Windows 10: A toolbar is already hidden on this side of your screen. You can have only one auto-hide...

I am randomly getting this notification/error when I wake up my PC monitors, or my PC in general. If seemingly refers to the toolbar on display which is set to primary. And I have to press OK every time and set the toolbar to automatically hide again, every time. This is super annoying and frustrating.My setup is following:- TV is connected via HDMI, hence is always considered to be connected and is always seen as a third display even when it's off;- LG monitor connected via DP, time to wake-up 2-3 seconds, no Deep Sleep configuration, so when it goes to sleep, Windows thinks that the device i

A toolbar is already hidden on this side of your screen. You can have only one auto-hide toolbar per side

I have tried to resolve this issue with Windows support but they have no solution so far and the months pass by... so I would like to try here and see if some smart member(s) on Superuser can help me out!

I have an Acer laptop with 1 TV and 2 external monitors connected. (4 screens in total, laptop internal, 2 external and TV). The TV is connected directly via the laptops HDMI and the 2 external monitors are connected via an USB hub with its own gfxcard.





I have the internal laptop monitor set to "Disconnect this display" while the others are connected. The internal display is only used when all other monitors are disconnected. So I use 3 screens, the 2 external monitors and the TV. Like in the image below:





These are not my screens, just a pic I found on the web to describe the setup.

ISSUE:

I get this popup with error message in Windows 10 every time I turn off or on the TV, I it have connected to my laptop via HDMI.

A toolbar is already hidden on this side of your screen.
You can have only one auto-hide toolbar per side.





This is what happens:

When I either turn on or off the TV the other monitors flash and I hear the the blip-blop sound of disconnecting a device. Right after it happens the taskbar that I have set to Auto-Hide is suddenly popping up, is visible and does not hide again. This is irritating because I like taskbar to always Auto-hide. But most irritating, a warning sound and a popup appears with the error message:

A toolbar is already hidden on this side of your screen.
You can have only one auto-hide toolbar per side.

My TV turns itself off after a while to save energy and PLOPP I get the fricking popup again. Often in the middle of doing something that gets interrupted until I click OK on the popup.

I have tried searching internet for a solution or for someone with same or even a similar problem, but incredibly I could not find anything at all related. The issue is extremely irritating because I turn on and off the TV several times every day. And each time I have to close the popup and then enter taskbar settings and change it back to auto-hide.

To make things even worse the popup with the error message is sometimes showing only on the turned off TV connection so that I have to turn on the TV again and click OK on the popup to be able to access the taskbar at all again.

I got a few replies from a guy at Microsoft with suggestions, but nothing that worked or was even close to work, you can read it here: https://answers.microsoft.com/en-us...essageId=ca5d7e4b-c274-4932-a236-4e2b3a927483

I would very much appreciate any help in this matter as it is slowly driving me crazy...

Thanks in advance!

A toolbar is already hidden on this side of your screen. You can have only one auto-hide toolbar per side.

I have tested Method 1 (Turning off all notifications) and I still get the irritating popup with the error message "A toolbar is already hidden on this side of your screen. You can have only one auto-hide toolbar per side." so that did not work.

I dont think this popup is a normal Windows 10 notification. It looks more like some remnant from XP times. If I search for "toolbar" in Windows 10 settings nothing at all comes up.

Still there is this:

that comes from this old thread Problems with floating toolbars from 2011

Problem is that the way you configure taskbar in settings now there is no toolbar settings at all.

Edit: found toolbars in Win 10, rightclick taskbar and choose toolbars at top of menu. I have none selected to show so not sure what the problem is.

I guess I have to try method 2 now...
