Well, there is a surprising amount of cards that don't support 4k,
especially the lower cost ones.<br>
<br>
The issue with drivers is that the "built-in" X.org drivers that
come in their open source packages have good support for older
cards, but not always for the newer cards (which the 4k-capable ones
will tend to be). The X.org "nouveau" driver claims to support
GeForce GTX 200 and 400, but doesn't mention the GTX 1050 chipset in
the card you suggested.<br>
<br>
Using Nvidia's own Linux drivers has usually involved downloading
and installing kernel version-specific pre-compiled binary modules,
which stop loading after a kernel update.<br>
<br>
So, yes, due diligence because of trouble in the past.<br>
<br>
I've just read up on elrepo.org, though, which seems to package up
"kABI-tracking kmod drivers" which don't need to be recompiled for
each kernel update, and their repo includes nvidia drivers. So, that
may be something to look into. Trouble is some of the stuff that
turned up in my Google searches involved people struggling to get
those elrepo drivers working, so it still won't be quite as simple
and straightforward as it would be if I could get a 4k card that
works with the default X.org radeon or nouveau drivers.<br>
<br>
So, advice from someone who has gotten 4k video working under X.org,
with or without the elrepo drivers, would be appreciated.<br>

<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 text="#000000" bgcolor="#FFFFFF"> 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>
