I bought the converter to connect a Dell laptop via the HDMI port to an old projector with VGA. When "Switch" on the laptop, however, forever came out no proper picture on Beamer. The quality of the conversion of HDMI to VGA was great, but the format was not right. Eventually, it was enough for me and I just pulled out the converter cable at the official and reingesteckt again. And at once the laptop has automatically responded and the officer worked. My experience: the fault lay not in the converter but the settings on the laptop.
