One of the displays there, number 1, is for the display on the computer's monitor, the other one, number 2, is for the display on the TV
You have not told use what your computer is so we have no idea what the resolution for number one display should be.
Hold your cursor over the number 2 display. If it says Not Active, RIGHT click on it and select Attached.
After clicking on the number 2 , change the resolution to one of the resolutions in the above list.
1360 X 768 or 720 X 400 will fill the TV screen the best with the proportions of width to height correct .
1280 x 768 - either it will almost fill the screen - narrow black bars on each side - or the display will be a bit stretched horizontally
The other resolutions - either will not fill the screen - wider black bars on either side - or the display will be stretched a lot horizontally
(see View mode pages 39, 40 of the manual)
Click on OK at the bottom of the Display settings window to make the display on the TV change if you changed the resolution.
