IEC 62087-7:2018

Overview

IEC 62087-7:2018 specifies standardized methods of measurement for the power consumption of computer monitors. It covers mains‑powered displays (CRT, LCD, PDP, OLED and touch‑enabled monitors) intended to show video signals from computers and excludes battery‑powered devices and network/wireless‑only monitors. The standard defines test procedures using static test patterns, dynamic video loops and web‑based video, and describes the operating modes relevant to measuring power (on, partial‑on/standby, off).

Key topics and technical requirements

The standard sets out measurable conditions and procedures to ensure repeatable, comparable power measurements:

• Scope of devices: mains‑powered computer monitors (no TV tuner); digital (DisplayPort, HDMI, DVI) and analogue (VGA) inputs supported; specialized medical or industrial monitors excluded.
• Operating modes: definitions for on‑mode, partial‑on/standby modes and off‑mode, plus behavior of automatic brightness control (ABC) where present.
• Measurement conditions: requirements for power supply, environmental conditions and ambient light to represent normal use.
• Measuring equipment: specification of power meters, luminance and illuminance measurement devices and signal generation equipment.
• Test content: static patterns, broadcast/dynamic loops and web‑based video for realistic on‑mode testing; procedures for disabling/enabling ABC and setting picture controls.
• Test procedure details: preparation, stabilization/cool‑down, order of activities, determination of on‑mode, partial‑on and off‑mode power consumption, and power factor measurement.
• Repeatability and accuracy: guidance on signal generation accuracy, light source configurations and measurement tolerances to ensure consistent results.

Practical applications and who uses it

IEC 62087-7:2018 is used by:

• Manufacturers and design engineers for product development and power optimization of monitors.
• Test laboratories and certification bodies performing standardized energy measurements and compliance testing.
• Regulators and energy programs for energy labeling, minimum performance standards or efficiency benchmarking.
• Procurement and sustainability teams evaluating monitor energy use for corporate purchasing or green procurement.

Benefits include reliable comparison of display energy use, support for energy labeling and regulatory compliance, and guidance for assessing ABC and typical real‑world video workloads.
