Hi, i recently bought my new graphics card "before i was using a AMD 6950".

My OS is windows 7 proffesional N 64 Bit.

My Machine is updated and is using the latest Nivida Driver.

The problem is this, I connect my 3 screens with hdmi - mini hdmi cables to the 3 mini hdmi ports but only 2 screens turn on.

The card is detecting the third screen as in the windows and nivida panel i can change settings for it but the screen just says "Check signal cable" and in the nivida pannel it says "This display does not support HDCP" now considering this screens are all the same and well looked after i dont know what to do.

The Card is working fine "All ports are working".
The Screen works *Though when i take the same screen and switch it for a pre-working screens cable/power cable it doesnt work -_^"
and all the cables work.

Any ideas where i am going wrong ?

I think the card is only able to send 2 non display port signalsor atleast the reference card did.

If thats still the case all i will say is the marketing did its job of making people buy when it didn't meet there actual needs.

Nope, the 680 reference can output to 3 non DP monitors without any additional adaptors. The 4th screen must be running off of a DP adaptor though.

I run three LG-IPS321P monitors which don't natively support DP. I have them connected via DVI,DVI and HDMI to DVI. I ran exactly the same setup on the reference 680 I had before the custom cooled 670's.

IanN1990 - do you experience the same issue on the same monitor on any of the ports (card), or does it only affect the monitor connected to the same port each time?

Essentially try cycling your monitors between ports to narrow down whether the issue is at the card end or the monitor end.

or an issue with a cable.
