Windows 10: Row of flashing pixels on the bottom of taskbar that mirror the top of the screen

I recently got a laptop with Windows 10 and there's this weird row of pixels that flash sometimes on the bottom of the screen. They sometimes don't flash, sometimes they do, and a lot of the time they disappear completely. Does anyone know what's causing this?

I already updated my display drivers. Not sure what other things I can check.

the top row is not working

Hi,

Thank you for posting your query in Microsoft Community.

To better understand your query, please reply:

1. What do you mean by "top row not working" not working? Are you referring to keyboard top row keys?

I would suggest you to go to the safe mode and see if the problem persists.

To go to Safe mode follow the steps below:

• 
  Click on Windows key, and in the Power Options click on Restart while pressing the shift key.
  
• 
  A blue screen will appear with a few options.
  
  Click on Troubleshoot > Advanced Settings > Startup Settings > Restart.
  
• 
  Your system will automatically restart, press 4 or F4 key to go to the Safe Mode.
  

Awaiting your response.

Regards,

 

How to hide the taskbar on the top row of screens only in Windows 10?

I have a quad-monitor setup (two stacked rows of two monitors) and a PC running Windows 10.

Problem

It's really annoying having a taskbar on the top screens as it cuts through the windows I have extending my vertical screens.

I've tried multiple configurations of the taskbar settings, but it doesn't seem to support this specific setup. I'd like to have the taskbar display on only the bottom two screens and hidden/disabled on the top two screens.

The closest I can come to this setup is having the taskbar only show on my main display or put the taskbars in auto-hide mode. While these somewhat work, I find it quite annoying switching between windows with auto-hide or having the taskbar only shown on my main display (breaking my neck every time I need to switch windows on display 1).

Notes (relating to image below):

• Main display is display 4 (highlighted in blue)
  
• I want the taskbar on displays 4 & 3 (as indicated with the green boxes)
  

Question

How can I show the taskbar on only the bottom two screens while having it disabled or hidden on the top two screens?

 

How to keep Windows 10 taskbar on top all windows

FIXED for me - I noticed the bottom few rows of pixels were missing off the bottom of the screen. The mouse was stopping at the last row of pixels, not disappearing down to where the taskbar would be. There was apparently a problem with my screen resolution
or registration.

I changed my screen resolution, then changed it back to the recommended setting (native resolution) and my taskbar is now accessible.
