How to connect 3 DVI Monitors to ASUS Radeon 7850 HD

[Draiget]

Hello,

I have three DVI and one VGA monitors:

• 
  ■ BenQ GW2250 (FullHD, DVI-D, VGA)
  ■ BenQ G2250 (FullHD, DVI-D, VGA)
  ■ BenQ GW2260 (FullHD, DVI-D, VGA)
  ■ Samsung SyncMaster943m (1024x1280, VGA)

Two video cards:

■ Sapphire Radeon 6670 HD (Outputs)
■ ASUS Radeon 7850 HD (Outputs)

How i can connect 3 HD monitors to Radeon 7850 (for AMD Eyefinity desktop)? I try DP-DVI and HDMI-DVI cables in multiple combinations, but works only two monitors.

doesn't it work to connect 2 on 8750 (for example the 2 benq gw) and 2 (third benq on dvi and samsung on dsub) on 6670?

Yes, i can connect all monitors to both cards, but i don't have Crossfire bridge, and can't use AMD Eyefinity (One desktop for 3 monitors).

check in bios for a "surround view" option or something like that it should work even without the bridge. if not, you need an active adapter for the last monitor on the monitor on 7850.

active adapter for the last monitor

DVI (Monitor) --- DVI (Card)
DVI (Monitor) --- DVI (Card)

And active adapter DP to DVI, or active adapter HDMI to DVI?

doesn't matter. whichever you find cheaper. probably hdmi to dvi.

thanks, and one more question, this is active adapter? (DH1803G)

 

[laviniuc]

nope, that looks like a passive one

this is active adapter - A-DPM-DVIF ? Dual-link adapters have UDB power cable, but how to find single-link converter, they do not have power wires?

i'm not sure about this one either, perhaps you should go to your closest computer parts shop and ask for an active adapter...

edit: this should work ok:
