The default resolution at Qt demo is set 640x480. Looks like your display has a 800x480 resolution. You should adjust it as described here - Display Output, Resolution and Timings (Linux) | Toradex Developer Center

If you are using a Toradex Display you can apply a Device Tree Overlay.

In case of future questions - please specify your display brand/type etc and full name and version of image you are using
