Being an AMD exclusive partner we believe that AMD helped Club 3D make this happen. The fact that Club 3D has a unique product in the form of the multi-stream transport Display port hub, made it easier to make its presence in the US.
Club 3D SenseVision Multi Stream Transport (MST) 1-3 DP Hub Model CSV-5300U splits a single display port to three monitors, each supporting a maximum resolution of 2560X1600@60Hz on display port 1.2 MST standard or Full HD on DP 1.1 monitors. This hub is planned for Radeon cards and it’s ready for AMD Eyefinity technology
Of course, Club 3D also has Radeon R9 260X, 270X and Radeon R8 280X cards at launch and you can find them all listed here.
