Here in this article, we will make an attempt to show you why you don't need a rather expensive more than a hundred dollar active dongle to truly use Eyefinity. While you'll need an active adapater to get beyond two panels (there is no way around this), it will not be required for you to buy a costly one so you can get there.
There are a couple of forms of dongles for Eyefinity: there's the passive adapater and the active eyefinity dongle. As with every other style of dongle, these adapters change one kind of signal into another. When all's said and done, the signals between DisplayPort and VGA/DVI connections are completely seperate, and simply aren't compatible. Due to this, you're gonna need one of these adapters.
The most common system that people with multiple monitor setups have is either 2 VGA or two DVI monitors, together running off an individual video card. This you can still still do with Eyefinity. The need is that at least one of those monitors needs to be working from the DisplayPort, along with an active one at that. A passive DisplayPort will not work for this initial DisplayPort panel. Think of it like your anchor panel.
For this anchor monitor, you can apply this 2 distinct ways. You could possibly either purchase a DisplayPort display, which can be still costly at the moment, or feel free to use an active Displayport dongle to translate that signal into VGA or DVI. Here is where the trick comes in. Most users default to DVI at this point, and the active DVI dongles are all overa hundred bucks. Therefore, what do we do in this instance? Taking into account that the vast majority of monitors nowdays are equipped with both Vga and dvi connectors, we buy an active DisplayPort to VGA eyefinity dongle, which cost nearly $30 at the moment.
Consequently, the uncertainty here is how is the video quality? In checks that we have made with multiple panels, if you try very intensely, you are able to catch a glimpse of a little bit of of discrepancy in some instances. Personally, I take advantage of a group of Acer displays that every one come with Dvi and vga connectors (and in addition HDMI), and I are not able to personally discover the differentiation between my monitor using the VGA port, and those using the DVI connection. This can be a economical alternative for those desperate to break into Eyefinity, and could well hold you over until DisplayPort monitors come down in price where you can obtain 3 or more matching displays.
