Hi all - I have a question about using multiple monitors. I presently run a dual monitor setup, with each monitor connected to the outputs of my GPU. I was running a crossfired GPU setup; however, sadly I lost one of them - no idea why, but one of them fried. At any rate, I recently came across another monitor that I had stored away, and what I'm wondering is this: Since I only have two monitor outputs to work with, will I still be able to use DisplayFusion to give me three separate windows - one on each monitor - or will I be forced to have two of them be duplicates of one another? I suspect that, since I would have to use a splitter to accomplish the addition of a third monitor, that two of them will have to be clones of each other.

 

On the other hand, if there's a workaround to be had, I know that I can find it here... :D

 

This is of no urgency - in all honesty, I only want to do it becaue of the coolness factor of having three monitors...

 

Edit: I have not yet changed my system specs to reflect the loss of one GPU. All else in the specs below remains trhe same.

It seems you have more then 2 outputs 1. Dvi single link, 1 Dvi dual link, 1 HDMI, 2x mini display port. From my exp with my HD7770 You can use the 2 dvi and one of the display ports. You may need an Active adapter

Well, DUH! I apologize for being dense. The monitor has only two inputs - DVI & VGA, so I jumped to the conclusion that I would have to use one of those output ports. Further searching, however, turns up this adaptor. I'm assuming this would work, and if not, well, I'm not out a whole pile of money.

 

Thanks for your response. :thumbup2:

You need to use at least One monitor connected to the display port and use an Active adapter

Yeah - I did a little more research and found that out. It seems kind of odd to me to configure the GPU that way, but I'm not an electronics engineer, so I suppose there must have been a good reason for it. The active adaptor isn't all thaat expensive, either, so I'll go ahead and order one.

 

Thanks for yor help.

That site is what helped explain it to me the first time I ran into that problem.

Okay, not to beat a dead horse, but before I go through the potential hassle of buying the wrong adapter, I'd like a bit of clarification, if possible. I can't find anything as specific as I'd like doing web searches, so here goes:

 

The ports on my GPU are shown in the picture below. I know that I need to purchase an active adapter, but I need to know if I'm constrained to using a Mini DP to HDMI, or if I can use a Mini DP DVI - or if it matters. My monitors have inputs as follows:

 

Monitor 1 (Main Monitor): HDMI, VGA

Monitor 2: DVI, VGA

Monitor 3: DVI, VGA

 

The specs for both monitors 2 & 3 do not specify whether the DVI ports are DVI-D or DVI-I, so I suspect they are both the latter.

 

So, I suppose that what I'm asking is this: Which of the following configurations is most likely to work?

 

1.) Monitor 1 input: Mini DP to HDMI, Monitor 2 input:DVI, Monitor 3 input: VGA

2.) Monitor 1 input: VGA; Monitor 2 input: Mini DP to DVI; Monitor 3 input: DVI

 

Of note: I tried once to connect my main monitor using HDMI - it worked fine, but would not allow the second monitor to function using either a DVI or VGA connection.

 

Any help with this (for me) extremely confusing situation would be appreciated.

Sorry - I forgot to add the image, and it seems that I can't attach a file now for some reason. The image is located here.

I just want to post an update here: I bought a mini-dp to DVI active adapter. I now have one monitor running with that connection, one that uses a DVI out on the GPU, and one that uses the second DVI out, with a VGA adapter. Apparently, you cannot use the HDMI if one of the mini-dp ports is being used. It's not that big a deal, though - I have three monitors, each acting independently of one another.

Thanks for posting your update, I apologise I missed your last question. For reference most DVI ports on video cards are DVI-I (single or dual link) this makes them compatible with DVI to VGA adapters. DVI-I includes the 4 analog pins surrounding the blade or slot pin. Monitors, depending on the resolution will use DVI-I single link (1900x1200@60Hz) or dual link (2560x1600@60Hz) connectors.

I've been trying to research on my issue about my DVI port. MY card has a DVI port (24+1) and a VGA port. The VGA port is working but not the DVI port. I have purchased numerous adapters and a VGA to DVI cable but still doesn't work. Any suggestions?

You should start your own thread and specify what video card you have.
