Hi. Does anyone on the list have experience and recommendations on how to support a 4k monitor under Linux? We want to use a single Dell 27" 4k monitor (P2715Q) with a CentOS 7 system. What would be a good choice for a PCIe x16 video card, preferably with DisplayPort output, that can support 4k@60 Hz and has good driver support under X.org - hopefully without having to resort to 3rd party pre-compiled, version-specific binary kernel modules? If we can keep the price for the card below $200-$300 that would be great.

Unfortunately my Google searches this morning for this have had a pretty low signal to noise ratio. Mostly people having problems with nVidia drivers.

Possibly relevant h/w info: ASUS M5A78L-Mlx+ motherboard and AMD FX-6350 CPU. Power supply has a spare 6-pin (3x2) PCI-E power connector for cards that require a dedicated power connection.

Thanks for any advice.

Gilles
