Is the line on your physical monitor, or as part of your wallpaper? If it's just wallpaper, use the Windows wallpaper utility to change your wallpaper.

Most likely unrelated to DisplayFusion.

The problem is probably in the display driver. You may have to upgrade the driver to a version newer than the auto-update version on Windows Update. On a laptop, you may also have to update the BIOS. In some cases, you may even have to downgrade the driver instead, to an older version before the bug was introduced. In that case, you will need to turn off automatic updates for drivers.

If you're really unlucky, it'll be the hardware. But most of the time, it's the driver. I've seen display drivers cause all sorts of problems: a vertical line (mine was green), junk on the screen, parts of the screen turning black, flickering in window refreshes, etc. Display drivers are the most unreliable part of a modern computer system.

@taoyue: These were my thoughts as well.

If the line is on your physical monitor, it sounds more like a hardware issue, sorry. :(

I'm not that techy enough to play with driver update selectively. It's new laptop, so I just did a disk recovery to bring it back to factory status. Plus is that the blue line is gone, but minus is that I'm not sure about the root cause..and whether to have DF pro on again..

Well if anything, you can try it again. If it DOES come back up, you already have a reliable way to fix it. If it DOES come back, please inform us of the make, model, and any special hardware or software you have, I would personally like to inform the developers of the issue.

I would be interested to know if the blue line does return with DF installed, but if you don't want to chance it I understand as well. However, I can safely say that no one else has ever reported an error like this, and I don't think DF could cause your monitor to have a blue line across it.
