Statement of Volatility – Dell U4919DW Monitor

The purpose of this document is to certify that the Dell U4919DW 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 U4919DW 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 U4919DW

monitor.

System EEPROM AT24C256C-SSHL-T

Size 256Kbits

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 settings (OSD)

How is data input to this

memory?

Controls the OSD menu and changes OSD

settings (ex. brightness, contrast, color settings)

and the setting will be stored into system

EEPROM.

How is this memory write

protected?

Software write protected
