    I have the nvidia quadro 600 graphic card. I use one monitor via DVI and i am trying days now to connect the TV also, through a displayport to HDMI adapter and a HDMI cable and system does't recognise the connection.

    Anyone can help me please?

    graphics card - Converting DisplayPort and/or HDMI to DVI-D?
  • Jeff Atwood

    Newer Radeon video cards come with four ports standard:

    • DVI (x2)
    • HDMI
    • DisplayPort

    enter image description here

    If I want to run three 24" monitors, all of which are DVI only, from this video card -- is it possible to convert either the HDMI or DisplayPort to DVI? If so, how? And which one is easier/cheaper to convert?

    I did a little research and it looks like there isn't a simple "dongle" method. I found this DisplayPort to DVI-D Dual Link Adapter but it's $120; almost cheaper to buy a new monitor that supports HDMI or DisplayPort inputs at that point!

    There's also a HDMI to DVI-D adapter at Monoprice but I'm not sure it will work, either.

    AnandTech seems to imply that you do need the DisplayPort-to-DVI:

    The only catch to this specific port layout is that the card still only has enough TMDS transmitters for two ports. So you can use 2x DVI or 1x DVI + HDMI, but not 2x DVI + HDMI. For 3 DVI-derived ports, you will need an active DisplayPort-to-DVI adapter.

    From what I heard, the cheap adapters don't work because you need something that generates an TDMS Signal. The cheap adapters expect the source to already support a TDMS Signal and more or less just convert mechanically.

    I have a post here. I ended up buying a $100 Dell Adapter which works, but fails whenever power savings comes into play (I basically have to unplug/replug to "reset" the adapter).

    In hindsight, I would have bought a Display Port Monitor or a second card, both options would have been cheaper and less problematic than the Adapter, but I already had 3 screens.

    Edit: After 2 Weeks, I really regret it. The adapter just "crashes" after some time (black screen, sometimes it turns on, off, on, off... My Monitor always stays on, so it's the adapter not generating a picture signal anymore). I'll try a USB-Charger next as they hopefully have more power, but I now really regret not getting a DP Monitor instead.

    If you can live with 1920x1200 resolution:
    HDMI to DVI Cables for $20+
    DisplayPort to DVI Cable for $30+
    If you want 2560x1600, you need an active adapter.

    Yeah, the way the Radeon hardware works, is that one display circuitry drives both the DVI2 and the HDMI port. So you can't have them both hooked up at the same time. Therefore to get 3 monitors, you have to do DVI+DVI+DisplayPort, or DVI+HDMI+DisplayPort. DVI+DVI+HDMI is unfortunately NOT an option.

    I believe the DisplayPort to VGA adaptors for ~$20 should work, if you can live with an analog signal on your 3rd monitor that's limited to 1920x1080 or 1920x1200 (most monitors are this size or smaller anyway still). The reviews on monoprice show it worked for 3 people with this card, but did not work for one person with this card.

    This is a more general answer regarding being able to use HDMI-to-DVI adapters and ignoring your specific problem (described on the Andantech page you linked to (paragraph starting with "Making 4 ports fit on a card...").

    With my graphics card (Geforce GTX 275) I got an HDMI-to-DVI adapter which looks like the "HDMI Male to DVI-D Female adapter" at monoprice.com and works fine.

    So unless there is a limitation like you have it an HDMI-to-DVI adapter should work, too.
