Toshiba USB Monitor flickering

[k1troutman]

I have a IBM T520 fresh out of the box today. Win7 64bit, SP1 and I just updated the latest video drivers as well.

I have 2 Display Port's and upon plugging in either on the main screen turns black and the cursor blinks rapidly. You can move the cursor around and it work but can't see anything.

The port being plugged in will light up the led on the Display Link adapter but the monitor never receives a signal to warm up the monitor and take it out of standby.

I know both of my display links are good as I can connect them to my old IBM T61p running XP 32 bit and they work perfectly.

Here is the support files as requested in a previous user with both Display Link's plugged in within a minute of each other.

Thanks.

Hi,
I am having similar flickering issue as exposed by Wim and Sloo1. I installed a Kensington sd-400v on a Dell XPS 15z and connected a NEC MultiSync1770NX monitor to it. The installation apparently went well but only lasted for couple minutes and the second monitor went blank. When I rebooted and every time I attempt to connect again with the monitor plugged in, I get a flickering screen on the laptop, blank screen on the monitor.

Connecting the DisplayLink device without the monitor plugged in works ok, but that is not the point for me of using this device. I installed latest drivers from DisplayLink website, repeated the installation with the same results.

I will appreciate if support can be provided to fix this. Attached the log files.

Hi

I think you have the same problem with NVIDIA graphics that we're trying to track down at the moment, but you are also trying to use this with the Kensington sd400v. The auto install on this dock does not work with v5.6 software or later, so you will need to use v5.5 from the Kensington website.

We're working with Kensington to solve this, to allow the latest versions of software to be used with the dock, but this is not available yet.

Thanks

Could we please get an update on this? Is this an nvidia problem or a problem with the DisplayLink drivers?

Thanks for your help.

There seem to be several different reports of problems on NVIDIA, but not much correlation between GPUs and NVIDIA driver versions. We have reproduced one of the blue screens experienced on a GeForce GT 540M which may cause other symptoms.

We're looking into a fix for this and hopefully it will fix some of the other NVIDIA issues found.

Any updates regarding this problem?

I cannot use Nvidia drivers and therefore cannot use my computer to its full potential.

Thanks!

I also am having the same flickering issue that follows the blue screen upon initial connection. I have updated the latest nvidia chipset drivers for the NVS line as well as pulled the latest driver from Toshiba's website. Same issue. Black screen with a flickering cursor.

The laptop is a Dell Latitude E6520. The screen works fine with Dell's Intel HD gfx chipsets.

Any updates on the patch status?
