Flashing Screen..Win 7

[jabbiati]

Support...plz help. I just swapped out an older Dell Win7 machine with a new Dell M6800 with Win 7. Didn't have any problem with Displayline before. Now my screens flash off and on every five seconds. I've gone through the forum and checked everything... drivers, cables, changing ports, etc.

Here is the compat check:

Pass: Basic mode support
Pass: Device attached
Pass: Device started correctly
Pass: Graphics driver date
Pass: WEI is above recommended 3
Pass: No Other USB graphics software installed

Attached is the ZIP.

It seems that sometimes I can reboot and everything is fine. If I change anything in monitor management, the blinking starts again.

When I reboot, the can stop the screen flashing, but the attached USB drives will drop off and on intermittently...

This sounds like a USB issue? Is the dock appearing and disappearing in device manager when this happens?

I think this is the latest driver for your USB 3.0 host controller:

Yeah I think so too.... thanks for the link. I've had other issues now, so now I'm gonna do a restore and try this again.

No luck... installed updated USB3 driver. Reinstalled Displaylink driver... still flashing screens.

Is the dock appearing and disappearing in device manager when this happens? Need to diagnose which part of your system is causing the screens to flash

Wim...I just ran the Dell Update manager and despite cust support's word, I had a slew of things out of date, including the BIOS. At the moment things seem to be working, but if it recurrs I will check the device manager and repost.

Thanks for the help.
