check out this unreleased custom design GeForce GTX 580 graphics card by Galaxy. The card has redone display logic that gives it a total resolution of 5760 x 1080 (the MDT technology). 3x 1920 x 1080 displays can be connected to it without needing another card. Its display outputs include three mini-HDMI and a full-size DisplayPort. Display management is backed by Galaxy's in-house EZY display setting software.
The card uses a huge heatsink to which heat is fed by a number of heat pipes, and ventilated by three 80 mm fans.
