.. _display_resolution:

=================== Changing Resolution

To set the resolution of the display after creation use :cpp:expr:lv_display_set_resolution(display, hor_res, ver_res)

It's not mandatory to use the whole display for LVGL, however in some cases the physical resolution is important. For example, the touchpad still sees the whole resolution, and the values need to be converted to the active LVGL display area. So the physical resolution and the offset of the active area can be set with :cpp:expr:lv_display_set_physical_resolution(disp, hor_res, ver_res) and :cpp:expr:lv_display_set_offset(disp, x, y)
