For those that need their virtual workspace spread across several displays at once, Colorful has created a graphics adapter that will neither fail businessmen nor butcher their budget beyond recognition.
GeForce GT 640 Pro X4, it is a version of the GT 640 that does not have normal display outputs. Instead, it has two DMS59 ports.
One needn't worry about it being useless though. As it turns out, the unusual ports are there only so that, through use of special cables, they may power two DVI-I ports each.
DVI connectors are quite large, so four of them can't exactly fit very well on the rear panel of a video card, especially when that card is supposed to fit in the space above a single PCI Express slot.
Thus, the board ships with two cables that turn each DMS59 into a pair of DVI-I single-link ports, each with a digital resolution of up to 1920 x 1200 pixels (16:10 aspect ratio).
To lower interference, each DMS59 is equipped with electromagnetic energy shielding (EMI shielding).
As for the specifications, they are as follows: a 28nm GK107 GPU (graphics processing unit with 384 CUDA cores) with a clock speed of 900 MHz is backed by 2 GB of GDDr3 memory at 1,782 MHz.
Normally, the GT 640 would have only 1 GB of RAM, but the maximum resolution across four monitors needs a larger capacity if things are to run smoothly.
Finally, the TDP (thermal design power) is quite low, at 65W, which means that the thin, single-fan cooler is more than reasonably low on the upkeep.
All things considered, businessmen should have a strong incentive to acquire this product over a Matrox
video wall adapter. The only bits of information currently not known are the price and, by extension, the availability date. We suspect shipments will begin soon, but online retailers will have to show whether or not that assumption is true.
