This is just some quirk of how Toshiba chose to implement this
display, and it can be fixed with an altered modeline.

In xorg.conf, or a file in xorg.conf.d, you need an entry of
this format. Note that this is an example of the format, not the
right answer for you - among other things, I bet it's not
connected on HDMI.:

Section "Monitor"
    Identifier "Monitor-HDMI1"
    VendorName "LGD"
    ModelName "ULTRAWIDE"
    Modeline "2560x1080" 185.580 2560 2624 2688 2784 1080 1083 1093 1111 -HSync -VSync
    Option "PreferredMode" "2560x1080"
EndSection

Via xrandr instead, applying such a thing would look like this:

xrandr --newmode "2560x1080" 185.580 2560 2624 2688 2784 1080 1083 1093 1111 -HSync -VSync
xrandr --addmode HDMI1 "2560x1080"
xrandr --output HDMI1 --mode "2560x1080"

So that's the how. The what is best explained by this web page:

Which should be enough for you to work out the specific timings
needed to get this screen to work.
