A low energy class is a reason to check a monitor’s actual consumption, not proof that it will be unusable or ruin your electricity budget. The EU label gives useful comparison figures for SDR and HDR; your real cost depends on how you use the display and what you pay for electricity.
What a poor energy class actually tells you
In the EU, electronic displays are labelled from A, the most efficient class, to G, the least efficient. The European Commission describes the scale as covering “televisions, computer monitors or digital signage displays.” The letter is an efficiency classification; it is not, by itself, a forecast of your electricity bill.

The label also shows more useful detail: separate SDR and HDR efficiency classes and energy consumption, screen diagonal, and resolution. The consumption figures are stated in kWh per 1,000 hours and rounded to the nearest whole number. Read the figures for the mode you actually use rather than stopping at the letter.
Crashes, No Sound, or Screen Glitches?

That is guidance about the label context, not a guarantee that every monitor or HDR workload will use exactly twice as much. HDR settings, brightness, content, and the display itself all matter.

How to turn the label into a personal cost estimate
The label’s kWh-per-1,000-hours figure is a comparison point, not a bill calculation. To estimate your own use, take the relevant consumption figure and scale it by your hours in that mode; then multiply the resulting kWh by your electricity price per kWh. If your use is split between SDR and HDR, estimate each separately and add them. This remains an estimate: your settings and content may differ from the conditions represented by the declared figure.
A class alone cannot tell you the cost because it does not encode your hours of use or tariff. Nor can I claim a personal bill impact here: the exact monitor, its measured consumption, usage hours, and electricity rate are not specified.

Mini-LED is not a power-consumption figure
“Mini-LED” describes a display technology, not a single power profile or energy class. Manufacturer figures show why model-specific checks matter, but they are not directly interchangeable: they may refer to different conditions, brightness levels, or kinds of specification.

|---|---|---|
| Cooler Master GM27QPA | EPREL lists 26 W SDR and 28 W HDR for a 27-inch, 2560 × 1440 LED LCD monitor. | One registry listing; it is not a mini-LED-specific or category-wide benchmark. |
| TCL 27G74 | TCL describes a QD mini-LED monitor with 600-nit peak brightness and local dimming; the cited product page does not give an energy-label figure. | Features alone do not establish its energy class or consumption. |
| INNOCN 32M2V | INNOCN states 75 W typical and 215 W maximum power consumption, with brightness of 450–1000 cd/m². | These are manufacturer specifications, not independent measurements, and should not be treated as figures for every mini-LED monitor. |
These examples do not establish that mini-LED monitors as a group are necessarily power-hungry or efficient. Compare the exact model’s label and specifications, and keep the mode and measurement context in view.

What to check before deciding
- Find the exact model and regional version. Product names can cover different SKUs; make sure the label or registry entry matches the display you are buying or using.
- Scan the label QR code or search EPREL. The European Product Registry for Energy Labelling provides model-level details, including standby consumption and panel technology.
- Compare the mode you use. Look at SDR and HDR kWh per 1,000 hours separately, along with the corresponding classes.
- Compare like with like. Use the label’s diagonal and resolution to put consumption figures in context, and consider the brightness and local-dimming capabilities you want.
- Apply your own hours and tariff. A high-use HDR setup and a few hours of SDR use are not the same household scenario.
EU labels and EPREL entries concern the relevant EU model and jurisdiction; other regions may use different labelling rules. Check the current registration and regional SKU rather than assuming a label applies everywhere.

Standby and off-mode limits are separate from on-mode energy-label consumption. A 2023 EU regulation sets limits, within its scope, of 0.50 W in off mode initially and 0.30 W after two years. Those figures do not describe the monitor’s active draw and cannot be used to infer its consumption while displaying an image.

Why the rating doesn’t scare me
I would not ignore a poor class, but I would not treat it as a verdict either. The letter is one part of the picture; the SDR and HDR consumption figures, the display’s size and resolution, and my own pattern of use tell me more about whether the trade-off makes sense. Mini-LED does not supply a universal wattage, so the sensible decision is about the exact monitor—not the technology label alone.
