/displayli...) and send us the .zip generated by it on the desktop as an attachment at support@plugable.com with your Amazon Order ID and a link to this thread.

    This will give us a better insight to what is going on the software side. Once we analyze the .zip, we will figure out the next steps.

  • Hi,

    Thank you for your reply. I've tried to do a system restore but I keep getting the following error message:



    I switched off my anti-virus software and still got the same error message. I will run the analysis tool and send it to you.

  • Is there any update on this. I also can now no longer use the 2 plugins that I have that gave me 4 monitors. The 2 plugable monitors seem to render applications and folder lists fine but can't seem to render information in browsers. Or rather when you scroll down in a browser window, it takes almost 20 - 30 seconds for the page to reflect the change. If I move the window to a regular monitor and back again then it displays correctly for that instant.
    If this issue can't be fixed soon then I basically have 2 plugable deadweights since most of my work is web/browser based.

    Hi Rodney,

    Thanks for posting here! Yes, the issue reported here was caused by Windows Update KB2670838. Uninstalling just that update resolves the issue.

    Here is a link to another post which also has instructions to identify and uninstall the update : http://support.plugable.com/plugable/...

    Please follow the instructions on the link. If the issue you are seeing persists after that, please do run the DisplayLink Support Tool (instructions here:http://plugable.com/support/displayli...) and send us the .zip generated by it on the desktop as an attachment at support@plugable.com with your Amazon Order ID and a link to this thread.

    We will analyze the .zip to figure out what could be causing the issue you are seeing and how to resolve it quickly.
