Installation and Software
Once you have the card installed you will need to attach your displays correctly.
Here you see our GPU test bed connected with all four of the DVI cables connected and ready to go.
One of the few negatives of a hardware-based model like the IDT solution provides is that you can’t change the orientation of the monitors in software and thus need to get the order of the cables correct. Unfortunately, there are no labels or anything on the dongles or even on the back of the card to indicate which should be the left and which should be the right display. Luckily, the worst case scenario is having to switch the DVI connections on each dongle one time.
For our testing we are using a set of four Dell 22-in monitors with a 1080p resolution. And yes, we just happen to have this setup around for testing this exact configuration. Notice the mess of wires that four power cables and four DVI cables creates – be prepared for some cable management here.
I should note that even though we are showing a 2×2 stacked configuration on our monitors you can of course run 4×1 and even 3×1 if you’d like. You could use only one or two displays, but if that is your ultimate goal there is no need for an MDT solution at all – any graphics card will run two monitors without trouble.
After just plugging things in, installing the NVIDIA driver (we used 290.53) and rebooting, we were met with this setup. You’ll notice that our bottom row is backwards – the span of the displays actually is reversed as you can tell from our window that is split across the outer edges of the monitors. A quick swap of those two DVI connections on the Galaxy MDT GeForce GT 520 dongle and we were set.
Galaxy does include one piece of software on the included DVD that we find to be quite useful – simply called Galaxy MDT. This application allows you to toggle between span modes and individual display modes depending on user preference. You can see in the image above that we have it set to individual mode where each monitor "acts" like a separate monitor in terms of maximizing windows. By hitting the standard Windows maximize button in Internet Explorer the window only expands out to a single monitor.
In the "span" mode hitting that same button actually pushes the IE window out to go across both of the monitors connected to the same IDT chip and same MDT dongle. Depending on your work load, spreadsheets versus browsers, different consumers are going to want different things here and an incredibly easy software swap makes moving between them painless.
Just to show you what your configuration options would look like, here is a screenshot of a 7680 x 1080 resolution when both IDT configurations are set to be next to each other in the Windows display properties.
And, if the stacked configuration of 3840 x 2160 is more interesting to you, here is a screenshot of that real estate.
Obviously having four monitors isn’t a necessity for everyone but after using more than a single screen for any length of time you quickly find the utility of keeping a variety around you.
