How to display oF programs to TFT displays which is connected to RasPi3?

Hi, I’m using raspberryPi3.
I would like to display oF programs to TFT display.
I’ve already confirmed working “polygonExample” on HDMI output.
Also, I’ve already confirmed rendering RasPi Desktop on TFT display.
I don’t know why the example don’t render on TFT display.
Thanks for your help in advance.
