I can't see anything obvious wrong in your log, and this is different to LimboMan's issue. Can you see if v6.3 fixes it, and if not, repost logs with 6.3 installed.

Wim

Thanks for reviewing my file. While what you had assumed may be true, I had absolutely no problems using my set-up under Windows XP. That's why I was so disappointed when moving to Windows 7 to find that I couldn't use my monitors together.

Any workarounds, fixes?

log file
 

this is my log file with 6.3.

now my laptop screen keeps flickering.....still i can't see anything on my extended screen.

Can you be more descriptive about the flickering? Do you need to change something on the screen to cause flicker? Does downgrading to v6.2 solve it?

Wim

Same problem, FIXED!
 

Hey, I just registered so I could provide a possible solution.
I am running a Startech USB2HDMI Displaylink adapter.
I had been running it for 3 weeks without issue from a dell Vostro workstation, using two USB ports in the back, on the motherboard.
I did a microsoft update, and after a reboot, the device was no longer recognized. It just showed up as a generic USB host or something.

For whatever reason, I am not getting sufficient power...But I was before.
I plugged the power only part of the supplied USB cable into my iPad USB charger, and it recognized it immediately.
Now its running.
Just thought I would share my experience.
I hope your issue is just as easy to fix.

how to stick with old versions of disply software.
 

hi, Wim.
Before i upgraded to v6.3, i couldn't see the screen. Now i can. i can see the screen but it keeps flickering. one moment is off and the next moment is on, then again and again..... i managed to make the log file, because i could see icons on the screen during that "ON"-time. but no one could see the screen no more that 5 secs. Eyes would hurt.
it's quite descriptive???
the thing is that i could see the screen just when i installed display link from the little DVD from the package, but then windows 7 will update it straight away to the newest version.
i want to stick with the old version from the DVD. Any solution to that???

Can you post the log file. I think I might know what the problem is, but want the log file to check before I guess.

Wim

my logfile...
 

There you go,,,my logfile again.
i hope you can find a real issue this time. it's been a long while.
Thank you.

Does this mean that I can only use both of my monitors under Windows XP then? I should try to sell my other monitor? Is there any chance for a fix or work-around?

Thanks for the logs. This does look strange. The log shows that we are receiving lots of mode change events from the OS from an "unknown process" (which means the task ended before we could find out what caused the display change event). It looks like there is some 3rd party software trying to manage your display layout and desperately trying to change the desktop layout, which is causing lots of events in our driver and not surprisingly flashing the screen.

I've never seen this before so I don't know for sure what is causing it. However could you try disabling the NVIDIA service and see if this helps? If not, do you know of anything else you have installed that could change display settings? I see you have many programs installed.

Thanks

Wim

How do you check the serial number in device manager. I have 2 identical monitors and 2 identical adapters and can't get them to both work consistently. One always randomly flashes black screen and then eventually goes black

They wouldn't work at all if this was the problem. If they are randomly flashing black, do you have the adapters connected to an externally powered hub? Sounds like the adapter may not always have enough USB bus power to keep working.

Wim

Yes. They are both plugged into a brand new external powered usb hub.
If that is the problem would a solution be to switch to a better usb hub.

I currently have plugable 10 port hub (using 6 ports) which is plugged into a new surge protector that has no problems with any other item connected to them.

thx for reply
