We are trying to extend the screen of a Windows Surface Book to a large TV screen and can't get the settings exactly right so that none of the icons are cut off on the TV screen.
We are going from HDMI through this USB-C adapter https://www.amazon.com/gp/product/B07THJGZ9Z/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 to the USB-C port on the Windows Surface Book.
I looked up aspect ratios for TV screens and came up 16:9 for the aspect ratio of most newer HD TVs.
The best resolution for us corresponding to that aspect ratio seems to be 1280x720, but we are still cut off.
I have since found out that the TV is an AQUOS with an unknown (presumably model) number found in the menu of 211U1412121. It looks more like a serial number to me but the menu did not specify the model or serial so I suppose I can be hopeful. The screen size is still unknown.
What am I missing?
How can I resolve this?
