# Updating the display # File Naming Convention
There are compiled .tft files in the repo for basic and enhanced Nextion
displays of sizes 2.4", 2.8", 3.2" and 3.5". Please choose depending on the
model number printed on the back of the display.
The basic displays are denoted by a "T" as 7th character in the filename and
model number whereas enhanced displays have a "K" in that position. The actual
display size can be derived from the last two digits. The four digits in between
the characters refert to the diplay's resolution.
For example: A model number NX4832T035 represents a display with:
- a resolution of 320x480 pixels
- basic command set
- a screen size of 3.5"
