Have three XB271HU, one has slightly different specifications

I am having trouble enabling 3x1 surround at 144Hz. Nvidia drivers only show the option for 120Hz. Turns out I have monitors with different specifications when viewed with MonInfo.

 

Monitor 1 has a different horizontal scan range compared to monitors 2 and 3 at 144Hz. I believe this is the root cause for not being able to enable 144Hz on 3x1 surround. All monitors are from the same batch, November 2015.

 

Troubleshooting steps taken:

1) Tried 2x1 surround on monitors 2 and 3, 144Hz option available.

2) Tried 2x1 surround on monitors 1 and 2, 144Hz option not available (highest is 120Hz).

3) Tried EDID override on monitor 1, no display.

 

As such, I am unable to run 3x1 surround at 144Hz. What can I do? Should I also bring this up to Nvidia?

 

For the record, monitor 1 is a replacement unit from the service centre as the previous unit had a severe yellowish tint. The previous unit didn't have problems with 3x1 surround at 144Hz.

    I guess you need to send the monitor back which seems incapable of running in 3x1 144hz.
