At first the proper resolution (3840x1080) was not in the resolution option. Then after adding the following lines 3840x1080 resolution did appear in the option list.



sudo xrandr --newmode "3840x1080_60.00" 346.00 3840 4088 4496 5152 1080 1083 1093 1120 -hsync +vsync
sudo xrandr --addmode DP-1 "3840x1080_60.00"


After selecting 3840x1080 the actual resolution of the monitor remained unchanged. The resolution changes and fix automatically when DP-1 connection is pulled out and reconnected. All is good until the system is restarted or the monitor is waken from sleep. I also added the above line to .profile file so the starting resolution shows 3840x1080 but still the same problem. Finding no other solution I am just reconnecting DP-1 connection every time I start the the system and I have disabled monitor sleep mode.
