I have two monitors with different max. resolutions (2560x1440 and 1920x1080). In windows I am able to configure the max resolution for both monitors but in linux (manjaro, proprietary nvidia drivers and xrandr 1.5) is the resolution of the bigger one limited to 2048x1152. I read several questions/threads/articles how to add custom resolution via xrandr but none of these work for me. Here is my problem:
Output of xrandr:
Screen 0: minimum 8 x 8, current 3968 x 1152, maximum 16384 x 16384
DVI-I-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 disconnected (normal left inverted right x axis y axis)
DVI-I-2 connected 1920x1080+2048+0 (normal left inverted right x axis y axis) 478mm x 269mm
1920x1080 60.00*+
... skipped few lines ....
640x480 75.00 72.81 59.94
HDMI-0 connected primary 2048x1152+0+0 (normal left inverted right x axis y axis) 553mm x 311mm
2048x1152 60.00*+
... skipped few lines ...
640x480 75.00 59.94 59.93
DVI-I-3 disconnected (normal left inverted right x axis y axis)
I generate new custom resolution with cvt:
$ cvt 2560 1440 60
# 2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHz
Modeline "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
Now I want to create new resulution:
xrandr --newmode 2560x1440_60.00 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
Output of xrandr looks now like this:
Screen 0: minimum 8 x 8, current 3968 x 1152, maximum 16384 x 16384
DVI-I-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 disconnected (normal left inverted right x axis y axis)
DVI-I-2 connected 1920x1080+2048+0 (normal left inverted right x axis y axis) 478mm x 269mm
1920x1080 60.00*+

640x480 75.00 59.94 59.93

2560x1440_60.00 (0x313) 312.250MHz -HSync +VSync
h: width 2560 start 2752 end 3024 total 3488 skew 0 clock 89.52KHz
v: height 1440 start 1443 end 1448 total 1493 clock 59.96Hz
If I want now to add this resolution to output HDMI-0 I get following error:
$ xrandr --addmode HDMI-0 2560x1440_60.00
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 33
Current serial number in output stream: 34
In the past I was able successfully use this method to setup my monitors as needed without any problem on different pc (notebook + ext. monitor, both with the same resolution). I would really appreciate any suggestions.
