Dell E2020H Monitor - Statement of Volatility
Summary
This Statement of Volatility document certifies that the Dell E2020H monitor does not retain video signals in memory after power removal. It details the volatile and non-volatile memory components used in the monitor, including System EEPROM for OSD settings, VGA EDID EEPROM for display identification data, and System Flash ROM for firmware storage. The document specifies memory types, sizes, write protection mechanisms, and data retention characteristics. Designed for security professionals, government agencies, and organizations requiring memory volatility certification for compliance with data security standards and regulations.

Statement of Volatility – Dell E2020H Monitor
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The purpose of this document is to certify that Dell’s E2020H 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 E2020H 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 Dell E2020H monitor.

Frequently Asked Questions
What happens to data when I unplug the monitor?
The Dell E2020H will not save, retain, or reproduce a signal after power is removed.
Which memory types lose data instantly upon power loss?
Volatile memories lose their data immediately when power is removed.
Can user settings be modified and saved on the monitor?
Yes, system settings (OSD) are stored in the System EEPROM and can be controlled via the OSD menu.
Is the VGA EDID memory user-writable or protected?
No, user programs cannot write data to the VGA EDID. It requires hardware and software protection.
