I just realized that his tiny screen consumes 120W when turned on.

Does any of you have a recommendation for a screen that doesn't consume so much energy?

This monitor has high power consumption because it's geared towards professionals with its high brightnes and colour correctness.

I checked the power brick and datasheet on my LG 27GP950-B and the ratings are 110W and 86W(HDR mode) respectively.

Are you after a physical tiny screen doing 4K/retina or after something huge not retina?

My LG 38" does 3840x1600. I'm using it since five years now and I much prefer to work on that than to work on my M1 Mac laptop's tiny retina screen. The 38" consumes less than 50W without being set in eco mode.

I use 19" 5:4 Eizo and 15" 4:3 Beetronics, they are 9-21W and 13.8W respectively.

My monitor (ASUS ProArt PA278QV), which calls itself "professional", has a power consumption of less than 20W. Even if his monitor has higher resoltion and better brightness, I am a bit surprised that the difference is that big.

Your comment made me check my own (LG Ultrafine 5k) and it’s 140W… That’s crazy. I love this monitor, but am interested in a high quality, lower power option if anyone knows of one.

Did you really measure these 140 W or does the power brick says 140 W?

My LG monitor has a brick that goes to 65W, but the measured power consumption is ~20W at the wall. ~12W in short idle (screen turned off less than ~1 min ago). ~0W in deep sleep, which is where it spends most of its time.

I am running on minimum brightness, since I'm indoors.

Crazy? At 20 cents/kWh, running it for 12 hours a day costs 34 cents per day or $123/year.

My entire house idles at 500W.

That includes two fridges, a freezer, a NAS, multiple internet uplinks, lighting, an always-on desktop, a half-dozen IoT gizmos and five wireless access points.

The house averages 1-2 kW (including laundry, water heater, water treatment, hvac, dishwasher, oven, cooktop, etc).

A 140W monitor would meaningfully increase these numbers.
