openSUSE: 13.2 x86_64
Display: ASUS PB287Q
Graphics: PNY Quadro K620
NVIDIA Driver Version : 340.93
Attempting to get a display and graphics upgrade up and running. The problem is that when I have only the new display connected using Displayport 1.2 (monitor configured for 1.2 operation) I have the following:
- Display output when BIOS running.
- Display output when KDM login running.
- When KDE desktop boots the monitor reports no DIsplayport signal and goes into a low power mode.
When I connect the old monitor (Samsung SyncMaster) that I want to retire (i.e. both old and new monitors connected); the KDE desktop boots OK and the new monitor (ASUS PB287Q) happily runs over the DIsplayport 3840x2160 @ 60Hz. The only monitor configuration I can find is in xorg.conf (see below):

The only monitor definition I can find is for the old Samsung SyncMaster (no automatic update for the new monitor); would I be correct in assuming that the lack of configuration information for the ASUS PB287Q is the reason for the loss of Displayport signal in the single monitor (PB287Q) boot scenario?
If this is the case what is the correct (automatic) way of converting the “xrandr --verbose” output into a new monitor definition? Is there another preferred mechanism for generating monitor definitions?
Which is the correct location for a new monitor definition, “xorg.conf” or “/etc/X11/xorg.conf.d/50-monitor.conf”? Obviously I would like any new monitor definition to survive any future package update.
Thank in advance for any answers.
