I want to duplicate my screen on a TV via hdmi (1080P)
I can not get my TV in full screen mode and i can not adjust the resolution in windows 10 for my tv
Is there a way in windows 10 or can i download software to do this

This cannot work. You'd need the same resolution on both, but your TV will not upscale HD 720p to full HD, sorry.

But when i use the screen in extended mode i have full screen, is there no way to adjust the second screen in windows 10 with duplicate screen?
Will this be the same if i use a computerscreen with hdmi?

Thanks for your help Danny

When duplicating, both displays need to use the same resolution, and since it needs to work on both it will use the lower resolution of both displays. When you extend the display, it doesn't need to do that, as then the displays are separate from each other and don't need to use the same resolutions. So in that situation each display will use it's optimal resolution, provided the video cards supports that.

If you use a laptop that gas a resolution of 1920x1080, then you would be able to use the full resolution of the TV or external display of 1920x1080 too, if you clone the displays.

You can also check the settings on your TV. Some have options where you can stretch what is displayed to make use of more of it's area.

You want to use your touchscreen, that means, both, the internal display and the tv need to be at the same resolution. That is not possible in full screen unless your tv would switch to HD720p, which it obviously does not do.
If you use another (computer-) screen, it might do it, normal monitors let you run other resolutions than their native ones as well.

Edit after Rindi's comment: yes, you might want to explore the options of your tv to stretch content.

No problem, I just try to explain it a little different to make it clearer.
