Thanks for pointing me in the right direction. The SDL library looks to be the easiest. I am concerned about the speed of my display. I am planning on trying the copy and also rewriting the code to use SDL and see if there is a noticeable speed difference. Thanks again for your help.

Thank you very much for the reply. Is there a graphics library that runs well on the Pi and can write to the frame buffers directly?

I have written a small program with simple graphics using C++ and OpenVg. I am using a 3.5" spi LCD. When I am running on my hdmi monitor the program runs as expected. However when I switch to the lcd everything seems to work as expected except my graphics from my program appear on the hdmi instead ...
