Computer Monitors
Craig Hershberg
US EPA
2
Agenda and Goals for Today’s Meeting
• Present and discuss changes between the Draft 1 and Draft 2 specification
• Present an overview of the test data provided by manufacturers
• Discuss completion of the computer monitor test methodology
• Discuss Partner Commitments, including labeling of computer monitors
GOALS:
• Provide EPA’s rationale for the Draft 2 specification
• Gather industry feedback on Draft 2
• Outline next steps and a timeline for finalizing the Version 4.0 specification
3
Time-Frame for How We Arrived at Today’s Meeting
• July 1999: Monitor MOU Version 3.0 went into effect• April 2002: Computer monitor stakeholders meeting in
California. Collected feedback on Draft 1 Version 4.0 specification
• May 2002: European computer monitor stakeholders meeting in France
• June 2002 – February 2003: Test methodology development phase (EPA and industry)
• February – May 2003: Data collection and testing phase (EPA and industry)
• May – July 2003: Data analysis phase, and development of Draft 2 Version 4.0 specification (EPA)
• July 22, 2003: Stakeholder meeting to discuss Draft 2 specification
4
Highlights of the Draft 2 Specification
• Designed to be a performance-based specification– Does not differentiate based on technology (CRT, LCD, etc.)– Recognizes best performing monitors in the marketplace (in terms of
energy-efficiency)
• Based on test data voluntarily submitted to EPA by many manufacturers
• Includes detailed test methodology for how to test in all three modes
• Contains Tier 1 and Tier 2 maximum allowable power consumption for On, Sleep, and Off modes
• Allows various screen sizes, technologies, and brand-names of computer monitors to qualify under the Tier 1 requirements
• Establishes partner commitments (to be discussed later today)– Labeling– Grandfathering
• Provides extended effective dates to accommodate the removal of grandfathering

Overview of Data Submitted to EPA by Manufacturers
6
Overview of Data {1}
• 2 rounds of voluntary testing– February - April and May - June
• 19 manufacturers represented (15 brand-names and 4 additional OEMs)– 49 CRTs, 40 LCDs, 1 Plasma display
• 87 models included in analysis (3 represented models excluded due to testing at incorrect voltage/frequency combination)

Overview of Data {2}
• For perspective: Only 265 computer monitor models in 2002 with retail sales over 100 units (data from NPD)
• 15 top selling models from Q1 2002 represented– 10 out of top 20 selling CRTs– Top 5 selling LCDs
• Data represents 15” to 24” models and one 30” model• Manufacturers encouraged to submit testing data on
latest, highest resolution models – Many models EPA has test data for are highlighted as “NEW”
on manufacturer Web sites
• Several models from data set reviewed in June 2003 issue of Consumer Reports
8
Changes to Draft 2 from Draft 1
9
Several Minor Changes to Definitions
• Operational mode definitions reordered and clarified– Now listed from highest to lowest power consumption– Examples of “a request from a user” are included
• Does Version 4.0 effectively differentiate between computer monitors and televisions?– “A commercially available electronic product with a display
screen….capable of displaying output information from a computer via one or more inputs, such as VGA, DVI, and/or IEEE 1394.”
– Specification attempts to differentiate TVs and computer monitors based on how they are marketed and sold
• Is it clear as to what can and cannot qualify under Version 4.0, or is further discussion needed?

Energy-Efficiency Requirements
Tier 1 Requirements• On Mode:Y=33X+30• Sleep Mode: 4 watts • Off Mode: 2 watts • Effective Date: November 1, 2004
Tier 2 Requirements• On Mode: If X<1 megapixel, then Y=20; if X>1
megapixel, then Y=26X-5• Sleep Mode: 2 watts • Off Mode: 1 watt• Effective Date: November 1, 2005
12
On Mode Requirement Tier 1
Set at Y=33X+30• Y = watts (rounded up to nearest whole number)• X = number of megapixels (in decimal form)• 60% of all monitors in EPA’s data set meet Tier 1

Example:
A computer monitor with 1,920,000 pixels
(resolution of 1600 x 1200) has maximum power
consumption allowance of 94 watts
33(1.92)+30=93.36 or 94 watts
13
Sample Tier 1 On Mode Values
Resolution* Total Pixels Maximum Power Allowed
Tier I
640 x 840 307,200 41 watts
800 x 600 480,000 46 watts
1024 x 768 786,432 56 watts
1280 x 1024 1,310,720 74 watts
1600 x 1200 1,920,000 94 watts
1800 x 1440 2,592,000 116 watts
2048 x 1536 3,145,728 134 watts
* CRT = Preferred pixel format with highest resolution intended to be driven at 75 Hz LCD = Native Resolution
14
Sleep and Off Mode Requirements Tier 1
• Sleep Mode: 4 watts– One Sleep Mode requirement
– References to Sleep Mode Default Time have been removed from the computer monitor specification
– 30-minute default time for Sleep Mode defined in computer agreement
• 60-minute default time for Deep Sleep Mode not applicable
– 87% of all monitors in EPA’s data set meet Tier 1 in Sleep Mode
• Off Mode: 2 watts– 78% of all monitors in EPA’s data set meet Tier 1 in Off
Mode

On Mode Requirement
Set at: If X<1 megapixel, then Y=20; if X>1 megapixel,then Y=26X-5
• Y = watts (rounded up to nearest whole number)• X = number of megapixels (in decimal form)• 22% of all monitors in EPA’s current data set meet Tier
2 in On Mode
Example:• A computer monitor with 786,432 pixels (resolution of
1024 x 768) has maximum power consumption allowance of 20 watts
• A computer monitor with 1,920,000 pixels (resolution of 1600 x 1200) has maximum power consumption allowance of 45 watts
26(1.92)-5=44.92 or 45 watts
20
Sleep and Off Mode Requirements
• Sleep Mode: 2 watts– 63% of all monitors in EPA’s current data set
meet Tier 2 in Sleep Mode
• Off Mode: 1 watt– 57% of all monitors in EPA’s current data set
meet Tier 2 in Off Mode
– Will harmonize with FEMP
– Will follow 1-watt level that many ENERGY STAR specifications are moving towards

Tier 2 Qualifying Models: All Operating Modes
• 14% of all monitors from EPA’s current data set qualify for ENERGY STAR– Tier 2 provided as an “energy-efficiency
roadmap” for manufacturers – will be revisited prior to taking effect, to ensure it is still applicable to the marketplace at that time

Big Picture: Potential Savings
Projected Savings by 2010 =• Energy: approximately 246.7 billion kWh• Dollars: approximately $14 billion• CO2: approximately 37.6 billion lbs, or equivalent to
taking approximately 2.9 million cars off the road
Per Unit Savings =• Energy: Up to 147 kWh annually• Dollars: Up to $12 - 24 annually
Notes: Savings (1) Include On, Sleep, and Off Modes, and (2) Assume CRTs are replacedwith a mix of ENERGY STAR qualified LCDs and CRTs, with increases in market penetrationgoing to LCDs.

Removal of Grandfathering Language
• EPA has removed grandfathering language from ENERGY STAR specifications– Delivers on consumer expectations of high
efficiency performance and energy savings– Ensures that ENERGY STAR's ability to
differentiate more efficient products is not undermined by high percentages of labeled products qualifying at less stringent performance levels
• EPA plans to accommodate manufacturers by extending effective dates of the Version 4.0 specification
