Hi Sam,

To further assist you, we would like to know what is the make and model of your HD TV? We also suggest that you check if there's an option to change the resolution through your TV.

You can also follow these steps on how to adjust screen resolution through Control Panel:

• Open Control Panel, under Appearance and Personalization, click
  Adjust screen resolution.

Lock-Screen Resolution.

My lock screen resolution is completely different then what my actual resolution is and I can't figure out how to change it? Can I even change it yet?

 

Windows 10 Taskbar sometimes on top of full-screen applications

Hi,

Thank you for posting your query on Microsoft Community.

I suggest you to change the Screen Resolution and check if this helps. Follow the steps below to do the same:

• Press ‘Windows ’ key on the keyboard.
• In the search box, type Settings
  
• SelectSystem > Display > Advanced display settings.
• Under Resolution, select a new value. We suggest you stick with the resolution marked
  "(Recommended)”.

Also try locking and then unlocking the Taskbar and check if this helps. Follow the steps below:

• Right-click an empty space on the taskbar.
• If Lock the Taskbar has a check mark next to it, the taskbar is locked.
  
• If it does not have a check mark, click Lock the Taskbar.

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.
