Was digging around the office and found one of these:

I've noticed a lot of single head ATI cards supporting dual monitors via a DVI splitter as seen here:

On this particular V3600, there are two DVI dual link outputs. Would it be possible to hook up two DVI splitters and run four monitors?

Each of the two dual-link outputs can provide a maximum resolution of 2560 x 1600, or about 4 megapixels. Unfortunately, I believe this is limited to a single (but high resolution) display, per output. Page 2 of this PDF describes that two V3600 cards are required to support four 3D-accelerated monitors.

DVI splitters almost always mirror the output to two displays. An exception to this is that some video cards (particularly on Dell PCs) come with a Low Force Helix connector and a special "splitter" cable, which looks like this:

For clarifications sake, some Dell PCs come with a standard (not a non-standard) connector which allows two monitors to be connected to a single output port. This is called the Low Force Helix connector which uses a DMS-59 connector on the cable which connects to it. This is not Dell specific, this is a standard used by other companies and this non proprietary / open standard that anyone can implement. See – jetole Jan 12 '11 at 21:49
@jetole Well spotted! – sblair Jan 12 '11 at 23:00
