21B) Operational Modes:

22231) On Mode: The mode in which the Display has been activated, and is providing the primaryfunction.

24252) Sleep Mode: A low-power mode in which the Display provides one or more non-primary
protective functions or continuous functions.

26
27
28

Note: Sleep Mode may serve the following functions: facilitate the activation of On Mode via
remote switch, Touch Technology, internal sensor, or timer; provide information or status
displays including clocks; support sensor-based functions; or maintain a network presence.

29
30
31

3) Off Mode: The mode where the Display is connected to a power source, produces no visual
information, and cannot be switched into any other mode with the remote control unit, aninternal signal, or an external signal.

32
33

Note: The Display may only exit this mode by direct user actuation of an integrated powerswitch or control. Some products may not have an Off Mode.

34
35
36

C) Visual Characteristics:
1) Ambient Light Conditions: The combination of light illuminances in the environment
surrounding a Display, such as a living room or an office.

5) Native Vertical Resolution: The number of physical lines along the vertical axis of the
Display within the visible area of the Display.
Note: A Display with a screen resolution of 1920 x 1080 (horizontal x vertical) would have a
Native Vertical Resolution of 1080.
6) Screen Area: The visible area of the Display that produces images.
Note: Screen Area is calculated by multiplying the viewable image width by the viewable
image height. For curved screens, measure the width and height along the arc of the
Display.
D) Additional Functions and Features:

641) Bridge Connection: A physical connection between two hub controllers (i.e., USB, FireWire).

65
66

Note: Bridge Connections allow for expansion of ports typically for the purpose of relocating
the ports to a more convenient location or increasing the number of available ports.

67
68
69
70
71
72

2) Full Network Connectivity: The ability of the Display to maintain network presence while in
Sleep Mode. Presence of the Display, its network services, and its applications, ismaintained even if some components of the Display are powered down. The Display canelect to change power states based on receipt of network data from remote network devices,
but should otherwise stay in Sleep Mode absent a demand for services from a remote
network device.

73
74

Note: Full Network Connectivity is not limited to a specific set of protocols. Also referred toas “network proxy” functionality and described in the Ecma-393 standard.

75
76
77
78
79

3) Occupancy Sensor: A device used to detect human presence in front of or in the areasurrounding a Display.
Note: An Occupancy Sensor is typically used to switch a Display between On Mode andSleep Mode by detecting human presence or a combination of human presence and asignaling device such as Bluetooth device.

81
82

Note: In response to a stakeholder query in the Version 7.1 ENERGY STAR display specification, EPA is
proposing a minor clarification to the definition of Occupancy Sensor noting that a combination of humanpresence and a signaling device could be used to switch a Display between On Mode and Sleep Mode.

83
84
85

4) Touch Technology: Enables the user to interact with a product by touching areas on the
Display screen.

86875) Plug-in Module: A modular plugin device that provides one or more of the following functions
without the explicit purpose of providing general computing function:

165
166
167
168
169
170

Note: As in the recent Version 8.0 Television specification, EPA is considering including a requirementthat the Display alert the user that energy consumption will increase when selecting a Preset Picture
Setting that does not have ABC enabled by default or when more energy consumptive features areactivated, such as HDR upscaling. EPA considers that such requirements may help consumers better
understand the energy impacts of Displays when selecting non default picture settings and functions.

171
172
173
174
175
176

EPA seeks data that reflects frequency with which Displays leave the default setting or other informationthat would shed light on the frequency of displays operating outside of the default mode. EPA also seeks
data regarding the use of HDR upscaling and other features that increase energy use that are not foundin the default mode, including the prevalence of this feature, the frequency of its use, and how it isactivated. Lastly, EPA seeks feedback on the persistence of energy saving features like ABC whenscreen brightness and contrast ratio may be manually adjusted.

Note: Based on a preliminary assessment of 2017 shipments, EPA estimates that market share for
ENERGY STAR monitors could be as as high as 90%. As such, EPA considers its dataset of ENERYSTAR certified models to be representative of the market. In addition, the trend towards higher
efficiencies reflected in the data represents an opportunity for the ENERGY STAR program to further
differentiate among the highly efficient monitors on the market, helping to ensure that the ENERGY STARlabel remains an effective tool for consumers. With this Draft 1, EPA analyzed the ENERGY STARdataset of 776 unique models, and is proposing energy requirements that recognize a diverse selection ofmodels across all common sizes from 23 monitor brands. EPA continues to propose an allowance forresolution, as a higher resolution, all other things being equal, requires additional power in On Mode.
Regression analysis of monitor On Mode power indicates that for every megapixel of screen resolution,
the Monitor uses 1.3 W power on average. Therefore, EPA proposes lowering the 6.13 kWh per
megapixel allowance in Version 7.1 to 3.99 kWh, which is roughly equivalent to 1.3 W per megapixel in
On Mode. EPA proposes an area coefficient of 0.123 kWh per square inch for all size categories. Within
the TEC limit, an allowance for Sleep Mode is included, roughly equivalent to dataset average Sleep
Mode power demand of 0.25 W. EPA’s data package including the ENERGY STAR Version 7 dataset
used to develop these levels and associated scatter plots accompanies this proposal. EPA welcomes
feedback on this proposal.

For all Monitors, Calculated TEC (ETEC) in kWh shall be less than or equal the calculation of
Maximum TEC (ETEC_MAX) with the applicable allowances and adjustments (applied at most once)

0.15 × 𝐸𝑇𝐸𝐶_𝑀𝐴𝑋

234
235
236

Note: A model supporting greater than 99% of the sRGB color space translates to 32.9% of CIE LUV
and a model supporting greater than 99% of Adobe RGB translates to 38.4% of CIE LUV.

237
238
239
240
241
242
243
244
245

Note: Given technological advances and trends reflected in the dataset, EPA proposes revising theallowances for Enhanced Performance Displays. For EPD models with Color Gamut support of 32.9% of
CIE LUV or greater, the allowance has been decreased from 15% to 5% of the 𝐸𝑇𝐸𝐶_𝑀𝐴𝑋 . For models
supporting Color Gamut of 38.4% of CIE LUV or greater, the allowance has been decreased from 65% to
15% of 𝐸𝑇𝐸𝐶_𝑀𝐴𝑋 . Of the total 776 monitor models, 92 and 17 monitors qualify for EPD1 and EPD2
allowances, respectively. For greater simplicity in the expression of the requirements for EEP, EPA
proposes to apply the allowance to the entirety of 𝐸𝑇𝐸𝐶_𝑀𝐴𝑋 (under Version 7.0, the resolution allowance
was first subtracted from 𝐸𝑇𝐸𝐶_𝑀𝐴𝑋 , reducing the size of the EEP allowance). This proposed change has amodest effect on the stringency of the EEP allowance.

246
247

Per stakeholder request, EPA has also clarified that color gamut support is measured per Section 5.18,
Color Gamut Area, of the Information Display Measurements Standard.

Worldwide there is high demand for gaming monitors with large-format screens (24 inches and above)with high and variable refresh rates, GPU synchronization, or curved screens.1 To date, monitors
intended for gaming applications are covered under the scope of the ENERGY STAR Display
specification. Due to the growing market of gaming monitors and stakeholders interest in these monitors,
EPA is evaluting additional data for these products that may not currently be included in the existing
Version 7.0 ENERGY STAR dataset. EPA seeks feedback and data to support feedback on the following
questions:

255
256
257
258





If a monitor is marketed as a 'gaming monitor,' what are the features that distinguish it from a non­gaming monitor including information on their features, power consumption, and usage patterns?
Does the 'gaming monitor' require incremental hardware-based assistance?
Is the ‘gaming monitor’ capable of adjusting refresh rate with the frame rate of video content?
