Severe screen flashing on 7.4M0

[rsenio]

Agree....one issue after another. I just updated to 7.4 yesterday. Today....one screen "dimmed" to almost black and went super blocky every time I was dragging and dropping email within my outlook. Also....Internet Explorer no longer works, LMAO. I can open it....hit control-o and type in an address to go to and then it just sits there. It doesn't go unresponsive, but you can no longer click anything in I.E. If I undock, I can use I.E like normal. GREAT UPDATE guys!! First, and most importantly LAST displaylink device I have in my office environment. I couldn't imaging my users dealing with this garbage.

Hi,

To help us investigate the issue with IE, please download this tool:
http://www.displaylink.com/support/ticket.php?id=269

As soon as the issue with IE is seen again, please run the tool and select "Gather Support Information".

It's also worth trying the "System Compatibility Check" to see if anything is flagged up.

Thanks,
James

Hi,

Regarding the issue with flickering - I've reproduced this myself but I don't have clear steps to reproduce. Sometimes it happens, sometimes it doesn't.

Do any of you guys have a set of steps to reliably show the flickering every time?

Thanks,
James

Generally for me it happens when using the internet.

Bigger problem for me is the disconnection issues. The dock will lose connectivity consistently throughout the day. We use a number of cloud services so this is a big problem.

I can get around this by using the wifi instead of the dock, but then why did I pay for a dock if this is the solution?

Hi,

The support files tell us that there are usb connection errors which will cause the ethernet connection to drop.

Can you check if you have the latest hub firmware programmed?

Open up device manager, open up Universal Serial Bus controllers and right click on the entry called “Generic SuperSpeed USB Hub”.
Select “Properties”, select “Details”, change “Property” to “Hardware Ids” and the REV_xxxx value will tell you what version of firmware is programmed on the hub.

Let me know what revision is reported.

I'd also suggest trying another USB cable & other USB ports.

It's also worth trying the "System Compatibility Check" option in the DisplayLink debug tool to see if anything is flagged up.

Thanks,
James

I have since uninstalled and gone back to the previous version. I am unable to provide YOUR troubleshooting for you, my laptop needs to work....for work. Sorry.

I have this as well, mostly it seems when I'm doing a lot of stuff at the same time.

What seems to help is to disconnect, wait a couple of seconds, then reconnect the dock. I In my case it is a Kensington SD3000 connected over a USB 2.0 cable to a Dell 6430u Laptop with Win7x64. USB 3.0 cables don't work, except for a brief moment when I was de-installing the DisplayLink SW to do a clean reinstall. Somewhere during the installation process a USB Driver gets overwritten that causes my USB3 to fail.

Hi,

Just to keep you updated - the issue with flickering is currently under investigation as we've found a reliable way to reproduce this.

I'll post an update again when I know more.
