Cropping my Display

In addition to M3tal Daz3 suggestion it may also be worth checking the settings on your television as some models offer a zooming feature that may have been activated.

If the Xbox 360 detects that the display supports PC resolutions over HDMI and that the display's native resolution matches one of those, it switches to that. An advantage of this is that your display will treat the picture the way it would that from a PC,
and show it without cropping. With video resolutions, TVs normally crop 2.5% or more from each edge.

So called 'native 720p' TVs usually have a panel resolution of 1366x768, so they are not literally 720p. Some smaller TVs may use panels designed primarily for PC use, and have different panel resolutions, such as 1440x900. Manufacturers and retailers often
label those as 720p to indicate that the resolution is below that which they call Full HD, 1920x1080.

The Xbox 360 does a fairly good job at scaling the picture, since its scaling methods are chosen and tweaked for handling graphics.

There would be a delay introduced by the capture card making playing very difficult.

If you want to spread out the picture from the Xbox One across the monitors, remember that it would need to crop 1/3rd off the top and bottom, which is far greater than the 'action safe' and 'title safe' areas assumed for console games and video. They're
designed assuming only 5-8% of each edge may be cropped by the display.

If you don't mind me asking, what is the goal of the setup?

Hello, well I checked the settings but I didn't found anything related with my problem of cropped screenshots
