Set up your own Pocket Computer! All small GPIO screens for the Raspberry Pi go through a very similar process to set up. The Waveshare 3.5 Inch LCD 480x320 is the perfect example to demonstrate how.

There is a whole range of Sub-4 Inch Displays that attach directly to the GPIO pins of Raspberry Pi Palm-Sized Computers. Many of them are touch devices and increase the usability of your Raspberry Pi whilst making almost no size sacrifices. For scenarios where a high frame rate is valuable/desired, such as playing retro games, whilst keeping the same form factor the display methods I would direct you to use is a IPS HDMI screen as you will get fantastic high FPS results straight away. The HDMI ports on the Raspberry Pi boards are very powerful and more effective at transferring video data than the GPIO pins. But for situations where you only desire a simple UI with touch then these small displays are perfect. The GPIO also offers a very rugged sturdy connection and together make for a compact nugget of practical computing power. The process will be done in this guide so that you do not need to access the Raspberry Pi headless. This is a much easier way to approach setting up a Raspberry Pi system with a GPIO display for beginners but you can definitely do this process remotely. If you want to squeeze out some extra performance from your screen by diving into the configuration files.
