Eyefinity w/ Three monitors.

[Commandershell]

So I just recently setup three screens for eye finity.  x1 DVI. x1 hdmi, x1 VGA.  The problem is the hdmi monitor is not being detected.  Any reason for why this is happening?  By the way, my graphics card is an AMD Radeon 7770 Ghz edition 2gb.  Any response is greatly appreciated.

- Cheers

Can you swap the HDMI monitor to plug in the DVI cable and vice versa for the DVI montior?

[AfroStorm]

Why are you using VGA? That is just a bad idea.

have you tried using different connectors for each monitors

Also the exact model of the graphics card would be apreciated?

AMD Radeon 7770 Ghz edition 2gb

Sorry but Eyefinity with that is just a bad idea.

Also you will need three exact same monitors for this to work. Eyefinity is all of them acting as one. not just three monitors running windows.

You HAVE to use DisplayPort as the third connection. Only 2 max from a combination of hdmi/dvi/(vga)

this

 

AMD drivers only allow two monitors at max with passive connections. Third monitor must be displayport or displayport >DVI/HDMI active converter (~30$ DVI active)  or through a displayport hub.

Oh okay, the display port part makes sense because VGA sucks.  Thanks everyone.

Just don't use VGA? Solves at least one of the problems

[BrightCandle]

VGA is using one of the clock sources and your card only has 2 clock sources. Displayport doesn't use a clock source on the card so one of your three monitors must always be based on displayport. Its annoying limitation but once you use DP it should work.

 

If you don't have display port on the monitor itself you will need an active adapter, as it needs to generate that clock source.

I figured it out.  Thanks for the help.
