Не удалось установить разрешение API QueryDisplayConfig/SetDisplayConfig. ⇐ C#

[Anonymous]

При использовании API QueryDisplayConfig/SetDisplayedConfig для изменения разрешения экрана независимо от операции возвращается код 87. Я не могу знать, что стало причиной этого. Я использовал метод размеров буфера VNet DisplayedConfig, но мне все равно не удалось
