Foi mal, nem olhei ...kkkkkk confundi vc com o autor da duvida...abraços

Eu sei irmão, mas isso depende de uma rotina bem mais detalhada antes de chavear esse 3v, se esse for o defeito se vc chavear direto tem que funcionar Acredito que seu problema é outro. falei pra ver monitor externo pra vc talvez eliminar o defeito!.

Bom dia irmão, primeiro faça um teste pra verificar se tem video externo! antes de mais nada
