Dell U2422H Statement of Volatility
Summary
The Statement of Volatility for Dell U2422H Monitor certifies that no input video data is saved, retained, or reproduced after power removal. The monitor contains non-volatile memory ICs including system EEPROM (256Kbit for OSD settings), HDMI EDID EEPROM (2Kbit), system flash (32Mbit for firmware), and USB hub flash (4Mbit). Volatile components like DDR4 2667MHz memory lose data immediately upon power loss, while secondary power loss from coin-cell battery removal affects system configuration a

Statement of Volatility – Dell U2422H 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 U2422H 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 U2422H 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.

CAUTION: All other components on the system board lose data if power is removed from the system. Primary power loss (unplugging the power cord and removing the battery) destroys all user data on the memory (DDR4, 2667 MHz). Secondary power loss (removing the on-board coin-cell battery) destroys system data on the system configuration and time-of-day information.

Frequently Asked Questions
What is the primary function of volatile memory in this monitor?
Volatile memory loses its data immediately when power is removed.
Which type of memory retains data after power loss?
Non-volatile (NV) memory ICs retain their data even after power has been removed.
What happens if I unplug the power cord from the monitor?
Primary power loss destroys all user data on the system memory (DDR4, 2667 MHz).
Which component stores the On-Screen Display settings?
The System EEPROM (U29) stores system setting data for the OSD.
