Can anyone confirm that the above 4-port card is supported at its full resolution and capabilities under CentOS 6 and/or 7? The card has four DisplayPort 1.2 connectors, each capable of driving a 4K monitor.
I haven’t tried that card specifically, but all nVIDIA cards I have tried work well with the proprietary driver. I am currently running a M2000 driving three 4K monitors. You have to use proprietary driver.
According to NVIDIA the card is supported by the latest NVIDIA
I believe support was added in the 346.xx series driver, so anything newer than that should support your card.
Hope that helps.
