Statement of Volatility – Dell U3219Q Monitor

The purpose of this document is to certify that the Dell U3219Q 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 U3219Q 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 U3219Q monitor.

System EEPROM ST M24C32

Size 32Kbit

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 OSD settings

(ex. brightness, contrast, color) and the settings will

be stored into system EEPROM.

How is this memory write

protected?

Software write protected

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
