TFT DISPLAY
The very first time you'll start the Ender-3 V3 it will run a self-test which will last for quite a bit (input shaping takes the longest).
Typically, the main menu of the printer shows temperatures of both the print bed and the nozzle.
Second screen allows the end user to move the print bed and the extruder, extrude and retract filament and adjust cooling.
From the folder tab you can browse between local and USB 3D samples and check printing history.
Settings like screen brightness, screen off timeout, language, self-check, account information, time zone, Creality cloud, log export, online firmware update check, reset, expert mode features, information about the printer, network and camera features (camera is sold extra) are all placed in the next tab.
From the last tab you can check the frequently asked questions (FAQ), read the online manual, check the error history and upload logs (probably to Creality for support, didn't check that).
