    Hey guys, it was a long time since I needed assistance with any technical stuff but today is the day again.

    So it is like this,
    I am using an Asus N61JQ laptop and I always used the VGA cable to connect any monitor or projector. Today I wanted to connect my laptop to my Dell U2412M monitor with a digital cable instead of VGA and that is when got in to problems.

    Dell U2412M connections: DVI, Display Port, VGA.
    Asus N61JQ connections: HDMI, VGA.


    To connect the laptop to the monitor I have used an nVidia adapter that came along with one of the GPU's + an 1.8m HDMI cable.
    This is the link to the adapter: http://www.ascendtech.us/mmASC/Images/P331X.jpg
    So I connected the adapter to the monitor and then the HDMI cable from the laptop. In the end I did not get any image.
    Just to be safe I have also installed the original drivers for the GPU and audio chip from Asus support.
    The cable is not faulty nor is the adapter, tested it on an old laptop that had DVI on the side of it.

    Question:
    WHY? Something to do with the signal conversion and it suppose to work just from the back of a GPU?
    What kind of an adapter or cable do I need then?

    PS,
    I do not really want a big adapter sticking out of my laptops HDMI port, it is way too easy to break. But please include both the adapter and the cable that I need in the explanation just so I know this for the future.


    Thank you for your time.

    Alex

    Faulty/incorrect adapter. Try a different adapter or use a DVI to HDMI cable. It's also possible that it won't work at all. The adapters are generally meant to connect to the PC side (ie: DVI output). This is because most HDMI ports also expect/utilize HDCP.

    The adapter works, like I have said I have tasted it on another laptop that has a DVI connector on the side instead of HDMI or VGA.
    Incorrect adapter - might be so, but then how do you define witch is the correct one?

    Sadly I do not have such a hybrid cable ATM.

    From what I have seen the adapter works if it is connected to the motherboard or GPU but does not if it is on the monitor side, was wondering why? Is it because the signal does not go through correctly (I thought it might be to the fact that HDMI tries to transfer audio as well, but I have heard that some DVI ports can also do that these days, so I do not think that is the case)
