This LCD screen is easy to set up by following the electronic instructions on the Revain product page or the paper instructions that came with the product (using a pre-programmed GitHub package). Some app splash screens extend beyond the LCD, but as far as I can tell, any running app can be resized to fit the 3.5-inch screen. I mainly use this as a viewer to view a printed Python script. States without an external monitor or an active Putty session, but I also see it useful for gaming. I also plan to use it to show some statistics about industrial control processes (in graphical form, with a package like Ignition by Inductive), so as well an additional display terminal in the factory server room would wall mount the Pi This screen is a very fun addition to the Pi 4 and I am pleased with how well it performs.
