Hi Mirthology, and welcome to TSG.
Are you able to get into the Windows 10 Display Settings (right click on an unused area of the desktop) and adjust the output resolution to exactly match LG flatscreen's native resolution? If not, you might need to set a lower resolution that will fit on the screen, but will have some black borders with 0% scaling.
