Hi,

Please try the latest graphics driver for your HP notebook available from this link:

Also can you let me know if this issue persists after upgrading to v7.9M3?
You can download this from here:

Thanks,

Hi!

I have tested the latest driver for both the laptop and the displaylink adapter without success. I ran the support tool once more so that you have fresh data.

Any news on this?

Downgrade to resolve flickering
 

As an FYI, I had a similar problem and downgraded to M3 that solved the problem. Steps taken:

- Disconnect USB
- Uninstall software and graphics entry in Control Panel
- Reboot
- Carry out Clean Uninstall (http://www.displaylink.com/downloads/file?d=64)
- Install M3 version
- Connect USB when asked
- Reboot.

Hope this helps.

Did you have these problems prior to M4 as well? I have had them since 7.9 M0 so it sounds strange that it could be solved by downgrading to M3 but I can give it a try.

Hi

I've just looked at this video and this looks like a hardware problem; specifically the memory in the dock, used to hold the video frame buffer is faulty. It does not look like a driver issue.

Flickering/Freezing Display - Solution
 

I had the same issue where my computer was unusable when hooked up to the dynadock due to flickering. I tried this solution on the hp forum and it actually worked!
" NualaMa 18:21 PM 06 Aug 15 There is a simple fix

Open task manager ...
under file (top left) "Run new task" ...
type msconfig (yes it is hard to type as screen blinks, but it can be done) ...
In the new box that opens (it may be behind the task manager box) go to Service Tab ....
Scroll until you find 2 tasks that need to be stopped ...
(1) Problem Reports and Solution Control Panel Support ....
(2) Windows Error Report Service.... Disable these by unchecking ....
Click Apply ...
Click OK ...
If you are prompted to restart, then restart computer .....

This is the main issue causing the screen to blink . .. Ironic that the items causing the errors are the solutions designed to report errors to microsoft"

I have no problem with the laptop screen, only with the external screen. Was it the same for you?

I have tested this on another HP 3005pr replicator with the same result som hardware problem doesn't seem to be the case. My colleague uses that replicator with another HP laptop (although another model) without problems.
