Hi Nino,
There is a later driver upgrade for nvidia cards, nvidia-361, in the
repositories. in terminal try:
sudo apt-get update && sudo apt-get install nvidia-361
sudo reboot, and see if the new driver provides the resolution that
you'd like.
***
Unlike other commenters in the thread, I don't see why an upgrade to
16.04 would be undesirable. I'm running 16.04 on my system. I haven't
had any problems, save one broken dependency which later resolved itself
during an automatic update. If you're confident with terminal commands,
you should be able to fix the odd broken dependency if one even appears.

Jordan,
FYI I got a videocard specifically to support this system,
a GeForce GTX 960; the driver is 352.79.
According to the specs, this card supports the monitor that
I can tell. I don't know the differences between the drivers.

Hi Nino,
which videocard are you using? Is it an integrated video chip system
(ie. intel), or a video card in the video graphics slot?
Maybe two scenarios are possible.
1) Perhaps your video card does not fully support display port at
that resolution. In that case you will need a new video card capable
of this task. If you are using an integrated graphics system, now
might be the time to get an external graphics card suited to the
setup you would like to have.
2) Perhaps your drivers are old, and not supportive of what you'd
like to do. Certain drivers, like the nvidia series, are available
by repository and are frequently updated. Others might be available
by ppa (search sourceforge for a possible ppa).
Good luck,
Jordan

Hi All,
I got myself qn ASUS PB287Q 4 k monitor with 3840x2160 pixels, which
I'm
using together with an older but still nice ACER X243W 1920x1200
monitor.
The ASUS can connect through a displayport, which allows it to
refresh at a
60 Hz rate, and an HDMI port which allows only 30 Hz (apparently).
The problem is: the connection through a displayport is plug-and-play
(I've been told), so that my computer Xubuntu 14.10) notices that
something
is amiss, and it switches over to the remaining screen. Something
similar
happens when I forget to log out: tihe system hits some timeout, the
monitor turns off, and the display goes to the smaller screen.
I could decide to use the HDMI connection, but then the mouse crawls
across
the screen with little jumps, a very irritating sight.
I could perhaps connect through a second HDMI connection to speed
things
up. But, what I'd wonder about is: can you turn off the
plug-and-play thingie
so that things stay alive the way I like them?
Any other suggestion for getting this monitor under control?
Thank you,
Nino
