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
