Severe screen flashing on 7.4M0

euitdebos · 09-23-2013, 08:13 PM

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,

Which of the issues mentioned here are you seeing?

Thanks,
James

What I am seeing is just the screen flashing. Ethernet stays connected.

I have noticed some patterns, maybe they are correct, maybe not.

I have a setup on my desktop where I have one big 24inch monitor that I share using an ATEN KVM switch between my laptop+Dock and my Desktop-PC. Whenever I switch from Laptop+Dock to KVM and return to the Laptop+Dock after a while, the screen flashing is much more severe.
The ATEN KVM switch connects/disconnects the USB+MOUSE+Monitor from the Laptop+Dock, because I can hear the "USB Connection" beeps that Windows makes, whenever I switch.

Hope this helps
