Enabling a 4th monitor

I am currently having trouble with my multi-monitor setup. Before now I have been using 2 monitors and a HDTv, but with the recent black Friday I got another monitor. When I hook it in and go into my Control Panel>Adjust Screen Resolution it can detect the 4th monitor but when I try to Extend Desktop Display to the 4th monitor I get a popup saying that I am unable to save display settings. I have also tried tinkering with CCC but that didn't get me any further. Maybe I missed something in the Control Panel or in CCC.

As for my graphics card I am using: http://www.asus.com/Graphics_Cards/AMD_Series/HD7770DC1GD5/
I have my monitors hooked into the mini display ports and the DVI and the HDTV hooked into the HDMI.

  1. While the graphics card does have four ports, it will only support three displays at a time. If you want to support more than three monitors at a time, look to the Eyefinity-6 version graphic cards or install a secondary graphics card into your system.

  2. This graphic card has the eyefinity-6 capabilities.
  3. You must be using active display port adapters for this to.work. If it will at all. You could just use the CPU graphics for the 4th monitor if you have an Intel or APU

    No, your card is not Eyefinity6 capable. Eyefinity6 cards have 6 Mini-DisplayPort connections (see here). Your card will only support up to three monitors at a time in Eyefinity. If your motherboard has on-board graphics, you can, as Unksol suggests, try to use that for the fourth monitor.

  5. Ok so the information you've received doesn't seem quite right. You can have up to 6 monitors/screens with your card , 1 DVI, 1 HMDI, and 4 mini-dp (splitters required).

    You have 1 TV hooked up via HDMI
    You have 1 monitor hooked up via DVI
    You have 1 monitor hooked up via mini-dp

    Is your 3rd monitor hooked directly into the card via a mini-dp cable or mini-dp to dp? Do you have an adapter to change the mini-dp to something else like DVI? If so, is it an active adapter?

    Then repeat those questions for the fourth monitor.
  6. http://www.amd.com/us/products/desktop/graphics/7000/7770/pages/radeon-7770.aspx#2 for reference. Look at the Specifications tab and you will find the following.

    "AMD Eyefinity multi-display technology1

    Up to 6 displays supported
    Independent resolutions, refresh rates, color controls, and video overlays
    Display grouping
    Combine multiple displays to behave like a single large display
    Discrete Digital Multi-Point Audio (DDMA)"

    AMD Eyefinity technology works with games that support non-standard aspect ratios, which is required for panning across multiple displays. To enable more than two displays, additional panels with native DisplayPort™ connectors, and/or DisplayPort™ compliant active adapters to convert your monitor’s native input to your cards DisplayPort™ or Mini-DisplayPort™ connector(s), are required. Support for six simultaneous displays may require complementary products compatible with DisplayPort 1.2 Multi-Stream Transport. Maximum number of configured displays may vary - check with your component or system manufacturer for specific model capabilities and supported technologies. SLS (“Single Large Surface”) functionality requires an identical display resolution on all configured displays.

    Most current cards with Eyefinity capability have at least a maximum of 4 monitors if not 6.

  7. Huh! I stand corrected!

    My apologies.

    AND this is the core probem, as far as I know there arent any dp1.2 hubs or 1.2 multistream compatible monitors available yet... pls post a link if you know any.

    "Display connectivity options include one DVI port, one full size HDMI port and two mini-DisplayPorts. You may use all the outputs at the same time, thanks to AMD's superior display output architecture."
    but also remember
    "AMD has designed their HD 7000 Series cards to provide two TMDS clock signals. DVI, HDMI, passive DP Adapter consume one, while an active DP adapter needs no clock signal from the GPU."
    so either native dp monitors or active adapters for 4 monitors on your 7770 card
  9. Don't believe the 1.2 hubs/splitters are out yet, which certainly makes it more difficult. However the card certainly has the capabilities to drive the 4 screens with nothing more than an active mini-dp to xxxx adapter. Just need to know how it is currently set up.
