Hi, Distribution: openSUSE 42.2 Beta, Kernel: 4.4. The box is a Dell
Precision T7500 with an nVidia Quadro 4000 card and a displayport
connected iiyama B2783QSU 2560x1440 monitor identified as DP-1.
Problem: The monitor is detected as 1920x1080 and not 2560x1440. See Xorg
log file at http://rogerprice.org/Xorg.0.log . There is no file
/etc/X11/xorg.conf and in the directory /etc/X11/Xorg.conf.d/ the files
50-device.conf, 50-monitor.conf and 50-screen.conf contain comments only.
My attempted repair failed:
I used gtf to calculate a 2560x1440_60 mode line
Modeline "2560x1440_60.00" 311.83 2560 2744 3024 3488 1440 1441 1444 1490 -HSync +Vsync
and I then used commands
xrandr --newmode 2560x1440 311.83 2560 2744 3024 3488 1440 1441 1444 1490 -HSync +Vsync
xrandr --addmode DP-1 2560x1440
xrandr --output DP-1 --mode 2560x1440
The result is that windows on the screen seem to increase in size slightly
and flow off the screen. The system tray normally at the bottom of the
screen has disappeared. More precisely, command xrandr -q reports:
Screen 0: minimum 320 x 200, current 2560 x 1440, maximum 16384 x 16384
DVI-I-1 disconnected (normal left inverted right x axis y axis)
DP-1 connected 2560x1440+0+0 (normal left inverted right x axis y axis) 597mm x 336mm

1920x1080 60.00
1600x1200 60.00
1680x1050 59.88
1600x1000 60.01
1600x900 60.00
1280x1024 75.02
1440x900 59.90
1024x768 75.03 60.00
800x600 75.00 60.32
640x480 75.00 59.94
2560x1440 60.00*
DP-2 disconnected (normal left inverted right x axis y axis)
but command xvidtune -show reports:
"1920x1200" 154.00 1920 1968 2000 2080 1200 1203 1209 1235 +hsync -vsync
I'm not sure if I'm looking at a bug or if this is just noob confusion.
Any advice or suggestion would be much appreciated.
Roger

I think you want the reduced blanking modeline:
$ cvt -r 2560 1440
# 2560x1440 59.95 Hz (CVT 3.69M9-R) hsync: 88.79 kHz; pclk: 241.50 MHz
Modeline "2560x1440R" 241.50 2560 2608 2640 2720 1440 1443 1448
1481 +hsync -vsync
This matches your monitor's detailed timings:
[ 55.220] (II) NOUVEAU(0): Supported detailed timing:
[ 55.220] (II) NOUVEAU(0): clock: 241.5 MHz Image Size: 597 x 336 mm
[ 55.220] (II) NOUVEAU(0): h_active: 2560 h_sync: 2608 h_sync_end
2640 h_blank_end 2720 h_border: 0
[ 55.220] (II) NOUVEAU(0): v_active: 1440 v_sync: 1443 v_sync_end
1448 v_blanking: 1481 v_border: 0
Not sure why a 2560x1440 modeline isn't being advertised in EDID -
perhaps the monitor is in some "safe" setting where that's not
reported? Might have to flip it into DP 1.2 mode or something.

I tried the reduced blanking modeline, but the 1920x1080 format persisted.
So I then replaced the display port cables with the cables labelled "DP
V1.2" supplied by iiyama with the monitors. This fixed the problem. I now
have 2560x1440R on two iiyama monitors. I was most agreably surprized
that the nouveau driver automatically placed DP-2 to the right of DP-1 to
form a 5120x1440 surface. Very polished execution by nouveau!
Thanks for your help, Roger
