How can you use sim hub with the Waveshare Raspberry Pi 3.5 Inch Touch Screen TFT LCD (A) 320 * 480 for Raspberry Pi RPi / Raspberry Pi 2 Model B / Raspberry Pi 3 Model B?

Can I use it with this Raspberry Pi LCD Touchscreen Case?
I have had issues with one type of screen not working in the past. As long as the screen will be recognised by windows you will be fine. Just plug into your PC and then move the dashboard to that specific screen. It should autofill for you.
