Re: Raspberry Pi Display Screen with Touchscreen Control Panel

Might be worth reading this thread, where support for HDMI and LCD at the same time is discussed/introduced.

Hi jamesh,

did any of the multiple framebuffer code made it into latest Raspbian release (2018-10-09)? If not, can you prepare files to test with latest version?
None of the code has been merged yet, I'll need to rebuild everything on the latest tree. Might be able to do in a few days.

Thanks for the input guys. I really appreciate that.
