Question Why doesn't my taskbar extend completely across the full width of my screen ?

[NoGagMaestro]

I have my pc (Win 11) hooked up to my 4k monitor via DP and my 77" 4k Oled via hdmi. Both are set at 2840x2160 (4k) display. The recommended scale setting for the tv is 300% while the monitor is 150%. When I first hooked up the pc to the tv the taskbar filled the bottom of the screen but now it will start like this and if I want it to fill the bottom of the screen I have to change the scale setting and then change it back to 300%. If I switch the input to a different hdmi and go back to the pc input it reverts back. Anyone know what would be causing this issue?

Welcome to Windows 11. The new task bar does not cover the entire width of the screen by default.

You can get most of the old task bar back (at least until this is again removed)

That's not the issue. The taskbar stays full width on my desktop monitor but not on my TV unless I change the scaling from 300% and back to 300% (the recommended setting). Maybe I'm misleading about what I consider to be the taskbar, the whole bottom bar not just the Windows start icon on the taskbar. If you look at the last pics compared to my first picture you can see where the bar is centered and then it fills the very bottom of the screen. Thanks for your reply.

The issue you're experiencing with your taskbar not extending completely across the full width of your screen on your 4K TV seems to be related to a combination of factors, including the scaling settings and the switching of HDMI inputs.

Windows 11, like its predecessors, has had some issues with high-DPI scaling, especially when it comes to mixed monitor setups with different resolutions and scaling settings . This can cause inconsistencies in how elements like the taskbar are displayed.

When you switch HDMI inputs and then return to the PC input, it seems that Windows is not correctly remembering the scaling setting for the TV, causing the taskbar to revert to a smaller size. This is a known issue with Windows 11 and changing inputs on monitors.

A workaround that some users have found is to adjust the display resolution and then revert it back to the original setting. This seems to temporarily fix the issue, but it's not a permanent solution.

Another potential solution is to override the high DPI scaling behavior for specific applications. This can be done by right-clicking on the application, selecting Properties, going to the Compatibility tab, clicking on "Change high DPI settings", and then checking the box that says "Override high DPI scaling behavior. Scaling performed by:" and selecting "System (Enhanced)" from the drop-down menu.

However, it's important to note that Windows 11 does not currently provide an official built-in option to resize the taskbar. Any changes to the registry to attempt to resize the taskbar are not recommended, as they can potentially cause system instability or other issues.

Microsoft periodically updates Windows, and it's possible that a taskbar resizing option or a fix for this issue may be introduced in a future update. In the meantime, it's recommended to keep your system updated and to monitor official Windows updates and announcements for any changes or new features related to taskbar customization in Windows 11/

Thank you. This explains my issue quite well. I was looking for a fix to having to adjust the resolution and revert it back each time. I though it was a me a problem but it's a win 11 problem. I guess I should've stayed on 10 lol.
