    VGA to DVI to HDMI to USB

    Alec Dalek

    Won’t work. For starters, VGA requires power from the host. USB provides power, but HDMI does not. And that’s before you get into sync issues. And DVI to HDMI adapters don’t provide an analog signal which the VGA would need.

    Soong

    Pardon, but DVI-I and DVI-A (which I’ve never seen) both provide analog output. That’s why for about 10 years video cards came with, and I suppose many still do, DVI to VGA adapters.

    Standard HDMI does not provide analog output but an active converter can be used; usually larger than what’s pictured. The thing that makes no sense here is an HDMI to USB adapter. I’m thinking it might be HDMI to micro-display port.

    A DVI adapter connected to an HDMI output will only provide DVI-D output. To get an analog signal, you’d need a converter. So the chain of adapters in the picture wouldn’t work.

    it’s going from digital to analog, I’ve used all those adapters individually, so I see no reason for them to suddenly stop working when used togther.

    hell I think I’ve used 2 of the adapters in there at the same time, the HDMI to dvi to vga.

    You can go from HDMI to DVI-D, and you can go from either DVI-I or DVI-A to VGA, but you can’t go from HDMI to DVI-D to VGA without a converter. You would need a converter to go from HDMI to DVI-A (Analog) or DVI-I (Analog and Digital), which you could then connect a VGA adapter to. An HDMI connector can only provide DVI-D output with just an adapter. You need a converter to produce the analog signal that would then be needed by the VGA adapter.

    is this something new? cause I’m telling you, I’ve done that myself before. you’re saying that the DVI adapter would be useless in any situation if I’m reading your right.

    I believe you’re incorrect in your assertion that the HDMI adapter wouldnt’ put out an analog signal, google has a million of them out there that do just that: www.google.com/search?q=hdmi+to+dvi-i

    Those would be used to connect a DVI-I source to an HDMI display.

    VGA -> VGA-DVI -> DVI-HDMI -> HDMI-MiniDP ?

    Alec Dalek

    Can’t really see what device it’s hooked up to, but it could be either mini-DisplayPort, mini-HDMI, MHL, or even micro/mini USB.

    Yup, also thought of mini\micro USB, but discarded it since it’s “brilliant” in that configuration.

    Alec Dalek

    A Micro USB port can support HDMI in some instances, such as a Samsung Galaxy S4 with their HDMI adapter.
