DS-D40CXV21 | SCREEN D40BC04 GML GM 3.2.0

2 1 minute read

SCREEN_D40BC04_GML_GM_3.2.0 appears to be a Hikvision LED display firmware/software build string, likely related to the receiving card or display controller firmware version 3.2.0. I could not find an official public firmware package for this exact build name on Hikvision’s public portal.

Usually these strings mean:

SCREEN = LED display firmware
D40BC04 = board/controller model
GML_GM = chipset/platform variant
3.2.0 = firmware version

Official Hikvision firmware downloads are available here:

Hikvision Firmware Download Center

Hikvision Display Products

Important:
Using the wrong firmware on Hikvision LED/display boards can brick the controller or cause boot loops. Community reports also mention firmware mismatch problems with regional/OEM variants.

To identify the correct file, send:

Backside board photo
Controller card photo
LED module photo
Exact error/problem
Current firmware screenshot
Whether it uses Novastar / Colorlight / Hikvision controller

Then I can help locate:

Correct firmware
Upgrade method
USB/serial update process
Recovery file
Matching receiver card software
Configuration file (.rcfg / .cfg) if needed.
