Hi there ...
Did you see my post here ... ?

Where I said ...
Run the game once ... then ... edit or add these lines in config.cfg for the original Call of Duty and uoconfig.cfg for United Offensive
These cfg files will be found in the Call of DutyMain folder and the Call of Dutyuo folder.
seta cg_fov "115" Set this to whaterver looks best for your widescreen resolution.
seta r_customheight "800" Set this to whatever res you want.
seta r_customwidth "1280" Set this to whatever res you want.
seta r_mode "-1"
So ...
Run the game once ... This is so that the game makes the cfg files that you need to edit.
Then find these files ...
config.cfg for the original Call of Duty and
uoconfig.cfg for United Offensive.
These cfg files will be found in the Call of DutyMain folder and the Call of Dutyuo folder.
Now ... edit the cfg files using Notepad or Wordpad.
The bits in
BOLD are the figures/entries you should have in your cfg files ... edit similar lines that are allready there or add the lines if they are not.
In your case just change the number for the ... seta r_customheight ... and ... seta r_customwidth ... to ...
seta r_customheight "1200"
seta r_customwidth "1920"
The FOV is probably best at 110 ... so ...
seta cg_fov "110"
Don't forget to change this line too ...
seta r_mode "-1"
If you still can't work it out ... please tell me more specifically which bit you are confused about and I'll do my best to help you further ... :D
