Renegade X in 2560x1440p resolution

[mc0il]

I don't have the 2560x1440 resolution option in the Settings/Video menu. 
Tried fullscreen and windowed. (i can maximize the window to fit my screen, but the window borders and my taskbar are limiting space)

I recall editing a config file to set a manual resolution or maybe there is a better way.

Appreciate any help, thanks!

You can also set that ingame via the setres command. For example if you wanted 1080p fullscreen, open console with f5 and type setres 1920x1080f
