If you have a Nvidia card, then try DSR. I'm not sure if it will work, but it is worth a try.

I was able to set it manually in:
USERPROFILE%\Documents\My Games\UnrealEngine3\MonkeyGame\Config\MonkeyEngine.ini
[SystemSettings]
ResX=2560
ResY=1440

I also applied some fixes described here and run it at 144fps:

If DSR works like AMDs VSR, it probably wont work.

Setting ResX and ResY didn't seem to change anything for me. But open MonkeyGame.ini in the same directory, find the resolutions near the bottom, and add this line:
and you will be able to select it in game.

where do u put that ?? i cant find anything about those command in monkeygame.ini.....

In mine, there’s a bunch of m_ResolutionValues= lines near the bottom, one for each resolution selectable in the game.

oh dear god.... finally.... i found it.... thx, dude....

but, too bad.... with 1440p, some cutscene movement camera become buggy.... and if alt+tab to desktop, make the game = crash to desktop.... and if iam playing again, resolution back to 1080p... changed to 1440p , crash to desktop....

Made the changes, but the game never remembers the resolution settings and defaults back to 1920x1080, so does this game not support dsr?
