Black screen

Rick Eveleigh · 07-01-2013, 01:54 PM

Dell Inspiron 7720SE, external monitor is Samsung SyncMaster B2230HD. All working on Windows 8 before applying 8.1 upgrade (64 bit).

Got latest drivers for NVIDIA & Intel graphics as applied by Windows Update after the 8.1 upgrade.

Installed the v7.4 beta but the external monitor is black, but 'alive': I can drag windows off to it but they disappear.

I have attached the diagnostic report.

Came in this morning and my external monitor now works. No idea why!

Came in today now not working again, same issue -- screen is 'alive' but is black -- I have it on extended desktop and I can drag windows to it but they don't show. All updates are applied.

Do you need the diags again?

Also in Device Manager the driver version for the Targus USB Video is DisplayLink 7.2.47873.0. I thought it should be 7.4.48853.0, same as the version in Add/Remove Programs.

Hi,

When this happens can you try the following?

Restart the DisplayLink service
- bring up the metro screen
- type "services"
- select Settings
- view local services
- select DisplayLinkManager
- select restart the service

Thanks,
James

I assume you mean DisplayLinkManager service?

When I restart it (I do Win+R and type services.msc), the extended screen does the same as the fault -- it shows 'PC 1920x1080' for a few seconds which shows it is 'live' but it remains black. Occasionally when trying things you see the cursor duplicated to the screen but not anything else.

Is the driver version not being 7.4.x what you would expect?

Thanks

Rick
