Reddit reviews Accell DP to VGA Adapter - DisplayPort to VGA (HD-15) Active Adapter - AMD Eyefinity Certified, 1920x1200 (Wuxga) @60Hz, Black

Venturing a guess here, I'd say your DP->VGA cable is passive. Swap it out for a (preferable) active DP->DVI cable or active DP->VGA, and you'll be able to run four independent displays using each of your connections.

Single/dual link isn't the problem. The problem is that one of the ports is DVI-D and thus doesn't send an analog signal which is why there's no picture since you're using a DVI to VGA adapter.

Can you connect the blank monitor to the card with a DVI cable? Otherwise you'll have to buy an active DisplayPort to VGA adapter (something like this).

What's wrong with the current setup?

All you need to hookup the third monitor to your graphics card (provided you properly linked your current card) is an Active Displayport to VGA adapter. I.e.

Ok, then a cheap adapter like this will work.

You likely need an ACTIVE adapter. Passive ones do not transmit the "connection is live" signal, so often times a computer won't even know the VGA monitor is connected. That isn't an issue when it's a 2nd or 3rd monitor (for the most part), but is a problem when it's the only monitor.

Something like this would likely work for you:

I have a triple monitor set up as cheaply as it can be done.
For the graphics card it must have eyefinity (im 90% about this, there may be exceptions but I don't know them). I don't think it works with nvidia quite yet so go ati.
I have a xfx 5830 that you can get for $130. My monitors out are an hdmi to one monitor, dvi to the second monitor, and to the oldest monitor I have an active display port to vga.

This last step is important and I will explain why it has to be active and to vga to stay cheap;

The reason it has to be active is because you already have 2 digital signals in the form of HDMI and DVI, so it has to convert it.

The reason it has to be VGA is because it uses less power and is easier to do so it doesn't need to be powered and MOST importantly, this adapter costs $25 for active displayport->vga compared to ~$100 for active to DVI.

My monitors are not all at the same resolution so I can't do the thing where it recognizes it as 1 huge screen. It is 3 seperate screens that I can control the positions of in ATI catalyst control center (the software side of the drivers... or something that comes with the GPU).

I am not sure about using both the DVI's and then the adapter that I link/ed but I don't see why not as the GPU sees the 3 ports as pick any two. Doesn't really matter as im sure at least 1 of the 1080 monitors has an hdmi cord.


Any other questions feel free to ask, and here is the link to the adapter that you need its not porn its just the link with a false name

side note; since doing my last batch of research, it seems there may be a chance of an active displayport to dvi... due to this product. May be irrelevant as i assume that the old monitor doesn't have dvi, but for anybody else.

it says "Connect a Single-Mode DisplayPort Enabled Computer to a DVI-D Monitor, TV or Projector" so it kinda sounds like it won't work with multiple monitors by the single mode statement... but not sure

Don't mean to be rude or anything but this would make the 295x2 work perfectly with your CRT monitor

I've had good luck with AMD cards. This setup has a fairly ancient 5770 with a pair of dvi and minidisplay ports. I then have to inline an active adapter as my thrid display doesn't have a displayport.

Thank you for the response, it does make sense. The only problem is dropping the money for another 5870 isn't practical for me. I was looking around and found this Display Port with VGA Active Adapter. Wouldn't that resolve the problem??

this is not true... I'm using a display port to vga adapter to type this right now on Eyefinity...

Specifically this one

Non-mobile: this would make the 295x2 work perfectly with your CRT monitor

^That's ^why ^I'm ^here, ^I ^don't ^judge ^you. ^PM ^/u/xl0 ^if ^I'm ^causing ^any ^trouble. ^WUT?

so something like this will work?

You can also use a DP > VGA adapter like this. I'm sure there are less expensive ones out there too.

I was worried about that. In my experience, if the onboard video is being used it won't allow you to use the pci card, that's why dell covers them. But sometimes it works. its a motherboard thing. :(

Best bet :/ other than purchasing a new video card.

I agree you shouldn't assume a passive conversion. We only get active adaptors to make sure we don't have to worry about it.

Active DP->VGA adaptors are about the same cost, compared to the apple adaptors anyway:

What's the brand and model # of your graphics card?

• If you're trying to plug in two VGA monitors, you'll likely need this adapter for the second one.

Not sure if there is a passive one, but Iknow this one will work. I have it and it works great and allowed me to use 3 monitors with one 5770.

I believe I need a displayport with a VGA active adapter. http://www.amazon.com/Accell-UltraAV-B101B-003B-Display-Adapter/dp/B003HC85D2/ref=sr_1_1?s=electronics&ie=UTF8&qid=1318283747&sr=1-1

Anyone know if this is correct?
