Re: Pi4 + 7in touch + hdmi

The new driver will detect your DSI 7in + HDMI monitor and show the desktop on both. Use the screen configuration tool to align them as needed. The legacy driver also supports dual display but you need to make some steps yourself as it's not working out of the box. See here for a how to - https://w...

Re: CM3 Plus and WiFi/BT CYW43455

Your best bet is dump the dt-blob and look at pi3+ it will give you clues.
I have done a lot with cm3.
I am a hardware engineer
And don't worry about the 50mhz sdio.. hdmi dsi & csi are much much faster and need impedance control.
