    Good choice going for 3 horz monitors... Can't you make the background span all 3?

    they only gave me one crossfire cable - from pics on net looks like you need 2 (to join the cards)

    the 2 - 1gb cards arnt powerful enough... going back to first 2gb card - but 2 of them

    so - this should be working when i get back from comp store...

     

    and when it is - ALL these going portrait.. so games wont stretch so much

     Still no eyefinity...

    If you use 2 cards - with crossfire - that means one cards outputs no longer work - only the top card.
    Since all the 305t's are DVI with no display port - I can run one from card - and one from Displayport using an Active DP - to DVI contvertor (130 dollars)

    so that leaves one monitor out.  I saw dell and cirago have DP - to DVI hubs with 3 DVI ... great - till you check the maximum resolution - which isnt 2560 x 1600

    So thats out...   so far Ive only found ONE way to do this - but its a 500 hundered dollar box!

    My last option is this thing - for 30 bucks

    http://www.cty.ca/productdetails.asp?pid=3882

    but who knows if it will downgrade the resolution like the other hubs

     

    the moral of the story - dont f__with displayport unless all your monitors have it too Tongue Out

    Well, I think we all know I couldn't sit idly by without submitting my two cents.  I just got Eyefinity 6 set up the other day.

    Used one ATI Radeon HD 6870 Eyefinity 6 Edition for the six-way. Has six mini-DP ports, comes with mini-DP to big-DP adapters. Had to buy six big-DP to DVI adapters. The other two are on the onboard. Removed my three Radeon HD4670s. My one video card is lonely Sad

    all using displayport most likely...?

    @jamie: Somewhere along the way, yes. The card has six mini-DP ports. From there they go into six mini-DP to big-DP adapters (included) and six big-DP to DVI adapters (not included). From there into the monitors' DVI ports. I believe it supports 2x2 and 1xN setups.

    i have 2 - sapphire 6950's - 2 gb each

     

    Generic Forum Image

    1 - dvi - 1 - vga - 1 - dp - 1 hdmi

    would need fianl res to be  4800 x 2560

    Didnt you need Active adapters? 100$ ea?

    do you think this thing would work?

    http://www.cty.ca/productdetails.asp?pid=3882

     

    also - do you get windows messages that say "windows cannot determine the resolution of displayport...etc.."  Dont show this message again __

    ?

    PPS - whats the highest res you can go?

     I bought six of these at $25 each, which do up to 1920x1200.

    I have no experience in video signal splitting, multiplexing, etc. Makes sense that it could do DVI-D to two single DVIs, if your adapter has the right output signal and port, as I understand it. I've never really bothered with the dual link thing.

    No, I don't. I do have some artifacting when Aero Glass is enabled, but that seems to be at the desktop level and not the output level. That is, an artifacted window will stay artifacted as I move it around among the screens. Even to the screens that are on the onboard. So I just turned DWM off.

    My screens support up to 1920x1080, so in six-way Eyefinity mode I can get 5760x2160 or (I would expect) 11520x1080.The card's specs report support for up to 2560x1600, which is obviously per port. So I'd guess it could probably handle 7680x3200 or 15360x1600. Finding games that support it, however, is another story. I like the 1080p screens because I can watch native 2160p video, when I can find any Smiley   With the two onboards on the right, I run total 7680x2160.

    thanks...  sigh

    i just spent 2 hours - trying to get back to where i was (running all 3 - at correct res)

    solution?  remove all ati - completely.

    reboot a few times - windows set them up properly.

     

    You know... im really not an idiot.. ha ... but this has been ridiculous.  Ive been getting blue screens - like 30 times - when ever i go near crossfire.  when eyefinity works - sometimes - you get the weird lines...  windows reports it cant determine video res - ignore .... windows "automatically" kicks me into windows basic - becasue i dont have enough video (4gb) - or  trying portait "flipped"="unable to change ati settings"

    the whole things a joke.

    after giving up - i thought - hey - even though i can only use the outputs on one card - and vga (that looks like dvi) only goes to 1536 x 2048 - hey - that port supports it (so it says) - so i wont care about windows apps at 2560 - if i play a game - ill just move a cable or 2 - and run lower res! genius!

     

    thats what lead to 2 hours of trying every cable combination - crossfire - with + without - anything....

    it is a JOKE! and not a funny one.

     

    In those DAMN old days i always talk about - if you put 2 of the same cards in a machine - doesnt something have to change on one?  could this all be about interupts and irqs and sh_t i havent thought about in 8 yrs?

    Did the guy who installed it (shop) just throw them in - he told me he never even booted it....

    or - is that how stuff works now - and im just - f**ed

     

    Anyway - i did get back to 3 - running correct res - no crossfire - no ati - just windows

     

    thanks ms

     

    PS - i am thankful for new machine - and the 3 - 30" mons all running right res - in portrait. my first idea (see other thread) actually worked.  To bad friggin Geforce didnt come up with eyefinity - i NEW ati was bad news

    pps - im actually extatic... solid state and win64 / ram was the big deal - LOVE it

    ..i just went so much out of my way - to do eyefinity - for quakelive (of all things) and it didnt work.

    oh well.  im fortunate to have what i have ... its so fast... Wink

     

    *and dont negate 3 portrait mon's  =  rectangle
     (3 horizontal hurt my NECK! and was like looking at a 2 by 4  Smiley

    ...pretending...but ...FUN Smiley

     

    edit: thanks - UltraMon..

     

    edit 2: now if i could just figure out how to contain games that want to launch in full screen - to a window - that i could drag to all corners of the 3 monitors - i wouldnt need eyefinity.

     

    ps - what is it with me and full screen! lol

    I didn't know about Quakelive. It's so retro looking Wink

    Glad to know ATI made an update that actually works.
