Customised Windows 10 lock screen resolution?

[Sonic007]

I’m setting up my group policies to set a custom Windows lock screen but just wondered what others have set their background picture resolution to?

 

We have a mixture of 13” laptops and then mostly 65” Interactive TV computer screens.

 

What sizes have you used?

 

Many thanks.
