Need to make a 4 monitor 4k display. Radeon Eyefinity?

Hello, if anyone could help me fill in some gaps in my understanding, it'd be much appreciated.

So I am trying to make a 4k display out of 4 separate monitors. I've concluded Radeon Eyefinity is probably the cheapest and best way to do this, as Nvidia Mosaic is only available on Quadro's which cost way more for comparable power.

First, to get 4 monitors plugged in, do I need to get something like this?

280x with 4 display port outs on it.

OR

Is there someway to get 4 monitors plugged in via the connectivity on a standard 280x

Second, do the displays have to have native display port for whatever reason? Or could I use HDMI plugged into an HDMI to display port convertor, plugged in the 280x?


Third, this is stupid question, I just want to make sure, I haven't touched any radeon product in years. But 4 monitors plugged into a 280x can be configured to be a 4k display through eyefinity, right? 2 on top, 2 on bottom.

BUT does the eyefinity software also let you rotate displays? So lets say I want the two bottom monitors resting flat on the table, then I want the top two monitors hanging upside down from the ceiling. Can that be done? If that can't be done with eyefinity, can quadro's by chance chance do this?

Since you are only trying to emulate 4K using 4x 1080p monitors you don't need any fancy connectors. The Radeon card itself has to support 4 monitors (280x support 6).

On the 280x you can have 2 monitors connected in total to any combination of DVI/VGA/HDMI, the other 2 will have to be plugged into DisplayPort. On a 290/290x you can have 3 monitors connected to DVI/VGA/HDMI.

If your monitors are not DisplayPort you can get cheap ($30) DP-to-single-link-DVI adapters. You don't need the expensive dual-link ones as you are not going over 1080p.

You can configure the monitors the way you want in Eyefinity, worst-case scenario is to use VESA mounts to rotate them physically.

How do you hook up multiple monitors to display port?

Also, this screen is not going to be made with standard monitors, it's actually going to be made with vivitek HD ultra short throw projectors. Which cast the image up and out from the unit, almost from a 45 degree angle. So to put the projectors on the ceiling and have them project down, and I have to be able to physically invert them. Although I just realized that maybe the projector itself can do this, I'm going to send off an email to them and ask. But still would be nice to know if eyefinity can do this.

Keep in mind that you will need an active display port connector instead of a passive. Using a passive connector means you can only hook up a maximum of 2 monitors. An active display port connector allows more then 3 monitors.

Absolutely correct, I forgot to put in that detail - thanks for correcting me.

If you use a MST 1.2 hub you don't need active adapters as the hub does all the work, but that's assuming you get a hub. *ALL* 290/290x can output to 4x 1080p monitors without the need of a MST hub.
