For a 40" monitor, you appear to have a very low resolution... I'm looking at buying a 39" that runs at 3840x2160, and 2560x1440 isn't uncommon for screens in the lower 30's.
Is it capable of upping the resolution a bit?
That said, if you are running any kind of *nix, you probably know how to, and it probably can't... so I'll just shut up now... 😉
