fatal error: Arduino_H7_Video.h: No such file or directory

Hi, i have a Arduino GIGA with the GIGA Display Shield. I want to learn to use the Display, so I looked at the Arduino website. There is an example how to start with the display.
I installed: the GIGA Boards (Board Manager) and these librarys: Arduino_GigaDisplayTouch and lvgl (both from the Arduino library).
But if I want to verify my code this error is showing:

\NewTouchDisplay\NewTouchDisplay.ino:1:10: fatal error: Arduino_H7_Video.h: No such file or directory
#include "Arduino_H7_Video.h"
^~~~~~~~~~~~~~~~~~~~
compilation terminated.
exit status 1

Compilation error: Arduino_H7_Video.h: No such file or directory

(I followed every step of the example.)
This error is with all librarys. Can someone help? Thank you very much

My Code:
#include "Arduino_H7_Video.h"
#include "lvgl.h"
#include "Arduino_GigaDisplayTouch.h"

Arduino_H7_Video Display(800, 480, GigaDisplayShield);
Arduino_GigaDisplayTouch TouchDetector;

void setup() {
Display.begin();
TouchDetector.begin();

//Display & Grid Setup
lv_obj_t* screen = lv_obj_create(lv_scr_act());
lv_obj_set_size(screen, Display.width(), Display.height());

static lv_coord_t col_dsc[] = { 370, 370, LV_GRID_TEMPLATE_LAST };
static lv_coord_t row_dsc[] = { 215, 215, 215, 215, LV_GRID_TEMPLATE_LAST };

lv_obj_t* grid = lv_obj_create(lv_scr_act());
lv_obj_set_grid_dsc_array(grid, col_dsc, row_dsc);
lv_obj_set_size(grid, Display.width(), Display.height());

//top left
lv_obj_t* obj;
obj = lv_obj_create(grid);
lv_obj_set_grid_cell(obj, LV_GRID_ALIGN_STRETCH, 0, 1, //column
LV_GRID_ALIGN_STRETCH, 0, 1); //row

//bottom left
obj = lv_obj_create(grid);
lv_obj_set_grid_cell(obj, LV_GRID_ALIGN_STRETCH, 0, 1, //column
LV_GRID_ALIGN_STRETCH, 1, 1); //row
//top right
obj = lv_obj_create(grid);
lv_obj_set_grid_cell(obj, LV_GRID_ALIGN_STRETCH, 1, 1, //column
LV_GRID_ALIGN_STRETCH, 0, 1); //row

//bottom right
obj = lv_obj_create(grid);
lv_obj_set_grid_cell(obj, LV_GRID_ALIGN_STRETCH, 1, 1, //column
LV_GRID_ALIGN_STRETCH, 1, 1); //row
}

void loop() {
lv_timer_handler();
}
