What cables and/or adapters do I need to connect 3 Dell U2412M monitors to my PC with a AMD Radeon HD 6670 video card
I do not know what specific cables and/or adapters I need to order in order to connect my PC with a AMD Radeon HD 6670 video card to 3 Dell U2412M monitors.
The AMD Radeon HD 6670 video card has a
- DisplayPort 1.2 port
- HDMI 1.4a port
- DVI-D with HDCPport
The card supports Eye-infinity and up to 4 monitors.
I think the monitors can all run off of the DP port on the card but they may need active adapters but I'm not sure.
What specific cables and adapters should I buy?
Thank you,
Bob

Hi Bob
I have been going thru the same thing only a little different equipment. I have a HD 5670 1GB GDDR5 on a DELL XPS 8300.
When I purchased it ...my main reason was to have multiple monitors (3) . I was told that it would operate multiple...it will if one of your monitors has a display port, and then you need a dongle but thats another story.
Dell recommends a display port which you have on your HD 6670 (good card I understand for the price) so you should have no problem connecting 3monitors
Go here and it should walk you thru

PS I was told I could do a splitter DVI-D but there is a change you may need to make within the AMD sofware not sure if you need to do this with the display port.
All I could add is, that a monitor with a display port will have better results versus one without and therefore utizing a dongle (Display port to ( VGA or DVID) monitor inputs)
Good Luck

I forgot, all your Dell Ultra sharp monitors have display port inputs therefore all you need is a "DisplayPort 1.2 MST HUB.
This feature is called Multi-Stream Transport, or MST, and it allows a single cable from the graphics card to carry the signal for multiple monitors. Taking advantage of this feature requires one of two things:
■A DisplayPort 1.2 MST-capable hub, which connects to the graphics card’s DisplayPort output on one end, and provides multiple monitor connections on the other.
■Or DisplayPort 1.2 MST-capable monitors, which allow a user to daisy chain monitors together, with the final monitor connecting to the graphics card.
Thats it
Cheers

PS I would have thought that Dell.com would have tried to sell these to you if you had purchsed the monitors thru them?

Hi Ray,
Thank you for the excellent information. It is really made things much clearer but I am still a bit confused.
What I think you are telling me to do is: string the monitors together in a "daisy chain"?
Each U2412M monitor has a DP, DVI-D, and a HDMI port so if I am hearing you correctly then I think what you advising is the following:
If the U2412M is a DisplayPort 1.2 MST-capable monitor (I am not sure if it is) then what I need to to do is:
1. Buy a DP 1.2 cable?
2. Plug one end of the DP 1.2 cable into the DP port of the video card in my PC and plug the other end of it into Monitor 1 then
3. Plug one end of a DVI-D cable into the DVI-D port of Monitor 1 and the other end into the DVI-D port of Monitor 2 then
4. Plug one end of a HDMI cable into the HDMI port of Monitor 2 and the other end into Monitor 3?
PC-Video card<---DP cable---->Monitor 1<--------DVI-D cable------->Monitor2<------HDMI cable------>Monitor3
Or is there someway to string them all together with a DP 1.2 cable with DVI-D to DP1.2 adapters or something like that?
I am still confused as to what cables I need to purchase but much less confused than I was before you pointed me in the right direction.
Gratefully yours, Bob
