How to update the display

Some features, such as G-code preview, need updated firmware to work on some DACAI and TJC displays. Custom icon assets such as Giadej icon set are only supported by DWIN and DACAI displays.

If you have the stock icon set, in principle you do not need to update the display to use this firmware, only some TJC display units need a firmware update to boot properly. Creality currently provides several types of display units with its Ender-3 V2/S1/Neo printers:

DWIN display, the original display unit, it supports all firmware functions.

DACAI display, some versions need updated firmware to enable G-code preview

SYNWIT (VIEWE) display, initially unsupported due to incompatibilities with QR-codes (removed in latest firmware version) some users report problems with this screen, but now seems that it is working without issues.

TJC display, currently this display needs a special compile to show numeric data in the tramming wizard and in the mesh viewer, some displays need updated firmware to enable G-code preview and boot properly, more info: TJC issues.

The DWIN_SET display firmware / icon assets only apply to the DWIN display, for the DACAI screens, you should use the private display firmware / icon assets.

Display firmware, boot image and icons compilations

The display assets compilations in this page are compatible with Professional firmware. Each firmware can have its own compatible icon set.

How to install

Get an µSD card of 8GB or less.
Format the µSD card MBR, FAT32 and with a 4 KB sector size
Copy the DWIN_SET(DWIN), private(DACAI) or TJC_SET (TJC) folder in the Root of SD
Turn off your printer
Disconnect and disassembly the screen unit
Install the µSD card into the slot of the screen unit
Reconnect the screen to the printer
Turn on the printer and wait for the display to change color from blue to orange
Verify that the screen assets were updated
Turn off the printer and remove the µSD card from the screen unit
Reassembly the screen unit

If you weren't able to update the display, verify the format of the µSD Card (MBR, FAT32 and allocation unit of 4096 bytes) and the CRC of the files.

Be sure to leave only the DWIN_SET or private folder at the root of the card.
