Friends tell me, monitor resolution. (Call of Duty)

here is the correct answer: open the config (config.cfg) and write the following there (if there are already such commands there, find them and replace them):
seta r_customwidth "1440"
seta r_customheight "900"
seta r_mode "-1"

r_mode should be set to - 1, only then the system checks the customwidth and customheight values.

the same with the multiplayer file config
