The G2 is around 22 pixels per degree. But you lose a large chunk of resolution due to bilinear resampling. So a 22 degree virtual screen would be around 1320px wide, but have a lower usable resolution. Since people did develop with multiple 1280x1024 monitors, this is a usable resolution with the right setup.
