32:9 Monitor Not Using Correct Resolution

When using xrandr, this is what comes out if the monitor is set to 3840x1080:

Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 32767 x 32767
HDMI-0 disconnected (normal left inverted right x axis y axis)
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 connected primary 3840x1080+0+0 (normal left inverted right x axis y axis) 1193mm x 336mm
   3840x1080    119.97*+ 239.97    59.97  
   5120x1440    239.76   120.00    59.98 

Interstingly enough, when I set it to the monitor's native resolution, 5120x1440, this is what comes up:

Screen 0: minimum 8 x 8, current 5120 x 1440, maximum 32767 x 32767
HDMI-0 disconnected (normal left inverted right x axis y axis)
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 connected primary 5120x1440+0+0 (normal left inverted right x axis y axis) 1mm x 1mm
   3840x1080    119.97 + 239.97    59.97  
   5120x1440    239.76*  120.00    59.98  

This has been causing a very weird issue in my games, such as TF2:

To try and fix this, I have tried to create a 10-monitor.conf file with the modeline information, but that has not worked.
Since then I have been trying to either set the 5120x1440 as preferred or remove the 3840x1080 entirely, but nothing has helped so far. Any help would be appreciated.

Re: 32:9 Monitor Not Using Correct Resolution

Just an update to what I have been researching on my own.
Someone mentioned creating a custom EDID. While looking into this, another user on the forms requested to send the txt file from this command:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

In doing so, I got this.
I saw something in there when searching for 3840 about it being the resolution preferred, then being changed to 5120x1440. At least, that is what I think it is saying.

Am I going on the right track in fixing this dilemma?
