Statement of Volatility – Dell U3419W Monitor
The purpose of this document is to certify that the Dell U3419W monitor will not save, retain, or
reproduce a signal to any internal or external component after power has been removed and reapplied
to the unit.
The Dell U3419W monitor contains both volatile and non-volatile (NV) memory ICs. Volatile memory(s)
lose their data immediately upon removal of power. Non-volatile memory ICs continue to retain their
data even after the power has been removed. However, no input video data is written into these
memory ICs during operation.
List below contains volatile and non volatile memory ICs used in the Dell U3419W monitor.
System EEPROM
ST M24C16
Size
16Kbit
Type [e.g. Flash PROM, EEPROM] EEPROM
Volatility
Non-volatile
Can user programs or operating
system write data to it during
normal operation?
OSD setting: Yes
Purpose
Storage of system setting (OSD)
How is data input to this
memory?
Controls the OSD menu and changes the OSD setting (ex.
brightness, contrast, color settings) and the setting will be
stored into system EEPROM.

HDMI EDID EEPROM ST M24C02
Size
2Kbit
Type [e.g. Flash PROM, EEPROM]
EEPROM
Volatility
Non-volatile
Can user programs or operating
system write data to it during
normal operation?
No
Purpose
Storage of HDMI EDID
How is data input to this
memory?
HDMI EDID is embedded in the firmware, and copied to
EEPROM after F/W programming.
(or via customized EDID tool)
