i had the same problem but with different resolutions (1080p monitor, want to play csgo 1680x1050 stretched)
but i want fullscreen windowed and i despise alt tabbing.
my solution was to install a program called HRC.exe which lets me select 2 resolutions and switch between them using a hotkey.
my setup for the program is like this: http://i.imgur.com/QTHJ1YB.jpg
and i just press ctrl+shift+[ before i launch csgo, and then when i'm finished i press ctrl+shift+] to return to 1080p
last thing you need to do is make your video.txt strictly read only because if you change resolutions then launch the game it will restore the default video settings, and i found that just ticking read only in video.txt's properties doesn't prevent the game from changing the video settings.
so i use easyfilelocker to lock the file from being altered. here are my settings for easy file locker: http://i.imgur.com/JrreWrd.jpg
it's pretty easy to use, just add video.txt to it and set it like this: http://i.imgur.com/VoSCYuB.jpg
i have a shortcut for easyfilelocker in my startmenu so i can disable the lock if i need to change something in my video settings (doesn't happen often)
anyways hope this was helpful.

This is probably my best bet. Thank you :)
