The ornamental design for a displayscreen with graphicaluser interface, as shown and described.
The sole FIGURE is a front view of a display screen with graphical user interface, showing our new design.
The horizontally-aligned sharp-cornered broken-line rectangle illustrates a display screen. The broken lines outside this rectangle illustrate an electronic device as the environment of the display screen. The broken lines within the rectangle illustrate portions of a graphical user interface. The broken-line subject matter, including all text and numbers shown except the plus and minus signs at each edge of the screen, forms no part of the claimed design.
