Se trata de una limitación de la arquitectura de gráficos intercambiables Muxless. En los gráficos intercambiables Muxless, la GPU discreta siempre depende de la GPU integrada para la salida de datos. Si la GPU integrada se desinstala o desactiva en el Administrador de dispositivos, solo quedará la GPU discreta en el sistema.
Sin embargo, sin la GPU integrada, la DGPU no puede controlar ninguna pantalla, con lo que se produce una pantalla en blanco o caracteres dañados. Si el controlador gráfico AMD se tiene que desinstalar, se recomienda desinstalarlo mediante "ATI Catalyst Install Manager" en Programas y características del Panel de control.
