Permanent black bar on bottom of secondary monitor

Jorwoody · 07 Sep 2012

I installed DisplayFusion for my dual-monitor setup, but decided to uninstall it soon after. Upon uninstalling I noticed a permanent black band/bar across the bottom of my screen. I can access (right click and get a context menu, etc.) the screen space under the band, but it completely hides anything under it including the mouse pointer.

Here is a screenshot of the area and a representation of what I see:

I'm not sure if DisplayFusion could have caused this, or if it was a coincidence.

Has anybody seen a problem like this before? Any direction would be greatly appreciated. Thanks!

Welcome to Seven Forums Jorwoody. Does the black bar appear to be the height of the taskbar DisplayFusion put on the secondary monitor? If so, it seems likely that DisplayFusion is the culprit (it seems likely anyway). Do you have a System restore point from before you installed DisplayFusion? If so, I would start there.

System Restore

If not, or if that doesn't help, I would suggest you reinstall DisplayFusion, confirm the secondary monitors taskbar displays normally. I would then uninstall using the free Revo Uninstaller. See if that fixes it.

If neither help, I would run the System File Checker

SFC /SCANNOW Command - System File Checker

Let us know how it goes. A Guy

The bar is actually 10-20 pixels thinner than the windows taskbar, as I was able to see some of the top of the taskbar when I reinstalled Display Fusion. I used the Revo uninstaller and SFC /scannow but to no effect. I don't want to resort to a system restore unless I have to, because I installed a bunch of software since the last available one. The only other thing I can think to try is grabbing a different monitor and plugging it in as my secondary, and seeing if the black bar is still there. Perhaps that portion of the screen broke?

Try switching which is primary and which is secondary.

Display - Change Main Display

You might try changing the orientation as well as a test.

Problem solved... magically

I went to "Control Panel -> Appearance and Personalization -> Display -> Screen Resolution -> advanced settings for my secondary monitor

Then I clicked on "List All Modes" in the adapter tab and switched back and forth between True Color (32 bits) and High Color (16 bits). I was able to move the black bar from the bottom to the top of the monitor. Then I switched back to True Color and then I went to my NVIDIA control panel and BOOM! black edge gone. Not very scientific, but I suppose not all solutions are completely understood.

Anyways, thanks for your help! Hope nobody else runs into this problem :)

Great, sometimes we don't ask why, and are just glad it's fixed
