From my understanding and research of the subject this should not be the case with the setup that I have.
I have tried a few obvious things like having same resolutions @ 1680*1050 (AW defaults to 1900*1200, LG 1680*1050), while there a few simliar problems out there I can't seem to put find the answer, can anyone tell me what I'm overlooking or what the cause of my problem is?
Oh, and FYI. Initially using the DP -> DVI adapater for the new AW 120hz monitor resulted in not being able to access the 120hz 'feature'. Thus I'm now linking the AW monitor with 'true DVI' (no DP adapter). Therefore one of the LG's is true DVI while the other is DP -> DVI.
An active adapter?
I cant explain it very good tbh But as i have understood the normal 5k series cards can give an individual signal to 2 monitors, and when using an active adapter it will be able to handle 3 monitors instead of 2.
Can you link to the adapter ur using? that way i can say if its active or passive
EDIT: The difference between active and passive is simple.
Passive adapters are merely a cable to go from displayport to DVI/HDMI/VGA/w.e. The video card detects the monitor as such, and outputs the required signal (DVI/HDMI/VGA). This does require one of the two aformentioned clocks, hence why they do not work with eyefinity cards.
Active adapters, on the other hand recieve a displayport signal from the video card, and convert it to DVI/HDMI/VGA. They will always have some sort of onboard DAC or video converter chip which they use to convert the dp signal. Lately, most everyone has been referring the DAC ones (which are the converters that go DP->VGA) as 'passive.' This is not the case.
Thats the kinda adapter ur looking for. Thats a DL-DVI adapter, theres SL-DVI adapter out there too thats a little cheaper but can only handle resolutions up to 1920x1200, but thats no problem in ur case.
Unfortunately i didnt find any SL-DVI adapters on that site. When buying an adapter u should look if it says Active, if it dont its a passive one.
If theres any other website u are able to buy from u can link that and i will check for a SL adapter for u
As a sidenote to anyone that might stumble upon this (although feel free to correct me if I'm wrong); if you're using Display Port to connect to a 120Hz monitor then you'll most likely only be able hit a maximum of 60Hz. This is of course a problem with the HD 5970 as while you have 2 DVI's you're stuck having to use a Display Port. Hence a single HD 5970 can only output 120Hz to 2 monitors and the other on the DP will be stuck @ 60Hz.
