Try to drop your resolution to 800x600 or preferably 640x480. NTSC's native resolution is roughly equal to VGA (640x480), so it will be the clearest at that size. Once you can read the screen again, you'll want to venture into the nVidia control panel and adjust your flicker rate, overscan and other settings to clear the picture up as best as possible.
That said, even with decent settings and the right resolution, you can still expect any computer output to NTSC to look absolutely fugly. Some video cards will handle it better than others, but the fundamental problem of trying to adapt a higher quality and resolution video source to a lower one remains.
Even for temporary use, you'd probably be better off trying to Craigslist up a cheap CRT for $20 or $30.
