I believe it's just leftover from the configuration I had in my older case, the case wasnt that good and I believe it didnt fit properly if I remember correctly. I havent had an issue with it, and I've had the GPU in that slot for almost a year now. Also, I tried different cables, and using the first PCIe slot. Still no output. Curiously, using a display port, the monitor LED is white, which indicates its receiving an input, but the screen is still black. The monitor itself is almost brand new, and the display works (When I turn the monitor on, the MSI logo appears like normal, and I've noticed a brief change of brightness sometimes when I've been boot testing)
