Post subject:	Setting up eyefinity with 3 monitors - experiences and difficulties (mostly SOLVED)
Its quite depressing how much work such a damn triple monitor setup makes.. we fly to the moon... but with only two monitors as it seems... I have trouble as well to get the three monitors runnin. But i think my prob might be a bit diffrent from most experiences. Setup: 6970 PCS+ 3 Benq g2420HD (With 1 D-Sub(vga) , 1 hdmi and 1 dvi plug 1. monitor - HDMI (in the monitor) to DVI (at the card) 2. monitr - DVI to DVI 3. monitor - D-SUB (vga) to DVI to miniDP via Active SINGLE link dvito miniDP adapter http://www.amazon.de/XFX-Mini-DisplayPort-DVI-D-Adapter-Single-Link/dp/B004CV9YMI/ref=sr_1_1?ie=UTF8&qid=1315230480&sr=8-1 Result: 2 monitors working one isnt.. simply... I also tried to run the 3rd monitor with DVI to active single link adapter-miniDP same issue... The funny thing is i dont even get a single montor running on the miniDP no matter if i use the DVI or vga cable... Should this work? is my craphics card broken maybe or another issue? next thing is, if i plug all in the config i think was the most clever one (like above just with DVI at the adapterminiDP) Windows shows me 3 monitors, but the third isnt shown as benq but as "VGA display" . I cant extend on it if i plug only 2 AND i can go with my moue on it BUT without seeing anything! the monitor says no signal.. if i plug all three i cant extend on the third "VGA display" one, it says it cant save the settings... Ive read posts and things fo hours now.. im clueless... can anyone pleeasE! help?

Post subject:	ok, I now borrowed an active
ok, I now borrowed an active miniDP DUAL link adapter with usb power supply (that 100€ thingy) form my office and it was plug n play... I also bought another active single link adapter (30€) to VGA - jsut to test that one too... Ill post the result here since noone else seems to know more about that topic as soon as its delivered. Still i got another "bug" even with the expensve active adapter. It went to no signal after tabbin out and in a few times of bf2bc and back. de and re plugging (hotplugging) helped but i gotta check why this is, cause i dont wanna climb behind my pc everytime... i gues sit has sth to do with the refresh rates.. dunno.. cu O

Post subject:	As promised ill date this up
As promised ill date this up again, Since noone was "answering" yet i think either this was too boring or nobody had a clue about it. So i changed the topic a bit, so IF there are other people out there with problems (and im SO sure there are) they might find this useful. I now got the new adapter (active SINGLE link 30€) http://www.amazon.de/HP-DisplayPort-to-VGA-Adapter/dp/B0025ZUF8K/ref=sr_1_1?ie=UTF8&qid=1315588284&sr=8-1 first of all, this one worked at my machine without difficulties. I can set up all three monitors with it without trouble at all and in full hd each (1920*1080) I was a bit frightened that the vga connetion might look crappy but, wether im half blind or there are no noticeable (maybe measurable) diffrences. And I also changed my cables to (direction is always form monitor to card) : 1.Monitor VGA to VGA active Adapter (mentioned above) to miniDP adapter (delivered with graphixcard) 2. Monitor HDMI to HDMI 3. Monitor HDMI to DVI (no adapter - cable integradet) I had some issues with an DVI to DVi on the third monitor... heck knows why.. cable is ok i know that but well.. dunno... this cable worked fine. NOTICE : it MIGHT do a diffrence which DVI port at ur GraCard you use , since for example my 6970 has a Dual link DVI and a Single link DVI Output. I experienced that some combinations of using the slots might result in black screens. I wont go any further in that cause its a lot possibilies , just be sure to try some combinations before u throw the pc out of the window in nerdrage. I had some other Issues with 2nd monitor since the picture wasnt really sharp and a BIT blurry. Also it had black bars at all corners. to solve this u got to unable "over/underscan" of your monitor (in monitor menu) and put the overscan option in the CCC to 0% ! (its at the scaling options - ull find it) by doing so u ll get a REAL sharp picture - since HDMI signals are digital , dont believe this has sth to do with ur cable quality since, digital technology is mostly do or die , meaning wether u get 100% quality or no picture. Ill report if my "bug" mentioned above (DP monitor going black after tabbing in and out a few times) is gone too with the new setup. I still think it has sth to do with the translation of the whatever to DP translation while changing refreshrates. I also read that this MIGHT have sth to do with too small PC power supply. Im runnin 550 W so this MIGHT be true - but not proved yet. Ill date this up in a few days or so as soon as i know more. Im pretty happy i got this running now without buying expensive active DUAL link adapters (with usb power ) and I hope this thread will help people, since due to my experience there arent many helpful threads in the web and most people dont know how to distance - troubleshoot too.
