I'm trying to get a Chromecast to work on a Dell 1907 FP monitor I have. I originally used an HDMI to DVI-D adapter. The Chromecast starts and shows it's start up screen. Then everything goes black. I can connect to the Chromecast with my IPhone but there's no picture. Is there anything I can do in the settings or should I try another adapter? like the HDMI to VGA connector? Please Advise.
