DVI-D to HDMI problem

alphanumeric · 21 Aug 2016

Do you need a dual link DVI cable in this case? Since the source is HDMI? Single link DVI cables are minus a few wires.

EDIT: If the cable is all one piece, with no other adapter on the end, it likely doesn't matter. All the wires should be there for full functionality..

Screen shots done with the snipping tool might help.

DVI does not have audio. HDMI does, but DVI doesn't. If your source is a DVI there is no audio signal. Not if you follow the specifications for DVI. In my case its HDMI to my monitors DVI. The audio part of my HDMI signal goes no where. It dead ends at the HDMI to DVI adapter on my monitor. I use PC speakers so its no big deal for me. I've just never heard of anybody doing it the other way around, DVI to HDMI. Just wondering if some wires get crossed up going that way. Of it a signal is lost?

DVI supports audio in a DVI-to-HDMI -cabling, not the other way around (incase youd need HDMI-audio de-embedder, which no blank HDMI-to-DVI -adapter supports).

According to the specification for the DVI interface, there is no audio in a DVI signal from the video card. DVI is video only. There can be an Analog Video signal and a Digital Video signal, but there is no audio signal.

If all you have is a passive adapter or cable, you will not get any audio at the HDMI end of the cable. That's all I'm saying. It's not relevant to the problem at hand anyway.

metrognome, when you switch to HDMI on the monitor, make sure the PC is in "PC Screen Only Mode", Windows logo key

+ P > PC Screen Only. Just to make sure your PC isn't accidentally detecting your one monitor as two monitors. Or unplug the VGA cable.

nvidia gtx 470 for example delivers audio via DVI-to-HDMI - one more case of wikipedia not giving out the full facts. but yeah whatever, its a bit offtopic anyway

Yea! That did it. Thanks alphanumeric.

Mystere hit on it earlier. It was displaying like it was the second monitor in a dual monitor setup. With both cables connected, and the monitor on, The PC thought there were two monitors connected. You should be all set now.
