@ The Coolest. use refresh force to force 75hz in games.

download it select the active monitor 2209wa, find 1680 x 1050 and change the frequency to 75hz, click apply, then yes, then OK. you can close and delete the program if you wish. Now fire up any game and it should stay at 75hz.
EDIT- IT IS POSSIBLE WITH DVI TO RUN AT 75HZ WITH 190.38!
There is just a couple of intermediate steps compared to before
what you have to do is after you install and restart the system. go into the nvidia control panel. select a resolution OTHER than 1680x1050, say 1280x1024 and run at that. Now click add resolution, check enable resolutions this monitor not exposed. click OK. then EXIT the nvidia control panel.
Open nvidia control panel back up. click add resolution, Create a custom resolution of 1680x1050 at
72 (SEVENTY TWO) HZ at a bit depth of
16 BIT, make sure you set the timings to manual, and use the same timings as before in post 19, but instead of 75hz and 32 bit your doing 72hz and 16bit. click test then click OK.
Select the 1680x1050 resolution and select 72hz and click apply. you should now be at 1680x1050@72hz@16bit.
NOW click on create a custom resolution again CLICK THE RED X next to 1680 x 1050 @ 60hz (32bit) at the top of the box under the custom area.
LASTLY click create a custom resolution and use the exact numbers as outlined in POST 19 to fill all the timings in. click test then click yes then click OK. You should now be running at 1680x1050 at 75hz with 32bit depth.
LMK if you guys got it, it takes a lil tinkering to get it to do it, but it is definitely possible no doubt.
