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 (<span class="myEmphasis">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.<br /> <br /> Unfortunately my Google searches this morning for this have had a pretty low signal to noise ratio. Mostly people having problems with nVidia drivers.<br /> <br /> Possibly relevant h/w info: </span><span class="myEmphasis">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.<br /> <br /> Thanks for any advice.<br /> <br /> Gilles<br /> </span>

<p>The short answer is... pretty much anything you can buy at this point will do what you want, except for some of the older cards.</p>
<p>I tend to stick to fanless cards, since the fans are always the first thing to die, however there aren't all that many of them out there, and they don't tend to support 4K but it varies widely.</p>
<p>The AMD/ATI cards don't need precompiled 3rd party drivers, but that doesn't mean they work better. I haven't had much trouble with the nVidia drivers... and if you don't need 3D performance, just use the Nouveau driver which works fine for 2D.</p>
<p>Regardless, a quick search on NewEgg reveals a handful of options that fit your bill:</p>

<p>I have not checked each chipset against the latest CentOS X.org drivers for compatibility, sorry. That's one reason I actually prefer the nVidia experience - they update faster than the AMD drivers. (Usually. Except when they don't. YMMV.)</p>
