Because of limitations of how tvs work. Tvs only accept 24hz and 60hz signals.
(120hz and 240hz tvs add in between frames, they do not accept native 120hz or 240hz signals, nor does HMDI support those frequencies)
24hz is for movies, 60hz for everything else. If you don't want awful screen tearing or inconsistent motion (judder), games only have the option to run at 60fps, 30fps, 20fps, 15fps, 12fps (60 divided by a whole number)
If you want 45fps, you need a pulldown patern like A,B,C,C, D,E,F,F, repeat every 3rd frame twice. That's not going to help since you still need to produce the first 3 frames in 1/60th of a second, then get a little break before the 4th frame. (Or store the frames ahead of time, which will create input lag)
With HMDI 1.4b (not finalized yet) you should be able to send a 120hz signal to the display, which you can divide by 3 to get to 40fps.
It would be nice if we can get rid of the fixed hz requirement for displays. It's all digital now, it would make more sense for a display to wait for a frame instead of updating at a fixed refresh rate. The times of an actual electron beam scanning a crt tube are long gone.
