<div dir="ltr">Forgive my ignorance, but don't all current cards support 4K? And the NVidia drivers would support that under Linux (<- assumption). For example, this card ($220 at ME) claims to support four 4K monitors (DP, HDMI, DVI-D):<div><a href="https://www.memoryexpress.com/Products/MX64640">https://www.memoryexpress.com/Products/MX64640</a><br></div><div><br></div><div>Have you had trouble in the past, or is this just due diligence?</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Apr 6, 2018 at 12:52 PM, Gilles Detillieux <span dir="ltr"><<a href="mailto:grdetil@scrc.umanitoba.ca" target="_blank">grdetil@scrc.umanitoba.ca</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

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 (<span class="m_2095390661267624405myEmphasis">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="m_2095390661267624405myEmphasis">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.<span class="HOEnZb"><font color="#888888"><br>
